Abstract:
Glutathione (GSH) is an important precursor of meat flavor. This study aimed to evaluate the effect of GSH-curing on the flavor of cooked chicken. GSH-cured chicken with different concentrations and uncured chicken (blank) were roasted separately and comprehensively analyzed in terms of flavors, odor-active compounds, free amino acids, and fatty acids profile. Volatile flavor compounds were analyzed using solid-phase micro-extraction (SPME) along with GC-MS, GC-O/AEDA, and odor activity value (OAV) calculations. The results showed that the contents of most flavors derived from the Maillard reaction increased due to GSH-curing treatment, such as 2-methylthiophene, 3-methylthiophene, 2-methylthiazole, and 5-methylthiazole, while the lipid degradation flavors reduced, like hexanal, heptanal, and (E,E)-2,4-decadienal. In particular, during sensory analysis, the cured sample with 1.6 mmol GSH had the greatest roasted meaty odor. In addition, GSH curing results in the increased formation of key odor-active substances (OAV ≥ 1), such as 2-acetylthiazole.
