摘　　要：研究以31.0%干物液化醪为原料,开展对糖化酶加量、尿素、酸性蛋白酶、pH值对发酵酒精度的影响。结果显示,糖化酶1.2 kg/t醪、尿素4.0 kg/t醪、酸性蛋白酶0.30 kg/t醪、pH4.5,发酵效果最优,酒精度可达15.82%vol。The effects of the adding levels of glucoamylase,urea,acid protease,and pH value on the fermented alcohol content were explored with 31.0%dry liquefied slurry as the raw material.The optimum technical parameters were summed up as follows:the adding levels of glucoamylase,urea acid and protease were 0.5 kg,4.0 kg and 0.30 kg per ton of grains,and pH was 4.5.Under the above conditions,alcohol content could reach up to 15.82%vol.
