| 摘 要： | 以甜高粱茎汁为原料,采用耐高温活性干酵母对其进行发酵生产酒精。当甜高粱茎汁液糖浓度为28.0g·100mL-1,以酒精得率为指标,通过设计正交试验确定甜高粱茎汁中营养盐的最适添加量为(NH4)2HPO40.20%、MgSO40.10%、CaCl20.10%。在此条件下进行发酵,酒精得率可达到93.0%,酒精度可达14.1%(v/v)。

| Abstract: | Alcohol with sweet sorghum stalk juice as raw material was fermented by angel high-temperature dry-alcohol yeast in this paper. The optimum conditions of alcohol fermentation were determined by orthogonal test and the experimental index was as follow: (NH4)2HPO4 0.20% , MgSO4 0.10% , CaCl2 0.10% . The sweet sorghum stalk juice was adjusted 28.0 g·100 mL-1, and under the suitable condition, fermentation rate was 93.0%, alcohol degree was 14.1%(v/v). |
