This study was conducted to investigate the effects of -, -, -Tocopherols on oxidative stability of lipid in hamburger patties during frozen storage. Hamburger patty samples were prepared with the addition of tocopherol by fat basis: control, treat 1 (control+0.02% -tocopherol), treat 2 (control+ 0.02% -tocopherol were cooked at 85 for 3 minutes and the stored at -1 or 3). The fatty acids composition of the hamburger samples were analyzed during the storage periods (1, 20, 40, 60 and 80 days). there was no difference in the fatty acids composition among control and treatment groups in early storage time; however, content of unsaturated fatty acid was decreased in control group and slightly decreased or almost not changed in treatment groups as the storage period passed. No difference in the ratio of saturated fatty acid : unsaturated fatty acid (SFA : USFA) and saturated fatty acid : monounsaturated fatty acid : unsaturated fatty acid (SFA : MUFA : PUFA) between control and treatment groups at early storage time. However, SFA : USFA and SFA : MUFA : PUFA was decreased in control and slightly decreased or not changed in all treatment groups as the storage period passed.
