摘要: Presence of tocopherol is effective for fish preservation during frozen storage, inhibiting lipid degradation by oxidation. This work evaluated the antioxidant effects α-tocopherol in diet and postmortem addition on final quality hamburgers produced from tilapia fillets kept zero, 30, 60, 90 days. Chemical composition varied within values found fish. The increase levels reduced thiobarbituric acid reactive substances (TBARS) samples at all time intervals. Tocopherol supplementation diets protected oxidation more effectively than addition.
