摘要:

本实验主要研究了超临界CO2 萃取对新疆轮台小白杏杏仁油的工艺条件,并用气相色谱法对所得杏仁油的脂肪酸组成进行分析。结果表明,采用SCF-CO2 法对小白杏油脂进行萃取时,萃取压力为30MPa,萃取温度为30℃,CO2 流量为15~24L/h,萃取时间为3.0h,出油率可达57.4%;小白杏杏仁油主要由不饱和脂肪酸组成,小白杏杏仁油不饱和脂肪酸含量达到91.57%,其中主要油酸和亚油酸含量分别为40.89% 和49.87%。

Abstract:

The SCF-CO2 extraction process and GC analysis of fatty acid of “Xiaobai” apricot almond oil were investigated in this study. The results showed that the parameters for extracting apricot almond oil with SCF-CO2 are determied as following: extraction press 30 MPa, temperature 35 ℃, extraction time3.0 h, CO2 flow rate 15 to 20 kg/h, and using absolute C2H5OH as cosolvent with amount of 10% (accounting for the total raw material). “Xiaobai” apricot almond oil is rich in unsaturated fatty acids, especially oleic acid and linoleic acid,accounting for 91.65% and 91.75%, respectively.

Key words: “Xiaobai&rdquo, apricot almond oil, supercritical fluid-CO2 extraction, fatty acid
