Camel whole casein and -CN showed significant ACE-inhibitory activities after hydrolysis with pepsin alone and after pepsinolysis followed by trypsinolysis and chymotrypsinolysis. Enzymatic hydrolysis of casein to produce free amino acids by papain was performed in a kind of novel two-phase system, which was composed of n-propanol, NaCl and water. casease, casein. The primary function of casein enzyme in the body is to digest proteins and other nutrients in the digestive tract. Milk Agar -- milk protein (casein), peptone (nutrient source), beef extract (nutrient source and chemically undefined), and agar. The relationship between enzymatic hydrolysis and structure change of casein need to make more study. Hydrolysis was performed using a mixture of trypsin and chymotrypsin (enzyme/substrate ratio, 1/1,000 [wt/wt]). Casein hydrolysates were evaluated for the degree of hydrolysis, antioxidant activity, molecular weight distribution patterns and peptide sequence. It is a refined product providing high quality soluble source of amino acids, polypeptides and peptides.
