摘要
对以橡实淀粉为原料生料发酵生产燃料酒精的工艺条件进行了研究。结果表明:采用超声波助提法可有效脱除单宁,提高橡实淀粉的燃料酒精转化率。单因素试验和正交试验得出的橡实淀粉生料发酵最佳工艺参数为料水比16∶10,α-淀粉酶50 U/g,糖化酶190 U/g,发酵温度25℃,发酵时间7 d。
The author studied the production technology of fuel ethanol through fermentation of uncooked materi- al, of which raw material was acorn starch; The results showed that the extraetation method by ultrasonic wave could improve the ratio of tannin removal. The optimal fermentation conditions were summed up through single factor tests and orthogonal tests as follows： the material -to -water ratio as 16： 10, α -amylase as 50 U/g, glucoamylase as 190 U/g, fermentation temperature as 25 ℃, fermentation time as 7 d.
