Effect of frozen storage duration on temporal dominance of sensations (TDS), chemical investigations and moisture distribution of roasted chicken wings.

In order to guide manufacturers or consumers to choose frozen chicken wings (CWS) reasonably for roasting, the changes of sensory quality and physicochemical properties of CWS with different freezing storage time (0-12 months) after roasting were studied. The results showed that juiciness, fat flavor, meat flavor, and saltiness were the most important dominant attributes of roasted CWS, and their dominance rate gradually decreased from the ninth month. Increased (P < 0.05) TBARS value and water loss result in poor juiciness. According to the results of GC-IMS, the decrease of the dominant rate of meaty may be related to the decrease of the contents of 2-ethyl-5-methylpyrazine, benzene and thiazole. In addition, the accumulation of 1-octen-3-ol, n-hexanol, and hexanal caused by long-term freezing (> 9 months) give chicken wings a fishy and metallic taste. Therefore, CWS that have been frozen for more than 9 months are not ideal ingredients for roasting.
