시판 식해의 건강 기능 특성

초록

Sik-hae is a traditional Korean salt-fermented seafood having a low salt content and a high concentration of Lactobacillus, unlike most salt-fermented fish and fish sauce, which have a high salt content and low concentration of Lactobacillus. This study aimed to investigate the health-promoting functional properties of 10 types of commercial sik-haes. The results showed that for the commercial sik-haes studied, angiotensin-I-converting enzyme inhibitory activity, DPPH radical scavenging activity, α-glucosidase inhibitory activity, xanthine oxidase inhibitory activity, and sodium nitrite scavenging activity ranged from 29.0% to 46.3%, 35.5% to 65.4%, 0% to 20.0%, 20.1% to 78.8% , and 17.9% to 82.6%, respectively. Antimicrobial activity against Escherichia coli, Vibrio parahaemolyticus and Staphylococcus aureus was rarely detected. The results on healthy functional properties suggest that the commercial sik-haes are expected on the antioxidative activity in F-1–F-5, AP-1, BES, and S, xanthine oxidase inhibitory activity in the other 9 types expected for A, and sodium nitrite scavenging activity in the other 9 types expected for AP-2.
