Patties made of minced chicken breast and thigh packed in standard vacuum-packaging (C) or in antioxidant
active packaging (AP) were subjected to high pressure treatment (800 MPa, 10 min, 5 C) and subsequently
stored for 25 days at 5 C. Lipid oxidation was studied at the surface (S) and the inner (I) parts
of the meat patties. The lipid oxidation was higher in the surface part and the active packaging was able
to delay it up to 25 days. The lipid oxidation was limited in the inner part of the meat patties and
restrained at the surface of the active packaging. It was found that the effect on lipid oxidation by high
pressure may not be explained solely by cell membrane damage, as radicals were formed in the meat during
the pressure treatment.
