洋葱精油所具有的突出的保健作用逐渐被人们所关注。介绍了水蒸气蒸馏法和有机溶剂提取法在洋葱精油提取中的劣势,通过对超临界流体萃取技术原理和工艺的阐述,比较得出超临界流体萃取技术在洋葱精油高效提取中所以具有的显著优势。综述了国内外学者在该研究方向的研究进展,并对其进行展望。
Onion essential oil has the outstanding health care has gradually been of concern. The disadvantages of water vapor distillation and organic solvent extraction in the extraction of onion essential oil were introduced. Based on the principle and technology of the supercritical fluid extraction, the results showed that the supercritical fluid extraction has significant effect on the efficient extraction of onion essential oil Advantage. The research progress of scholars both at home and abroad in this research direction is summarized and its prospect is prospected.
