Antihypertensive effect of peptide-enriched soy sauce-like seasoning and identification of its angiotensin I-converting enzyme inhibitory substances.

We have developed a peptide-enriched soy sauce-like seasoning termed Fermented Soybean Seasoning (FSS), by modifying the process of soy sauce brewing. The FSS has a 2.7-fold higher concentration of total peptides than regular soy sauce. The angiotensin I-converting enzyme (ACE) inhibitory activity of FSS (IC(50) = 454 microg/mL) was greater than that of… CONTINUE READING
