What it is

Whey protein is a byproduct of cheesemaking. It is the liquid remaining after milk has been curdled and strained. This liquid is then processed to isolate the protein components.

Why it's used

Whey protein is added to foods as a protein supplement and to improve texture. It can act as a binder and emulsifier. It is commonly found in protein bars, nutritional shakes, baked goods, and some dairy products.

Health notes

Whey protein is generally recognized as safe (GRAS) by the FDA for use in food. It is a complete protein, containing all essential amino acids, and is a popular supplement for muscle growth and recovery. International bodies like JECFA have evaluated whey protein, but no specific numeric limits are typically set for its use as a food ingredient.

Allergen info

Whey protein is derived from milk, which is one of the 9 FDA major allergens. It does not contain gluten.
