摘要
采用顶空固相微萃取法(HS-SPME)提取烤牛肉的挥发性成分,并结合气-质联用技术(GC-MS)分析其挥发性成分物质。结果表明:在烤牛肉中鉴定出42种挥发性成分,主要包括羧酸类化合物、醛类化合物、酚类化合物、醇类和杂环类(吡嗪环、噻唑环)化合物;并在GC-MS基础上,利用感官分析模拟出香气饱满、逼真、协调的烤牛肉香精;最后,通过电子鼻确定了模拟的烤牛肉香精与样品烤牛肉的香气相似度达92.4%。
The applicability of headspace solid-phase microextraction（HS-SPME） combined with gas chromatography and mass spectrometry （GC-MS） for determination of volatile components in roasted beef was investigated. The results showed that the 42 volatile components were indentified, including carboxylic acid compounds, aldehyde compounds, phenolic compounds, heterocyclic compounds （pyrazine ring, thiazole ring） and alcohols. Based on GC-MS analysis, realistic and coordinated roasted beef flavor was simulated using sensory analysis. And its aroma profile was similar with the roasted beef determined up to 92.4% by electronic nose （E-nose）.
