摘　　要：采用超声波辅助碱法提取蕨菜中的水溶性膳食纤维(SDF),通过单因素试验探讨料液比、超声功率、碱液质量浓度、提取温度4个因素对SDF得率的影响,再通过正交试验对提取工艺条件进行优化。结果表明,超声波辅助碱法提取蕨菜中的SDF最佳工艺条件为氢氧化钠质量浓度0.06 g/mL,超声功率120 W,料液比1∶30(g∶mL),提取温度65℃,实际测得SDF得率为36.01%。Ultrasonic-assisted alkaline method is applied to extract soluble dietary fiber （SDF） from Pteridium aquilinum,. Four independent variables including material-liquid ratio, ultrasound power, alkali concentration and extraction temperature are chosen with respect to the dependent variable SDF yield for single-factor experiments. Then the extraction technology of SDF from Pteridium aquilinum is optimized by using an orthogonal experiment. The results show that the optimal process conditions are alkali concentration 0.06 g/mL, ultrasound power 120 W, material-liquid ratio 1：30 （g · mL） , extraction temperature 65 ℃ , under these conditions, the yield of SDF is 36.01%.
