摘要:

采用微波辅助萃取耦合溶剂辅助风味蒸发法提取酱牛肉挥发性成分,利用气相色谱-质谱联用仪结合保留指数定性分析酱牛肉的挥发性成分,共鉴定出65种化合物,包括11种醇,10种醛,3种酮,8种含氮、含硫或杂环化合物,9种酸,6种酯,3种醚,14种烃和1种酚。采用嗅闻频率检测法对酱牛肉挥发性成分进行GC-O分析,嗅觉检测频率≥5/11的化合物有壬醛、5-甲基糠醛、薄荷酮、茴香脑、麦芽酚、反-肉桂醛、肉桂醇。

Abstract:

Volatile components of sauced beef were extracted by microwave-assisted extraction coupled with solventassisted
flavor evaporation (MAE-SAFE) and identified by gas chromatography-mass spectrometry (GC-MS) combined
with retention indices. Totally 65 volatile compounds were identified, including 11 alcohols, 10 aldehydes, 3 ketones,
8 nitrogenous compounds, sulfur compounds and heterocyclic compounds, 9 acids, 6 esters, 3 ethers, 14 hydrocarbons
and 1 phenol. As analyzed by gas chromatography-olfactometry (GC-O), the compounds with detection frequency
larger than or equal to 5/11 were nonanal, 5-methyl furfural, piperiton, anethole, maltol, (E)-cinnamaldehyde and
cinnamyl alcohol.

Key words: sauced beef, volatile compounds, microwave-assisted extraction coupled with solvent-assisted flavor evaporation (MAE-SAFE), gas chromatography-mass spectrometry (GC-MS), gas chromatography-olfactometry (GC-O)
