中文摘要: 以壶瓶枣为原料,利用响应面法对提取壶瓶枣多酚的工艺条件进行优化。在单因素试验基础上,选取提取温度、超声功率、液料比为自变量,根据Box-Behnken中心组合设计原理,采用三因素三水平试验设计,以多酚提取率为响应值进行响应面分析。运用Design-Expert 8.0.6软件对试验数据进行多元回归拟合。试验结果表明,壶瓶枣多酚最佳提取工艺条件为:液料比26∶1(mL/g)、超声功率200 W、提取温度68℃。在该工艺条件下,壶瓶枣多酚提取率可达4.35%,与预测值4.33%基本一致,为壶瓶枣资源的深度开发与综合利用提供了理论依据。
Abstract:The ultrasonic-assisted extraction process of polyphenols from Huping jujube was optimized using the response surface methodology(RSM).According to the experiment of single factor,the extraction temperature,ultrasonic power,ratio of liquid to solid,and their interaction on extraction rate of polyphenols was investigated by the Box-Behnken center composite design of RSM.The results showed that the optimum extraction conditions were as follow:the ratio of liquid to solid of 26∶1 (mL/g),ultrasonic power of 200 W,and extraction temperature 68℃.Under these conditions,the practical yield of polyphenols reached to 4.35%,which was consistent with to the predicted value of 4.33%.
