摘要
以乙醇为溶剂,采用超声波辅助方法提取花生衣多酚。通过单因素试验,研究料液比、乙醇浓度、超声时间、超声温度等因素对多酚提取得率的影响,在此基础上通过正交试验对提取条件进行优化。结果表明:超声波法提取花生衣多酚物质的最佳条件为料液比1∶25、乙醇浓度55%、超声处理时间50 min、超声温度40℃,多酚提取得率为3 699μg/g。
The polyphenols were extracted from peanut skin by ultrasonic method with alcohol as extracting solvent. The effects of the ratio of stuff to solvent, concentration of ethanol, ultrasonic treatment time and ultrasonic treatment temperature on the extraction yield of polyphenols were obtained by single factor experiment, and optimized by orthogonal experiment. The optimal conditions of extraction were, solid - liquid ratio 1 ： 25, concentration of ethanol 55%, ultrasonic treatment time 50 min, ultrasonic treat- ment temperature 40 ℃, and the extraction rate of polyphenols was 3 699 p,g/g.
