Abstract
A casein phosphopeptide composition is prepared containing less than 4% phenylalanine, tyrosine and tryptophan, greater than 8% and less than 20% serine, a ratio of Ca+Mg+P/N.sub.T greater than 0.2, wherein N.sub.T is the total nitrogen content times 6.38, and free amino acids of less than 3%. The composition is useful as an ailment for dietetic or therapeutic nutrition or as a medicament. Salts of the phosphopeptides may be formed from macroelements such as calcium and/or magnesium and/or from oligoelements such as iron, zinc and copper. The composition is produced by proteolytic enzyme hydrolysis of a casein-based material, and using ultrafiltration and aggregration with a bivalent cation salt to isolate the phosphopeptide composition.
