Antioxidant properties of fermented soybean broth

摘要

Soybean broth (SB) and fermented soybean broth (FSB), at 100/100 exhibited good antioxidant activities of 0.85 and 0.80, respectively. Only FSB echibited an excellent reducting power of 0.76-0.86 at 5-100/100. FSB showed an excellent scavenging activity on 1,1-diphenyl-2-picrylhydracyl (100/100) at 20-100/100, while SB only at 20/100 inhibited the production of superoxide anion radicals by 81-93/100 but SB showed no inhibition/
