| 摘 要： | 把烟草中的有机酸衍生化后 ,用GC MS分别分析了烟丝干冰膨胀前后挥发性有机酸和非挥发性有机酸的含量。烟丝经干冰膨胀后 ,甲酸、乙酸、丙酸、2 甲基丙酸、丁酸、2 甲基 丁酸的含量有不同程度的升高 ,其中甲酸、乙酸的含量膨胀后明显增高 ;而戊酸、糠酸、庚酸、草酸、丙二酸、4 氧代戊酸、苹果酸、柠檬酸、肉豆蔻酸、棕榈酸、亚油酸、亚麻酸、十八碳酸的含量则有不同程度的下降。挥发性有机酸含量升高的幅度随挥发性的降低而降低 ,从戊酸开始有机酸的含量开始下降。

| Abstract: | Volatile organic acids and nonvolatile organic acids from the dry ice expanded tobacco were determined by derivation of organic acids and GC MS analysis. Contents of formic acid, acetic acid, propionic acid, 2 methyl propionic acid, butyric acid and 2 methyl butyric acid were increased, while that of valeric acid, furoic acid, heptanoic acid, oxalic acid, malonic acid, 4 oxo valeric acid, malic acid, citric acid, myristic acid, palmitic acid, linoleic acid, linolenic acid and octadecoic acid were decreased after the dry ice expansion treatment. |
