Effects of bleeding conditions and storage methods on the quality of Atlantic Cod
The aim of this project was to study, first of all, the effects of iceless storage at -1 °C on the quality of cod fillets (Gadus morhua). Secondly to explore the possibility of starting the cooling process earlier in the processing line by bleeding in cooled bleeding medium as well as the effects of...
