The level of lipid oxidation of minced chicken breast and thigh patties processed by high pressure (800 MPa, 10 min, 5 C) and stored at 5 C was found to depend on location and packaging. The lipid oxidation in chicken patties occurred mainly in the surface part and antioxidant active packaging was able to delay the oxidation induced by high pressure processing and, thus extended the shelf-life. Radicals were formed during the high pressure treatment and could be trapped by the spin trapping
