Analyses were conducted at T0 and after 3, 6, 12, 15 and 18
days of storage. According to sensory tests and colour analyses, the fillets in the MAP and MAP-AOX
groups maintained the best appearance. In the CO group, we observed a significant decrease of
omega-3 polyunsaturated fatty acids (FAs) (P < 0.05), which indicates the oxidation of these FAs. FAs in
the MAP and MAP-AOX groups were protected against oxidation. Further, lower peroxide value (PV) and
malondialdehyde (MDA) content were observed in the MAP and MAP-AOX groups compared to the CO
group. The sensory properties of the fillets were correlated with changes in FA content, PV and MDA
content.
