Abstract:
Sensory quality deterioration of chicken seasoning was investigated using physicochemical properties, gas chromatography-mass spectrometry (GC-MS) and descriptive sensory analysis to approach an evaluation of the chicken seasoning deterioration. It was found that both peroxide value (POV) and total oxidation value (TOTOX) increased with the chicken seasoning deterioration, suggesting a dominant of the lipid oxidation in the sensory quality deterioration of chicken seasoning. Moreover, a continuously decreasing linoleic acid and contradictory increasing in volatile aldehydes (specifically for hexanal) indicated as characteristic oxidation indicators to evaluate the sensory quality deterioration. PLSR results further elucidated that the evolution of aldehydes was highly correlated with sensory quality deterioration. These results suggest the POV, TOTOX and hexanal as valuable indicators and provide a novel approach to quality and rapidly evaluate the sensory quality deterioration of chicken seasoning.
