ABSTRACT:
Casein phosphopeptide salts of calcium, magnesium or both are produced having less than 4% by weight of aromatic amino acids, greater than 8% and less than 20% by weight serine, less than 3% free amino acid content and a ratio of total calcium, magnesium and phosphorus to total nitrogen greater than 0.2. The phosphopeptides are produced by subjecting a casein material to proteolytic enzyme hydrolysis ultrafiltering the resulting hydrolyzate to produce a permeate containing phosphopeptides, adding a bivalent cation salt to the peptides to form phosphopeptide aggregates and separating by ultrafiltration the phosphopeptide aggregates from non phosphorylated peptides. The phosphopeptides obtained are useful as aliments for dietetic or therapeutic nutrition and as medicines.
