采用响应面法对微波辅助提取燕麦多酚的工艺进行优化,并与传统热水提取方法进行对比.结果显示:微波辅助提取燕麦多酚的最佳工艺参数为:微波功率100W,时间125 s,料液比1:45,乙醇体积分数50%,此条件下燕麦多酚得率为107.46mg/100 g;与传统热水提取方法相比,微波辅助法提高燕麦多酚得率在55%以上,尤其是燕麦生物碱Bc、Bp、Bf的含量极显著提高(P<0.01),提取时间缩短了60倍.
Optimization of Microwave-assisted Extraction of Oat Polyphenols by Response Surface Method
Response surface method was applied to optimize the microwave-assisted extraction conditions of oat polyphenols, and a comparison was made between traditional hot water extraction and microwave-assisted extraction. The results showed that the optimum microwave-assisted extraction conditions were as follows: microwave power 1 000 W, microwave time 125s, the ratio of solid to liquid 1:45, ethanol concentration 50%. And the yield of oat polyphenols was 107.46 mg/100 g. By comparison with traditional hot water extraction method, microwave-assisted extraction method enhanced the yield of oat polyphenols by more than 55%, especially the contents of Be, Bp and Bf were raised extremely significantly (p<0.01), meanwhile the extraction time was 60 times shorter.
