摘要
本研究将中温淀粉酶和高温淀粉酶结合使用制备糊精。通过正交试验确定了比较适宜的水解参数为温度90℃,时间10min,中温淀粉酶用量4U/g淀粉,高温淀粉酶用量7U/g淀粉;两种淀粉酶的结合使用可以降低酶的用量和缩短酶解反应时间。
Dextrin were prepared by the combined use of α-medium temperature amylase and α-high temperature amylase. The results showed that the optimal preparation conditions of low-dextrose equivalent （DE） value dextrin are determined as follows： temperature 90 ℃, hydrolysis time 20 re.in, dosage of medium temperature α-amylase 4 U/g starch and dosage of or-high temperature α-amylase 7U/g starch. The combined use of the two kinds of α-amylase can decrease the dosage of amylase and hydrolysis time.
