Notes:
Approximately 30 million pounds of mullet are harvested annually in Florida. However, mullet has only limited economic value compared to other commercially valuable fish species which in part is due to the poor stability of the flesh during storage. The instability of mullet flesh during storage has been attributed mainly to the development of oxidative rancidity. The purpose of this study was to retard rancidity development in the stored mullet fillets by chemical and physical treatments. The mullet fillets were dipped for 1 min in the following antioxidant solution, mono-tertiarybutylbydroquinone (TBHQ), disodium ethylene-diaminetetraacetate (Na2EDTA) and ascorbic acid, singularly or in various combinations. Each antioxidant and their combinations retarded rancidity development in the stored mullet fillets. The chemcial tests (peroxide value and TBA number) indicated that ascorbic acid alone or in combination with TBHQ or Na2 EDTA was more effective than other antioxidant treatments. Vacuum packaging in combination with anti-oxidants improved rancidity control over antioxidant treatments alone. Based on the chemical measurements rancidity development is retarded best by treatment with the antioxidants ascorbic acid and/or TBHQ in combination with vacuum-packaging.
