Remarkably, the level of lipid oxidation in the surface of the patties packed without antioxidant (CS) was significantly higher than the rest of samples throughout the storage period. Contrary, it was also observed that the level of lipid oxidation in the inner part in the active packaging (API) tended to be lower than in the control patties. At day 25 the oxidation levels were statistically grouped into (decreasing order): CS > CI = APS > API
