中文摘要: 该研究以正丙醇、异丁醇、异戊醇、活性戊醇、β-苯乙醇5 种一元醇为测定指标，利用毛细管气相色谱法分析9 种酒曲酿造米香型白酒发酵液中的高级醇。结果表明，米香型白酒中异戊醇和异丁醇含量最高，分别占高级醇总量的32%～40%和27%～41%；其次是正丙醇，占比为7%～19%；苯乙醇和活性戊醇含量较低。9 种酒曲酿造的米香型白酒发酵液中，金黄田酒曲（JM）组中高级醇总量最高（701.62 mg/L），含量较低的为鹰金钱酒曲（YM）组和长乐烧米粉曲（CM）组，分别为410.95 mg/L 和346.83 mg/L。
Abstract:Five monoalcohols，including n-propanol，isobutanol，isoamyl alcohol，2-methyl butanol，and βphenylethanol were used as indicators for determining the content of higher alcohols in the fermentation mashes of rice-flavor Baijiu brewed with nine different Jiuqu（fermentation starters）by capillary gas chromatography. The results showed that isoamyl alcohol and isobutanol had the highest content in rice-flavor Baijiu，accounting for 32%-40% and 27%-41% of the total higher alcohols，respectively，followed by n-propanol（7%-19%）. β-Phenylethanol and 2-methyl butanol were the least. Among the fermentation mashes of riceflavor Baijiu brewed with nine different Jiuqu，JM had the highest content of higher alcohols（701.62 mg/L），while YM and CM had lower content（410.95 mg/L and 346.83 mg/L，respectively）.
