Casein is widely used in the food industry as a protein source, particularly in dairy products like cheese and yogurt. It acts as a thickening agent, stabilizer, and emulsifier, enhancing texture and consistency in products such as ice cream, baked goods, and processed meats. In the pharmaceutical industry, casein is utilized in the production of slow-release tablets due to its ability to form a gel-like matrix that controls drug release. Additionally, it is employed in adhesives, paints, and coatings, where it serves as a binder or film-forming agent. In cosmetics, casein is incorporated into hair and skincare products for its moisturizing and conditioning properties. It also finds applications in the textile industry as a sizing agent to strengthen fibers during weaving.
