What’s with all the cows?

©iStockphoto.com/Eric IsselŽe

We all trot off to work each day and, no matter how much we enjoy what we do, there is always a repetitive factor. Some of us have fairly low tolerance to repetition and boredom so we invent ways of keeps ourselves entertained. In many ways my job is the antithesis of boredom as I am tasked with finding out “what’s new” - but converting this into text and images for the web and magazine is repetitive. So, many years ago, simply as private entertainment, I decided to include an image of a cow in every issue of the magazine. This went well for a while but then it escalated … I moved on from single cows to multiple cows - rather than using conventional ‘stops’ at the end of every article I used cows. Cows were proliferating. Then the art team became involved - for a while we contented ourselves with all sorts of different ‘stops’ but the need for cows was still simmering on the backburner. My private entertainment had become public and people started giving me cow-related gifts. Now I am in bovine overkill. At Foodtech Packtech, What’s New in Food Technology & Manufacturing has a stand. It’s a great opportunity for me to actually meet the magazine and website readers and I always come away from such meetings both enriched and humbled by the knowledge, interest and professionalism of the readers I meet. In return I would like to portray a professional persona as befits the editor of the magazine and website. But what has happened? Cows! Our Events team procured little giveaways to entice potential new subscribers to our stand - cow stress balls - and I have succumbed to temptation and put an illustration of a cow reclining in a sun chair on the front cover. If you are in Australia rather than New Zealand you won’t get this cover because the publisher has placed a moratorium on my cow - declaring that we are a reputable business and cutesy cows do not align with our image. I have to say he is right. What’s New in Food Technology & Manufacturing is not cutesy and you can help in ensuring it stays that way. When you or your company does something newsworthy in the food and beverage industry, let me know. Send me a press release and a picture so I can publish some serious Australian and New Zealand content about how you are meeting and beating the challenges of manufacturing foods and beverages. And from now on, I am limiting my cows (but I am developing an alternative keep your eyes peeled in coming issues and let me know if you see a subtle theme). Regards Janette Woodhouse Chief Editor

No health claims allowed on sugary, salty and fatty foods, forum decides The Legislative and Governance Forum on Food Regulation met on Friday 20 July to discuss general level health claims in the draft Standard for Nutrition, Health and Related Claims. The forum, composed of ministers responsible for food regulation in Australia and New Zealand, reached agreement on a preferred approach for a system regulating general level health claims. The approach includes pre-approved food-health relationships and the option for food producers to self-substantiate new claims that comply with detailed criteria set out in the standard. The ministers confirmed their support for a nutrient profiling scoring criteria (NPSC) that would ensure only healthy foods carry health claims. Foods high in sugar, fat and salt would be precluded from claiming health benefits. The review period for the standard has been extended until 31 October 2012.

Microwaving retains RPO’s carotene content, study finds

thought

Microwave heating of red palm oil (RPO) retains a higher carotene content than RPO that has been conventionally heated, researchers at Universiti Teknologi MARA in Malaysia have found. The researchers conducted a study to evaluate carotene and the antibacterial effects of microwave heated and conventionally heated RPO. They found that heating RPO decreased its carotene levels, but microwave heated RPO retained higher carotene content. The study also found that neither fresh nor heated RPO exhibited inhibitory effects on Escherichia coli bacterial growth. As a result of the study, the researchers recommend conventional heating be replaced with microwave heating as part of a health red palm oil diet. The research paper was presented at the 2012 IEEE Symposium on Humanities, Science and Engineering Research in Kuala Lumpur.

GS1 announces global product recall standard ©iStockphoto.com/ Alexander Chernyakov

Following nearly three years of industry-driven work, GS1 has announced the ratification of a new global product recall standard, as well as an implementation guide for multijurisdictional recall notifications. GS1 Australia said the new standard ‘connects’ all the recall portals being developed across the globe, enabling the exchange of data between portals. GS1 says the standard will enable supply chain stakeholders to implement more effective product recall processes and notifications. “The standard defines, standardises and harmonises the critical attributes to be captured and shared among trading parties and regulators during a product recall alerting and

September/October 2012

messaging process,” GS1 said in a media release. “Effective product recall is complex, multijurisdictional and typically involves multiple stakeholders in extended supply chains,” said a Woolworths Australia spokesperson. “Having a standardised process globally will enable us to run more timely and targeted recalls. Ultimately, consumer safety will benefit.” The standard identifies the key principles of traceability and demonstrates how to apply them for effective product recall. Accompanying the standard is an implementation guide that is dedicated to multijurisdictional requirements as a product recall alert is issued and executed. “The GS1 Product Recall Standard will enable manufacturers, retailers and suppliers to work more closely together,” said Procter & Gamble’s Marketing Logistics Leader Daniel Triot. “By leveraging a system of global supply chain standards that we all know and use today, product recall will become a function that is embedded into all our global supply chain. Critical mass adoption and interoperability of the notification tools will accelerate the implementation of the standard.” The standard is incorporated into the GS1 Recallnet platform in Australia. GS1 Australia’s COO Mark Fuller says this is part of GS1 Australia’s long-term plan for making GS1 Recallnet a more global solution for brand owners and consumers.

Lactose-free dairy products:

not an oxymoron, but a growth area While ‘lactose-free dairy products’ might sound like an oxymoron, apparently it’s a huge growth area. Innova Market Insights has reported that global launch numbers for lactosefree dairy products more than tripled in the five years leading to 2012. In 2007, lactose-free dairy products accounted for less than 2.5% of total dairy introductions; by 2012, they made up 4.5% of total dairy introductions. Interest in lactose-free dairy products has been highest in the USA and western Europe, with 10% and 6% respectively of total dairy launches in the past 12 months being marketed as lactose-free. Lu Ann Williams, Research Manager for Innova Market Insights, puts the growth down to several factors: interest in dairy alternatives, improved labelling, growing awareness of the potential problems associated with lactose intolerance and technological developments allowing the

production of better-tasting products. Rather than just being focused on the specialist dietetic market, lactosefree products are now moving into the mainstream. Large companies have extended their brands with lactosefree alternatives: Danone’s Activia now comes in a lactose-free option, Yoplait has four lactose-free variants and New Zealand’s Anchor dairy brand has released two Zero Lacto lactose-free alternatives. Already established dairy alternative sectors have the highest share of lactose-free ranges, particularly beverages, with over 30% of products marketed as lactosefree. Creamers accounted for over 9% of introductions in the beverages subsector. Williams says the increasing presence of lactose-free options in mainstream dairy markets will drive both the dairy sector and the food and drinks market forward.

CSIRO forms new division

co m

de r ny he rC

ak ov

CSIRO has announced a new research addition: a Division of Animal, Food and Health Sciences. The new division is an amalgamation of the former divisions of Livestock Industries and Food and Nutritional Sciences. In the months leading up to the official 1 July formation of the new division, staff from the two former divisions have been working together to ensure a smooth transition. CSIRO says all projects and agreements will continue and staff contacts for partners and clients will remain the same. Leading the new division is Dr Martin Cole, Chief of Food and Nutritional Sciences and an internationally recognised microbiologist. Cole says the 568 staff from the former divisions will form one of the most comprehensive cross-disciplinary life science capabilities in the world and maintain CSIRO’s unique position in the whole of food-value-chain research. “Just as the last century has seen a revolution in computing, biology is experiencing a major wave of technical innovation

flowing from the significant advances made in the life and computational sciences. Our capacity to understand complex processes in a highly targeted manner is vital to our capitalising on opportunities in the food, health and life science industries,” Dr Cole said. “This new understanding will have profound impacts on animal production and health, human nutrition, and prevention of infectious and lifestyle diseases. The new division will allow us to capture these opportunities. It will connect primary production to food processing and manufacturing and consumer needs. “This is something more than a merger. This is about creating a division that affords new science approaches that more effectively provide our clients and research partners with the greatest benefits,” Dr Cole said.

Guideline changes mean dollar-for-dollar grants for manufacturers gas emissions and face a direct carbon price liability under the $1 billion Clean Technology Investment Programs. Greg Combet, Minister for Industry and Innovation, announced the update to the program guidelines yesterday. He said the new funding ration would increase support for manufacturers to invest in equipment and technology to reduce their power bills and emissions. “The change in the Clean Technology Investment Programs’ grant ratio has been made after detailed consultations with industry. It will ensure manufacturers who are directly liable under the carbon price are able to apply for significant assistance under the Clean Technology Investment programs,” Combet said. “Capital investment in low-emission and energyefficient technologies throughout manufacturing

facilities will help these Australian businesses to become more competitive and sustainable.” The changes to the guidelines mean that manufacturers with a facility that emits between 25,000 and 100,000 tonnes of greenhouse gas emissions in the full financial year prior to lodging their application now only have to match the government grants on a dollar-for-dollar basis. For businesses that meet the criteria and have already lodged an application under the Clean Technology Investment Programs, the new funding ratio will be available retrospectively. Existing grant funding ratios will continue to apply to businesses not liable under the carbon pricing mechanism. Manufacturers with a turnover of less than $100 million applying for grants under $500,000 will continue to receive a dollar-for-dollar grant ratio. The Clean Technology Investment Program and the Clean Technology Food and Foundries Investment Program are open for applications. For more information, visit the AusIndustry website.

Supermarket private labels will keep growing, says IBISWorld Private-label products will increase to cover 30% of the market in the next five years, IBISWorld predicts. The market research group forecasts that private-label products will increase from just over one quarter to over 30% of total supermarket sales by 2017-18. Karen Dobie, IBISWorld General Manager (Australia), says private-label products have been one of the fastest-growing segments in the supermarket industry in the past decade. The rising cost of living, compounded by the carbon tax, will see more Australians opt for private-label products, Dobie predicts. “In 2007-08, private labels accounted for just 13.5% of total supermarket sales - meaning the segment has grown by more than 85% over the past five years,” Dobie said. Of the $85.9 billion Australians are expected to spend on groceries in 2012-13, IBISWorld predicts $21.6 billion will be spent on private-label products. Ths is up from $9.96 billion five years ago and $19.7 billion in 2011-12. By 2017-18, Dobie expects this will reach $31.8 billion - a growth of nearly 50% in five years.

September/October 2012

“The recessive economic climate has been a strong driver of private-label growth,” Dobie said. “Households have been reining in spending, paying off debt and increasing savings. This, coupled with an increase in the range of private-label products available, has led many consumers to make the shift to home brands.” Within the private-label segment, dry grocery items and chilled packaged food categories have shown the strongest growth. Alcohol has also worked well for Woolworths and Coles, Dobie said. “Products with a high degree of homogeneity that are staples of grocery baskets have shown the strongest private-label growth. These include private-label butter, which accounts for 68% of total butter sales; private-label sugar, accounting for 67% of total sales; bread at 56%; and fresh milk at 55%,” Dobie said. The consumer trend towards free-range eggs has seen privatelabel egg sales decrease from 61% to 50% of market share in the past ten years. Consumer preference for trusted brands in chocolate, confectionery, soft drinks, cosmetics and sanitary products means these categories have not performed well. Dobie also commented on the supermarket price wars, saying that consumers will benefit from cost savings in the short term, but may be faced with less choice longer term as supermarkets increase their private label ranges. “All of this discounting means that someone is paying the cost of purchasing $1 litres of milk and $2 loaves of bread,” Dobie said. “More often than not, farmer and producer margins are being squeezed as supermarkets discount heavily to increase store traffic.” Heavy discounting strategies, such as Coles’ flybuys program, are often detrimental to suppliers. “In the long term, this trend will primarily benefit the supermarket giants and those producers that are contracted to manufacture private-label products,” Dobie concluded.

What: Foodtech Packtech When: 25-27 September 2012 Where: ASB Showgrounds, Auckland Online registration for free entry: www.foodtechpacktech.co.nz Foodtech Packtech is a must-attend event!

N

ew Zealand’s biennial Foodtech Packtech exhibition gives food sector professionals the opportunity to come face to face with the experts behind the key innovations entering the New Zealand and Australian markets. The event will showcase the freshest ideas, latest technologies and the newest developments entering the food technology and packaging technology market from more than 180 prominent suppliers. A series of development and business seminars will also run, and Foodtech Packtech 2012 is endorsed and supported by the Packaging Council of New Zealand, the New Zealand Institute of Food Science and Technology, and Plastics New Zealand. Many exhibitors are keeping secret for now what visitors will see, but some are prepared to offer a teaser or two into the products and services they’ll have on their stands. You can rest assured that there will be plenty of extra-tempting show specials on some of these, too. No matter your business or interest, there will be something to pique your interest at Foodtech Packtech 2012. D&L Packaging’s Digby Morton says visitors to their stand will see a few interesting technologies. “We are offering the latest in shelf life boosting (SLB) technology, including vacuum packaging, tray sealing/ packing, skin packing and thermoforming, and the latest tray lidding barrier films. These technologies greatly extend shelf life to most fresh food products, while maintaining the quality and freshness of the food and all without the need of additives. Clearly there are great advantages for both food producers and consumers. “Odour control technology is another area of huge interest to the sector and many others. We have a brand new, never seen before range of products for odour control. This product is an odour absorber unlike anything else on the market. Our product actually absorbs the odour and does not simply mask the odour by creating clouds of perfumed mist. This product can be used in virtually any building,

Biopolymer derived from renewable plant resources NatureWorks’ Ingeo biopolymer is derived from an abundant 100% annually renewable plant resource. Carbon is captured in these plant resources, sequestered from the atmosphere during plant photosynthesis, and stored in the starch found in the grain of the plant. This starch is then converted into natural sugars. NatureWorks uses this plant sugar, dextrose, from a simple existing supply stream as Ingeo’s fundamental building block. Through a process of fermentation, separation and polymerisation, the carbon and other elements in these natural sugars are transformed into Ingeo biopolymer. According to NatureWorks, Ingeo resins and fibres are a significant step towards a better future. Replacing petroleum with an annually renewable resource for the production of plastics and fibres reduces fossil fuel dependency and is a positive step towards carbon-neutral manufacturing and more sustainable processes and products. The production of Ingeo uses significantly less non-renewable energy and generates significantly lower CO2 emissions when compared with all traditional oil-based polymers. Compared to PET, for example, Ingeo reduces fossil fuel usage by 47% and greenhouse gas emissions by 59%. Ingeo biopolymer is used to create a full and diverse range of finished consumer lifestyle goods from clothing to housewares to personal care products as well as food packaging, appliances, auto parts, consumer electronics and durable goods. NatureWorks will showcase its Ingeo biopolymer at Foodtech Packtech 2012. NatureWorks LLC www.natureworksllc.com

Chemical delivery system for water treatment Ashland Water Technologies has launched a solid chemical delivery system designed to provide food and beverage producers with more sustainable and environmentally friendly chemical water treatment solutions. The Ultra-Serv Solid uses an easy-to-install solid chemical delivery system that replaces liquid water treatment chemistries with a 100% active solid product. The dissolver system is loaded with 3.5 kg solid chemical discs that are sprayed with water

FOODTECH PACKTECH

to dissolve the chemical into a small volume of liquid, ready for application through the existing chemical dosing and control system. The dissolver system overcomes the problems associated with other solid chemical systems and the company claims the system has proved highly reliable in the 200plus applications currently in place. By using solid product, the volumes of chemical that need to be shipped and managed are typically reduced by between 50 and 90%, depending on the application. This large reduction in chemical volume lowers freight requirements, and reduces fuel consumption and CO2 emissions. This, in addition with the elimination of plastic pails and drums, can assist food and beverage companies in improving their carbon footprint and supporting their sustainability goals. Ultra-Serv Solid has been demonstrated to reduce environmental and health and safety risks by eliminating potentially hazardous liquid spills and eliminating the need for workers to handle heavy containers. Inventory management is also streamlined as less chemical storage space is required and the handling of solid product is much easier and reduced compared to handling pails and drums.

Hot topics in food packaging

FSANZ announces decision on country-oforigin labelling for unpackaged meat Unpackaged beef, sheep and chicken meat could soon be required to have country of origin labelling. Food Standards Australia New Zealand (FSANZ) has approved a proposal to extend country of origin labelling to some unpackaged meats. Food regulation ministers have been notified of the decision and have 60 days to seek a review. If no ministers seek a review, the decision will become law in Australian states and territories. There will be a six-month implementation period once the change is gazetted. The Australian Government asked FSANZ to address an inconsistency in country of origin labelling requirements for unpackaged meat after the rules for beef imports were changed in 2010, said FSANZ CEO Steve McCutcheon. FSANZ was also asked by food regulation ministers to continue this work following the recommendations of an independent review of food labelling headed by Dr Neal Blewett. “Research indicates country of origin information is important to consumers and is valued more in fresh food products such as fresh meat than other food categories,” McCutcheon said. “Mandating additional country of origin labelling requirements will ensure consumers are provided with access to this information consistently across the retail sector.” Many retailers already label products voluntarily, McCutcheon said, so the cost to industry as a result of the change is unlikely to be large.

Compostable biopolymer trials show extended brassica shelf life Cantankerous cauliflower could soon be a thing of the past. A new film for packaging fresh produce has performed well in trials with brassicas, which tend to deteriorate after just one day on the shelf. In the trials, Sirane’s Sira-Flex Resolve was used to package cauliflower and broccoli. The produce was found to be in good condition five days after packaging with the film. Cabbages, leeks and carrots gained two days of shelf life with the packaging. In Australia, where long transport distances and high temperatures can shorten shelf life, Sira-Flex Resolve trials showed a shelf life extension of more than 20 days, Sirane’s Managing Director, Simon Balderson, said. “Initial tests using the film showed the produce had a remarkable shelf life extension when compared with existing products. We await further trials with interest,” said Balderson. The film is a fully compostable biopolymer. According to the company, it has been developed to give the optimum balance between humidity control and O2 and CO2 permeability. The film’s permeability to humidity, O2 and CO2 is apparently different in each case, being affected by storage conditions and other variables. “The unique structure means we are getting some varied results on shelf life extension,” Balderson said. “Because the results are very specific to the conditions, we are finding it difficult to advise on just what the shelf life extension potential is. “Where one person might get two days, another might get 10 days, as it depends so heavily on the various factors at play in relation to storage conditions and other variables.” Sirane is encouraging people to run their own trials to assess how the film will benefit their operations. The film could reduce food waste and costs, Balderson said, making it more likely that the consumer will receive the produce in good condition. Balderson says Sira-Flex has broken new ground, delivering packaging that will keep food from drying out, eliminate ‘fogging’ within the pack and ensure no mould or bacteria growth on the produce.

Sustainable benefits and It’s a fact: consumers prefer minimal packaging ©iStockphoto.com/Michael Bodmann

A 17,000-person survey covering 17 nations, the 2010 Greendex research study from National Geographic and GlobeScan found 40% of consumers avoid excessively packaged goods “all” or “most of the time”. Another survey, the Natural Marketing Institute’s 2011 LOHAS Consumer Trends Study, found 75% of Americans believe many consumer products are overpackaged.

A

long with minimal packaging consumers like recyclable packaging, environmentally friendly packaging materials and to support consumer packaged goods companies (CPGs) that bring sustainability to the production floor with improvements to reduce energy usage or air and water waste. Following, some of the exhibitors at the upcoming PACK EXPO International in Chicago share some of their environmentally-friendly materials and innovations which can improve productivity while reducing carbon footprints.

Sustainable process improvements In many instances, changes in the design and layout of a manufacturing facility can make a difference in a company’s sustainability goals. “Environmentally sensitive design and manufacturing improves efficiency and reduces the costs of processing, inspection and packaging machinery,” says Brian Barr, Packaging Systems Sales Manager, Heat and Control. “Precision laser and water-jet cutting of materials and unitised equipment designs reduce waste, air pollution and the number of parts required

to build each machine. Modular machinery cuts the time, labour and floor space required for installation. We now also offer equipment that recovers energy from cooker exhaust and conveyor drives that can be re-used with different pans - not scrapped - when line layouts change.” QuikWater offers a sustainable direct-contact water system for heating sanitation and process water for the food manufacturing industry. “Our patented clean-burn technology outperforms traditional boiler systems on virtually every level - from improving worker safety to being more energy efficient,” says Tammy Collins, Sales Manager at QuikWater. “Whether you need as little as 20 L of hot water per minute or as much as 8500 L/min up to 93°C, there’s a system that’s right for your application. “The system is non-pressurised, so no boiler codes are required, and there is no need for special operators or AMSE stamps,” adds Collins. “It is also up to 40% more fuel efficient than typical steam-to-hot-water systems, which means less fuel and less energy are required. This lowers overall operating costs. And with a 20 to 40% reduction in carbon dioxide emissions, the system reduces a company’s carbon footprint.”

www.foodprocessing.com.au


Centrifugal blowers and air delivery devices from Paxton Products, an ITW company, provide clean dry air and reduce energy usage during packaging and labelling by as much as 80%, as compared to compressed air systems. “Each Paxton system is custom engineered for drying based on the size and shape of the target product and the line configuration,” says Barbara Stefl, General Manager at Paxton. “The devices can be configured either to deliver a curtain of air, to dry the top and sides, or with the new Air Halo, to deliver a 360° halo of air to dry top, bottom and sides at once.” Stäubli Robotics now offers the TP80 fast picker, a new series of high-speed pickers that deliver greater speeds (up to 200 picks per minute) and more flexibility at a lower cost to the packaging market. This robot is more agile and lighter weight, has extremely fast cycle time and maintains high, repeatable precision throughout the entire work envelope. A simple base or wall mounting eliminates the need for a large gantry, further enhancing cost effectiveness and ease of integration.

Hidden green opportunities Even small changes to packaging machinery can impact a CPG’s sustainability efforts. Tom Miller, Bearings Unit Manager-North America, igus, points out, for example, the benefit of switching from metal bearings to dry-running plastic bushings, which do not require lubrication and require less energy to produce. “These days, many companies are working hard to reduce their carbon footprint on the environment, but this does not happen overnight,” says Miller. “It is usually a culmination of changes that take place over time, in a number of different areas. Even small changes to the design of a packaging machine can make a difference. “We offer an FDA-compliant bushing material that is blue in colour for easier detection,” says Miller. “The iglide A350 plastic bushings are highly wear resistant and can handle long-term temperatures up to 180°C. They are suitable for applications in the food, packaging and bottle-filling industries. They deliver low coefficients of friction and are resistant to a variety of chemicals and other liquids. “They are also extremely lightweight, which helps reduce fuel consumption and carbon dioxide output,” he adds. “And they do not require environmentally harmful galvanising baths to achieve chemical resistance, unlike metals that often have to be coated using an environmentally unfriendly, high-energy zinc galvanising bath to achieve this effect.”

Tom Duffy, National Sales Manager, Badger Plug, says, “The scope of package sustainability should include recycling and the re-use of packaging components as part of the need to reduce waste and save money. Today, manufacturers and converters of film, paper, metals, textiles, etc consume large amounts of packaging that can often be recycled. Roll protection products such as core plugs and suspension packaging need to be part of the sustainable discussion. “An experienced provider of recycled packaging can help avoid the pitfalls that can occur when dealing with recycled/ used packaging,” adds Duffy. “Low-cost packaging components such as single-core plugs are generally difficult to re-use due to freight costs, damage and cleanliness. More expensive suspension components such as end boards, sleeve plugs, pallets and channels/clips are readily recycled. Everyone in the business transaction can find value in this recycling process. Plus, the impact on our environment is greatly reduced.”

Eco-friendly, food-specific package modifications An increasing number of shoppers are seeking out coffee products produced and harvested in a sustainable manner - including beans grown in a manner that is kind to the environment and its people. Coffee marketers who want to take this to the next level also want sustainable packaging options, such as the Flexis Air valve from Avery Dennison Designed and Engineered Solutions. “Flexis technology allows for up to a 30% increase in application throughput and a 30 to 50% product purchase advantage over hard valves,” claims Nick Greco, Business Development Manager at Avery Dennison. “Plus, they offer exceptional performance characteristics. Tests conducted by a major university show that the valve maintains less than 2% residual oxygen for 24 months, equalling the reliability of hard button valves.” The Flexis Air valve employs about 90% less plastic than injection-moulded plastic degassing valves, creating another opportunity to reduce carbon footprints and non-recyclable waste. The valves are also pre-oiled with a precise amount of food-grade silicone oil at the necessary valve location to protect against oxygen ingress. The pre-oiled feature can save time and reduce scrap and clean-up by eliminating the need to oil valves during the packaging process. Sustainable advancements in can packaging of ground coffee, milk powders such as infant formula and other dry, powdered products include technologies that reduce the use of typical gases required for a modified-atmosphere environment.

The Cognex In-Sight 7000 series vision systems are used to improve product quality, drive down costs and comply with product and package safety requirements such as traceability and label verification on food and pharmaceuticals. example, the INDOSA Can Process Center (CPC) 127-10 ProVac from Grabher INDOSA AG uses proprietary vacuum technology. “The high efficiency is guaranteed by 10 stationary workstations, which are in use more than 90% of the process time,” says Michael Grabher, Vice President of Grabher INDOSA. “The system includes evacuating, gassing and seaming, and allows the customer to vary the end pressure inside the can. With this technology, it is not necessary to use carbon dioxide, as the underpressure of each can is adjustable and less than 0.5% oxygen content can be achieved.” He adds that nitrogen consumption is reduced to a minimum, because each can is gassed in a separate stationary chamber only slightly larger than the can - improvements in efficiency and gas use that reduce a canner’s carbon footprint. For baggers of milk powders or other dried ingredients such as bakery mixes, flour, soy protein, starch, spices, sugar, etc, Premier Tech Chronos has recently developed the BFW Series Open-Mouth Bagger with Bottom-Up Filler, a sustainable solution for the bagging of powdery materials. This innovative system is the combination of a hygienic vertical main feeder (meets 3A standards), FANUC Robot(s) and a bottom-up filling system. “It is certainly the best hygienic approach in the industry and has a very high accuracy on weight (up to ±15 g),” says Yan Gagné, Engineering Supervisor at Premier Tech Chronos. “It can produce airtight bags for long-term storage and is equipped with a large bag magazine that provides long-production runs, very few modules and a great floor clearance. “Furthermore, the BFW Series provides both versatility and speed since it can handle paper, polyethylene, laminated polywoven and Cap-Sac (a PE bag within a paper bag) bags at up to 12 bags/min, depending on products, bag sizes and applications,” says Gagné. “Complete control on side-gusseted pinch top bags is achieved; no gusset realignment device is required.” As the EPA tightens rules and regulations on conventional aerosol hydrocarbon propellants, the bag-on-valve package (BOV) is a growing trend in the aerosol industry. “A rolled up aluminium bag is welded or attached to an aerosol valve,” says Jim McBride, owner of MBC Aerosol. “Compressed air is charged into the can and an aerosol valve with the bag attached is crimped onto the container. The product is forced through the aerosol valve stem to fill the bag. When the spray button is pressed, the product is squeezed out of the bag by the compressed air, which creates the aerosol spray via the spray button orifice. “The major benefit of this package is the lack of volatile organic compounds,” McBride says. “The other benefit is that 24

Plus, about 99% of the product is squeezed out so the only thing left is aluminium and 30 to 40 psi of compressed air. A variety of foods are making their way into this package, including olive oils and salad dressing.”

Getting green through package processing modifications Sometimes a modification to a current packaging process can assist with saving money, materials and energy. Vacuum Barrier now offers Nitrodose Liquid Nitrogen Dosing Systems, which allow manufacturers to use the most lightweight PET and aluminium can packaging by providing the most precise liquid nitrogen dosing at the highest discrete dosing speeds. “This eliminates liquid nitrogen waste and reduces consumption by having a very low LN2 delivery pressure along with both speed and dose compensation,” says Edward Hanlon Jr, Vice President Sales at Vacuum Barrier. “It also allows for a reduction in packaging materials.” Induction heating is a method of providing fast, constant heat for electrically conductive materials. Although the basic principles of induction are well known, modern advances in technology have made induction heating a remarkably simple, cost-effective heating method. Formost Fuji has adapted this technology to sealing film on its horizontal wrapping machine. This technology has reduced the cost of maintenance, increased the reliability and stability of the heater system, reduced energy usage and greatly extended the useful life of the parts. In addition, through the reduction of moving parts, the component is much less complicated, which all adds up to a better system. In a bid to reduce the amount of material used to seal plastic packages, ultrasonic sealing technology, which has been around for more than 50 years, is now being used more frequently in packaging. New and innovative solutions reduce the amount of material being used for packaging and ultrasonic sealing reduces power consumption while improving overall equipment efficiency (OEE). Installed applications include bagged salad, beverage, coffee, dairy, pasta, readycooked meals and powdered products. “For vertical form-fill-seal (VFFS) machines, ultrasonic allows welding through contamination on the cross seal this results in less headspace for the package and reduced sealing width,” says Uwe Peregi, Executive Vice President and General Manager, Herrmann Ultrasonics. “Thanks to the feedback on the ultrasonic technology, each seal is validated

with modern generators, which allows statistical process control monitoring. Further, the molecular weld process starts from the inside layer, which results in reduced sealing time and less abrasion of the film.”

Ensuring label accuracy Due to miniaturisation and advances in the power of digital signal processors, imaging sensors and decoding algorithms, traceability applications such as ID code reading, text verification, mark quality assessment and label inspection can now be accomplished more economically using the latest generation of smart camera vision systems. “The most advanced of these smart camera vision systems now offer advanced networking, communication capabilities and powerful factory integration tools,” says John Lewis, Market Development Manager, Cognex. “And with a standard operator interface for a common look and feel across all packaging lines and inspection points, many packagers and materials suppliers now consider smart camera vision systems indispensable in their efforts to build strategic information architecture in line with corporate sustainability goals.” Such vision systems help reduce defects and eliminate scrap, he adds. “It’s really better for the environment to use machine vision, but it’s also better for the manufacturer because it

reduces production costs by increasing manufacturing yields to help them achieve their corporate sustainability goals.” For example, label, material and container suppliers use a lot of vision systems and image-based barcode readers. Suppliers of pre-printed labels, injection-moulded bottles, flexible films and carton-board containers use vision to eliminate misprints and mix-ups. Packaging materials including onserts and inserts are often furnished pre-printed with barcodes and characters that must be verified. Label-converting companies use vision and image-based barcode readers to ensure code quality and data integrity on their serialised labels. Mistakes on any of these items can result in costly FDA-mandated recalls.

Compostable coffee packaging solution Innovia Films’ compostable, cellulose-based material NatureFlex is helping a New Zealand coffee roaster meet its commitment to being socially and environmentally responsible. Caffe Prima, based in Christchurch, has chosen to use Econic coffee bags. The bags were specifically developed by New Zealand converter Convex Plastics, using NatureFlex renewable and compostable films in their construction. “Coffee is a very demanding product to package because maintaining freshness and taste is absolutely paramount. Packs have to be puncture and impact resistant and offer high barrier and good seal integrity to keep oxygen out and aroma in. Coupled with this, Caffe Prima was looking for a solution that was kind to the environment. NatureFlex ticked all the boxes as far as we were concerned,” said Andrew Sheerin, Technical Manager, Convex Plastics. A laminate construction was produced using three flexible films that are certified compostable and renewable - reverse printed clear NatureFlex, high-barrier metallised NatureFlex and starch-based biopolymer. NatureFlex films are certified to meet the American ASTM D6400, European EN13432 and Australian AS4736 standards for compostable packaging. The wood pulp is sourced from managed plantations from referenced suppliers operating Good Forestry principals (FSC or equivalent). The renewable bio-based content of the films is typically 95% by weight of material according to ASTM D6866. It has been confirmed as suitable for emerging ‘waste to energy’ techniques such as anaerobic digestion. NatureFlex was a good solution for this application as the film begins life as a natural product - wood - and breaks down at the end of its life cycle in a home compost bin or industrial compost environment within weeks.

Tattoo design on bottle uses cold-activated ink technology

Chromatic Technologies Inc

PACKAGING

Specialised inks company Chromatic Technologies Inc (CTI) has made a lasting impression on a liqueur from Tuaca. The bottle’s lion, a classic brand image for Tuaca, was redesigned as a thermochromic feature for the label on the limited-edition bottle. The ‘Perfect Chill’ bottle has met with exciting consumer response since its introduction in 2011, and has been showcased on Tuaca’s ‘Drinks & Ink 2012: A Celebration of Tattoo and Cocktail Artistry’ tours with celebrity tattoo artist Corey Miller. Miller created the custom design that adorns the Perfect Chill bottle, which was printed by Eurostampa of Italy at its North American facility in Cincinnati. The unique design of the lion shifts from a silver colour at room temperature to a stunning, vivid blue when chilled to 8°C, when the product is at peak serving for consumers. The ‘tattoo’ - using the thermochromic inks supplied by CTI - is printed on a label which adorns the bottle. CTI’s ‘thermochromic’ process uses cold-activated ink technology to convey messaging, be it an indication of cold temperatures or an extension of the product’s brand. CTI’s technology also provides for the reverse process, wherein hot beverages will display a signal on the package or label. CTI’s thermochromic inks are applied in diverse applications such as security and anticounterfeiting, food and beverage packaging, and many other types of consumer packaging. Another CTI capability, photochromic ink (ink colour changes due to exposure to UV light from the sun) is largely used in the textile market but is seeing an increase in demand for consumer packaging.

To buy or not to buy ‌ because of the challenge

Implementing OEE (overall equipment effectiveness) measures in the packaging hall

Opening packages is taken for granted by most. But Arthritis Australia asks that we all be cognisant of those members of society who struggle with opening packs. The not-for-profit organisation does an excellent task of bringing to the attention of designers the challenges some members of society have and packaging designers would be wise to take note of this organisation’s advice. Surely it is the duty and obligation of all packaging technologists and engineers to consider the needs of these consumers when designing packs for the marketplace. The response may be that such consumers are in the minority of the population. It would be wise, however, to remember such citizens are very much a part of our society. Such an attitude may be further dispelled when considering the statistics: nearly one in five Australians has arthritis. Arthritis impacts directly on 3.85 million people, or 18.5% of the Australian population. Add to this other disabilities and soon a sizeable percentage of the population is struggling with packs. There are many simple design features that could be incorporated into packaging to enhance the ease of opening: perhaps enlarging a 28 mm closure; putting a groove into the top of the closure where a table knife can be placed into the groove giving it more leverage; using tamper-evident seal labels rather than clip-lock closures or closures with a drop-down retaining bead. In flexible packing greater use can be made of easy-peel opening type film structures where the bag can be more easily pulled apart when opening. If each designer made the effort to improve the opening capacity of just one pack over the next year, the chances are sales would be directly affected by many more happy customers. You are encouraged to forward your success stories to this column where a reflection on this topic will be offered one year from now.

Large-character printer/labeller The Linx IJ355 and IJ375 high-definition case coders are two new large-character printers from coding and marking specialist Linx Printing Technologies. Claimed to be able to cut production costs while maximising line uptime and print quality, the printers provide a cost-effective, easy-to-use alternative to other largecharacter printers, and to the labelling or pre-printing of secondary packaging. The printers use ReFresh ink recirculation system, have a robust design and printhead protection technology which result in reduced downtime and savings on consumables. The ink recirculation system’s technology provides good print quality and also avoids wasted ink during printhead cleaning, thus saving time and money ordinarily wasted on purging procedures. Ink and dust that collect on the nozzles is removed with an air knife, an ink purge takes place, then ink from this procedure is collected, passed through a high-performance filter to remove impurities from the system and recirculated. Operators only need to perform quick, simple maintenance on a regular basis in order to keep the printer in optimum operating condition. The tough stainless steel nozzle guard protects the printhead from possible damage, caused by impact with the boxes on the line, while remaining close enough to the packaging to ensure print quality is maintained. The robust stainless steel lower casing and printhead protection mean the Linx IJ355 and IJ375 are robust enough to cope with the most demanding production lines, delivering savings on consumables and minimising downtime. The printers come with a full-colour LCD interface and touch-screen operator controls, with print preview and icon-based message selection. The control unit is detachable for handheld use or for mounting in a more convenient location. A set of robust accessories is also available from Linx to provide simple and accurate mounting of the printer onto the production line.

Fruit juice used to halve the fat in chocolate It may not make chocolate one of your five a day - but scientists have found a way to replace up to 50% of its fat content with fruit juice. ©iStockphoto.com/eli_asenova

U

niversity of Warwick chemists have taken out much of the cocoa butter and milk fats that go into chocolate bars, substituting them with tiny droplets of juice measuring under 30 µm in diameter. They infused orange and cranberry juice into milk, dark and white chocolate using what is known as a Pickering emulsion. Crucially, the clever chemistry does not take away the chocolatey ‘mouth-feel’ given by the fatty ingredients. This is because the new technique maintains the prized Polymorph V content, the substance in the crystal structure of the fat which gives chocolate its glossy appearance, firm and snappy texture but which also allows it to melt smoothly in the mouth. The final product will taste fruity - but there is the option to use water and a small amount of ascorbic acid (vitamin C) instead of juice to maintain a ‘chocolatey’ taste. Dr Stefan Bon from the Department of Chemistry at the University of Warwick was lead author on the study published in the Journal of Materials Chemistry. He said the research looked at the chemistry behind reducing fat in chocolate, but now it was up to the food industry to use this new technique to develop tasty ways to use it in chocolate. Dr Bon said: “Everyone loves chocolate - but unfortunately we all know that many chocolate bars are high in fat. “However, it’s the fat that gives chocolate all the indulgent sensations that people crave - the silky smooth texture and the way it melts in the mouth but still has a ‘snap’ to it when you break it with your hand. “We’ve found a way to maintain all of those things that make chocolate ‘chocolatey’ but with fruit juice instead of fat. “Our study is just the starting point to healthier chocolate - we’ve established the chemistry behind this new technique but now we’re hoping the food industry will take our method to make tasty, lower-fat chocolate bars.”

We’ve found a way to maintain all of those things that make chocolate ‘chocolatey’ but with fruit juice instead of fat.

The scientists used food-approved ingredients to create a Pickering emulsion, which prevents the small droplets from merging with each other. Moreover, their chocolate formulations in the molten state showed a yield stress which meant that they could prevent the droplets from sinking to the bottom. The new process also prevents the unsightly ‘sugar bloom’ which can appear on chocolate that has been stored for too long. The study, entitled Quiescent Water-in-Oil Pickering Emulsions as a Route toward Healthier Fruit Juice Infused Chocolate Confectionary, was co-authored by Thomas Skelhon, Adam Morgan and Nadia Grossiord at the University of Warwick.

Zebra Chip disease threatening Australian potato industry

FRUIT & VEGETABLES

A potato disease that causes yield losses of up to 50% is threatening the Australian potato industry, AUSVEG claims. The peak industry body for vegetable growers says that the Zebra Chip disease could be introduced into Australia if the federal government approves market access for New Zealand potatoes. If approved, the market access request would allow fresh potatoes to be imported into Australia for processing to produce French fries and potato chips. The Zebra Chip disease reportedly caused over $60 million worth of losses in New Zealand in 2008-09. The Australian potato industry was estimated to be worth $614 million in 2009-10 and represents one of Australian horticulture’s largest crops. AUSVEG is concerned about the impact of the Zebra Chip disease on the Australian industry if the market access request is approved. “The quality and scientific validity of the federal government’s advice on potato importation contains a number of claims which are not scientifically based

and this places the Australian potato industry at risk from this devastating disease,” said AUSVEG CEO Richard Mulcahy. “Placing the livelihood of these Australian potato growers and their families in danger based on import conditions constructed from poorly researched, non-scientific information is simply far too great a risk to take,” Mulcahy said. AUSVEG is urging the government to scrap the proposed importation measures as it claims the disease is not fully understood, even by DAFF Biosecurity. “The draft import conditions report is largely based on a pest risk analysis written in 2009,” Mulcahy said. “This pest risk analysis is severely out of date considering the significant advances made in the last three years of the understanding of this disease and its devastating potential. “The report also fails to consider other potential pathways for the disease into Australia, such as in nursery stock. This is a serious oversight if DAFF Biosecurity is genuinely concerned about protecting our nation from exotic pests and diseases,” Mulcahy said. The disease complex also affects other staple foods such as tomatoes and capsicums and is spread by an insect called the Tomato-Potato Psyllid and through live plant material.

DAFF releases report on imports of fresh ginger from Fiji The Department of Agriculture, Fisheries and Forestry (DAFF) has issued the Provisional Final Import Risk Analysis Report for Fresh Ginger from Fiji, which proposes strict quarantine conditions. “The department’s biosecurity scientists have undertaken a rigorous scientific and evidence-based analysis of the pests and diseases associated with the trade,” said Dr Vanessa Findlay, Chief Plant Protection Officer. “The department has consulted with industry and state governments to ensure the appropriate measures to manage any potential risk associated with importing ginger for processing are in place.” The report recommends that imported ginger must: • be free from soil and trash such as leaf matter • be grown with infield management controls or undergo a post-harvest treatment for burrowing nematode • undergo inspection and certification by the Biosecurity Authority of Fiji to ensure it is free from pests such as yam scale • be inspected and cleared by DAFF “Stakeholder comments submitted during the 60-day comment period were carefully considered and these comments combined with scientific analysis helped inform the final recommendations outlined in the report,” Dr Findlay said. DAFF requests that anyone who believes that the Import Risk Analysis (IRA) process was not properly followed submit a written appeal to the Import Risk Analysis Appeals Panel before 10 September 2012.

Spray-on coating delays banana ripening

Bananas ripen, soften and rot into an unappetising mush, seemingly in the blink of an eye - but a solution may be at hand.

A

t the 244th National Meeting & Exposition of the American Chemical Society, scientists described their efforts to develop a spray-on coating that consumers could use to delay the ripening of bananas. The coating is a so-called ‘hydrogel’, a superabsorbent material like those with many medical and commercial uses, made from chitosan, a substance derived from shrimp and crab shells. Xihong Li, PhD, who presented the report, noted that chitosan is attracting considerable attention in efforts to keep fruits and vegetables fresher longer due to its action in killing bacteria that cause produce to rot, low cost and other properties. Until now, however, it has not been used to slow the ripening of bananas. “We found that by spraying green bananas with a chitosan aerogel, we can keep bananas fresh for up to 12 days,” said Li, who is the study’s leader. “Once bananas begin to mature, they quickly become yellow and soft, and then they rot. We have developed a way to keep bananas green for a longer time and inhibit the rapid ripening that occurs. Such a coating could be used at home by consumers, in supermarkets or during shipment of bananas.” Li explained that bananas, like other fresh fruit and vegetables, are alive and actually ‘breathing’, or respirating. He is with Tianjin University of Science and Technology, Tianjin, China. Like other fresh fruit and vegetables, bananas stay alive after picking. Like people, bananas breathe, or respire, taking in oxygen and releasing carbon dioxide - but

through their skin. The more a banana respires, the quicker it ripens. Unlike many other fruits, the respiration rate in bananas does not slow down, and bananas do not ripen slowly. The banana’s pulp releases a chemical that boosts respiration, and the pulp converts into the sugars that produce that sweet, banana taste. As respiration continues, however, the process speeds up, and bananas become unpleasantly sweet and mushy. Bacteria on the banana skin start to thrive and cause the banana to rot.

Unlike many other fruits, the respiration rate in bananas does not slow down, and bananas do not ripen slowly.

In their study, Li’s team showed that the chitosan hydrogel coating slowed down respiration and killed bacteria that cause rotting, keeping bananas fresh for almost two weeks. But banana lovers should not go bananas over the hydrogel coating just yet. Li’s team is on the trail of a new ingredient for producing the hydrogel that would replace an existing ingredient that would not be used commercially. This study was supported by a National Natural Science Foundation of China Grant and the China Postdoctoral Science Foundation.

Vegetable growers concerned by rising imports “The Australian vegetable industry is now, more than ever, facing fierce competition from overseas markets and the pressure is mounting on growers to reduce their costs and operate on even slimmer profit margins,” said Mulcahy. Mulcahy urged the government to consider measures to help growers combat rising input costs and compete with overseas competition. “While growers and processors here are committed to producing the high-quality products that Australian households have come to expect, if the level of imported products that we are currently seeing increases much further then it will be a grim future for these industries indeed,” Mulcahy said.

Statistics showing that processed vegetable imports have increased dramatically have dismayed Australian vegetable growers. According to the Department of Foreign Affairs and Trade (DFAT) Composition of Trade Australia 2011 statistics, imports of processed fruit and vegetables increased by as much as $119 million. DFAT attributes the increase in part to the high Australian dollar. “These figures demonstrate an alarming trend that is getting worse, year on year,” said AUSVEG CEO Richard Mulcahy. “The volume of processed vegetable imports in this country has reached worrying heights and measures must be taken immediately to ensure that Australian vegetable producers are provided with a proper level playing field.” Continued high imports could jeopardise the viability of Australia growers, Mulcahy said.

that measures flow from 0.07 to 305 nmps with an accuracy of ±0.75% of reading, ±0.5% of full scale. Designed for rugged industrial processes and plants, the meters include service up to 454°C and are available with both integral and remote 300 m electronics versions. They are agency-approved for hazardous environments, including the entire instrument, the transmitter and the rugged, NEMA 4X/IP67-rated closure. The meters are available with 4-20 mA analog, frequency/pulse, alarm relays and additional digital bus communications including Fieldbus, Profibus and Modbus. They are adaptable with a plug-in card replacement that can be changed out by plant technicians in the field. The meters store up to five calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases and obtain up to 1000:1 turndown. The ST100 Series has obtained full certification from the HART Foundation for its hardware and DD files. The ST100 offers three different types of flow sensor: the fast-response FPC-style is suitable for compressed air and clean gas applications; the fast-response, general-purpose, FP style is the sensor used with FCI’s VeriCal in-situ calibration option; and the unshrouded S-style is suitable for wet or dirty gases, or erratic flows.

Sensor switch for fill-level detection Baumer claims its LBFS switch is a reliable alternative to vibratory level switches. The LBFS sensor can detect the levels of viscous or dry materials and can be fitted on tanks or pipes in any desired position. The sensor is insensitive to flow, turbulence, bubbles, foaming and suspended solids and its compact, smooth sensor head resists media adhesion, even with sticky media. The company says the sensor’s short response time enables rapid fill-level detection and accurate, reliable fill-level compliance. The level switch can detect media levels in tanks, vessels and pipes. It can also be used for overflow prevention, pump protection against dry running and media separation with oil/water mixtures. It is suitable for a range of application areas, including domestic water, wastewater, HVAC filters, hydraulic systems, oil and gas, bioenergy,

TESTING

wood pellets, grain mills, rail transport and pump systems. The sensor is housed in a compact, sturdy and corrosion-resistant stainless steel enclosure. It can be installed easily using Teflon tape sealing. Configuration is facilitated by the PC-based FlexProgrammer 9701. A short response time of 0.2 s means the level switch operates reliably even with fast filling processes. The device has a rated operating temperature range of -40 to +115°C. The LBFS operates on the frequency sweep principle using a high-frequency signal emitted by the sensor which experiences a phase shift in the sensed medium. When this sensor encounters a medium having a dielectric constant outside the defined range, an electronic signal is triggered. The sensor’s good sensitivity over a large measuring range for dielectric constants from 1.5 to over 100 enables limit detection with a range of powders, granulates and liquids, and even difficult substances such as polyamide granulates and paper.

Insertion electromagnetic flow meter Bürkert’s Type 8045 insertion electromagnetic flow meter has been re-engineered. The meter now has a cut-off feature which is claimed to optimise use in low-flow applications. This function allows the operator to set a lower limit, under which the measurement value is set as zero. This parameter feeds through to display, totalisers, outputs and downstream process conditions. A menu-configured digital input has also been added to the meter, allowing control system initiated reset of totalising functions, hold mode go-to, zero-point calibration and other functions. This has been added to facilitate remote control capabilities via site control systems. An adjustable backlit display for reading and programming in dim conditions has been added. The meter has integrated diagnostics to support local operation, with a simple and conspicuous green/orange/red LED status indication. The 8045 flow meter is an all-purpose unit with no moving parts, making it suitable for a range of processes, including those with particulate contamination. Processes must be conductive, measuring >20 µs and up to 400 mm process pipe diameter. Insertion mag flow meters insert a sensor finger with integrated electronics into the process flow, rather than replacing a portion of the pipework as full bore mag flow meters do. Insertion mag flow meter types are claimed to be advantageous where the accuracy (~0.5%) of a full bore mag flow meter is not required and ~2% accuracy will suffice. The flow meter is claimed to be easier to install and service than a full bore mag flow meter for this type of application.

AUTOMATION, SENSING & ROBOTICS

Food and water safety provide new challenges for today’s sensors Sensors that work flawlessly in laboratory settings may stumble when it comes to performing in real-world conditions, according to researchers at the US Department of Energy’s Oak Ridge National Laboratory.

T

hese shortcomings are important as they relate to safeguarding food and water supplies, said Ali Passian, lead author of a Perspective paper published in ACS Nano. In their paper, ‘Critical issues in sensor science to aid food and water safety’, the researchers observe that while sensors are becoming increasingly sophisticated, little or no field testing has been reported. “Although sensor researchers are keenly aware of the various issues challenging their particular technologies, outsiders may perceive an overestimated level of performance or, in certain cases, the availability of ‘uber-sensors’,” the researchers wrote. Co-authors are Rubye Farahi and Laurene Tetard of ORNL and Thomas Thundat of the University of Alberta. Salmonella, E. coli, pesticides and mercury are among key targets for sensors, so a clear public understanding of their capabilities - and limits - is essential, particularly because food and water make for highly complex chemical and biological environments, Passian said. “Given the current physics of sensors, these hazards pose especially difficult challenges that will require further research and successful demonstration,” Passian said.

lenges for which nanoscience may provide new solutions,” Passian said. Nanosensors take on a variety of shapes, sizes and architecture. In some devices, nanoparticles (gold, silicon, magnetic composites or polymers) or nanowires (gold, polymers or composites) that react in the presence of the targeted substance are incorporated into the instrument. Advantages of nanosized particles in sensors include low cost, high surface-to-volume ratios, high sensitivity, unique optical and electrical properties and fast response, but these are intertwined with offsetting traits. A number of issues are inherent in the design and operation of nanosensors. For example, the fact the nanosized particles are so tiny can reduce the probability of interactions with the substance to be measured. Consequently, sensor developers are burdened with reaching a balance between reliability, cost effectiveness, portability, robustness and mass producibility. Passian and the co-authors also stressed the need for a real-time flow of information to allow for quicker response time to assess risk, damage and notification of the affected populations. Ultimately, while many quality control measures are in place, requirements will continue to be refined. “With the ever-growing global population and unpredictable natural phenomena such as earthquakes, early development of better sensor technology for food and water safety is vitally important,” Passian said.

Compact pressure sensor with NPN circuit Suitable for pneumatic applications in robotics and handling, ifm efector’s PQ compact pressure sensor series is now equipped with NPN circuit. Using a sealed measuring cell, these sensors detect the pressure in the vacuum and overpressure range. The piezoresistive silicon cell measures, depending on the selected unit, between -1 and 10 bar or -1 and 1 bar. Due to the special sealing of the measuring cell, the pressure sensors are insensitive to liquids such as condensed water and deposits that might occur in the system. The sensors have good overload resistance and an accuracy of < ±0.5%. The sensors’ slanted 4-digit display can be electronically rotated by 180° and read at a distance, from the front or from above. The display colour is selectable, with a green display colour for the acceptable range and red when the switching point is exceeded or not reached. Two programmable switching outputs or one switching output and one diagnostic output provide flexible use. The sensors are easy to install by means of integrated mounting holes; a range of accessories is available for this. The NPN circuit makes the unit suitable for exportation. ifm efector pty ltd Contact info and more items like this at wf.net.au/Q115

Slippery coating evicts biofilms A new slippery technology that has been shown to prevent more than 99% of bacterial slime from forming on surfaces may prove a boon in food processors’ battles to keep surfaces hygienic.

B

iofilms stick to just about everything, from stainless steel food preparation equipment, copper pipes and steel ship hulls to glass catheters. The slimy coatings are more than just a nuisance, resulting in decreased energy efficiency, contamination of water and food supplies, and - especially in medical settings - persistent infections. Even cavities in teeth are the unwelcome result of bacterial colonies. But now a team of Harvard scientists has developed a slick way to prevent the troublesome bacterial communities from ever forming on a surface. In a study published in the Proceedings of the National Academy of Sciences (PNAS), lead co-authors Joanna Aizenberg, Alexander Epstein and Tak-Sing Wong coated solid surfaces with an immobilised liquid film to trick the bacteria into thinking they had nowhere to attach and grow. “People have tried all sorts of things to deter biofilm buildup - textured surfaces, chemical coatings and antibiotics, for example,” says Aizenberg, Amy Smith Berylson Professor of Materials Science at the Harvard School of Engineering and Applied Sciences (SEAS) and a Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard. “In all those cases, the solutions are short-lived at best. The surface treatments wear off, become covered with dirt or the bacteria even deposit their own coatings on top of the coating intended to prevent them. In the end,

bacteria manage to settle and grow on just about any solid surface we can come up with.” Taking a completely different approach, the researchers used their recently developed technology, dubbed SLIPS (slippery-liquid-infused porous surfaces), to effectively create a hybrid surface that is smooth and slippery due to the liquid layer that is immobilised on it. First described in the journal Nature last year, the superslippery surfaces have been shown to repel both water- and oil-based liquids and even prevent ice or frost from forming. “By creating a liquid-infused structured surface, we deprive bacteria of the static interface they need to get a grip and grow together into biofilms,” says Epstein, a recent PhD graduate who worked in Aizenberg’s lab at the time of the study. “In essence, we turned a once bacteria-friendly solid surface into a liquid one. As a result, biofilms cannot cling to the material, and even if they do form, they easily ‘slip’ off under mild flow conditions,” adds Wong, a researcher at SEAS and a Croucher Foundation Postdoctoral Fellow at the Wyss Institute. Aizenberg and her collaborators reported that SLIPS reduced the formation of three of the most notorious, diseasecausing biofilms - Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus by 96-99% - over a 7-day period. The technology works in both a static environment and under flow, or natural conditions, making it particularly

suitable for coating implanted medical devices that interact with bodily fluids. The coated surfaces can also combat bacterial growth in environments with extreme pH levels, intense ultraviolet light and high salinity. SLIPS is also non-toxic, readily scalable and - most importantly - self-cleaning, needing nothing more than gravity or a gentle flow of liquid to stay unsoiled. As previously demonstrated with a wide variety of liquids and solids, including blood, oil and ice, everything seems to slip off surfaces treated with the technology. To date, this may be the first successful test of a nontoxic synthetic surface that can almost completely prevent the formation of biofilms over an extended period of time.

The approach may find application in medical, industrial and consumer products and settings. In future studies, the researchers aim to better understand the mechanisms involved in preventing biofilms. In particular, they are interested in whether any bacteria transiently attach to the interface and then slip off, if they just float above the surface or if any individuals can remain loosely attached. “Biofilms have been amazing at outsmarting us. And even when we can attack them, we often make the situation worse with toxins or chemicals. With some very cool, nature-inspired design tricks, we are excited about the possibility that biofilms may have finally met their match,” concludes Aizenberg.

Fresh-cut produce dryer Key Technology has redesigned its Auto Dryer, adjusting the controls, motor and structure. Like the original dryer, it removes surface water from fresh-cut produce and vegetables, but it also enables continuous line flow. The dryer achieves fully automated, uninterrupted loading and unloading. Compared to batch drying, the dryer is claimed to increase throughput in smaller floor space while reducing labour and improving worker safety and sanitation. The dryer can handle 500-1360 kg of product per hour per drum, meaning the fourdrum model can handle up to 2000 kg/h when drying lightweight products and up to 5443 kg/h when handling heavier products. The dryer may reduce product damage and maximise drying efficiency by loading a constant flow of product into dryer drums via a spiral layering method that eliminates product slug. With centrifugal pressure, the unique spiral layering achieves uniform drying while reducing wear on mechanical parts. The redesigned hood system enables access to the drum for cleaning. The stainless steel dryer is designed to food safety standards to minimise cracks and crevices that can harbour bacteria. The control system monitors the condition of the drum and automatically adjusts the spin speed if an out-of-balance condition is detected, reducing wear. Key offers an optional package with the dryer that includes a dual-level storage belt, dewatering feed shaker and discharge belt conveyor. Addressing fresh-cut processors’ need to relocate their production lines, the company designed the dryer so it can be moved with a forklift and the configuration of the system can be modified in the field.

Third-party audits and food safety

Part II: Harmonisation of standards and a process-based approach Globally, food has never been safer. Driven by food scares and a heightened focus on risk mitigation, there has been a move by governments, manufacturers and retailers to join forces and put independent third-party assessment and certification at the heart of food safety.

T

oday’s global food supply chain is exponentially more complex than it was 50 years ago and yet, the food products that are grown, processed, packaged and sold in all corners of the globe are significantly safer than they have ever been. That these apparently conflicting facts can simultaneously exist is largely an output of the collaboration and transparency that is being led by the most influential food manufacturers and retailers. Two particular areas have worked together to bring this about; the first of these is the harmonisation of standards. Harmonised, robust food safety management system standards and schemes have brought increased transparency and best practice sharing across sectors and geographies. The Global Food Safety Initiative (GFSI) was formed in 2000 by leading global retailers and manufacturers specifically to address food safety issues and the lack of harmonisation in food safety standards and schemes. Together with the International Organization for Standardization (ISO), they have driven the move towards a manageable set of globally accepted management systems-based standards and schemes. This move has benefited suppliers as well, driving down costs by significantly reducing the number of audits they have to undergo and ensuring the audits that take place are addressing potential risks. In 2004, ISO 22000, the first global food safety management system, was issued. FSSC 22000, a complete food safety certification scheme, was developed in 2010 to meet the needs of food supply chain stakeholders. FSSC 22000 is owned by the Foundation for Food Safety Certification, an independent, not-for-profit organisation. January 2012 marked the 1000th FSSC 22000 certificate being issued. 64

September/October 2012

Through the harmonisation of standards, the market at large could now easily benchmark against international standards and GFSI-recognised schemes such as ISO 22000 and FSSC 22000. As Mark Overland, Director for Global Certification at Cargill, commented. “We are rolling out FSSC 22000 to over 1000 plants in 67 countries. Having the same level of food safety execution at every plant is an expectation from our customers.” Along with the Foundation for Food Safety, both the GFSI and ISO have to be applauded as very important initiatives. The GFSI’s work on harmonising standards and schemes has resulted in there now being only 12 approved standards from a starting point of 100, which is clearly a significant achievement and we may expect the number will decrease in the future.

Process-based approach The second area is that of an evolving assessment approach, one driven by the strategic needs of clients and the technical expertise of auditors, which has led to a transition in the role of assessments and auditors. The single-snapshotin-time checklist style is fading into the history books and being replaced with dynamic process-based management systems audits. Delivered through auditor competency and sector specific expertise, these audits focus on the systems and processes that strategically underpin organisations and their supply chains, and it is this holistic approach that is gaining a foothold amongst retailers, manufacturers and suppliers.

afford any food safety issues. “FSSC 22000 delivers a whole new approach to risk management and quality assurance,” explains Mr Speelmans, Safety Health Environmental Quality Manager. “Through LRQA Business Assurance, the whole network of interacting processes is assessed and monitored, thus providing greater assurance to both internal and external stakeholders and protecting our brand reputation.” While FSSC may have come in for some criticism for being costly, the cost savings in real terms are potentially huge and the value of harmonisation is clearly supported by Wrigley, a subsidiary of Mars, Incorporated, which stated that, “Wrigley’s North American factories saw on average a 25-50% reduction of audits by retailers with the adoption of FSSC 22000.” In direct opposition to the holistic approach embedded into FSSC 22000, the certification body that undertook the audit at Jensen Farms which lays at the heart of the Listeria outbreak commented that “the audits are intended to assess whether the client’s operations are in compliance with current baseline industry standards - not to improve those standards or push a client towards best practices”. This is a crucial difference with the management system audit approach where improvement and best practices are a significant part of the process. Part III will conclude this article.

Less work for better returns: macadamia sorting system is an all-round cracker PROCESSING

Better returns, reduced loss, improved product quality and a high throughput rate: the new dehusking and sorting system at the Macadamia Processing Company’s (MPC’s) Alphadale facility has been a success for growers and processors alike. “Since the 1990s, the macadamia industry has approached quality by applying reject penalties in payment systems,” said MPC’s General Manager, Steve Lee. “This has caused farmers to spend many hours sorting and resorting macadamias on their farm before delivery to the factory. It’s a costly process for growers and we felt there had to be a better way.” “So we set about developing a system that removes the need for farmers to sort their own nuts, increases yield per hectare, reduces potential quality losses and maintains the value of the macadamias.” “We also wanted to centralise the task of dehusking and sorting nuts without slowing down the current rates of receiving and processing,” added Kevin Quinlan, Supply Chain Manager - NIS (Nut-In-Shell) at MPC. “This meant we needed machinery with high throughput rate that was highly efficient and could be operated with minimal supervision by staff.” MPC wanted a system that was at the cutting edge of macadamia processing with new cleaning technology, combined with the latest NIS and kernel colour sorting machines. It had to be efficient and able to handle high volumes while handling the macadamias in such a way as to minimise damage. “There were some challenges because this is a first for the industry,” Quinlan said. “It was not just a matter of installing existing equipment.” MPC devised a solution based on a mix of standard machinery and specifically designed machinery to meet its needs. “Some of the new machinery is available commercially and we used that where appropriate,” Quinlan said. “However, we had to design some of our own equipment as there is not much macadamia-specific machinery available commercially anywhere in the world. Some of the standard equipment had to be modified in terms of its operating parameters, both physical and programming, especially for the new colour sorters.” All design work was carried out in-house, with MPC’s engineering staff drawing on past experience to design and manufacture a system that would suit the company’s needs. In researching the new system, MPC found that by reducing the interval between nut fall and delivery to the factory, growers’ returns would be improved as quality would be maintained. Not having to store nuts for sorting reduces the possibility of storage defects like discolouration, mould and internal discolouration (brown centres). The new cleaning machinery removes trash, rock and rejects from consignments before they are sampled and placed in silos. This service is provided free of charge to MPC’s growers. When combined with the kernel colour sorters, MPC is now able to remove all rejects that were formerly removed by on-farm hand sorting. For growers requiring full dehusking, MPC has worked with Alstonville’s House With No Steps to develop a system that offers full dehusking at a cost of 6 cents per kilogram of input weight. “The new system is allowing us to operate at our same receiving and processing speeds,” Quinlan said. “For our growers, they are experiencing a reduced workload and considerable cost savings, often up to 10 cents per kilogram. “From our perspective we are seeing good quality nuts reaching the factory and our processing speed has been maintained. Most importantly, consumers will get to taste the higher quality kernel produced from our changes and we believe this will see increased demand for our products,” Quinlan said. “We see the new system as a win for both the grower and the consumer,” Lee added.

Lower pasteurisation temperature may limit spore germination Even if milk has been pasteurised to kill off microbes that can cause food spoilage and disease, certain bacterial strains can survive the heat shock as spores and cause milk to curdle in storage. Now it seems that higher pasteurisation temperatures may aid spore germination.

R

esearchers in the Milk Quality Improvement Program at Cornell’s College of Agriculture and Life Sciences have identified the predominant spore-forming bacteria in milk and their unique enzyme activity, knowledge that can now be used to protect the quality and shelf life of dairy products. “Control of food spoilage is critical in a world that needs to feed 7 billion people,” said Martin Wiedmann, food science professor and study co-author. “Approximately 25% of postharvest food is spoiled by microbes before it is consumed.” The study, published earlier this year in Applied Environmental Microbiology by the lab of Wiedmann and Kathryn Boor, the Ronald P Lynch Dean of the College of Agriculture and Life Sciences, identified the predominant strains of spore-forming bacteria, which can foul milk and other food products. The culprits, Paenibacillus bacteria, are ubiquitous in nature and cause off-flavours in a variety of foods and curdling in dairy products. As spores, the bacteria can survive in dormant form for years despite the best practices in cleaning, processing and packaging. In fact, the bacteria may be uniquely adapted to overcome the twin tactics of dairy protection: pasteurisation followed by refrigeration. According to co-author and research support specialist Nicole Martin, the spores are not only resistant to heat, the small jolt of heat during pasteurisation may actually stimulate them to germinate. Some can reproduce in refrigerated dairy products at temperatures that would stymy other types of bacteria. “We studied 1288 bacterial isolates in raw milk, pasteurised milk and the dairy farm environment; however, only a handful 68

September/October 2012

of strains accounted for 80% of the spore-formers present,” said Wiedmann. “They grow well in milk - and possibly other foods - at temperatures as low as 6°C, and we can identify Paenibacillus because of their uniquely high galactosidase enzyme activity at 32°C.” They also investigated how pasteurisation affects the presence of such bacteria. In the US, concerns about food safety have prompted many dairy processors to increase pasteurisation temperatures above the 72°C minimum set by the government. Anecdotal reports, however, suggested this practice actually led to more spoilage once the products were refrigerated. Tallying bacterial numbers throughout the refrigerated shelf life of milk pasteurised at two different temperatures - 76°C and 79.5°C - the Wiedmann-Boor lab found that lowering the temperature significantly reduced bacterial growth during refrigerated storage, especially by 21 days after pasteurisation. The findings are already being applied in the field. The Wiedmann-Boor Lab was enlisted by Upstate Niagara, a cooperative of more than 360 dairy farm families throughout western New York, to further improve the quality of its award-winning milk by assessing milk samples for spore-formers. Data on samples that contained spore-forming bacteria are now being analysed using DNA fingerprinting to identify the types of organisms present and where they might have come from. Martin said she hopes the collaborative project will become a model for how to approach spore-forming bacteria in individual dairy processing plants.

Safety barrier reels ReCoila has designed a specialised reel that can alternate between being a buffer and a thoroughfare. The BAR Series reels provide a solution for areas that are designated as both thoroughfare and restricted access, such as warehouse roller doors where deliveries come in and stock goes out, but visitors need to be made aware of ‘No Entry’ rules. Traditionally for this type of application, businesses have used traffic cones, bollards or signs, but when access is required multiple times a day, bollards and similar barrier methods can be cumbersome and are sometimes not put back in place and, as is the case with wall signage, are some-

Food-grade lubricant Ultra FG, the Ingersoll Rand food-grade lubricant, has an extended life which optimises rotary screw compressor performance by reducing the time to service components and increasing maintenance intervals. Ultra FG lubricates moving parts, dissipates heat, resists degradation from food and chemicals, and does not react with sealing materials, plastics and elastomers. Traditionally, food-grade lubricants can be used for approximately 1000 h before needing to be replaced. Ultra FG has an operational life of approximately 6000 h. Its temperature stability prevents formation of damaging abrasive deposits and, when

PROCESSING

mixed with water, the lubricant does not break down into harmful components such as acids and alcohols, which can varnish components and lead to premature failure. The lubricant has an advanced synthetic composition that incorporates advanced additive technologies that include antiwear agents, rust inhibitors and antioxidants. The lubricant can prevent build-up of particulates in critical areas of a compressor by promoting the breakdown of some substances and by absorbing others so they can be carried to filters and separators for removal. To minimise health risks to consumers, Ultra FG lubricant exceeds industry requirements for incidental food contact by meeting the requirements of FDA Title 21 CFR 178.3570 regulations. It is also H-1 compliant for the US Department of Agriculture and has been kosher and parve certified. The lubricant also contains an antimicrobial agent that not only inhibits growth of any contaminations but also provides good neutralisation, protecting the lubricant from spreading bacteria or mould spores.

Upscaling the production of ethnic ready meals

such as continuous spiral ovens and mini flame grills provide a cost-effective bridge for producers of ethnic ready meals to meet skyrocketing demands.

T

he popularity of ‘food’ shows on TV and global population migration combined with the trend towards higher quality, healthy packaged foods have resulted in amazing growth in ready-to-eat ethnic foods. Whether it is fresh salsa, hummus, gyro meat, Chinese stir fry or tofu, many ready-to-eat ethnic foods that were once considered specialty items found in the ethnic food isle of a grocery store are now mainstream offerings. The growth and interest in these types of foods, in fact, has been so phenomenal in the last decade that many of these products no longer seem ‘ethnic’ at all. Furthermore, this trend shows no signs of slowing any time soon. According to consumer market research firm Mintel, the sales of ethnic foods in the US will grow by another 20% in the next couple of years, with diversity increasing substantially from earlier in the decade when Mexican/Hispanic were dominant with over 60% share of the ethic food sales. 78

September/October 2012

More recently, Asian and Indian foods grew by 11 and 35% respectively. Other foods of ethnic origin, such as hummus and tofu, have grown by hundreds of percent in popularity around the globe. To meet the dramatically increasing demand, many smaller, specialty food processors are increasing the variety and type of ready-made ethnic and global fare offerings. Hummus, for example, is now offered in organic and non-organic varieties such as artichoke, eggplant, garlic, roasted red pepper and even chocolate. Yet, the challenge to smaller food processors is how to expand production to meet the explosive demand for these products. Where modest food processing equipment was adequate even five years ago, many now must find cost-effective equipment that can serve as a bridge to meet higher volume requirements while also retaining the authenticity and quality of the dishes they produce.

used directly inline with a continuous oven. Adjustable flame burners allow for the enhancement of flavour, colour and yield. The spiral ovens, available in full-size, mini and micro sizes, are recommended for steaming, roasting, broiling and baking, as well as post pasteurisation, and can be coupled with a chiller and loading systems to suit processing needs. Aronson adds that one of the other benefits of the spiral oven is its compact size, which translates to high-volume output in a relatively small space. Because the oven spirals in a vertical direction, the footprint can be quite small.

Spiralling kabob sales When Exotic Foodline LLC (Richardson, TX) began operations in 2002, the market for its frozen Middle Eastern, Indian and Pakistani dishes was less than CEO Mansur Kaiser had anticipated. “It took five or six years before the market for these foods began picking up rapidly, and supermarkets were getting interested in our line,” Kaiser explains. “Now, the North American market for these ethnic foods is so strong that I believe it is going to be similar to that of England, where there has been a high demand for years.” Kaiser adds that with strong sales in the US now, he looks forward to exporting his line into Canada and the Middle East soon, where his types of ethnic dishes promise to be popular. Kaiser says Exotic Foodline is also expanding its selection of frozen foods. “Our biggest sellers are the grilled barbecue items, particularly kabobs (marketed under the brand name Colonel Kababz). But we also now offer a selection of snack items such as tandoori chicken wings and samosas, plus several new entrees such as chicken tikka masala and biryani,” explains Kaiser. Kaiser feels that now that frozen Indian, Pakistani and Middle Eastern foods have caught on, he needs to address the requirements for mass production, which far exceed the capacity of the existing grilling system that he customised in-house. “We are now looking at Unitherm cooking systems equipment to help us produce the higher volumes of foods that we need in the future,” says Kaiser. Kaiser adds that one of the unique attractions of Unitherm equipment is the availability of compact cooking systems that have powerful features, yet small footprints. In addition to saving on space, some systems can also keep capital investments lower. “If I need from 150-250 kg/h of production, I don’t want to have to buy equipment that handles 2500 kg/h,” Kaiser explains. “That would be much more expensive and take up too much space.” “Also, we offer many BBQ items that can’t be prepared on just any type of equipment. So we tested our product on a Unitherm spiral oven and it came out just like it does on the open fire grill. It was very good quality. So that kind of cooking system could be a good bridge for us to produce higher volumes efficiently,” adds Kaiser.

Economical expansion The explosive growth of ethnic and global foods has also created a need for Panache! Creative Cuisine to meet high volume opportunities without requiring major capital outlays, according to company president Jonathan Stack. “We are launching a new line of Street Foodz that will span our six core categories (sandwiches, salads, entrees, snacks and sides, breakfast and desserts) with ethnic flavour profiles. We plan to incorporate Indian, Asian, Mediterranean, European, Cuban, Latin American and other styles of foods into that line, which will require considerably higher volumes.”

The food processing equipment issue was familiar to Jack Aronson, CEO of Garden Fresh Gourmet brand foods (Ferndale, MI), the producer of a broad line of handcrafted, all-natural salsa, guacamole, tortilla chips, hummus and other ethnic foods. Starting out as a husband-and-wife team that began making a fresh blend of artichoke salsa on a small table in the back of their restaurant, Aronson’s company has grown from $4 million in sales in 2004 to over $100 million this year. “We’re experiencing a lot of growth in ethnic foods.” Aronson explains. “So there is an inherent need for those products to be fresh and natural, and to use authentic ingredients. That’s one of the reasons why ethnic foods like salsa, guacamole and hummus are healthy.” His passion for creating authentic traditional foods led Aronson to questions about what kind of food processing equipment would enable Garden Fresh to meet skyrocketing demands while still retaining the traditional appearance, taste and texture of the foods that were previously handcrafted in a small kitchen. In addition to increases in the varieties and volumes of salsas, the company wanted to keep up with the booming popularity of hummus throughout much of the world, because much of Garden Fresh’s growth was due to the rapid growth of that product. At the same time, Garden Fresh was looking to expand its product line to include Lebanese kofta, cubano peppers and possibly other ethnic dishes, so flexibility of equipment was also important. “With an eye to the present and future, we looked at a lot of different types of equipment,” Aronson says. “Then a business associate mentioned that Unitherm Food Systems makes a cutting-edge line of cooking and chilling equipment that might be suitable for our company.” The line includes equipment that is compact yet surprisingly productive and affordable, such as mini flame grills and continuous mini spiral ovens and chillers. Another important thing was Unitherm had Garden Fresh ship its original product to the factory kitchen where they tested the products using different types of cooking and chilling equipment, Aronson says. “They recommended specific systems as well as parameters such as cook times and temperatures,” he says. Aronson says the equipment he bought brought him up to speed in product volume while also enabling him to retain the quality that is essential to Garden Fresh foods. It also allows him the flexibility to handle his growing assortment of products. “When I do things on a large scale, for example, such as eggplant for my hummus, it goes through the fire-roaster in about 45 seconds,” explains Aronson. “If it is a thick product, like carrots, it also has to be cooked on the inside. So, we put the carrots through our fire roaster to get the caramelisation that enhances appearance, and then we bake them in the spiral oven, which finishes the cooking process.” Garden Fresh also uses the new fire roaster to cook peppers that are used in several dishes, including salsas. “We used to roast peppers on a gas grill, which was a very painstaking method,” Aronson says. “But when we got a large account, it was obvious that we needed a new approach. Now, using a spiral oven, I can do 500 kg of vegetables on the spiral oven in the time it took me to do 10 kg on a gas oven.” Unitherm’s flame griller and mini flame griller systems function as standalone cookers or as searing ovens that may be

Space saving designs make incorporating equipment into production areas simpler.

Garden Fresh tested different types of Unitherm equipment to ascertain its suitability for their products.

Stack says that his company has been growing at a doubledigit rate for the past five or six years, partly due to the success of Panache’s kosher operation Bubbie’s Gourmet. “We’ve been studying this growth opportunity for several years,” Stack says. “Unitherm has given us valuable help in understanding our choices of affordable equipment that can allow us to produce ready foods in much higher volumes and still retain or even enhance our quality standards. Also, they have some very innovative designs and that allows us to incorporate more equipment in a limited space along with the ability

Dimples the solution to energy efficiency PROCESSING

Leading up to the 1 July deadline and impending introduction of the carbon tax, Teralba Industries was approached by a number of food processing plants to find a solution that would help them reduce their carbon footprint and energy costs. Teralba worked with each business closely to calculate the energy savings they could expect while illustrating the reduced impact on the environment that Teralba’s solutions delivered. One such plant, based in Tasmania, had a consistent outflow of 85°C dirty hot waste water from its process lines and an inlet water temperature of approximately 15°C which had to be heated to 90°C, consuming a total of 365 kW/h. Calculations suggested that recovery of waste heat would avoid the consumption of 647 t coal per annum, saving approximately $84,000 per year in fuel costs. Carbon dioxide emissions of 1780 t per annum would also be avoided,

further increasing the possible savings to $128,000 per annum. The end result was a Dimpleflo heat exchanger designed by Teralba Industries that met the client’s specific needs, saved money in energy costs and reduced the plant’s overall carbon footprint. Utilising field testing and analysis data, Teralba Industries says it can design and install Dimpleflo solutions that successfully save businesses money on a daily basis.

CostaExchange, part of the Costa Group, is a major grower, packer, marketer, distributor and exporter of fresh fruit and vegetables. The business has an economic presence in more than 30 regional and rural communities across Australia, including farms, packing facilities and distribution centres. Identifying a need to measure and manage its quality performance across multiple product categories, CostaExchange selected Muddy Boots’ Greenlight Quality Control to improve visibility and pinpoint areas where improvements are needed. Muddy Boots says its award-winning Greenlight Quality Control ensures consistency in measuring product quality attributes. Its mobile technology software captures and processes information at the point of input, enabling businesses to identify problem areas and collaborate with suppliers to deliver improvements. Using Greenlight gives increased transparency and a wider sharing of data, giving businesses a clearer view of site, supplier and product performance along the chain. “Quality excellence is a core pillar of the Costa business strategy, fundamental to this is the ability to measure and manage our quality performance across multiple product categories, across a diverse supply base,” said Brett Heather, Group Technical & Alliance Manager at CostaExchange. “The deployment of the Muddy Boots Greenlight system into our business gives us the visibility (by trending performance over time) to highlight areas where improvements are needed, be that product temperature, size, weight, aesthetics and so on. “With improved quality management, through the utilisation of Greenlight QC, Costa sees significant benefits flowing, with improved efficiencies, reduced rejections, enhanced reputation and a stronger bottom line performance,” said Heather.

Exair claims the nozzle has a force more than eight times that of standard air nozzles, making it suitable for blowing heavy materials and in situations where the nozzle can’t be mounted close to the target surface.

The aerodynamic design directs compressed air to a single point of convergence, delivering a concentrated stream of high-velocity airflow. It also meets OSHA standard 29 CFR 1910.242(b) as the compressed air is ejected from holes that can’t be blocked. At 80 psig, the air consumption is 135 scfm and the sound level is 99 dBA, meeting the OSHA standard for 2 hours of use per day without hearing protection. The nozzle has a 1½″ (38 mm) hex body for installation using a standard wrench or socket.

Combating antimicrobial resistance Since the mid-1990s, Denmark has reduced animal consumption of antimicrobial agents by 60% without reducing its agricultural output. Bearing in mind that the global consumption of antimicrobial agents for animals is almost twice the size of human consumption, Denmark’s efforts are a shining light in the global struggle against antimicrobial resistance.

D

enmark was the first country to ban the use of antimicrobial agents as growth promoters on a scientific basis and to establish a national surveillance. The National Food Institute was involved from the outset and has participated in the surveillance of antimicrobial agent consumption and resistance since the mid-90s. In a comment in the journal Nature, Professor Frank Møller Aarestrup, the National Food Institute, Technical University of Denmark, gave his explanation of the success of the Danish efforts.

Cross-sector collaboration “There are three secrets to the Danish success. Since 1995, we have had a national surveillance program, DANMAP, which enables us to continually monitor changes in resistance and document any problems. The 1990s saw political willingness to introduce regulations of the consumption of antimicrobial agents. And there was and still is cross-sector collaboration between farmers, the food industry, researchers and authorities,” said Professor Frank Møller Aarestrup. One of the key steps was the ban on growth promoters, but an essential element is also the Danish surveillance system which documents resistance developments and is able to propose solutions. Each year, the DANMAP surveillance program monitors the consumption of antimicrobial agents - from farm to table to hospital bed - and investigates the incidence of antimicrobial resistance in animals, food and humans. The program is a joint initiative of the National Food Institute, Statens Serum Institut and the National Veterinary Institute, Technical University of Denmark. The DANMAP program was the first of its kind in the world but has now been emulated in many countries. In some coun86

September/October 2012

tries, data are not available from all animal species and the programs do not integrate data from animals and humans in the same way as in Denmark. “All countries that wish to limit their consumption of antimicrobial agents for livestock could learn from the Danish experiences. It only takes some adaptation to local conditions, and we have evidence to show that reducing the consumption of antimicrobial agents prevents the incidence of resistant bacteria. One very effective initiative is that Denmark introduced a ban on veterinarians profiting from writing prescriptions for antimicrobial agents. The consumption of therapeutic antimicrobial agents dropped by almost 30% in 1995, and in Denmark the ban has not resulted in falling agricultural productivity,” says Professor Frank Møller Aarestrup.

Voluntary stop and ‘Yellow Card’ working In July 2010, the Danish Veterinary and Food Administration introduced the so-called ‘Yellow Card’ scheme aimed at reducing the increasing antimicrobial consumption. At the same time, Danish agriculture introduced a voluntary ban on one of the antimicrobial agents, cephalosporin, which is essential for treating humans. The initiatives helped reduce antimicrobial consumption by almost 25% over two years and consumption of cephalosporins decreased by almost 49% in 2010 for pigs. “It is indeed positive to see that both the total consumption and the consumption of cephalosporins have dropped. Resistance to cephalosporins is a rapidly increasing problem in both humans and animals. It is therefore important to maintain the positive development,” says Frank Møller Aarestrup.

Exponential growth in the use of bulk bags has spawned an entire manufacturing segment dedicated to producing specialised equipment that not only fills and discharges bulk bags, but offers various degrees of automation and integrates filling and unloading operations with upstream and downstream equipment.

A

s the number of bag filling equipment options increases, so should the ability of the specifier to evaluate standalone equipment and integrated systems against current and anticipated needs. This article addresses the â&#x20AC;&#x2DC;fillerâ&#x20AC;&#x2122; half of the bulk bag handling equation, offering the six most important parameters to consider when satisfying any individual bulk bag filling requirement with top efficiency and cost-effectiveness.

1. Anticipate maximum capacity The difficult but critical question: how many bulk bags will you need to fill per week during the useful life of your next bulk bag filler? With few exceptions, buying a more costly filler with higher capacity than you now need will be less costly than replacing a filler you outgrow, unless that filler can be retrofitted with performance enhancements at a later date. Capacity requirements run the gamut, from one bag per week to 20 bags per hour. Where your volume falls should, in part, influence your decision to specify a manual, semiautomated or fully automated machine. Generally speaking, the more manual the filling operation, the more output is subject to variation. When gauging the capacity and payback of manual equipment against automated equipment, you need to determine the average pace at which operators can attach, detach and cinch bag spouts, remove filled bags, load pallets and conduct all other filler-related operations. When estimating the time allocated to these manual functions, it is advisable to anticipate a pace that an operator can realistically maintain throughout an entire shift while avoiding fatigue or injury. For the lowest volume applications, a basic manually operated filler will maximise your return on investment. Choose a filler

design that affords unobstructed access to the bag spout and loops, facilitating rapid manual insertion and removal of bags. This class of filler is typically equipped as standard with fill head height adjustment via fork truck to accommodate all popular bag sizes, a feed chute vent port for dust-free air displacement during filling and an inflatable cuff to seal against the bag inlet spout and ensure it does not collapse on itself during filling. The cost of a scale system can be avoided by placing the entire filler onto an all-purpose plant scale, providing the filler is properly equipped for in-plant mobility. Alternatively, if a forklift is unavailable to remove filled bags, configurations are available with a three-sided base that provides access from the open side using a pallet jack. The time required to prepare empty bags for filling, and to remove filled bags from beneath the filler, can have as much or greater influence on maximum filling capacity than the rate at which material enters the bag. As such, adding a roller conveyor allows filled bags to be rolled out of the filling area for spout cinching and pallet/bag removal while another bag is being filled. Adding such a conveyor system, however, generally requires a filler with rear posts and a cantilevered fill head equipped with hooks that release bag loops automatically, so if higher capacity is in your future, a rear post configuration may be your best choice today. Further increasing the capacity of systems equipped with roller conveyors to the next level generally entails adding an automated pallet dispenser which places pallets and slip sheets onto the roller conveyor upstream of the filling operation, further reducing the time required for each filling cycle by limiting manual operations within the filling station exclusively to loading an empty bag.

When a an inflatable spout seal to hold the bag spout firmly in place pneumatic conveyor is used as the material delivery system, during filling.

It is therefore important to confirm that the filler you are considered when using mechanical metering devices to move considering is so equipped, particularly when contamination of material to the filler from both storage vessels and plant processes. the product or plant environment cannot be tolerated.

4. Determine your need for multifunction filling If your plant fills drums, boxes or other containers as well as bulk bags, multifunction fillers can boost production, undercut the cost of separate equipment and reduce the amount of floor space required. Multifunction fillers can be switched from bulk-bag to drum-filling mode in seconds by positioning the swing-arm-mounted drum-filling chute under the fill head discharge port. The chute automatically rotates to deliver material to all four drums on a pallet. Similar adapters for boxes, totes or other containers are also available with varying levels of automation.

5. Match the feed source to your material and your filler Filling capacity, accuracy and efficiency are often limited by the ability of upstream equipment to feed material consistently and in sufficient volumes. High-capacity, semi- or fully automated fillers therefore require high-capacity feeding systems that are typically automated and feed material into the filler by gravity or by a metering device. The ability to gravity-feed material depends on whether a material storage vessel can be located above the filler and on the materialâ&#x20AC;&#x2122;s flow characteristics. The more free-flowing it is, the more accurately its flow can be varied (down to dribble92

6. Comply with sanitary requirements

While all fillers can be constructed of stainless steel with ground and polished welds, their designs can preclude sanitising according to government standards. If your application must meet sanitary requirements, your choices should be limited to designs that are accepted by the agencies to which you must comply, or to which you elect to comply for assurance that sanitary conditions can be maintained.

Conclusion With an almost unlimited combination of filler designs, features and upstream equipment from which to choose, specifiers have the ability to tailor bulk bag filling systems according to capacity requirements, expandability, safety concerns, plant hygiene considerations, ancillary filling needs, upstream equipment and sanitary standards. While numerous available options can complicate the selection process, they can also yield a highly efficient and cost-effective solution to any given filling problem, providing that fundamental steps are taken to evaluate equipment against precise requirements.

The dust-free system comprises a receiving hopper, dust collector, bag compactor and flexible screw conveyor. A bag infeed chute through the sidewall of the hopper hood allows the operator to pass empty bags directly into the bag compactor, causing dust generated from both tipping and compaction to be drawn onto the system’s two cartridge filters. An automatic reverse-pulse filter cleaning system releases short

blasts of compressed air inside the filters at timed intervals causing dust build-up on the outer surfaces to fall into the hopper, conserving useable product. Filters are readily accessed by removing the interior baffle and replaced rapidly using quick-disconnect fittings. The compactor employs a large pneumatic air cylinder to compress bags into a removable bin that accommodates 50 to 80 bags. The main door and a flapper door within the bag infeed chute are equipped with safety interlocks that prevent operation of the compactor unless both doors are closed. The hopper discharges into an enclosed, flexible screw conveyor designed to handle a broad variety of materials including free-flowing and non-free-flowing bulk materials from large pellets to submicron powders, including products that pack, cake, seize, smear, fluidise, break apart or separate, with no separation of blended products.

Waterproof pallet wrapping TechnoWrapp has upgraded its A800 and A800 4E automatic ring wrapping machines with an integrated top sheet applicator. The high-speed machines are for wrapping palletised loads with stretch film and a waterproof top sheet. These highly productive wrapping machines are designed to keep film usage to a minimum with up to 350% material savings claimed, and yet ensure complete hermetic sealing of the pallet stack. The ring technology rotates the film cartridge around the palletised load, combining smooth horizontal and vertical movements to cover the load, while still maintaining the integrity of the load corners.

BULK HANDLING, STORAGE & LOGISTICS

TechnoWrapp has integrated top sheet applicators that place a sheet of polyethylene on the top of the load which, together with the lateral wraps, creates a waterproof covering of the product. The electronic prestretch system with a tacho generator enables smooth dispensing of the film and a high degree of prestretch. The wrapping machines use as little as 96 g of film, which is achieved by prestretching the film to more than 400%. On a pallet measuring 800 x 1200 x 1500 mm high, using nine layers of film and a standard film reel of 500 mm wide x 23 Âľm, only 96 g of film is used. The pallet/load is static so the stability and integrity of the stack is maintained during the high-speed wrapping process. The automatic pallet stretch wrapping machines can wrap up to 130 pallets/h and hermetically seal the top and sides of the load. Optional extras include an auto reel changeover, stretch film splicer and pallet lift in wrapping area. HBM Packaging Technologies Contact info and more items like this at wf.net.au/M233

Intelligent cargo for more efficient, greener logistics Smart cargo that knows where it is, where it is going, when it needs to be there and who is handling it would revolutionise the freight industry, improving efficiency, saving suppliers and recipients time and money, and helping protect the environment. EU-funded researchers have developed a proof-of-concept ‘intelligent cargo’ system that promises all those benefits and more.

M

illions of trucks, freight trains and cargo ships are on the move around the world each day. Combined, they account for more than 14% of global greenhouse gas emissions and consume around a third of total energy consumption. Wastefully, many of those vehicles are travelling empty. Despite efforts to improve freight transport efficiency, a cargo truck plying Europe’s roads will currently still spend around half of its working life empty - returning from a delivery or travelling to pick up its next shipment. But what if cargo was made aware of its context and purpose? It could find space on a passing truck, let logistics operators know where it is and keep recipients informed of its estimated time of arrival. Perishable and hazardous goods could be closely monitored, transport routes dynamically changed to avoid congestion and the entire transport industry made dramatically more efficient. “Put simply, intelligent cargo is about giving cargo the capacity to understand who I am, where I am, what my mission is and what I should do if something goes wrong,” said 96

September/October 2012

Margherita Forcolin at IT services company Insiel in Italy. “From an artificial intelligence point of view, it’s a basic level of intelligence - it simply reacts to what’s going on around it, but from a logistics viewpoint it’s a huge step forward.” Insiel coordinated a consortium of 22 companies, universities and research institutes in defining concepts and developing technology for an intelligent cargo system based on a combination of sensor networks, wireless communications and ambient and artificial intelligence. Supported by €8.25 million in funding from the European Commission, the team behind the EURIDICE (European Inter-disciplinary Research on Intelligent Cargo for Efficient, Safe and Environment-Friendly Logistics) project implemented their system in eight different pilot studies involving transport and logistics operators across Europe. EURIDICE aimed to use ‘cooperative systems’ - systems (or objects) that communicate with each other and their surroundings - to provide the right information in the right place at the right time at low cost, using modern communication networks.

BULK HANDLING, STORAGE & LOGISTICS

Intelligent cargo The EURIDICE definition of intelligent cargo is built on six key capabilities. To begin with, the cargo needs to be able to identify itself so an operator at a warehouse can ask a container, pallet or box for its unique ID and determine what is inside. The operator, in turn, should then be able to access information services from the owner, haulier and customs authority to determine the nature, route and clearance status of the goods. The cargo also needs to be aware of its context, enabling it to report, for example, that it is inside a truck on the road or waiting to be picked up in a storage depot. It should also monitor and report its status, which, depending on the type of cargo, could mean checking its temperature, humidity and whether it is still sealed or has been hit or damaged in any way. This information, combined with artificial intelligence technology, enables the cargo to act independently and make autonomous decisions; for example, alerting logistics planners automatically if it deviates from the predefined route, if there is a delay. “There are two parts to the system: the sensors, data storage, software and transmission components on the cargo and a connected fixed infrastructure that handles the overall management of the system,” explains Forcolin, who coordinated the development and deployment of EURIDICE. Precisely what components need to be used and how depends on the intended application. A shipping container, for example, could be fitted with a range of sensors to monitor all of its contents and its whereabouts, whereas a product package could be tagged with an RFID chip that simply tells logistics operators what it contains and where it is going. The back-end infrastructure is similarly flexible. It could be installed by a logistics company to manage all of its operations or by a third-party service provider offering services to a cluster of transport firms, suppliers and product recipients. “There are many different business models we have looked at. Ultimately, how a system like this is implemented and used will be determined by the end users and the market,” Forcolin notes. “The overall concept is to have cargo that is able to communicate important information about itself to the infrastructure and from there to all the stakeholders in the transport chain. Though we talk about intelligent cargo, from a technical viewpoint it’s really cargo intelligence - it’s a distributed intelligence achieved through different means and processes.”

Solving real-world problems The enormous potential of the approach was demonstrated by the EURIDICE team in eight pilot implementations that showed how intelligent cargo and cargo intelligence can solve a variety of real-world problems within different areas of the freight industry.

September/October 2012

A shipping container, for example, could be fitted with a range of sensors to monitor all of its contents and its whereabouts, whereas a product package could be tagged with an RFID chip

One pilot focused on using the system to interconnect transport and production processes. Working with Italian eyewear manufacturer Safilo, a project partner, technology was implemented to provide the company with automated real-time information about the whereabouts of eyewear components, from before they leave the supplier’s factory until they check in at the company’s warehouse. Equipped with the real-time information about all the parts - even from different suppliers - Safilo could better schedule assembly and manufacturing processes, avoiding delays, reducing costs and improving production efficiency. With Fiorital, another pilot end user, the logistics requirements were different. The company deals with the distribution of perishable consumer goods such as fresh fish and needs to closely monitor the status, storage conditions and transport history of its products. In the trial, the EURIDICE implementation enabled Fiorital to monitor in real time the temperature and conditions of the product during transport and receive automated alerts in the event of an incident. And what happens after the goods have been safely delivered on time? With Gebrüder Weiss, an Austrian logistics service provider, the EURIDICE system was implemented to optimise the return of empty pallets and boxes and ensure that trucks do not return empty. The trucks automatically advertise that they have space available and the boxes and pallets inform operators that they have been unloaded and are waiting to be returned. “Individually, the pilots represented elements of a real-world supply chain. Together, they covered an almost complete supply chain scenario,” Forcolin said. “There are so many possibilities for this type of intelligent system. Looking ahead, I can imagine having an intelligent system on the cargo communicating with the vehicle, which in turn communicates with the transport infrastructure, the roads, ports, etc - it’s the vision of the ‘Internet of Things’.” With several of the partners continuing to build on the work carried out in EURIDICE, that vision of a more intelligent, more efficient and more environmentally friendly transport sector could come about sooner rather than later.

New racking standard brings Australia up to date

T

he new standard will bring Australia up to date with the latest international knowledge and experience in the design of storage systems and cold-formed steel structures.

Racking is a system, not a product Even though each component of a steel racking system may be a ‘standard’ component, compliance with the standard depends on how these components interconnect to make a system, the level of load it is required to hold, the presence or absence of seismic loads and so on. Essentially, compliance with AS4084-2012 is a rack-by-rack, application-dependent proposition. While the designer is responsible for ensuring the steel racking systems are fit for purpose, meet the user’s requirements and budget, and provide acceptable safety margins to ensure safe, long-term operation, the responsibility of ensuring the systems are properly used and maintained falls squarely on the user.

Key changes to design The major change to the Australian steel storage racking standard is the switch from using a “permissible stress” design philosophy to a “limit states” design approach. This change brings the Australian standard into line with most of the advanced rack design codes in the world, including the European racking standard EN15512:2009 and the Rack Manufacturers Institute Specification from North America. It also brings the standard into line with the relevant crossreferenced companion Australian standards including AS/ NZS4600:2006 Cold Formed Steel Structures and AS41001998 Steel Structures. From a structural design perspective, the limit states approach offers advantages over the permissible stress format. It allows the designer to consider the application of different margins of safety to different types of loads (dead loads, storage loads, live loads, seismic loads) to facilitate design optimisation, while guaranteeing a prescribed level of safety across different combinations of loads. Other changes in the new standard include expanded and improved testing provisions, including statistical evaluation, and the inclusion of advanced methods of structural analysis and finite element analysis. Compared to the 1993 standard, the new standard has the potential to result in more structurally efficient and finely tuned designs. The result is that modern storage racks are generally lighter and cheaper than older racks, while still possessing the required minimum level of structural safety good news for end users. 102

September/October 2012

A new standard covering the design of steel storage racking systems was released on 29 February 2012, after the previous standard remained unchanged for 18 years. The new standard is called AS40842012 Steel Storage Racking. Dr Murray Clarke, Structural Design Manager, Dematic, discusses some of the key changes in the standard.

Key changes to operational requirements and end-user responsibilities Users should be aware of a number of important changes: • No changes to storage system configuration are allowed without the approval of the equipment supplier or a structural engineer. • The vertical clearance requirement for pallets stored above heights of 6 m has been increased from 75 to 100 mm. This is aimed at reducing the risk of accidental impact with beams during pallet put-away and retrieval. • The ‘flue space’ between pallets backing on to each other has been increased by 50 mm, reducing the risk of an adjacent pallet being accidentally dislodged when storing or retrieving pallets. • A minimum of two ground anchors must be used per baseplate on racks where forklifts are used. • Minor changes to rack load signage whereby the dimension from ground to first beam level and from first to second beam level must be noted explicitly on signs.

User responsibilities Storage system users should ensure their systems are professionally audited each year. Many storage system users are either unaware or routinely ignore these requirements. Recent rack collapses in New Zealand have shown the importance of regular system audits to identify existing rack damage that could compromise performance during a seismic event or overloading of the structure. Failure to conduct annual audits could expose users to litigation and potential penalties should an incident occur.

What the standard doesn’t cover Like the standard before it, the new steel storage racking standard is only relevant for closed-face racks such as ‘selective’, ‘narrowaisle’ and ‘double deep’ racking. It does not cover open-face racks such as ‘drive-in’ or ‘cantilever’ racking. When designing open-face racks, designers will need to seek guidance from other international standards and codes such as FEM 10.2.07 for drive-in racking and FEM 10.2.09 for cantilever racking. These codes can be used in conjunction with AS/NZS4600-2005 Cold Formed Steel Structures to obtain structurally sound racking designs consistent with best practice. Dr Clarke is a member of the Standards Australia committee for steel storage racking and represents Dematic at the European Racking Federation (ERF) technical meetings. The ERF is a division of the widely known European industry body Fédération Européenne de la Manutention (FEM). Dematic Pty Ltd Contact info and more items like this at wf.net.au/N774

Chocoholics rejoice

Chocolate lovers have long been hoping for scientific evidence that chocolate is good for you.

T

he study, published i n the journal Hypertension, examined the effect of regular cocoa flavanol consumption on cognitive function in people with mild cognitive impairment (MCI). While cocoa flavanols have been shown to help support circulation and cardiovascular health, the study builds on previous research that suggests cocoa flavanols may benefit the brain. “For the first time, regular cocoa flavanol consumption has been shown to positively affect cognitive function in older adults with early memory decline,” said Dr Giovambattista Desideri, author of the study and Director of the Geriatric Division of the University of L’Aquila. “Importantly, the improvements in cognitive function were seen over a relatively short period of time; and, while further research is required to confirm and expand on these findings, this provides encouraging evidence that regular consumption of cocoa flavanols might be effective in improving cognitive function in elderly subjects with mild cognitive impairment. The findings provide promising indications that the development of novel dietary approaches for improving health as we age - especially cognitive health - is a real possibility.”

The study The researchers based the study on the hypothesis that regular consumption of cocoa flavanols would positively affect cognitive performance in people with MCI, which is a condition in which people experience greater memory loss than is expected for their age but is not so severe as to impact on daily activities. Up to 20% of people over 65 have MCI and more than 6% of people aged 70 to 89 develop MCI each year. The study saw 90 healthy older people with MCI consume a cocoa flavanol drink that contained high (HF), intermediate (IF) or low (LF) amounts of cocoa flavanols (approximately 990, 520 or 45 mg of flavanols respectively). The participants consumed the drink once a day for eight weeks but did not change their diets otherwise. The taste and appearance of all the drinks was the same and they were calorically and nutritionally matched, enabling the blinding of product identities throughout the study. The HF and IF drinks were produced by Mars using its Cocoapro process, while the LF drink was made with a highly processed, alkalised cocoa powder.

Benefits for an ageing population “We already understand how important diet is to health and previous research has provided consistent evidence of the benefits of cocoa flavanol consumption for cardiovascular health,” said Catherine Kwik-Uribe, a study author and R&D Director at Mars Botanical. “The results of this latest research build on these earlier findings and provide promising indication that diets that contain cocoa flavanols may offer significant benefits as we age. This is of great interest given the ageing populations in much of the developed world.” Harold Schmitz, Executive Director of the Mars Center for Cocoa Health Science, said the study has improved understanding of cocoa flavanols and may one day lead to dietary recommendations for cocoa flavanol intake. So there’s good and bad news for all the chocoholics out there. On the one hand, chocolate consumption could soon be considered part of a healthy diet. On the other, you might have to wait until your memory starts to falter before the doctor prescribes a family-sized block of chocolate. No doubt self-medication for MCI will go through the roof. 106
