    摘要:

    采用顶空固相微萃取与GC-MS联用方法对煎鸡蛋中挥发性成分进行提取与分析,考察萃取头、萃取温度和吸附时间对分析结果的影响,得到优化的顶空固相微萃取条件为:黑色萃取头(75μm Carboxen/PDMS),吸附温度75℃,吸附时间70min。在优化的条件下分析,共鉴定出50种挥发性风味成分,其中醛类16种(40.588%)、含氮化合物14种(23.639%)、醇类8种(7.156%)、烃类3种(4.800%)、酚类及杂环化合物3种(1.755%)、酮类3种(0.868%)及含硫化合物3种(0.563%)。鉴定出含量较高(相对峰面积大于2.5%)的物质有:2,5-二甲基吡嗪、3-甲基丁醛、2-甲基吡嗪、壬醛、苯甲醛、反,反-2,4-癸二烯醛、辛醛、2-甲基丁醛、反-2-癸烯醛、R(-)3,7-二甲基-1,6-辛二烯、1-辛烯-3-醇。

    Abstract:

    Volatile flavor components in fried eggs were extracted by head space solid phase microextraction (HS-SPME) and analyzed by gas chromatography-mass spectrometry(GC-MS). A 75μm Carboxen/PDMS, adsorption time of 70min, a temperature of 75℃ were selected as the optimum conditions. This optimized method was applied to analyze a real sample. A total of 50 volatile compounds were identified in fried eggs, including 16 aldehydes (40.588%), 14 nitrogen-containing compounds (23.639%), 8 alcohols (7.156%), 3 hydrocarbons (4.800%), 3 phenols and heterocyclic compounds (1.755%), 3 ketones (0.868%), 3 sulfocompounds(0.563%). The relative contents of main volatiles (above 2.5%) were as follows: 2,5-dimethyl-pyrazine, 3-methyl-butanal, methyl-pyrazine, nonanal, benzaldehyde, (E,E)-2,4-decadienal, octanal, 2-methyl-butanal, (E)-2-decenal, 3,7-dimethyl-1,6- octadiene, 1-octen-3-ol, et al.
