There was a significant interaction between dietary fat supplementation and frozen storage
duration in the content of lipid oxidation (Table 2). Regarding the oxidative behaviour in
unfrozen pork, chops from pigs fed control and animal fat diets had greater (P≤0.01) TBARS
values than chops from pigs fed CaSPO1 diet. However, no significant differences (P>0.05)
were observed for lipid oxidation values between diets in 2-years frozen pork. There was not an
important increase in TBARS values during frozen storage. Those results agreed with Hansen et
al. [10], who found that TBARS values were not significant higher for frozen chops compared
to fresh samples.
