AB Wheat bran oil (WBO) has been reported to have an important content of bioactive compounds, such astocopherols, alkylresorcinols, steryl ferulates and other phenolic compounds; however, its poor solubilityin water systems restricts its applications in the food industry. This study is focussed on the formulationof oil-in-water (O/W) nanoemulsions of WBO in order to improve the bioaccessibility of its active compounds.The influences of oil concentration, surfactant type and concentration, and emulsificationmethod, on the droplet size and stability of the nanoemulsions were investigated. Response surfacemethodology was used to optimise the conditions for preparing stable nanoemulsions with the minimumdroplet size. The optimal nanoemulsion was obtained when 1% of WBO and 7.3% of a surfactant mixtureof Span 80 (37.4%) and Tween 80 (62.6%) were emulsified in water by high intensity ultrasonication for50 s after pre-emulsification with a high speed blender during 5 min. The optimal nanoemulsion showedgood stability over time and antioxidant and tyrosinase inhibitory activities, which make it suitable foruse in food applications.
