Description

Casein CAS NO 68308-23-6 is a family of related phosphoproteins, primarily derived from milk, that serves as a fundamental protein source and functional ingredient. Its unique ability to form gels, bind water, and act as an emulsifier makes it indispensable for creating specific textures and enhancing nutritional profiles. This versatile protein is essential for manufacturers in the food and beverage, nutraceutical, and industrial adhesives sectors seeking reliable, high-quality protein ingredients.

Application

• Food & Beverage: Key protein fortifier in nutritional supplements, meal replacements, and sports drinks; used as a texturizing and emulsifying agent in processed cheeses, coffee whiteners, and whipped toppings.
• Pharmaceutical & Nutraceuticals: Acts as a slow-release carrier matrix in tablet formulations and provides a high-quality protein base for medical nutrition products and dietary supplements.
• Technical & Industrial: Serves as a binder in paper coatings, water-based paints, and adhesives (e.g., wood glue); used in the manufacture of plastics and fibers.
• Cosmetics & Personal Care: Functions as a conditioning agent and film-former in hair care products and skin creams.
