白酒中杂醇油分析方法的研究进展

杂醇油是工业发酵生产酒精、白酒等的副产品，是指除甲醇、乙醇以外的高级醇类，包括正丙醇、异丙醇、正丁醇、异丁醇、正戊醇、仲戊醇、己醇、庚醇等。国家标准规定分光光度法和气相色谱法为杂醇油的分析方法。毛细管柱气相色谱法是国家标准规定以外分析杂醇油的方法，该法具有渗透性好、分析速度快、进样量少、总柱效高等优点，在工业发酵产品的分析上应用较广泛。随着分析技术的发展，对白酒中杂醇油的分析方法在进一步的改进。

Research Progress in Analytical Methods of Fusel Oil in Liquor

Fusel oil as the byproduct in alcohol production and liquor production referred to all higher alcohols except ethanol and methanol including n-propanol, isopropanol, n-butylalcohol, isobutanol, sec-amyl alcohol and hexanol etc. Spectrophotometric method and gas chromatography were the authorized national standard analytical methods to fusel oil. Capillary column gas chromatography although not authorized analytic method was also considered as an effective method with its characteristics as good permeability, rapid analysis, small sample filling and high total column efficiency etc. Such method was widely applied in the analysis of fermenting products in industry. With the development of analytic techniques, the analytic methods of fusel oil in liquor could be further improved.
