Method for obtaining biodegradable colloidal particles

Abstract

The present invention relates to a system for the release of bioactive compounds comprising biodegradable colloidal particles with an average size less than 500 nm, where the biodegradable colloidal particles comprise an anionic polysaccharide and a cationic polysaccharide. Furthermore, its method of extraction includes: (a) estimating the stoichiometric charge ratio between an anionic polysaccharide, and a cationic polysaccharide; (b) preparing a solution with the anionic polysaccharide based on the stoichiometric charge ratio and adjusting to an acidic pH; (c) preparing a solution with the cationic polysaccharide based on the stoichiometric charge ratio and adjusting to an acidic pH; (d) adding the solution with the cationic polysaccharide to the solution with the anionic polysaccharide to obtain biodegradable colloidal particles; (e) reducing the particle size of the biodegradable colloidal particles; (f) separating the biodegradable colloidal particles from the supernatant; and (g) resuspending the biodegradable colloidal particles and storing them.
