Title
(EN) A PROCESS FOR PREPARING CURCUMIN ENCAPSULATED CHITOSAN ALGINATE SPONGE USEFUL FOR WOUND HEALING
(FR) PROCÉDÉ DE PRÉPARATION D'UNE ÉPONGE D'ALGINATE ET DE CHITOSANE ENROBÉE DE CURCUMINE UTILE POUR LA CICATRISATION DES PLAIES
Abstract
(EN)
A process for preparing curcumin encapsulated chitosan alginate sponge comprising the steps of: incorporating curcumin in a fluid phase of oleic acid; subjecting the mixture to a step of emulsification with chitosan solution by homogenization; emulsifying the resultant solution with alginate solution by homogenization; lyophilizing the final emulsion by freeze drying to produce curcumin loaded AC sponge.
(FR)
L'invention concerne un procédé de préparation d'une éponge d'alginate et de chitosane enrobée de curcumine, ce procédé consistant à : incorporer de la curcumine dans une phase fluide d'acide oléique; soumettre le mélange à une étape d'émulsification avec une solution de chitosane par homogénéisation; émulsifier la solution obtenue avec une solution d'alginate par homogénéisation; lyophiliser l'émulsion finale par cryodessiccation pour produire une éponge d'alginate et de chitosane chargée de curcumine.
