【摘要】 进行了玉米免蒸煮生料酒精发酵试验,对影响其发酵的主要因素进行正交试验研究,结果表明:玉米生料酒精发酵在发酵剂添加量占原料的0.7%、料水比1∶4、起始pH 5.5、35°C条件下发酵4~5 d,原料淀粉利用率和酒精产率分别可达到81.4%和46.22%。更多还原

【Abstract】 Direct fermentation by using raw corn material to produce alcohol was investigated based on orthogonal experiments.The results showed that the optimum fermentation conditions were as follows: 0.7% for additive,1∶4 ratio(raw materials/water),pH 5.5 and 35°C for fermentation,4 to 5-day-fermentation duration.Under these optimum conditions,the starch utilizable percent reached 81.4%,while production of alcohol was 46.22%.更多还原
