Whey | Overview
WheyLiquid obtained from cheese manufacture. is a collective term referring to the serum or watery part of milk that remains after coagulation, which occurs primarily in the production of cheese and cottage cheese. The composition of wheyLiquid obtained from cheese manufacture. varies considerably, depending on the milk source and the manufacturing process involved. But in general, wheyLiquid obtained from cheese manufacture. is rich in lactose (milk sugar)White to creamy white crystalline product, possessing a mildly sweet taste. It may be anhydrous, contain one molecule of water of hydration, or be a mixture of both forms. It is manufactured from whey or permeate by evaporating, crystallizing, refining and then drying the lactose crystals., mineralsGenerally refers to elements other than carbon (C), hydrogen (H), oxygen (O) and nitrogen (N) that are found in dairy products. The term often is used interchangeably with salts and ash., vitamins, and “wheyLiquid obtained from cheese manufacture. proteins.”
Grade “A” dry whey must be produced with Grade “A” whey in a Grade “A” plant. All other parameters for Grade “A” products are the same as “Extra Grade.”
Natural, functional, and high in nutrition, wheyLiquid obtained from cheese manufacture. is the ingredient of choice for product developers. WheyLiquid obtained from cheese manufacture. ingredients have applications in baked goods, beverages, confections, dairy foods, meat products, salad dressings, nutraceuticals, sauces, and soups—with new uses continuously being identified.
Whey Products Standards
The wheyLiquid obtained from cheese manufacture. processing industry initiated the development of standards for condensed and dry wheyFresh whey that has been pasteurized and contains all constituents, except water, in the same proportions as found in the original whey and wheyLiquid obtained from cheese manufacture. products immediately after the founding of the WheyLiquid obtained from cheese manufacture. Products Institute in 1971.
U.S. Standards for Dry WheyFresh whey that has been pasteurized and contains all constituents, except water, in the same proportions as found in the original whey that include both sweet- and acid-types now exist as a result of cooperative efforts between industry and government. Uniformity of product qualityFocus on doing things well and producing a product acceptable to consumers is ensured through grade specifications that are universally accepted and understood.
ADPIAmerican Dairy Products Institute task forces have developed industry standards for a number of additional dry ingredient products derived from wheyLiquid obtained from cheese manufacture.. Through such standards, wheyLiquid obtained from cheese manufacture. processors, and users/purchasers, have a clear understanding of product qualityFocus on doing things well and producing a product acceptable to consumers and the basis upon which such has been determined. Questions relating to a product’s qualityFocus on doing things well and producing a product acceptable to consumers thus may be eliminated by having standardized analytical test methods available to both buyer and seller and by referring these test results to specific grade standards.
Methods of analyses needed to accurately determine product composition, measure qualityFocus on doing things well and producing a product acceptable to consumers, and ascertain compliance with grade standards, have been reviewed and approved by an Institute Committee of technical experts, and are compiled in each standard.
In addition, several wheyLiquid obtained from cheese manufacture. products have received GRASGenerally recognized as safe affirmation and GRASGenerally recognized as safe Notification and are listed in the appendices of this section.
How to Choose Between a Milk or Whey Ingredient
Milk and wheyLiquid obtained from cheese manufacture. ingredients provide multiple benefits to food products. These benefits are often described as flavor, function, and nutrition. They provide a mild, dairy flavor that blends well with many food products. Their composition can consist of multiple components such as, proteins (caseins and/or wheyLiquid obtained from cheese manufacture. proteins), milkfat, lactose, and ash (mineralsGenerally refers to elements other than carbon (C), hydrogen (H), oxygen (O) and nitrogen (N) that are found in dairy products. The term often is used interchangeably with salts and ash.), and thus provides many different functional properties described in the table below. These components also provide many of the same unique nutritional properties found in milk.
Milk and wheyLiquid obtained from cheese manufacture. ingredients are used in a wide variety of food products including dairy products, baked products, confections, soups, sauces, infant formula, processed meats, prepared foods, and beverages. Selecting the right dairy ingredient for your application can be confusing because many milk and wheyLiquid obtained from cheese manufacture. ingredients have a similar composition, for example nonfat dry milk (NDMNonfat dry milk) and whey proteinProtein in milk that remains in water phase after casein precipitates. concentrate 34 (WPC34). Even though the protein content is about the same, NDMNonfat dry milk consists of roughly 80% caseinProtein in milk that precipitates at pH 4.6. and 20% whey proteinProtein in milk that remains in water phase after casein precipitates., while WPC34 is all whey proteinProtein in milk that remains in water phase after casein precipitates.. Often the choice is made based on price, but comparing the differences in functionality is probably the most important method of selection.
SolubilityAbility of a liquid to dissolve another material. Examples: Lactose dissolving in water, alcohol dissolving in water. in water is the single most important functional property for a milk or wheyLiquid obtained from cheese manufacture. ingredient. No matter which ingredient you choose, it must be soluble for it to be functional. The solubilityAbility of a liquid to dissolve another material.

These are the primary characteristics to help select the right dairy ingredient for your application.
Functional Benefits of Milk & Whey Ingredients
Function | Primary Components | Benefits |
---|---|---|
Solubility | Protein | Provides better performance in all applications |
Browning | Protein and Lactose | Provides color and flavor development |
Emulsification | Protein-caseins provide stronger emulsification than whey proteins | Provides binding and separation of fat globules and texture stability |
Heat Stability | Protein-caseins are more heat stable than whey proteins | Prevents protein aggregation and settling for properly hydrated ingredients during high heat processing |
Gelling & Heat Setting | Protein-whey proteins will denature and form gels with heat treatment | Provides structure and water holding properties |
Water Binding & Viscosity Building | Protein-caseins have more water binding ability than whey proteins | Improves texture and mouthfeel; Helps to retain moisture and improve shelf life |
