Effects of controlled thawing media temperatures on quality and safety of pre-rigor frozen Atlantic cod (Gadus morhua)
Novel strategies for thawing of pre-rigor frozen Atlantic cod (Gadus morhua) in water with air circulation, applying different and controlled temperatures are presented. After thawing (day 0) and after six days of storage at 2.9 ± 0.6 °C (day 6), quality parameters (thawing- and drip loss, cooking y...
