摘　　要：以榆黄蘑为原料,采用碱法提取榆黄蘑中可溶性膳食纤维,研究碱液质量浓度、料液比、提取时间和提取温度对可溶性膳食纤维得率的影响,通过正交试验优化出的最佳提取工艺条件为碱液质量浓度2 g/100 mL,料液比1∶25,提取时间80 min,提取温度70℃。在此条件下,榆黄蘑可溶性膳食纤维得率达到15.03%。The extraction technology of soluble dietary fiber from Pleurotus citrinopileatus by alkaline hydrolysis was investigated in this paper. The effects of alkali concentration,the ratio of solid to liquid,extraction time,and extraction temperature on the soluble dietary fiber yield were studied. The optimal extraction technology was obtained by orthogonal methodology as follows:alkali concentration 2 g/100 mL,the ratio of solid to liquid 1∶25,extraction time 80 min,extraction temperature 70 ℃,by which the yield of obtained dietary fiber was 15.03%.
