  • Effects of chilled storage on quality of vacuum packed meagre fillets
    Publication . Genç, Ísmail Yüksel; Esteves, E.; Aníbal, J.; Diler, Abdullah
    The aim of this study was to experimentally assess several quality indices of meagre Argyrosomus regius (Asso, 1801) fillets packed in air (AP) and vacuum (VP) stored chilled (+4 C) for up to 13 days. Considering our experimental data on concentration of bacterial counts, shelf-life is estimated at ca. 6 days for AP fillets and an additional 3–5 days for VP meagre fillets. Total volatile basic nitrogen (TVB-N) and trimethylamine (TMA-N) did not reach the regulated limits (25–35 mg/100 g chilled fish). The models implemented in the software Seafood Spoilage and Safety Predictor predicted a relatively shorter shelf-life of 4.8–6.9 days for fish stored in air at +4 C when compared to AP and VP fillets. Empirical data and the models implemented in the software were used to predict the shelf-life of fillets if packaged under different modified atmospheres (MAP). Chilled, MAP fillets are likely to have a longer shelf-life than AP or VP samples if equilibrium CO2 concentration is substantially high.

  • Effects of different thawing methods on the quality of meagre fillets
    Publication . Genç, Ísmail Yüksel; Esteves, E.; Aníbal, J.; Diler, Abdullah
    The aim of this study was to determine the effect of different thawing methods (air, refrigerator, water and microwave) on physical, chemical and microbiological quality of meagre fillets which were frozen and stored at -20°C for 21 days. The samples were compared for colour changes, pH, total volatile basic nitrogen (TVB-N), hardness, adhesiveness, total viable count (TVC), total psychrophilic count (TPC) and hydrogen-sulphide producing bacteria (H2S). In terms of hardness, refrigerator thawed samples exhibited a harder texture compared to other ones. Taking into account all parameters studied, refrigerator thawing was found to be more suitable for the frozen meagre fillets.
