OAV和GC-MS-O法鉴定内蒙古风干牛肉风味活性物质

Identification of flavor- active compounds in Inner Mongolia dried beef by OAV calculation and GC-MS-O

  • 摘要: 采用同时蒸馏萃取法对内蒙古风干牛肉中挥发性化合物进行提取,并利用香气活性值(odor activity value,OAV)和气相-质谱-嗅闻(GC-MS-O)联用的方法对其中的风味活性物质进行鉴定。结果表明共发现59种挥发性化合物,OAV法和GC-MS-O法分别确定了25种和21种风味活性物质。内蒙古风干牛肉中含有丰富的风味物质,其中重要的风味活性物质主要包括α-蒎烯、萜品烯、β-甜没药烯、反-2-辛烯醛、月桂醛、苯乙醛、肉豆蔻醛、壬醛、癸醛、糠硫醇、甲基庚烯酮、茴香脑、草蒿脑、3-乙基-2,5-二甲基吡嗪、2-乙基-3,5-二甲基吡嗪、2,5-二甲基吡嗪、2,3,5-三甲基吡嗪、2,3,5,6-四甲基吡嗪。 

     

    Abstract: The volatile flavor components in Inner Mongolia dried beef were extracted by simultaneous distillation extraction( SDE) and analyzed by odor activity value( OAV) and gas chromatography- mass spectrometry-olfactometry( GC- MS- O). The results indicated that a total of 59 volatile compounds were identified in Inner Mongolia dried beef,and 25 and 21 flavor- active compounds were identified by OAV calculation and GC- MS-O. Inner Mongolia dried beef contains rich flavor substances. The important flavor- active compounds in Inner Mongolia dried beef were α- pinene,γ- terpinene,β- bisabolene,( E)- 2- octenal,dodecanal,phenylacetaldehyde,tetradecanal,nonanal,decanal,2- furfurylthiol,6- methyl- 5- hepten- 2- one,anethole,estragole,3- ethyl-2,5- dimethyl- pyrazine,2- ethyl-3,5- dimethyl- pyrazine,2,5- dimethyl- pyrazine,trimethyl- pyrazine,tetramethyl- pyrazine.
