Encapsulation of active ingredients

Microspheres having a particle size of 50 nm to 1 nm and a polydispersity of less than 40%, consisting of a chemically cross-linked starch shell containing an active ingredient, are obtained by preparing an oil-in-water emulsion of the active ingredient in a hydrophobic phase and starch or a dispersion of a solid active ingredient and starch in water, incorporating the oil-in-water emulsion or solid dispersion in an outer hydrophobic phase, particles of the oil-in-water emulsion or solid dispersion being formed in the outer hydrophobic phase, cross-linking the starch or derivative thereof and removing the outer hydrophobic phase if desired.
