Caseinate is a type of protein derived from milk. It is a form of casein, which is the primary protein in milk. When milk is processed, the casein is separated from the whey and then further processed to create caseinate. Caseinate is a water-soluble protein that is often used in food manufacturing. Caseinate is used in many processed foods, including baked goods, confectionery items, and meat products, to improve texture, increase protein content, and extend shelf life.
