Standards of FINISHED Pasta Measurement

An explanation of how we measure finished pasta products.


Introduction This booklet details the PMC Measurement Standards. The methods and tools detailed in this booklet are the only acceptable methods for measuring product. At Philadelphia Macaroni Company, we are committed to providing pasta that CONSISTENTLY meets the specifications required by our customers. All product must meet a set of standards which has been established by the Quality Assurance team. By following the same measuring standards, we ensure the customer receives product which is consistent.

Measurement Piece Counts How many pieces are measured? Refer to chart below.

Certificate of Analysis - Physical Dimensions

30 units/pieces of product

New Die

100 units/pieces of product

Re-Tooled Die

100 units/pieces of product

Question: Why measure those quantities? Answer: A Minimum Piece Quantity is required so that a representative sample of the product is used.

Customer Specifications may call out different minimum numbers

Description or PMC Definition

Bulk Density

Measured in grams per ml (milliliter) using a graduated cylinder and electronic scale. See Bulk Density SOP page in this booklet. Bulk Density will be called out in the customer’s specification if required.

Calibration

The process of qualifying and adjusting the measuring tools used. This ensures the tools are correctly measuring product. See Calibration SOP in this booklet

Curl or Ripple

In mafalda and lasagna this is bump on the outer ridge

Curvilinear

This measurement is of the curved-length of shells or elbows.

Flights

The number of twists in a spiral or rotini

I.D.

Inside Diameter is measured on the inside of an elbow or tube – not a standard measurement but sometimes called out on customer specifications

Long Goods

Lasagna, spaghetti, fettuccine, linguine

Noodles

A noodle is any pasta product that contains 5.5% whole egg

O.D.

Outside Diameter – the length of a straight line passing through the center of a circle and connecting two points on the circumference

Ridge

The high points on corrugated shapes such as penne and shells.

Short Goods

Shells, Elbows, Tubes, Spirals, Orzo, ABC’s, Wheels, Rotini

Specification

A document which details the formulation, physical dimensions and other customer requirements for a product

Tip to Tip

Measuring pasta from the longest point to the longest point.

Piece Count

The number of pieces of product per a specified weight

Twists

Also known as flights in a spiral rotini; counted in curly noodles

Valley

The low points between the ridges on corrugated shapes such as penne and shells.

Vane

Is the lip of a rotini or radiatore – items may be described as 2-vane or 3-vane. Often this word is mis-spelled as vein
