摘　　要：探讨了木聚糖酶对玉米原料酒精发酵的影响。经优化后木聚糖酶的最适使用工艺为:木聚糖酶在发酵开始时加入,添加量为170U/g,料水比为1:2.5,初始pH值为自然。与对照组相比,原料出酒率提高5.93%,发酵周期缩短了12h,表明木聚糖酶对玉米原料酒精发酵有明显的促进作用。Application of xylanase in alcoholic fermentation by corn was investigated in this paper. The optimum parameters and technology were as follows： adding xylanase at the beginning of fermentation,by 170U/g, the ratios of material to water at 1：2.5, and with natural pH. Compared to fermentation without application of xylanase, the output rate of raw materials was increased by 5.93% and the fermentation period was shortened by 12 h. The results showed that the application of xylanase could significantly improve alcoholic fermentation.
