超临界CO2萃取技术具有安全卫生、低温操作等特点,已成功用于中草药有效成分、天然食品添加剂等的提取分离。为提高萃取分离效率,将超临界流体萃取与其它分离技术联用是重要研究方向。采用溶剂热浸提-超临界CO2萃取结晶组合工艺,可同步实现萃取与结晶分离,提高分离过程与技术的集成度,促进超临界CO2萃取技术在工业生产中的应用。
Supercritical CO2 extraction technology is safe, hygienic and low-temperature operation. It has been successfully used in the extraction and separation of the active ingredients of Chinese herbal medicine and natural food additives. In order to improve the efficiency of extraction and separation, the combination of supercritical fluid extraction with other separation techniques is an important research direction. Solvent heat extraction - supercritical CO2 extraction and crystallization combination process can be simultaneously achieved separation of extraction and crystallization, separation process and technology to improve the integration and promote the application of supercritical CO2 extraction technology in industrial production.
