为优化稻壳多糖超声辅助酶提取工艺，在单因素实验基础上，选取超声温度、超声时间及纤维素酶添加量为自变量，多糖提取率为响应值，采用中心组合设计的方法，研究各自变量及其交互作用对多糖提取率的影响。利用响应面分析方法，模拟得到二次多项式回归方程的预测模型，并确定稻壳多糖提取工艺的最佳条件：超声作用温度48℃、超声作用时间42 min、纤维素酶添加量1.06%，在此条件下，多糖提取率为0.948%。

In order to optimize ultrasonic-assisted enzyme extraction for polysaccharides from rice hull,a mathematical regression model for predicting extraction yield of polysaccharides as a function of ration of independent variables,including extraction temperature,extraction time and cellulase addition amount was established by fitting central composite design experimental results and interactive effects of the independent variables on extraction yield of polysaccharides were investigated by response surface methodology based on the analysis of single-factor experiments. The optimum extraction conditions as follows:extraction temperature 48℃,extraction time 42 min,cellulase addition amount 1.06%. Under the optimal extraction conditions,the maximum yield of polysaccharide was 0.948%.
