Patent number: 9060538Abstract: The present invention provides soy sauce that comprises significant amounts of peptides, and, in particular, hypotensive peptide Gly-Tyr and hypotensive peptide Ser-Tyr, exhibiting a high degree of angiotensin-I-converting enzyme-inhibitory activity and has hypotensive effects while containing no hypotensive agent. Target soy sauce is obtained by mixing soy sauce koji having protease activity of 20 to 300 U/g koji with an aqueous common salt solution and subjecting the mixture to heated digestion, followed by compression filtration. Target soy sauce with a good flavor is obtained by adding soy sauce lactic acid bacteria and soy sauce yeast cells to the moromi mash after heated digestion, and subjecting the resultant to fermentation and maturation, followed by compression filtration.Type: GrantFiled: December 24, 2010Date of Patent: June 23, 2015Assignee: KIKKOMAN CORPORATIONInventors: Yoshikazu Endo, Shigeki Tanizawa, Takeharu Nakahara, Hitomi Aota, Hiroki Ono, Yoichi Hanada, Riichiro Uchida

Patent number: 8691302Abstract: A fermented seasoning which does not have the bitterness specific to peptides and can be easily ingested orally, in spite of containing large amount of peptides is provided. Namely, a fermented seasoning obtained by adding salt water to an Aspergillus culture or a mixture of the Aspergillus culture with a plant-derived protein material and by controlling the leucine aminopeptidase-I activity in the moromi to be 1.0 U/ml or less, and also controlling the leucine aminopeptidase-II activity in the moromi to be 0.5 U/ml or less, within 10 days after the preparation.Type: GrantFiled: July 2, 2009Date of Patent: April 8, 2014Assignee: Kikkoman CorporationInventors: Takeharu Nakahara, Riichiro Uchida, Yoichi Hanada, Yoshikazu Endo, Shigeki Tanizawa, Hitomi Aota, Seiichi Hara
