AB Currently, industry is requesting proven techniques that allow the use of encapsulatedpolyphenols, rather than free molecules, to improve their stability and bioavailability. Response surfacemethodology (RSM) was applied in this work to determine the optimal composition and operatingconditions for preparation of water-in-oil-in-water (W/O/W) emulsions loaded with phenolic richinner aqueous phase from olive mill wastewater. A rotor-stator mixer, an ultrasonic homogenizerand a microfluidizer processor were tested in this study as high-energy emulsification methods.Optimum results were obtained by means of microfluidizer with 148 MPa and seven cycles inputlevels yielding droplets of 105.3   3.2 nm in average size and 0.233   0.020 of polydispersityindex.  -potential, chemical and physical stability of the optimal W/O/W emulsion were alsoevaluated after storage. No droplet size growth or changes in stability and  -potential were observed.Furthermore, a satisfactory level of phenolics retention (68.6%) and antioxidant activity (89.5%) after35 days of storage at room temperature makes it suitable for application in the food industry.
