摘　　要：采用超声波辅助Na_(2)CO_(3)浸提锥栗壳色素,先开展单因素试验,再选择超声时间、超声温度、超声功率为自变量,提取率为响应值,选用Box-behnken设计并进行响应曲面分析,进一步探索各因素及其交互作用对锥栗壳色素提取的影响,最后获得回归方程的预测模型。结果表明,锥栗壳色素最佳提取工艺参数为超声时间47.2 min,超声温度81.39℃,超声功率450 W,此工艺条件理论预测值(39.18%)与修正工艺后的验证结果(38.41%)间的相对误差约为0.77%,说明该模型合理,对指导实践有一定作用。Ultrasonic wave aided with Na_(2)CO_(3) was adopted to digest and extract the pigment of chestnut shell.Single factor experiment was firstly carried out,and then ultrasonic extraction time,ultrasonic temperature and ultrasonic power were chosen as the independent variables,with the extraction ratio as the response value.In addition,Box-behnken design was applied for response surface analysis,to further explore the influence of various factors and their reciprocal action on the extraction of pigment of chestnut shell,thus finally obtaining the prediction model of regression equation.The results suggested that the optimum extraction process parameters of the pigment of chestnut shell were 47 min of extraction duration,82℃of ultrasonic temperature and 450 W of ultrasonic power.The relative difference between the theoretical predicted value under the process conditions(39.18%)and verified result after modification process(38.41%)was approximate to 0.77%,suggesting that the model was rational and bears certain significance in guiding the practice.
