Title (EN) CAPSULES AND PROCESS FOR THEIR PREPARATION
(FR) CAPSULES ET LEUR PROCEDE DE PREPARATION
Abstract: front page image
(EN)Capsules are prepared by bringing a fluid containing a polyanion polysaccharide or its salt as a base into contact with a solution of a soluble chitin derivative solution, particularly chitosan to form a gel membrane around the fluid. Since the capsules are formed under biological, i.e. mild conditions, capsules containing an unstable biological substance in the core solution can be provided.
(FR)Des capsules sont préparées em mettant un fluide contenant un polysaccharide polyanionique ou son sel en tant que base en contact avec une solution d'un dérivé soluble de chitine, notamment de chitosan pour former une membrane de gel autour du fluide. Etant donné que les capsules sont formées dans des conditions biologiques, c'est-à-dire "douces", il est possible de produire des capsules contenant une substance biologique instable dans la solution de noyau.
