Approach to evaluate the sensory quality deterioration of chicken seasoning using characteristic oxidation indicators.

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.
