摘要: 采用超临界CO2萃取八角茴香精油,利用单因素试验及响应面法对工艺进行优化,优化后的工艺条件为萃取温度37 ℃,萃取压力17 MPa,CO2流量25 L/h,萃取时间95 min,在此条件下,八角茴香精油平均收率为9.1%。通过试验验证,响应曲面分析法适用于超临界CO2萃取八角茴香精油的工艺研究,有效减少了试验次数,降低了试验成本。

Abstract: Star anise essential oil by supercritical CO2 was extracted, and the process was optimized by single factor experiment and response surface methodology. The optimized process conditions were the extraction temperature of 37 ℃, the extraction pressure of 17 MPa, the CO2 flow of 25 L/h, and the extraction time of 95 min. Under these conditions, the average yield of star anise essential oil was 9.1%. Through the verification test, the response surface methodology is suitable for the process study of supercritical CO2 extraction of star anise essential oil, which effectively reduces the number and cost of tests.

Key words: star anise essential oil, supercritical CO2, extraction, response surface methodology
