中文摘要: 以沅江芦笋为原料,通过超声辅助酶法提取可溶性膳食纤维,探讨α-淀粉酶与糖化酶质量比、浸提时间、超声功率、超声温度以及料液比对可溶性膳食纤维提取得率的影响,并采用正交试验优化可溶性膳食纤维最佳提取工艺。结果表明,最佳提取工艺条件为料液比1∶200(g/mL),α-淀粉酶与糖化酶质量比5∶5,浸提时间4 h。在该工艺条件下沅江芦笋可溶性膳食纤维提取得率为16.77%。
Abstract:The soluble dietary fiber was extracted from Miscanthus lutarioriparius by the ultrasound-assisted enzymatic extraction method.The effects of α-amylase and glucoamylase addition ratio,extraction time,ultrasonic power,ultrasonic temperature,and solid-to-liquid ratio on the yield of soluble dietary fiber were studied.The extraction process was optimized by the orthogonal test. The results showed that the optimum extraction conditions were as follows:the solid-to-liquid ratio of 1∶200(g/mL),the α-amylase-to-glucoamylase ratio of 5∶5,and extraction time of 4 h.Under these conditions,the yield of soluble dietary fiber extracted from M.lutarioriparius reached 16.77%.
