摘要:

对超临界CO2萃取沙棘籽油及热敏性物质进行分析研究。通过正交试验确定最佳工艺条件:萃取压力25MPa、萃取温度40℃、CO2流量18kg/h、萃取时间120min、分离压力8MPa,在此工艺条件下沙棘籽油出油率为52%。高效液相色谱法检测沙棘籽油中α-VE含量为2.6%,经超临界CO2萃取后热敏性物质α-VE损失3.7%,胡萝卜素含量为100850μg/100g。

关键词: 超临界CO2, 沙棘籽油, α-VE, 胡萝卜素

Abstract:

In the present study, the supercritical carbon dioxide extraction of seabuckthron seed oil was optimized using an orthogonal array design. Besides, thermosensitive substances in seabuckthron seed oil were analyzed. The optimum extraction conditions were determined as extraction at 40 ℃ at an extraction pressure of 25 MPa and a separation pressure of 8 MPa for 120 min with a CO2 flow rate of 18 kg/h. Under these conditions, the oil yield was 52%. The content of α-VE as a thermosensitive substance in seabuckthron seed oil was 2.6% as determined by HPLC and supercritical carbon dioxide extraction resulted in a 3.7% α-VE loss when compared with cold pressing. The content of carotene in seed oil obtained by supercritical carbon dioxide extraction was 100850 μg/100 g.

Key words: supercritical carbon dioxide, seabuckthorn seed oil, α-VE, carotene
