Whey Protein

Whey protein is a mixture of proteins found in the liquid left behind after milk has been strained and curdled, such as during cheesemaking. It is typically produced by separating whey from casein, the main protein in milk. The liquid whey is then processed to concentrate and isolate the whey proteins.

Whey protein is often added to foods as a protein supplement, to improve texture, and to enhance browning. It is commonly found in baked goods, protein bars, dairy products, and nutritional beverages.

Whey protein is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a source of high-quality protein, which plays a role in muscle building and repair. Regulatory bodies like JECFA and EFSA have evaluated whey protein and its components. While generally considered safe, some individuals may experience digestive discomfort. Research into the specific health effects of high protein intake is ongoing.
