摘要
采用气相色谱法可对啤酒中的高级醇、酯类、羰基化合物及含硫化合物等挥发性物质进行检测,既可研究啤酒的感官品质,也可用于指导生产,优化啤酒工艺。应用气相色谱法对啤酒中挥发性物质检测的前处理方法主要有顶空进样、蒸馏、有机溶剂萃取3种。针对啤酒酒中不同的挥发性物质可选择PEG柱和氢火焰离子化检测器(FID)法进行检测;还可用内标法和外标法对啤酒中的不挥发组分进行定量检测分析。
Volatile substances in beer such as higher alcohol, esters, carbonyl compound and sulfur compound etc. were measured by gas chromatography, the data of which could be used for beer quality analysis, beer production guidance, and beer technology optimization. The pretreatment of volatile substance by gas chromatography mainly included headspace sample injection, distillation, and organic solvent extraction. In view of different volatile substance in beer, PEG column and FID （hydrogen flame ionization detector） were selected in the measurement. Besides, quantitation analysis of involatile compositions in beer could be done by internal standard method or by external standard method. （Tran. by YUE Yang）
