Antioxidant active packaging for chicken meat processed by high pressure treatment

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 degrees C) and subsequently stored for 25 days at 5 degrees 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.
