| 摘 要： | 用超临界CO2萃取技术结合分子蒸馏纯化制取橙花精油。通过正交实验确定了超临界CO2萃取最佳工艺条件,即萃取时间240min,萃取温度40℃、萃取压力20MPa、萃取流速20L.h-1。用气相色谱/质谱(GC/MS)联用仪对橙花精油成分进行了分析,共检测出54种化合物。用超临界CO2萃取结合分子蒸馏制取橙花精油的方法具有工艺操作温度低、基本上不破坏热敏性物质、精油香气更接近天然、无溶剂残留等优点。

| Abstract: | Neroli oil was prepared by supercritical CO2 extraction combined with molecular distillation.Best process conditions of supercritical CO2 extraction were determined by orthogonal experiments:extraction time 240min,extraction pressure 20MPa,extraction temperature 40℃,CO2-flow 20L/h.The compositions of neroli oil were analyzed by gas chromatography/mass spectrometry(GC/MS) apparatus,and the 54 kinds of components were detected.The supercritical CO2 extraction method combined with molecular distillation basically did not destroy the heat-sensitive materials at low operation temperature,the aroma of essential oil was close to the original aroma,the prepared neroli oil did not contain solvent residual. |
