摘　　要：白酒中的微量成分及其重要,特别是(酯、醇、醛类)含量的高低是评价白酒质量好坏的重要指标之一。本文在参照国标检验方法下,对其检测方法进行改善、优化和创新,采用DB-WAX UI毛细管柱气相色谱法同时测定芝麻香型白酒中酯、醇、醛三类风味成分,以叔戊醇、乙酸正戊酯为内标法进行定量,得到了分离效果较好的色谱峰,且检测时间短,操作简单,可同时检测芝麻香型白酒中11种香味成分的含量,对白酒的质量进行很好的监测,更好的指导企业生产。Trace components in Baijiu are extremely important,especially the content of esters,alcohols and aldehydes,are one of the important indicators for evaluating the quality of Baijiu.This article improves,optimizes,and innovates the detection method based on the national standard inspection method.And esters,alcohols and aldehydes in sesame flavor Baijiu were simultaneously determined by DB-WAX UI capillary column GC.Quantitative analysis was performed using tert amyl alcohol and n-amyl acetate as internal standards method.With this method,a chromatographic peak with good separation effect is obtained,and the detection time is short and the operation was simple.This method can effectively improve the work efficiency in the daily detection of Baijiu,quickly detect the content of 11 target substances at the same time,monitor their quality,and better guide enterprise production.
