| 摘 要： | 目的:对海南香茅油超临界CO2流体萃取工艺条件进行优化。方法:采用正交试验法,以萃取压力、萃取温度和萃取时间为考察因素,以香茅油的萃取得率为指标筛选香茅油的提取工艺。结果:优选出的香茅油最佳提取工艺条件为:萃取压力为15MPa,萃取温度为45℃,萃取时间为90min。结论:香茅油的超临界CO2萃取法较水蒸气蒸馏法具有工艺条件稳定、提取时间短、产率高等优点,为香茅油生产技术的改良提供了一定的理论依据。

| Abstract: | Objective： To optimize the supercritical carbon dioxide extraction technology of citronella oil. Methods： Ortogonality measure was applied in this study, and parameters affected the citronella oil extraction yield such as pressure; temperature, time and the percentage of extraction yield of the oil were observed to evaluate the extraction technology. Results： The optimum conditions for the citronella oil extraction included extraction pressure, 15 MPa, extraction temperature, 45 ℃ and the extraction time, 90 min. Conclusion： The above mentioned extraction technology and optimum conditions provided theory basis for the improvement of citronella oil extraction technology. |
