超临界CO_2萃取植物天然香料的研究进展

Research Progress in Supercritical CO_2 Extraction of Aromatic Plants

超临界CO2萃取技术是一种新兴的分离技术,它具有萃取效率高、分离工艺简单、不需要溶剂回收设备、工作条件温和、无毒、无残留等特点,在天然香料领域的应用越来越广泛。从植物根茎叶芳香成分、水果芳香成分和鲜花芳香成分三个方面对超临界CO2萃取技术在天然植物香料提取方面的最新应用研究进行了总结,并对超临界流体萃取在天然香料领域的发展前景作了展望。

As a new separation technology, supercritical C02 extraction was applied widely in natural aroma separation.We summary the latest research activities and progresses in supereritical C02 extraction of aromatic plants from three aspects of which are aromatic componentsare of root, stem and leaves, aromatic componentsare of fruit, and aromatic componentsare of flowers. And the developing prospect of supercritical fluid extraction in natural aroma separation is put forward.
