摘　　要：用复合酶法提高豆渣中膳食纤维的提取率。研究酶制剂配比(α-淀粉酶∶木瓜蛋白酶)、酶制剂用量、酶解时间和pH值4个因素对膳食纤维提取率的影响。由单因素试验结果可知,酶制剂配比、用量和酶解时间对膳食纤维提取率的影响较大,正交试验结果表明:在酶制剂配比为1∶3(m∶m)、用量为1%、酶解时间为2h时,脱脂豆渣中膳食纤维的提取率最高,达83.84%,即原豆渣中膳食纤维提取率为76.89%。Used complex enzyme to improve the extraction rate of dietary fiber from soybean dregs. The ratio of complex enzyme （α-am ylase ： papain）, the additive amount of complex enzyme, the enzymolysis time and pH were researched. It was showed that the ratio, the additive amount and the enzymolysis time had a great influence on extraction rate. With the three factors in L9 （34） orthogonal experimental design, the results showed that the ratio 1 ： 3, the additive amount 1% and the enzymolysis time 2 hours were the optimal conditions for enzymolysis. The extraction rate of defatted dietary fiber was 83.84%, and the extraction rate in soybean dietary fiber was 76.89%.
