Generally, temperature is an important factor affecting the
quality development of dry-salted or dry-cured meat products during
processing, and increasing process temperature could promote
lipid oxidation in meat. However, the effect of temperature on
endogenous enzyme activities in meat products is usually complicated,
because temperature could significantly influence the chemical
compositions of meat, such as the salt content and water
activity (aw), etc. During dry-salted or dry-cured meat products
processing, increasing temperature could accelerate the moisture
loss of samples, and thus causing the salt content increase. Therefore,
under the conditions of high process temperature, even the
initial amount of added salt was relatively lower, it still showed
a marked inhibitory effect on antioxidant enzyme activities and a
promoting effect on lipid oxidation. This just was the cause for that
the correlations between lipid oxidative indices (PV and TBARS)
and antioxidant enzyme activities in high-temperature treatment
groups were weaker than those in low-temperature treatment
groups correspondingly
