The effect of diets supplemented with thyme essential oils and rosemary extract on the deterioration of farmed gilthead seabream (Sparus aurata) during storage on ice

► Farmed gilthead seabream were administered feeds supplemented with aromatic plant oils and extracts. ► The effects on postmortem quality during storage on ice were assessed. ► Animals fed diets with BHT, carvacrol and rosemary showed lower oxidation levels. ► The antibacterial effect of thymol was higher than in the rest of the groups. ► Deterioration in terms of sensory perception was slower with BHT and thymol.
