【摘要】 研究了超临界CO2萃取橘核油的优化方案,即萃取温度45℃、萃取压力25 MPa、CO2流量25L/h、萃取时间3h。在最优条件下,油脂得率为(11.34±0.84)%。采用气相色谱-质谱(GC-MS)联用技术对橘核脂肪酸组成进行了分析和鉴定,共分离鉴定出了10种脂肪酸,总不饱和脂肪酸为80.30%,其中主要成分为亚油酸和油酸,其相对含量分别为52.53%和26.40%。更多还原

【Abstract】 In this paper,the optimum extraction condition of Semen Citri Reticulatae oil by Supercritical CO2 was studied.The parameters such as extracting pressure,temperature,time and CO2 flow were obtained,they were 25 Mpa,45℃,3h and 25L/h respectively.The quantity of oil was 11.34%±0.84.The fatty acid composition in seed oil was separated and identified by GC-MC.They were ten fatty acids,total unsaturated fatty acids were 80.30%.Linoleic acid and Oleic acid were the chief components,and their relative contents were 52.53% and 26.40%.更多还原
