Calcium caseinate

Calcium caseinate is a protein derived from casein, the main protein found in milk. It is produced by treating skimmed cow's milk with acid or rennet to precipitate the casein, which is then washed, neutralised with calcium hydroxide, and dried. This process results in a white to off-white powder.

Manufacturers add calcium caseinate as a protein source and emulsifier. Its ability to bind water and fat makes it useful in processed foods. It is commonly found in protein bars, supplements, baked goods, and some dairy products to improve texture and nutritional content.

Calcium caseinate is authorised as a food additive in Great Britain and listed on the Register of Food Additive Authorisations. European food safety authorities (EFSA) have evaluated it. Like other dairy proteins, it is a source of calcium and amino acids. At typical intake levels found in food, it is not associated with adverse health effects.
