摘要
超临界流体萃取法是使用超临界流体作为萃取溶剂的方法,分离析出溶质时使用压力变化、温度变化、吸附法。采用超临界二氧化碳萃取具有低温处理,能有效地萃取易挥发性物质,无氧化变质．对人体无害,稳定安全等优点。超临界流体萃取技术在食品工业中主要用于香精、香料、色素的萃取,油脂的萃取、脱色、脱臭,食品原料的脱脂,脱咖啡因以及油脂混合物的分离、精制等。
Super critical fluid extraction is using super critical fluid as extreacting solvent. The super critical carbon diox-ied extraction has the advantages of low temperature treatment, effectively extracting volatility substance, no oxidating deterioration . harmless to the health , stability and safety. Super critical fluid extraction in food industry is mainly used in extractions of essence , perfume , pigment oil , decolor deodorization , and also used in de - fat of food materials , degreassing caffeine, separating oil mixture and purification.
