Influences of potassium ferrocyanide on lipid oxidation of salted cod (Gadus morhua) during processing, storage and rehydration

► Potassium ferrocyanide as a prooxidant for lipid in salted cod. ► With processing times, lipid oxidation of salted cod significantly develops. ► Yellow discolouration is highly correlated to lipid oxidation. ► Fluorescence compounds are significantly correlated with b∗ value and TBARS. ► Partial lipid oxidation products are removed by rehydration.
