| 摘 要： | 应用超临界CO2萃取技术提取了黄瓜籽油。采用正交试验,考察了萃取压力、萃取温度、萃取时间及CO2流量对黄瓜籽油收率的影响。利用GC-MS分析了所得黄瓜籽油的脂肪酸组成。结果表明:影响黄瓜籽油收率的顺序为萃取压力>萃取温度>萃取时间>CO2流量;最佳萃取条件为压力35 MPa,温度35℃,时间120min,CO2流量45 L/min,在此条件下出油率可达26%。黄瓜籽油中含有4种脂肪酸,亚油酸含量高达77.81%。

| Abstract: | The supercritical CO2 fluid was applied in extracting oil from cucumber seed.The effects of extraction pressure,temperature,time and CO2 flow on the oil extraction efficiency were investigated by orthogonal experiments.The fatty acid composition of cucumber seed oil was analyzed by GC-MS.The results showed that the significance of the effects of these factors on the oil extraction efficiency were in the order of: extraction pressure,temperature,time and CO2 flow.The maximum extraction efficiency of cucumber seed oil could reach to 26% under the extraction pressure of 35MPa,35℃,for 120min at CO2 flow 45L/min.The cucumber seed oil has four fatty acids,the linoleic acid content is up to 77.81%. |
