白酒承载了中国特色文化,其品质与酒中的风味物质密切相关.在白酒酿造过程中,杂醇油的生成是必然的.适量的杂醇油会使酒体更为协调;过多的杂醇油会引起酒后“上头”,给饮用舒适感带来一定影响
杂醇油是酒的芳香成分之一，是评价酒卫生质量的指标之一。酒中适量杂醇油能增加酒的香味，给人以美味的感觉。但过量则对机体产生毒害作用。其中毒和麻醉作用较强，能使神经系统充血，引起头晕、头痛。其毒性随醇类分子量的增大而加剧。杂醇油是一种混合物的总称，其成分复杂，主要为异戊醇、异丁醇、戊醇、丁醇、己醇等高级醇类，
浩瀚色谱采用GDX104柱直接进样、氢火焰离子化检测器,建立了气相色谱同时测定白酒中的甲醇和杂醇油的分析方法.甲醇和杂醇油的检出限均为2.0×10-4 g/(100 mL),回收率分别为96.4%～99.1%、91.2%～98.3%,相对标准偏差不大于4.3%.该方法适用于白酒中甲醇和杂醇油的同时分析测定.

Baijiu carries the culture with Chinese characteristics, and its quality is closely related to the flavor substances in the liquor. In the process of Baijiu brewing, fusel oil is inevitable. Proper fusel oil will make the liquor body more harmonious; Excessive fusel oil can cause hangovers and have a certain impact on drinking comfort
Fusel oil is one of the aromatic components of wine and one of the indicators for evaluating the hygiene quality of wine. Moderate amount of fusel oil in wine can enhance its aroma and give people a delicious feeling. But excessive amounts can have toxic effects on the body. Its toxic and anesthetic effects are strong, and it can cause congestion of the nervous system, leading to dizziness and headache. Its toxicity intensifies with the increase of alcohol molecular weight. Fusel oil is a general term for a mixture of complex components, mainly consisting of higher alcohols such as isoamyl alcohol, isobutanol, pentanol, butanol, hexanol, etc,
A method for the simultaneous determination of methanol and fusel oil in Baijiu by gas chromatography was established using GDX104 column direct injection and hydrogen flame ionization detector. The detection limits of methanol and fusel oil were 2.0 × 10-4 g/(100 mL), and the recovery rates were 96.4% ～ 99.1% and 91.2% ～ 98.3%, respectively. The relative standard deviation was not more than 4.3%. This method is suitable for the simultaneous determination of methanol and fusel oil in Baijiu
