The particle size of different nanoemulsions was about 160–207 nm. The oxidative stability of salmon lecithin was higher than that of other oil samples in spite of its high LC-PUFA concentration. Crude salmon oil was better protected by its natural antioxidants (tocopherols and astaxanthin). In this study, a high concentration of α-tocopherol (0.2 % ) was used for its pro-oxidant role. The addition of quercetin improves slightly the oxidative stability of oils. However, no effect of this antioxidant was observed in emulsion, due to its insolubility in water and lipid phases.
