MICROCAPSULES BASED ON GELATIN AND POLYSACCHARIDES AND PROCESS FOR OBTAINING SAME

摘要

IN THE CANADIAN PATENT /A TRADEMARK OFFICE PATENT APPLICATION entitled : Microcapsules based on gelatin and poly saccharides and process for obtaining same in the names of : Jacky DAVID Claudine LEFRANCOIS Claude RIDOUX assigned to : MERO ROUSSELOT SATIA This invention relates to microcapsules based on gelation and anionic polysaccharides of low molecular weight which may contain solid or liquid matters, prepared by coacervation. The aqueous polysaccharide solutions which may be used present a low viscosity, the value of which is a function of the nature of the polysaccharide ; for a concentration of 15 g/l, it is, at 75.degree.C, generally included between 1 and 20 mPa.s. These polysaccharides are depolymerization products of natural products : alginates, carragheenans, pectins and pectates, carboxymethylcelluloses, carboxymethylguars and carboxymethyl starches. The microcapsules may be isolated and dried.
