Abstract

This paper deals with the heat penetration characteristics，quality change and quality kinetics of roasted broiler chicken wings with different moisture contents (w =30% ～40%) sterilized at different lethality values (F =0 ～5min)． The results indicate that (1) the heating and cooling rate indexes (f h and f c ) as well as the heating and cooling lag factors (j h and j c ) both decrease with the decrease of moisture content; (2) samples with lower moisture content may reach a higher lethality value at the same heating and holding time; (3) F value has no obvi-ous effect on the water activity a w (P ＞0． 05); (4) the curves of TBA value obey the zero-order kinetic equation and the corresponding reaction rate k increases with the decrease of moisture content; (5) sterilization with low le-thality value helps to improve the shear force，hardness and chewiness of roasted broiler chicken wings，and the corresponding decreasing curves all obey the first-order kinetic equation; and (6) the damage rates of shear force，hardness and chewiness all decrease with the decrease of moisture content．

Key words： roasted broiler chicken wing; heat sterilization; moisture content; heat penetration characteristic; quality kinetics
