| 摘 要： | 以5种山苍子精油、2种柠檬草精油为研究对象,采用ATR-FTIR结合判别分析法建立了几类天然柠檬风味精油的识别模型。模型清晰地将样品分成了3大类:低浓度柠檬醛精油、高浓度柠檬醛精油、烯烃类(柠檬烯及长叶烯)精油。利用模型可以简便、快速地鉴别不同类型的天然柠檬风味精油,为天然柠檬风味精油的快速鉴别提供了一种新的方法。

| Abstract: | Taking seven kinds of different quality of natural lemon flavor oil (five kinds of cubeba essential oil,two kinds of lemongrass essential oil) as the object,the recognition natural lemon flavor oil model was established using ATR-FTIR combined with discriminant analysis.The samples were clearly divided into three categories by model:low concentrations of citral oil,high concentrations of citral oil,limonene and longifolene oil.The model can be easily and quickly identify different quality natural lemon flavor oils.It provides a new method for the identification of natural lemon flavor oil. |
