摘　　要：以常山胡柚鲜果为原料,采用乙醇沉淀-化学法对果实中果皮内可溶性膳食纤维的提取工艺进行优化,以期获得提取的最佳工艺及其参数条件,为日后更好地开发利用提供理论依据。通过单因素试验及L_(9)(3^(4))正交试验后得知:影响常山胡柚SDF提取得率的主次因素顺序为料液比>酸解时间>酸解温度>提取液p H;其最佳的提取工艺条件为料液比1∶20(g/mL)、提取液pH 2、酸解温度80℃、酸解时间60 min。所得结果可为日后的进一步推广应用提供参考。This paper taked fresh fruits of Changshan-huyou as test materials,adoptting ethanol precipitation and chemical combination method to optimize on extraction process of soluble dietary fiber in Changshan-huyou middle peel,in order to achieve the optimum conditions of extraction process and to provide the theoric according for better developing and using after today.Carrying out the single factor experiment and L_(9)(3^(4))orthogonal experiment on the four factors,the results showed that the order of influence factors on productivity of Changshan-huyou SDF was material liquid ratio>acid hydrolysis time>acid hydrolysis temperature>p H;The optimum conditions of extraction process were material liquid ratio 1∶20(g/mL),pH 2,acid hydrolysis temperature 80℃and acid hydrolysis time 60 min.This result might provide refer for better using after today.
