Microcapsules based on gelatin and low molecular weight anionic polysaccharide which may contain solids or liquids, prepared by coacervation.n n n The aqueous solutions of the polysaccharides which can be used have a low viscosity, the value of which depends on the nature of the polysaccharide; for a concentration of 15 g / l it is, at 75 ° C, generally between 1 and 20 mPa.s.n n n These polysaccharides are depolymerization products of natural products: alginates, carrageenans, pectins and pectates, carboxymethylcelluloses, these carboxymethylguars and carboxymethyl starches.n n n The microcapsules can be isolated and dried. |
