Abstract:

The effect of different reaction temperatures on sensory quality and volatile flavor compounds of Maillard
reaction products (MRPs) derived from bovine bone hydrolysate was determined by gas chromatography-mass spectrometry
(GC-MS) and electronic nose. The results showed that MRPs generated at different temperatures exhibited high variability
in sensory quality and volatile flavor. The meat flavor produced at 105 ℃ had obvious advantages in the terms of flavor and
taste. In the meantime, it contained much more volatile flavor substances, which could reach 93.62% as detected by GCMS.
In particular, pyrazine compounds as characteristic flavor components accounted for 8.19%. The contents of aldehydes
and ketones were higher as well. The meat flavor manufactured under this condition was dark brown, and had full bodied
fragrance and a lasting aftertaste. At the same time, electronic nose analysis revealed that products obtained at different
reaction temperatures had significant differences in volatile flavor composition.

Key words: meat flavor, volatile flavor composition, temperature, Maillard reaction
