摘要： 利用微波辅助萃取丝瓜籽油,采用单因素试验研究萃取溶剂石油醚与无水乙醇的混合比例、温度、时间、液料比对丝瓜籽油得率的影响,并在此基础上,通过Box-Behnken模型,设计4因素3水平响应面分析法,获得最佳工艺条件:石油醚与乙醇体积比2:1、温度51℃、时间14min、液料比10:1(mL:g),丝瓜籽油的得率为10.92%,与预测值基本一致。

关键词: 微波辅助萃取, 丝瓜籽油, 响应面法

Abstract: The optimum extraction conditions of microwave technology were studied for the luffa seed oil. The effects of the proportion of petroleum ether and anhydrous alcohol, temperature, time and liquid to material ratio on extraction rate of the oil in luffa seed were studied by single-factor experiments. On the base of single-factor experiments and three-level four-factor box-behnken design, the optimal conditions of microwave-assisted extraction were concluded as follows: the volume ratio of petroleum ether to anhydrous alcohol 2:1, temperature 51℃, time 14 min, liquid to material ratio 11 mL/g. In this condition, the actual luffa seed oil extraction rate was 10.92% which is almost equal to the predictable value.

Key words: microwave-assisted extraction, luffa seed oil, response surface methodology
