摘要
本实验主要研究了超临界CO_2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-CO_2法对小白杏油脂进行萃取时,萃取压力为30MPa,萃取温度为30℃,CO_2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%。
The SCF-CO_2 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-CO_2 are determied as following: extraction press 30 MPa,temperature 35℃,extraction time3.0 h,CO_2 flow rate 15 to 20 kg/h,and using absolute C_2H_5OH as cosolvent with amount of 10% (accounting for the total raw material)."Xiaobai"apricot almond oil is rich in unsaturated fatty acids,especially oleic aci...
