Casein (CAS NO : 9000-71-9)

Casein is a family of phosphoproteins, crucial milk proteins used in food, feed, and nutraceutical formulations. Casein from bovine milk refers to the first primary protein found in cow's milk, comprising about 80% of the total protein content. Casein has complex colloidal structures called casein micelles, formed by four types of proteins (αS1-, αS2-, β-, and κ-casein) bound with calcium & phosphate. This derived protein has vital nutritional value and functional properties. Bovine beta-casein monophosphopeptide functions and behaves as a high-quality protein source, emulsifier, and functional ingredient in dairy products, protein powders, and infant formulas, as well as dietary supplements, including its role in emulsion, thickening, and texture. Supplied in food grade, it ensures consistent quality for B2B manufacturers, nutraceutical formulators, and food product developers.
