ANGIOTENSIN-CONVERTING ENZYME INHIBITOR PEPTIDE CONTAINING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a composition containing an ACE inhibitor peptide which inhibits ACE effectively through intake of a small amount, has no possibility of side effects and allows hypertensive persons to ingest easily in daily life.SOLUTION: A composition containing an ACE inhibitor peptide contains a tripeptide Asp-Arg-Pro which is prepared by hydrolyzing a protein source with a solid koji culture and has an angiotensin-converting enzyme inhibiting activity in concentration of 47-154μg/ml. Alternatively, a composition containing an ACE inhibitor peptide contains a tripeptide Gly-Val-Pro which is prepared by hydrolyzing a protein source with a solid koji culture in a concentration of 21-56μg/ml.
