摘　　要： 对以豆渣为原料制备不溶性膳食纤维过程中的脱脂工艺进行了研究。应用正交试验设计,以脱脂率和膳食纤维得率为考察指标,对碱法和碱性脂肪酶法两种工艺条件进行优化并加以比较。结果表明:碱法脱脂最优工艺条件下脱脂率97.13%,膳食纤维得率58.37%;碱性脂肪酶法脱脂最优工艺条件下脱脂率82.20%,膳食纤维得率69.65%。 Defatting technology was studied during the preparation of insoluble dietary fiber （IDF）from soybean residue. The technologies of alkaline defatting and lipase hydrolysis defatting were compared by investigating the defatting rate and the yield of IDF. Optimum conditions for each defatting method was determined by orthogonal test. Under the optimum conditions of alkaline defatting, the defatting rate was 97.13%, and the yield of IDF was 58.37%. Moreover, the defatting rate was 82.20%, and the yield of IDF was 69.65 % under the optimum conditions of lipase hydrolysis defatting.
