The volatile compounds of cooked meats from differently fed Belgian Blue, Limousin and Aberdeen Angus bulls were isolated in a model mouth apparatus. Their odour activity was determined by gas chromatography-olfactometry based on a detection frequency method. A total of thirty compounds possessed an odour activity in cooked beef meat. Significant influences of breed and diet on the development of...
The aroma profile of cooked beef meat has been investigated by solid-phase microextraction (SPME) combined with gas chromatography-mass spectrometry (GC-MS). Out of more than 200 volatile compounds, 36 key odour-active compounds were selected for analysis. Several extraction times, desorption times, temperature conditions and fibre types were tested to achieve a fast and reproducible extraction, and...
The volatile flavour compounds of two commercial Irish beef meats (labelled as conventional and organic) were evaluated by gas chromatography-olfactometry and were identified by gas chromatography-mass spectrometry. The volatile compounds were isolated in a model mouth system. Gas chromatography-olfactometry was performed by a group of eight assessors using the detection frequency methodology. The...
