摘要:

采用动态顶空制样/吹扫捕集提取发酵牛肉中的挥发性香味物质,用Tenax柱将其浓缩,浓缩物用气相色谱-嗅闻/气质联用(GC-O/GC-MS)进行分离鉴别。结果共检出19种化合物,这些化合物的气味特征包括果香、巧克力香、松脂香、咸鱼味、洋葱味、玫瑰甜香、薄荷、黄油味、花香等,其中醛、醇、酯、酮和芳香族碳氢化合物、含硫化合物、吡嗪等是主要成分。

关键词: 发酵牛肉, 香味活性化合物, 气相色谱-嗅闻/气质联用(GC-O/GC-MS), 动态顶空制样

Abstract:

Volatile flavor compounds in fermented beef were sampled using dynamic headspace sampling and purge-and-trap techniques, concentrated using a Tenax adsorption column and analyzed by GC-O/GC-MS. Totally 19 compounds were identified including aldehydes, ethanols, estes, ketones, aromatics, sulfur compound and pyrazine, etc, which gave the flavors of fruit, chocolate, rosin, salted fish, onion, rose, mint, butter and flower, etc.

Key words: fermented beef, flavor compounds, GC-O/GC-MS, dynamic headspace sampling
