droplets produced by premix membrane emulsification using surfactant-displacement and/or
electrostatic deposition methods. The non-ionic surfactant Tween 20 is particularly effective at
producing uniformly sized lipid droplets by premix membrane emulsification, but the droplets
produced have a low net charge. The interfacial characteristics of emulsion droplets initially
coated by Tween 20 could be made either negative or positive (without altering droplet size) by
adding controlled amounts of either anionic emulsifiers (SDS) or cationic emulsifiers (DTAB or
β-lactoglobulin) to the continuous phase after homogenisation. In addition, cationic emulsion
droplets could be prepared by depositing a cationic biopolymer (chitosan) onto the surfaces of
anionic droplets (SDS/Tween coated). These results have important consequences for the design,
fabrication and utilisation of uniformly sized lipid droplets with controlled interfacial
characteristics.
