利用国标（GB/T 5009.48-2003）法、气相色谱法对本厂两种不同香型（浓香型与芝麻香型）白酒中甲醇含量进行测定，结果显示浓香型白酒甲醇两种方法的检测结果基本一致，但芝麻香型白酒国标法甲醇检测结果较气相色谱法高。针对这一现象，对其产生的原因进行了分析，验证，发现芝麻香型白酒背景成分会对国标法甲醇检测产生干扰。在此基础上，对国标法测定甲醇进行了标准曲线优化、芝麻香白酒背景扣除，从而建立了一种适合芝麻香型白酒甲醇日常检测的方法。

Using GB/T 5009.48-2003 and GC method, methanol in two different flavor (Luzhou-flavor and Sesame flavor) liquor of Xuanjiu weremeasured,andtheresultrevealedthatthemethanoldatainLuzhou-flavorwerebasicallythesame,whileinSesameflavorthattested by GB method was higher than GC. This phenomenon was assayed and the reason turned out to be that the background component affected the determination of methanol. After optimization of the standard carve and deduction of background component, a method for methanol testing in Sesame flavor was established.
