利用微波萃取丝瓜籽油,考察最佳工艺条件。采用正交设计研究温度、时间、料液比和无水乙醇与石油醚体积比对丝瓜籽油提取率的影响。结果表明,影响丝瓜籽油提取率的因素的主次顺序为:溶剂体积比>料液比>温度>时间;最佳工艺参数:无水乙醇∶石油醚为1∶2(V/V)、温度55℃、时间14 min、料液比1∶11(m/V),丝瓜籽油最大提取率为10.90%。
Microwave extraction of loofah oil, study the best conditions. The orthogonal design was used to study the effects of temperature, time, solid-to-liquid ratio and volume ratio of absolute ethanol to petroleum ether on the extraction rate of loofah oil. The results showed that the main order of the factors affecting the extraction rate of loofah oil was solvent volume ratio> solid-liquid ratio> temperature> time. The optimum process parameters were as follows: anhydrous ethanol: petroleum ether 1: 2 (V / V) Temperature 55 ℃, time 14 min, the ratio of material to liquid 1:11 (m / V), the maximum extraction rate of loofah oil was 10.90%.
