摘　　要：在玉米酒精生产中,利用耐高温酒精活性干酵母进行酒精发酵实验,确定发酵温度、发酵液初始pH、酵母添加量、发酵时间对酒精发酵的影响,然后进行正交实验,确定最佳工艺条件为发酵温度37℃,发酵液初始pH为5.0,酵母添加量为1.2‰,发酵时间48h。发酵残液中酒精浓度9.96%。In the proceed of maize alcohol, tlie influence of the temperature, pH, the quantity of the yeast and the time of fermentation were determined when the temperature tolerant active dry yeast was used in the experiment. The orthogonal experiment was followed. The optimum conditions of fermentation were gained： fermentation temperature si 37℃, pH of the liquid is5.0, the quantity of the yeast is 1.2‰ and the time of fermentation is 48h.The concentration of alcohol in the fermentation liquid is 9.96%.
