ANGIOTENSIN CONVERTING ENZYME INHIBITORS

摘要

the object of the present invention is to provide a peptide having angiotensin converting enzyme inhibitory activity also improved in the taste, and to provide a method of producing an angiotensin converting enzyme inhibitors comprising at least one of such enzymes. Another object of the present invention is to provide an antihypertensive comprising a peptide having angiotensin converting enzyme inhibitory activity. Thus, the present invention is any of the five peptides represented by the following formula (1) to (5) and the salts thereof, soybean protein hydrolysates containing these peptides and the method of producing these peptides or the salts thereof comprising hydrolyzing soybean proteins with protease D3:(1)Tyr-Val-Val-Phe-Lys; (2)Pro-Asn-Asn-Lys-Pro-Phe-Gln; (3)Asn-Trp-Gly-Pro-Leu-Val; (4)lle-Pro-Pro-Gly-Val-Pro-Tyr-Trp-Thr; (5)Thr-Pro-Arg-Val-Phe.
