| 摘 要： | 以小麦麸皮为原料,采用酶化学方法制备膳食纤维,通过正交实验得出不可溶膳食纤维的最佳提取条件:α-淀粉酶的用量为0.4%,酶解时间为40 min,碱解浓度为4%,碱解时间为45 min;在此条件下,不可溶膳食纤维得率为32.56%;初步探索了可溶性膳食纤维制备工艺,最终可溶性膳食纤维得率为9.90%.

| Abstract: | The technology for extracting the insoluble dietary fiber and soluble dietary fiber from wheat bran by the combined chemical and enzyme method was studied.The optimal insoluble dietary fiber extracting conditions is:0.4% α-amylase for 20 min and 4% NaOH for 45 min.Under this condition,the extracting rate of insoluble dietary fiber is about 32.56%;the extracting rate of soluble dietary fiber is about 9.90%. |
