Dry whey is the product resulting from drying fresh whey which has been pasteurised and to which nothing has been added as preservative. It contains all constituents, except moisture, in the same relative proportions as in the liquid whey.
Whey protein is commonly used for improving athletic performance and increasing strength, but evidence to support these uses is mixed. Whey protein is also used to reverse weight loss in people
Rich source of carbohydrates, good emulsification and browning properties, economical substitute of milk solids.

As a food additive, whey powder acts as binder and extender for many food products, such as beef preparations, chili con carne, poultry, sausage, soups and stews.
