Lipid Oxidation in Chicken Muscles and Skin After Roasting and Refrigerated Storage of Main Broiler Parts

The muscles and attached skin of fresh chicken broiler parts, which were roasted in a convection oven and subsequently kept at 4°C for 4 days were analyzed for lipid oxidation products (LOP). Roasting and refrigerated storage significantly increased the amount of malonaldehyde which occurred faster in the skin than in the muscles. Also, after roasting, lipid oxidation fluorescence products increased in the aqueous phase and, after refrigerated storage, in the organic phase of Folch extracted muscles and skin. The lowest concentration of LOP was found in roasted, separated parts of broilers, especially in the drumsticks and wings as opposed to roasted carcass halves or quarters. The absolute amount of LOP in muscles and skin after roasting was a result of initial concentrations of LOP in raw samples and the type of roasted broiler parts.
