2-Octyldodecanol(ODD) has been encapsulated using complex coacervation of biopolymers, gelatin and gum arabic. Gelatin-gum arabic microcapsules have been formed through direct homogenization which generally have a non-uniform size, low encapsulation efficiency. These drawbacks led to controlling the structure of microcapsules difficult, which remains unsolved. Herein, we introduce fluidic device process with triple nozzles. Uniform sized gelatin-gum arabic capsules with one core-one shell were fabricated in oil-in-water-in-oil (O-W-O) double emulsion system. With presented system, size of O-W-O emulsion, diameter of core, and thickness of shell can be controlled with adjusting middle phase flowrate. |
