摘要 以不同品种的大麦为材料,运用底物分析法检测3种淀粉酶的活性。不同品种的大麦中α-淀粉酶、β-淀粉酶和极限糊精酶活力差异较大,因此实际生产中可对不同品种大麦进行筛选,选用酶活较高的大麦来制备麦芽;在制麦过程中,浸麦可在一定程度卜抑制淀粉酶的活力;淀粉酶的总活力在发芽初期缓慢增加,2d~3d后急剧增加至最大值;焙焦可使3种酶酶活有不同程度地下降。 Using different species of barley as material, the activities of three amylase were determined by the substrate analysis method. It was found that there were significant differences in the activities of α-amylase, β-amylase and limit dextrinase in different barley. The barley contained higher activity should be selected to produce malt. During malt production, the activity of the amylase was inhibited. The activity of the amylase slowly increased in the beginning of the germination course and rapidly enhanced after 2 -3d. Kilning could decrease the activities of three amylase to some extent.
