摘要
以不同品种的大麦为材料,运用底物分析法检测三种淀粉酶的活性。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,浸麦可在一定程度上抑制淀粉酶的活力;淀粉酶的总活力在发芽初期缓慢增加,2～3d后急剧增加至最大值;焙焦可使三种酶酶活有不同程度的下降。
Based on different species of barley,the foot layer analytic method was used to examine the activity of three carbohydrases. In material and kilned barley from different varieties, the difference between the activity of α-amylase,β-amylase and limit dextrinase was great.During barley malt production, steeping the barely seeds depressed the activity of the carbohydrases.The activity of the carbohydrases increased slowly in the beginning ui the germination course, and rapidly in 2-3d. Kilning decreased the activity of three carbohydrases in diffierent degree.
