摘要
探讨石榴皮加工副产品综合利用的基础因子。采用超声波-微波协同提取技术提取石榴皮中多酚类物质,研究了乙醇体积分数、料液比、微波功率、超声波功率、提取时间、浸提次数对石榴皮多酚提取得率的影响,并在单因素试验基础上进行正交试验,确定其较佳提取工艺为:以料液比1∶30 (g/mL)加入60%乙醇溶液浸泡20min后,在微波功率250W、超声波功率500W条件下提取1min,石榴皮多酚提取得率为(28.78±0.12)%,提高了提取效率。
The basic factors of comprehensive utilization of by-products of pomegranate peel processing are discussed.Ultrasonic-microwave assisted extraction technology is used to extract polyphenols from pomegranate peel,the effects of ethanol volume fraction,solid-liquid ratio,microwave power,ultrasonic power,extraction time and extraction times on the extraction rate of polyphenols from pomegranate peel are studied,orthogonal test is conducted on the basis of single factor test to determine the best extraction process:after soaking in 60%ethanol solution with the solid-liquid ratio of 1∶30(g/mL)for 20 min and extracting for 1 min at microwave power of 250 W and ultrasonic power of 500 W,the extraction rate of polyphenols from pomegranate peel is(28.78±0.12)%,which has improved the extraction efficiency.
