New Brewer’s Yeast developed specifically for use in animal feed
News
I
nactivated and autolysed brewers’ yeasts have been used for a long time as natural and sustainable ingredients to increase the acceptance of various feeds. Furthermore, thanks to their multifunctional components such as peptides, amino acids and nucleotides, brewers’ yeast extracts offer unique taste effects and functions. Leiber developed Leiber NuTaste® specifically for uses of brewers’ yeasts for animals. Leiber NuTaste® products offer a portfolio of natural flavours, which can be deployed either pure or in combination with other yeast extracts. NuTaste, thereby offering a very broad spectrum of applications for product developers and ration optimisers, based on the enhanced attractiveness, tastiness and taste improvement of feeds and the corresponding increase in feed intake. Leiber’s in-house production methods ensure valuable, standardised food-quality products with unique taste profiles ranging from brothy, meaty and savoury to umami and roast-flavoured BBQ-like tastes. As well as flavour, some NuTaste products have additional colouring or nutritional effects. This means that the products can be used for example for enhancing individual flavours, lowering the salt content in the product, replacing artificial colourants as well as for vegetarian and vegan applications in petfood. Therefore Leiber’s NuTaste covers a large number of customer-specific requirements and applications.
