Preparation and Characterization of Oilcontaining Microparticles

Abstract

Oilfree as well as oilcontaining microparticles based on gelatin and gelatin-Acacia-systems respectivly are produced by preparing a “multiple emulsion” using the simple coacervation. The characterization of the particles points out relationships between the content of polyunsaturated fatty acids and the mean diameter, the oil content and the shape of the surface. Both, the ratio between oil-colloid-emulsion and external phase and the viscosity of this phase have some influence on the mean size of the microparticles.
