Abstract

Det beskrives en fremgangsmåte for fremstilling av vannoppløselige chitosansalter, chitosanprodukter fremstilt ved denne fremgangsmåte og anvendelse av disse produkter, f.eks. i farmasøytiske eller veterinærpreparat eller som nærings- eller kosmetisk additiv. Spesielt beskrives det en fremgangsmåte for fremstilling av et vannoppløselig chitosansalt som omfatter: (a) å bringe et fast chitosan i kontakt med minst en protisk syre for derved å gi et vannoppløselig chitosansalt; og (b) eventuelt å gjenvinne saltet, der chitosanet er konvertert til nevnte salt under bibeholdelse av i det vesentlige den faste tilstand.Det kan benyttes gassformige eller flytende protiske syrer inkludert salt-, eddik-, og propionsyre
