Proteins From Whey

Whey proteins are a group of proteins derived from whey, the liquid by-product of cheese and casein production. They are separated from the fat and casein in the milk and then processed into a powder form through various drying techniques.

Manufacturers add whey proteins for their nutritional value as a source of high-quality protein, and for their functional properties like emulsification and water-binding. They are commonly found in protein bars, confectionery, baked goods, and dairy-based products.

Whey protein is not classified as a food additive in the UK and does not have an E-number. It is a source of protein, which is an essential nutrient. Regulatory bodies like EFSA have evaluated whey proteins in the context of food safety and nutritional claims. Evidence generally supports whey protein as a safe and beneficial dietary component, particularly for muscle growth and repair when consumed as part of a balanced diet.
