摘要
为提高苦荞米中淀粉的转化率和苦荞发酵酒的酒精度,以苦荞米为原料,考察了苦荞发酵酒糖化工艺中的糖化酶添加量、时间、温度、pH对还原糖含量和酒精度的影响。然后利用正交优化糖化工艺条件。结果表明,糖化最优的工艺参数为:糖化酶添加量1.0%,时间为90 min,温度为70℃,pH为4.0。
With buckwheat rice as raw material, the effects of the of glucoamylase addition, time, temperature, pH value for reducing sugars and alcoholic slrength in saccharification technology was studied to improve the conversion of buckwheat rice starch and buckwheat fermented wine alcohol. Orthogonal design was adopted to optimize the saccharification conditions. The results showed that optimal technical conditions were as follows： glucoamylase addition 1.0%, time 90 min, temperature under 70 % and pH 4.0.
