摘要
目的:研究与优化微波技术提取沙棘籽油的工艺。方法:以提油率为指标,以微波功率、微波时间、液料比为考察因素,利用正交设计法筛选优化微波提取沙棘籽油的提取工艺。结果:微波提取沙棘籽油的最佳工艺条件是:微波功率539W,微波时间7 min,液料比8。此工艺条件下沙棘籽油的提取率为89.36%。结论:相比于传统提取方法,微波提取技术具有提取效果好,提取效率高的特点,可将微波提取技术应用到沙棘籽油的提取工艺中以提高产率、降低提取时间。
Objective： To study and optimize the extraction process of seed oil of Hippophae rhamnoides L. by microwave extraction technology. Methods： The orthogonal design method was used to optimize the extraction process seed oil of Hippophae rhamnoides L. by microwave extraction technology with the oil yield as the index and microwave power,microwave time and liquid to solid ratio were taken as study factors. Results： The optimum extraction process was as follows： microwave power at 539 W,microwave time at 7 min and liquid to solid ratio at 8. The extraction rate of oil was 89. 36% under this extraction conditions. Conclusion： Microwave extraction technology may have good extraction yield and high extraction efficiency compared with traditional extraction methods. It is suitable to apply microwave technology into the extraction process of seed oil of Hippophae rhamnoides L.with the purpose of increasing the yield and reducing the extraction time.
