COLLAGEN PEPTIDE COMPOSITION AND FOOD OR BEVERAGE CONTAININGTHE SAME

摘要

The object is to discover a collagen peptide composed of an oligopeptide having a higher ability of being transported into the blood compared to a co nventional collagen peptide, and to provide a food or beverage having the co llagen peptide blended therein. Disclosed is a collagen peptide composition produced by digesting a collagen or gelatin with a protease. The collagen pe ptide composition comprises 70 to 100 wt% of a peptide having a molecular we ight of 500 to 3000 inclusive, less than 10 wt% of a peptide having a molecu lar weight of less than 500, and less than 20 wt% of a peptide having a mole cular weight exceeding 3000, wherein the ratio of glycine in the N-terminal amino acid residues of the peptides contained in the composition is 33 to 65 mol% inclusive.
