Encapsulation stability of duplex emulsions prepared with SPG cross-flow membrane, SPG rotating membrane and rotor-stator techniques-A comparison

▸ Duplex W1/O/W2 emulsions prepared with high-shear and membrane techniques. ▸ At high shear stress droplet size driven by the rate of interfacial tension decrease. ▸ Lowest salt release from W1/O/W2 occurs during rotating membrane emulsification. ▸ Salt encapsulation is largely compromised by semi-batch cross-flow emulsification.
