Membrane Emulsification: Principles and Applications

Polycaprolactone multicore-matrix particle for the simultaneous encapsulation of hydrophilic and hydrophobic compounds produced by membrane emulsification and solvent diffusion processes

“…Therefore, modification of the laboratory method, or the development of new techniques, is necessary [16]. Membrane emulsification is an extremely effective technique to meet these requirements.The formation of highly uniform droplets [17] as well as the low energy density of the process compared to conventional mechanical methods [18], provides the encapsulation of labile molecules in particulate systems with controlled size keeping their quality and functionality. The mild conditions of membrane emulsification are especially useful when the microencapsulation process involves the preparation of a W/O/W emulsion as an initial liquid phase.This kind of emulsion is highly thermodynamically unstable and emulsion breakdown can occur easily in the high shear stress conditions.…”

“…Here droplets are produced individually in a single step when the dispersed phase is pressed through a microporous membrane. Then droplets are formed on the other side of the membrane that is in contact with the continuous phase at the opening of each pore [21][22][23]. Once the droplets reach critical dimensions they detach into the continuous phase either due to spontaneous deformation driven by free-energy minimization or through shearing generated by a continuous phase flow over the membrane surface [22].…”
