Effect of frozen storage(0, 15, 30, 40 days, -18$^{circ}C$), cooking methods(frying, microwaving) and reheating on lipid oxidation in chicken meats were evaluated by measuring thiobarbituric acid value (TBA value) and by measuring fluorescence value. TBA values were increased by storage days and were higher in leg meats than breast meats. According to cooking method, TBA values were higher in frying chicken meats. The fluorescence values were also increased by storage days and were higher in breast meats than leg meats.
