响应曲面法优化原花青素的超声波协同微波提取工艺

摘要

The ultrasonic-microwave synergistic extraction (UMSE) parameters of anthocyanins were optimized. The effects of UMSE and other extraction techniques were compared.The result showed that the best condition for UMSE were; ethanol concentration 67.4% , extract time 192 s, microwave power 478 W, the extraction yield was 3. 920% . Compared with other extraction techniques, UMSE had higher extraction yield and shorter extraction time.%文中研究了超声波协同微波提取原花青素的最佳工艺参数,并与其他提取方法进行了对比.结果表明:超声波协同微波提取原花青素的最佳工艺参数为,乙醇体积分数67.4%、提取时间192 s和微波功率478 W,此时原花青素得率为3.920%;与其他提取方法相比,超声波协同微波提取时间短,得率高.
