摘要: 以苹果渣为原料,利用单因素实验和正交实验研究了可溶性膳食纤维和不溶性膳食纤维的提取工艺。本文是前一部分制备可溶性膳食纤维的实验。结果表明:提取可溶性膳食纤维A的最佳工艺条件是粒度40目、0.3%盐酸溶液、液料比15∶1(ml/g)、温度80℃时、反应2.0h;可溶性膳食纤维B的最佳工艺条件是8%NaOH溶液、液料比8∶1(ml/g)、温度90℃时、反应3.0h。

Abstract: Apple pomace was used as raw material to extract soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) with single factor experiments and orthogonal tests.SDF-A and SDF-B were prepared in this experiment.Results showed that the optimum conditions of SDF-A were as follows:with raw material 0.35mm diameter,3%hydrochloric acid,80℃,2.0h and liquid-to-solid ratio 15∶1(ml/g) .And the optimum conditions of SDF-B were as follows:with 8%sodium hydroxide,90℃,3.0h and liquid-to-solid ratio 8∶1(ml/g).
