双酶法提取褐蘑菇水溶性膳食纤维研究

摘要

In order to provide theoretical basis for deep processing brown mushroom, dual enzymatic was used to prepare brown mushroom water-soluble dietary fiber. Materials ratio, enzyme treatment time and enzymolysis temperature were chosen as test factors to conduct the study. The results showed that the best extraction conditions to get water-soluble dietary fiber were liquid ratio 1 ： 10,enzyme treatment time 1.0 h, enzymolysis temperature 60℃. The yield rate was 36.1; under the best extraction conditions.%为了给褐蘑菇深加工提供理论依据，采用酶法制备褐蘑菇水溶性膳食纤维，选择物料比、酶处理时间、酶解温度作为试验因素进行研究。结果表明：酶法提取褐蘑菇水溶性膳食纤维的最佳提取条件为料液比1：10、酶处理时间1．0h、酶解温度60℃，此条件下水溶性膳食纤维产率为36．1％。
