Abstract: The volatile compounds in spiced donkey meat were extracted by solvent-assisted flavor evaporation (SAFE) and identified by odor activity value (OAV) calculation and gas chromatography-olfactometry-mass spectrometry (GC-O-MS). A total of 48 volatile compounds were identified in spiced donkey meat and 13 and 21 flavor-active compounds were identified by OAV calculation and GC-O-MS, respectively. The combination of two methods suggested that the key flavor-active compounds (OAV > 200 and aroma intensity = 3) included cineole, eugenol, anethole, 1-nonanal, 2-methyl pyrazine, 2,6-dimethyl pyrazine, 2-acetyl pyrrole, and maltol.

Key words: spiced donkey meat, solvent-assisted flavor evaporation, flavor-active compounds, gas chromatography-olfactometry-mass spectrometry, odor activity value
