摘要: 采用同时蒸馏萃取法(simultaneous distillation extraction,SDE)提取鹅肥肝的挥发性风味物质,结合气质联用技术(gas chromatography-mass spectrometry,GC-MS)和气相色谱-嗅闻技术(gas chromatography-olfactometry,GC-O)对其挥发性风味物质和主体风味物质进行分析。鉴定出41种风味成分,其中烃类8种、醇类4种、酚类2种、醛类7种、酮类5种、酸类1种、酯类7种、其他7种,3种未鉴定出。同时6种物质对鹅肥肝的风味有较大贡献,分别是己醛、2-乙基环己醇、壬醛、6,10,14-三甲基-2-十五烷酮、十四烷醛和邻苯二甲酸二正辛酯。

Abstract: The volatile compounds in foie gras was extracted by simultaneous distillation extraction (SDE) and analyzed by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O). Totally 41 volatile flavor compounds were identified including 8 hydrocarbons, 4 alcohols, 2 phenols 7 aldehydes, 5 ketones, 1 acids, 7 ester, 7 other compounds and 3 unknown compounds. Among these compounds, hexanal, 2-ethylcyclohexanol, nonanal, 2-pentadecanone, 6,10,14-trimethyl-tetradecanal, di-n-octyl phthalate made a greater contribution to the flavor of foie gras.

Key words: foie gras, simultaneous distillation extraction (SED), gas chromatography-mass spectrometry (GC-MS), gas chromatography-olfactometry (GC-O), volatile flavor constituents
