Sensory quality of Atlantic salmon as affected of fish size and fillet part
The aim of the present study was to investigate the effect of body weight and fillet parts on sensory quality of raw and cooled salmon fillets and consumer preference of cooked salmon fillets. Three groups of salmon with the average body weight of 3991 ± 61g, 5005 ± 54g and 6013 ± 68g respectively w...

Three groups of salmon with the average body weight of 3991 ± 61g, 5005 ± 54g and 6013 ± 68g respectively were filleted.

The odour, flavour, firmness and juiciness correlated significantly to the overall preference while the colour of the cooked fillets had no effect on the overall preference. To conclude, sensory quality differences were observed for both raw and cooked fillets among the three size classes of salmon and among two parts of the same fillets.
