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
