Abstract:
A process for the production of nanocapsules or nanoparticles, said nanocapsules or nanoparticles having a size less than 1 micron, said nanocapsules or nanoparticles having crosslinked protein-based walls, which process comprises preparing a nanoemulsion of at least one acylatable group-containing protein, said emulsion comprising a water phase, an oil phase, defining an interface between said water phase and said oil phase either of a water-in-oil emulsion or an oil-in-water emulsion, and forming said nanocapsules or nanoparticles from said nanoemulsion, wherein an interfacial crosslinking reaction is carried out, between said protein and a crosslinking agent having reactive groups capable of reacting at said interface with said acylatable groups of said protein, so as to yield said nanocapsules or nanoparticles with crosslinked protein-based walls.
