Calcium caseinate is widely used in the food industry as a source of high-quality protein and functional ingredient. It improves texture, stability, and nutritional value in various products. Commonly found in protein powders, nutritional supplements, and meal replacements, it supports muscle growth and recovery due to its slow digestion rate. It is also used in processed cheeses, coffee whiteners, and baked goods to enhance protein content and emulsification properties. In addition, calcium caseinate acts as a foam stabilizer in whipped toppings and beverages. Its ability to bind water and fat makes it valuable in meat and meat analog products to improve juiciness and shelf life. Due to its film-forming properties, it is sometimes used in edible coatings to extend freshness. Furthermore, it finds applications in the cosmetics industry to nourish skin and hair, leveraging its moisture-binding and slow-release nutrient properties.
