Variance analysis results indicated that both temperature and
salt content had significant (p < 0.05) influence on the activity of
GSH-Px. However, up to now, few researches were focused on
the effect of process temperature on antioxidant enzyme activities
in cured meat products. And most of the available data were about
the cooked meat products, in which GSH-Px was usually inactivated
by high cooking temperature (Mei et al., 1994). Hoac, Daun,
Trafikowska, Zackrisson, and Åkesson (2006) found that, presence of
NADPH; Tabatabaie and Floyd (1994) reported that GSH-Px was
self inactivated by reactive oxygen species.
