微波辅助提取番石榴多酚的研究

Study on microwave assisted extraction of polyphenols from guava

采用微波辅助提取法提取番石榴多酚。在单因素实验基础上,用响应面法优化提取工艺。通过JMP软件对数据进行分析,结果表明:微波辅助提取番石榴多酚的最佳工艺条件为微波功率490W,料液比1∶21(m∶v),乙醇浓度50%,提取时间130s,在此条件下番石榴多酚提取率可达到(1.78±0.38)mg/g。

The microware assisted extraction was used on the extraction of polyphenols from guava in this paper. On the basis of single factor experiments,the response surface methodology was used to optimize the technological condition. The data analysis showed the best technological condition of microware assisted extraction were as follows.microware power was 490W,ethanol concentration was 50%,solid to liquid ratio was 1：21 （m/v）,extraction time was 130s. Under this technological condition,the yield was （1.78±0.38）mg/g.
