Protein phosphorylation profile of Atlantic cod ( Gadus morhua ) in response to pre-slaughter pumping stress and postmortem time
This study aimed to evaluate the effect of pumping stress (pumping and pumping-resting) and postmortem time (before and after rigor mortis) on phosphorylation profiles of myofibrillar protein (MP) and sarcoplasmic protein (SP) of Atlantic cod (Gadus morhua) fillets. The result showed that MP had hig...
