| 摘 要： | 乙酸乙酯、杂醇油作为白酒中重要的呈香呈味物质,其含量的高低直接影响着白酒的风格.开展本项实验的目的正是在于开发快速、方便、高效、准确地测定白酒中乙酸乙酯、杂醇油含量的方法.该方法是以正丁醇为内标,以氢火焰离子化为检测器,以高效毛细管柱为分离柱,并辅助以程序升温的气相色谱法.以气相色谱法对几种地方白酒中的乙酸乙酯、杂醇油的定性、定量分析为实例,介绍了实验操作过程,确定了实验条件,并对实验结果进行了分析、讨论和总结.该实验克服了常规法测定白酒中乙酸乙酯、杂醇油含量时操作繁琐、操作时间长的缺点,实现了较好的分离效果和实验精密度.该方法检出数量级可达到10-12,一般样品只要几分钟即可完成.

| Abstract: | The ethyl acetate and the fusel oil is important taste material,the content of which has a direct influence on the taste of liquor.Using the method of capillary column gas chromatography to determine the ethyl acetate and the fusel oil content of wines is an easy and qulck way.Appling column temperature program,taking the Flame Ionization Detector as the detector and the n-amyl alcohol as the internal market,it can separate and quantify the ethyl acetate and the fusel oil content.The experimental result has... |
