摘　　要：糖化酶为糖苷键水解酶,根据淀粉水解原理,用糖化酶代替强酸对淀粉进行水解检测大曲淀粉含量。结果表明,酶水解法与酸水解法检测结果的差异性不显著,酶水解法在大曲淀粉检测上具有实用性。The saccharifying enzyme is a glycosidic bond hydrolase.According to the principles of starch hydrolysis,the saccharifying enzyme is used to hydrolyze the starch in Daqu instead of strong acid for the determination of starch content in Daqu.The results show that there is no significant difference between the enzymatic hydrolysis method and the acid hydrolysis method,which indicates that the enzymatic hydrolysis method is practical in the detection of starch in Daqu.
