Especially, the composition of both hydrophilic and lipophilic phases, their weight ratio, the dry matter content and oil droplet size distribution of the emul- sion and its viscosity were found to be key parameters for aroma encap- sulation [7–11]. Different studies have shown that the decrease of the emulsion oil droplets size (down to 2 μm) causes an increase of the encapsulation efficiency, e.g., a better retention of the active molecule during spray drying, a lower quantity of non encapsulated oil on the par- ticle surface or a better protection of the oil phase regarding oxidation [12,13]. The initial emulsion oil droplet size distribution is therefore a key parameter to control. The choice of the carrier materials that will con- stitute the dry solid matrix is also important
