In this research antioxidants effectiveness in the stability of minced anchovy Engraulis ringens during frozen storage were evaluated. The antioxidants used were: 0,1% sodium erisorbate + 0,025% EDTA + 0.5% TPP ; 0.02% TBHQ + 0.01% EDTA; and 0.01% α-tocopherol + 0.05% ascorbic acid + 0,01% soy lecithin. Samples were vacuum-packed, frozen and stored at -25 C . Chemical and sensory changes were followed for 7 months; the blank test was found acceptable by the panel until the third moth, the treatments evaluated by sensorial panel showed no significant differences until 5 months of storage, however at 7 months, significant differences among treatments were observed. The best result, by sensorial evaluation was obtained with the mixture of TBHQ + EDTA, the results obtained in this research suggest that antioxidants used protect the minced during frozen storage. Antioxidants and storage time interaction had influence on peroxide value (r2 = 0,964), TBA (r2 = 0,964) and free fatty acids (r2 = 0,996). An increase in free fatty acids to around 6% was observed, indicating that the enzyme activity was not affected by freezing or by treatment with antioxidants. Key Word: Anchovy, Engraulis ringens, antioxidants, peroxide value, free fatty acids.
