All antioxidant enzyme activities decreased significantly during
dry-salted bacon processing, which reduced the oxidative stability
of bacon muscle to some extent. Antioxidant enzyme activities
were affected interactively by process temperature and salt content
in the bacons. For all dry-salted or dry-cured meat products
processing, a normal rate of lipid oxidation is necessary for the
development of cured flavour, while the extensive lipid oxidation
can cause the rancidity. So, the activities of these antioxidant enzymes
should be properly modulated during dry-salted or drycured
meat products processing. And more researches need to be
done to study the interactive effects of process factors on antioxidant
enzyme activities during dry-salted or dry-cured meat products
processing.
