摘要
在料水比为１∶２．８～３．２的酒精浓醪发酵中，添加适量的酸性蛋白酶，可缩短发酵周期至４８ｈ，其原料出酒率为３２．５１％，比对照提高约１．０４％，吨酒精可节省玉米用量１０２ｋｇ，成本降低约９１．８元。
The right amount of acid proteinase was added into the heavier mash for alcohol fermentation according to the ratio of material to water=1∶2.8～3.2.Thus the fermentation period was reduced to 48h.The yield of liquor was 32.51%.It was increased about 1.04% than that of normal fementation.The consumption of maize economized 102kg per ton alcohol.The cost was reduced about 91.8 yuan and economic benefit was obvious.
