Study on sweet germinated brown rice wine rich in ferulic acid andγ-GABA
Sweet germinated brown rice wine rich in ferulic acid and γ-GABA was developed in this study. Germinated brown rice that has been pretreated was mixed with sweet wine koji for diastatic fermentation. The steam time of germinated brown rice, the amount of sweet wine koji, the fermentation temperature and the fermentation period were investigated. Results showed that germinated brown rice was steamed for 60 min, fermented with sweet wine koji at 31 ℃ for 60 h. The contents of ferulic acid and γ-aminobutyric acid of sweet germinated brown rice wine were 12.4 mg/100 mL and 2.1 mg/100 mL, respectively.
