Casein Phosphopeptides (CPP) are phosphorylated peptides derived from enzymatic hydrolysis of casein that bind calcium, iron and zinc in soluble form, enhancing mineral bioavailability.We supply bulk Casein Phosphopeptides sourced from leading China manufacturers, available in powder form for international food processing operations. Our Casein Phosphopeptides is widely used in beverages, oral care, paediatric nutrition, osteoporosis supplements and zinc fortification carriers. HS Code: 29309099
Casein Phosphopeptides are produced by tryptic hydrolysis of casein, followed by selective precipitation, purification and spray drying.
The phosphoseryl clusters chelate divalent minerals (Ca²⁺, Fe²⁺, Zn²⁺), keeping them soluble through the intestinal tract and enhancing absorption. CPP is the active principle in remineralising dental products and calcium-bioavailability enhancers.
