摘要: 采用顶空固相微萃取法(HS-SPME)提取清炖猪肉汤的香气成分,并结合气质联用技术(GC-MS)和气相色谱-嗅闻技术(GC-O)进行分析。采用GC-MS分析鉴定得到42种挥发性风味物质,主要包括醛类、酸类、醇类、烃类和呋喃类化合物;通过GC-O分析出19种香气活性成分,根据香气强度的大小,确定己醛、(E,E)-2,4-壬二烯醛、2-十一烯醛、1-辛烯-3-醇、1-辛醇和保留指数值为912的未知化合物为清炖猪肉汤中的关键香味化合物。

Abstract: Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O) were used to determine the volatile compounds and aroma compounds in stewed pork broth. A total of 42 volatile compounds including aldehydes, acids, alcohols, hydrocarbons and furans were identified. Meanwhile, 19 aroma compounds were identified by GC-O. According to aroma intensity, hexanal, (E,E)-2, 4-nonadienal, 2-undecenal, 1-octen-3-ol, 1-octanol and an unknown compound of RI (retention index) 912 were identified as the critical aroma compounds in stewed pork broth.

Key words: aroma compounds, gas chromatography-mass spectrometry (GC-MS), gas chromatography-olfactometry (GC-O), stewed pork broth
