摘　　要： 以蚕豆渣为原料,通过单因素试验和L9(34)正交试验得出用碱法和酶-碱法提取水不溶性膳食纤维的最佳工艺条件,并测定了2种方法制取的水不溶性膳食纤维的溶胀性和持水性。结果表明,碱法最佳工艺条件为:NaOH溶液浓度6g/100mL,碱浸温度50℃,碱浸时间40min;酶-碱法最佳工艺条件为:NaOH溶液浓度3g/100mL,碱浸温度60℃,碱浸时间50min,胰蛋白酶用量0.4g/100mL。酶-碱法制取的水不溶性膳食纤维具有较好的溶胀性和持水性。 The optimum conditions for preparation of water-insoluble dietary fiber from broad bean dregs using alkali dissolution and enzyme chemistry dissolution were obtained through single factor experiment and L9(34)orthogonal experiment.The swelling behavior and water-binding capacity of the dietary fiber were also determined.The results showed that the optimum conditions of alkali dissolution were NaOH(6 g/100 mL),temperature(50 ℃),time(40 min),and that the optimum conditions of enzyme-chemistry dissolution were NaOH(6 g/100 mL),trypsin(0.4 g/100 mL),soaking temperature(60 ℃) and soaking time(50 min).The water-insoluble dietary fiber prepared by enzyme-chemistry dissolution was found to feature in better swelling behavior and water-binding capacity.
