Whey powder

Whey powder is a by-product of cheesemaking, derived from milk. It is produced by drying liquid whey, which separates from milk curds during the cheese-making process. The resulting powder is a source of protein and lactose.

Manufacturers add whey powder for its nutritional content and functional properties, such as improving texture and aiding browning. It is commonly found in baked goods like biscuits and cakes, as well as in confectionery, processed meats, and infant formulas.

Whey powder is not classified as a food additive and therefore does not have an E-number or require authorisation on the Register of Food Additive Authorisations. It is a source of protein and other nutrients naturally present in milk. The UK's Eatwell Guide advises that dairy products like milk, cheese, and yogurt should be part of a balanced diet. There is ongoing research into the potential health benefits of whey protein, but no specific health claims are made here.
