摘 要：
【目的】优化超声辅助乙醇提取油茶籽饼多酚的工艺条件,为油茶多酚的提取、检测及利用提供技术参考。【方法】以油茶籽饼粉为原料、乙醇为提取液、超声波为辅助手段,采用单因素试验及正交试验设计,从超声强度、提取时间、提取温度、乙醇浓度及料液比等5个方面,对超声辅助乙醇提取油茶籽饼多酚工艺进行优化。【结果】综合考虑生产成本及提取效率,超声辅助乙醇提取油茶籽饼多酚的最佳工艺参数为:超声强度300W、提取时间0.5h、提取温度60℃、乙醇浓度40%、料液比1:15。【结论】在超声辅助乙醇提取油茶籽饼多酚的最佳工艺条件下,多酚提取率高达(2.987±0.141)%,说明超声辅助能提高乙醇对多酚的提取效率,是提取植物有效成分的高效辅助手段。
