摘　　要：采用响应面法优化超声波对提取酒精糟中色素的工艺条件进行了研究。在单因素试验的基础上，选取超声时间、固液比和超声波功率为关键因子，应用Box—Behnken中心组合进行3因素3水平的实验设计，以色素收率作为响应值，进行响应面分析（RSA）。结果表明，超声波法提取酒糟中玉米黄色素的最佳提取条件为：提取时间69．85min，超声功率744W，固液比1：4．5（g：mL），提取率预测值137ug／g，验证值为132ug／g，与预测值的相对误差为3．8％。The response surface analysis methodology （RSM） was used for optimizing ultrasonic assisted extraction conditions in the extraction process of maize yellow pigments. Based on the single-factor experiments, three independent variables including extracting time, water-solid ratio and ultrasonic power, were selected as casual factors during extraction. The experiments were arranged according to Box-Behnken central composite experiment design. Response surface analysis method was applied to determine the effect of central composite experiment design. Response surface analysis method was applied to determine the effect of casual factors on the yield of maize yellow pigment. The results showed that the optimal ultrasonic extraction conditions for maize yellow pigment was as follows： extraction time 69.85 min, ultrasonic power 744W and ratio of solid to water 1：4.5 （g/mL）. The predictive extraction rate was137ug/g, and the actual extraction rate was 132 ug/g, the relative error being 3.8%.
