摘　　要：采用单因素试验和响应面优化试验相结合的方法对豆渣中多糖的提取工艺进行了优化。在单因素和响应面试验的基础上,通过试验数据建立起该提取过程的数学模型,同时进行方差分析,得到对应模型的回归方程,用该提取模型可以预测出最佳提取条件并进行验证,得出该提取过程的最佳工艺条件为:提取时间4.2 h、提取温度50℃、料液比1∶30 g·mL^(-1),最佳工艺条件下豆渣多糖的平均提取率为6.29%。The single factor experiment and response surface experiment were used to optimize the extraction process of polysaccharide from soybean residue.On the basis of single factor and the response surface experiments,the mathematical model of the extraction process was established through experimental data,then analysis of variance was carried out,the regression equation of the model was obtained.The optimal conditions of the extraction were as follows:the extraction time 4.2 h,the temperature 50℃,the ratio of material to liquid 1∶30 g·m L^(-1).Under above conditions,average extraction rate of polysaccharide from soybean residue was 6.29%.
