For most cooked meat products, the antioxidant enzymes were
active only in raw meat, and most or even all of their activities lost
when meat was cooked (Mei, Crum, & Decker, 1994). However, in
our present study, though the activities of all antioxidant enzymes
decreased during processing, all of them still retained part of the
activity until the end of process. The GSH-Px activity for each treatment
decreased by 38.8% (LT&LS) (p < 0.05), 50.7% (LT&HS)
(p < 0.01), 31.3% (HT&LS) (p < 0.05) and 49.3% (HT&HS) (p < 0.01)
in relation to raw material, respectively (Fig. 1
