NON-PHOSPHORYLATED PEPTIDES FROM CASEIN-BASED MATERIAL |
摘要 |
Non-phosphorylated peptides and phosphopeptides useful as alimentary products or medicaments are produced. A hydrolyzate containing non-phosphorylated peptides and phosphopeptides is prepared by proteolytic enzyme hydrolysis of a casein-based material. The hydrolyzate is subjected to ultrafiltration with a membrane which allows peptides to pass through to produce a permeate containing the non-phosphorylated peptides and phosphopeptides. A bivalent cation-containing salt capable of aggregating the phosphopeptides is added to the permeate to produce a mixture containing phosphopeptide aggregates and non-phosphorylated peptides. The mixture is subjected to ultrafiltration with a membrane that retains the phosphopeptide aggregates and separates them from the non-phosphorylated peptides. The phosphopeptides form salts, which have dietetic uses, with macroelements such as calcium and/or magnesium and/or oligoelements such as iron and zinc.
