Enhanced antioxidative activity of soybean koji

 Posted by Chantel M. Contributed by US National Library of Medicine National Institutes of Health


In the study to evaluate the soybean koji fermented with various GRAS filamentous fungi, including Aspergillus sojae BCRC 30103, Aspergillus oryzae BCRC 30222, Aspergillus awamori, Actinomucor taiwanensis and Rhizopus sp,  posted in US National Library of Medicine National Institutes of Health, showed that depending on starter organism, various extents of mycelia propagation (35.23-86.29 mg/g koji) were noted after 3 days of fermentation. Total phenolic content increased in soybean after fermentation. Koji also displayed enhanced antioxidative activates in comparison with the non-fermented soybean. Among the five kinds of koji tested, those fermented with Asp. awamori exhibited the highest levels of DPPH-free radicals scavenging activity, Fe2+-chelating ability and reducing power. The DPPH-free radicals scavenging activity and Fe2+-chelating ability of this soybean koji was ca. 8.9 and 6.7 fold that of the control. Analysis of the dose-response effect also revealed that before reaching a threshold point, there is a linear relationship between increases in antioxidative activity and increases in the concentration of the koji extract.
