为了提高水相酶法油脂提取率,研究采用超声辅助提取油茶籽油及水解蛋白。应用Plackett-Burman设计联用响应面分析法对超声辅助水相酶法提取油茶籽油和水解蛋白的工艺进行优化。首先用Plackett - Burman设计试验筛选出具有显著效应的3个因素——超声时间、pH和反应时间;然后采用响应面分析法确定主要影响因素的最优工艺条件为超声时间30 min、pH 9和反应时间3.5 h,在此条件下,油茶籽油得率为89.704%,油茶籽蛋白得率为90.638%,与预测值误差不超过0.5%。这表明Plackett - Burman设计联用响应面分析法建立的模型具有可行性。

Ultrasound-assisted extraction of oil and hydrolyzed protein from camellia was studied in order to improve oil extraction by aqueous enzymatic. Ultrasound-assisted aqueous enzymatic extraction of oil and protein from camellia was optimized by Plackett Burman design combined with response surface methodology. Firstly, ultrasonic time, pH, response time were identified by Plackett-Burman design as the significant factors, then the extraction conditions were optimized by response surface analysis as follows. ultrasonic time 30 min, pH9 and respons...
