Conventional emulsification techniques lead to polydisperse emulsions. Droplet size is difficult to control and the shear imposes a high strain on the liquids, which may result in biocompounds activity losses (Charcosset, 2009). Membrane emulsification (ME) reduces the strain on the liquid phases, and gives a narrower droplet size distribution with less shear stress and energy consumption. Hence, ME should have a favourable effect on the resulting encapsulation efficiency.
