A blood glucose level increase inhibitor, a blood glucose level increase suppression food, and a blood glucose level increase suppression cosmetic product

摘要

PROBLEM TO BE SOLVED: To provide a drug, a food and drink, and a cosmetic which generate a blood glucose level-increase inhibitory effect using elastin-derived peptide.SOLUTION: The invention provides a blood glucose level elevation inhibitor, a food for inhibiting increase of blood glucose level, and a cosmetic for inhibiting increase of blood glucose level containing elastin-derived peptide. The elastin-derived peptide can be used suitably by chopping a meat containing elastin to undergo alkaline degradation, subsequently recovering an insoluble matter by filtration, and adding thermolysin and papain to this insoluble matter to degrade elastin. As a meat containing elastin, a bulbus arteriosus of fishes can be used suitably.
