Chinese rice wine, produced by simultaneous saccharification and fermentation (SSF), has an uneconomic, time consuming and environment-unfriendly pretreatment.
In this study, an enzymatic extrusion pretreatment was applied to manufacture Chinese rice wine. Response surface methodology (RSM) was used to investigate the effect of process parameters namely barrel temperature (BT), moisture content(MC), and a-amylase concentration (AC) on the alcoholic degree of rice wine.
