摘要
采用乙醚直接萃取和蒸馏-乙醚萃取2种方法提取,以气相色谱一质谱法对啤酒的风味物质进行定性分析,从啤酒中共分离鉴定出37种成分,其主要成分是甲酸异戊酯、甲酸异丙酯、苯乙醇、异戊醇、2-乙氧基丙醇等酯类和醇类物质,它们的含量约占总量的70%以上。
The beer sample are treated by aether extraction and distillation-aether extraction, then separated and determined by gas chromatography-mass spectrometry (GC-MS), 37 kinds of flavor volatiles have been identified, five main compounds (1-Butanol-3-methyl-formate, Formic acid-l-methylethyl ester, Phenylethyl Alcohol, 1-Butanol-2-methyl, 2-Ethoxy-l-propanol) represented more than 70 % of the total contents.
