摘要
对小麦淀粉清液生料发酵酒精工艺中的关键问题进行研究,结果表明,采用超级酿酒高活性干酵母菌种,小麦淀粉清液浓度为22%,每200mL清液中添加0.18g糖化酶,35℃发酵,小麦淀粉生料发酵的酒精度较高、残余淀粉量少,并可有效改善传统蒸煮发酵引起的粘度高过滤困难等问题。
The critical problems in alcohol fermentation by uncooked wheat flour clear liquid were studied.The results indicated that higher alcoholicity and less residual starch could be realized as Angel super alcohol active dry yeast was used,the concentration of wheat flour clear liquid was 22 %,0.18 g glucoamylase was added in per 200 mL clear liquid,and the fermentation temperature was controlled at 35 ℃.The above methods could effectively settle the problems of high viscosity and difficult filtering induced by traditional cooking steaming fermentation.
