In the present study, soybean koji fermented with various GRAS filamentous fungi, including Aspergillus sojae BCRC 30103, Aspergillus oryzae BCRC 30222, Aspergillus awamori, Actinomucor taiwanensis and Rhizopus sp. These organisms are commonly used as starters in the fermentation of many traditional, oriental food products. The growth of starter organisms, total phenolic content, and antioxidative activities of the methanol extract of these kojis are compared with specific reference to alpha-diphenyl-2-picryl-hydrozyl (DPPH) radicals scavenging effects, Fe2+-chelating ability, and reducing power. 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-r...Continue Reading
