摘要
采用液液萃取法萃取老白干香型白酒中的香气成分,通过气相色谱-闻香法(GC-O)和气质联用(GC-MS)技术对老白干香型白酒中的香气成分进行了分析鉴定,共检测到了107种香气成分,鉴定出了其中的90种,其中对老白干香型白酒整体香气贡献大的香气成分有4-乙基愈创木酚、乙酸-2-苯乙酯、丁酸、3-甲基丁醇(异戊醇)、β-苯乙醇、2-乙酰基-5-甲基呋喃、苯丙酸乙酯、γ-壬内酯、3-甲基丁酸(异戊酸)、香兰素、乙酸乙酯、1,1-二乙氧基-3-甲基丁烷和(2,2-二乙氧基乙基)苯等物质,这些香气成分是老白干香型白酒的重要香气成分。
The aroma components in Laibaigan-flavor liquor were extracted by liquid-liquid extraction. And these compounds were iso lated and identified by gas chromatography-olfactometry （GC-O） and gas chromatography-mass spectrometry （GC-MS）. Total of 107 aro ma compounds were detected from Laobaigan-flavor liquor and 90 out of them were identified. Among them, 4-ethylguaiacol, 2-phenylethyl acetate, butanoic acid, 3-methyl butanol （Isoamyl alcohol）, β-phenylethanol, 2-acetyl-5-methylfuran, ethyl benzene propanoate, γ-nonalactone, 3-methylbutanoic acid, vanillin, ethyl acetate, 1,1-diethoxy-3-methylbutane and （2,2-diethoxyethyl）ben zene made great contributions. And they were very important aroma compounds for the fragrance of Laobaigan-flavor liquor.
