In this study, solid state fermentation of mung beans by Cordyceps militaris SN-18 (C. militaris-fermented mung beans, CFMB) was performed. The effects of fermentation on phenolic content, antioxidant activity, and DNA damage protection of mung beans through various polarities solvent extracts were determined. Results showed that phenolic content, antioxidant activities, and DNA damage protection of mung beans were significantly enhanced by fermentation. The water extract of CFMB exhibited the highest phenolic content, DPPH radical scavenging activity, ferric reducing antioxidant power, reducing power, and DNA damage protection. During fermentation, shikimic acid, chlorogenic acid, vanillic acid, rutin, sinapic acid, and luteolin of mung beans were significantly increased. A clear correlation was found between phenolic content and antioxidant activity. Thus, CFMB with enhanced phenolic compounds, antioxidant activity, and DNA damage protection may be effective in the prevention of oxidative damage-induced disease, and it can serve as a novel nutraceutical and functional food in health promotion.
