摘要:

采用同时蒸馏提取制样,通过气相色谱-嗅闻-质谱联用对熟牦牛肉的挥发性风味物质进行分析,共检测出 72 种化合物,其中酯类4 种、羰基化合物31 种、醇类6 种、烃类13 种、醚类1 种,酚类2 种、杂环化合物7 种,含 硫化合物6 种、未知化合物2 种。通过嗅闻仪检测表明:异丁酸、丁酸、1-戊烯-3-酮、2,3-戊二酮4 种化合物具有强 烈的刺激性气味,对牦牛肉腥膻味的形成影响较大。

关键词: 牦牛肉, 膻味, 气相色谱-质谱-嗅闻联用

Abstract:

The flavor compounds of cooked yak meat were investigated by gas chromatography-olfactometry-mass
spectrometry (GC-O-MS) and simultaneous distillation extraction (SDE). A total of 72 flavor compounds were identified
including 4 esters, 31 carbonyl compounds, 6 alcohols, 13 hydrocarbon compounds, 1 ether, 2 phenolic compounds, 7
heterocyclic compounds, 6 sulfur-containing compounds and 2 unknown compounds. Meanwhile, 2-butanoic acid, butanoic
acid, 1-penten-3-one and 2,3-pentanedione were identified by olfactometry to have a strong pungent odor, which made a
great contribution to the formation of the disgusting odor of yak meat.

Key words: yak meat, disgusting odor, gas chromatography-olfactometry-mass spectrometry (GC-O-MS)
