  • Manufacturing Process for Polysaccharide Beads
    Publication number: 20220106462
    Abstract: The invention discloses a method of manufacturing polysaccharide beads, comprising the steps of: i) providing a water phase comprising an aqueous solution of a polysaccharide; ii) providing an oil phase comprising at least one water-immiscible organic solvent and at least one oil-soluble emulsifier; iii) emulsifying the water phase in the oil phase to form a water-in-oil (w/o) emulsion; and iv) inducing solidification of the water phase in the w/o emulsion, wherein the organic solvent is an aliphatic or alicyclic ketone or ether.
    Type: Application
    Filed: December 14, 2021
    Publication date: April 7, 2022
    Inventors: Per Erik Emilsson, Susanna Klara Margareta Lindberg, Jonny Wernersson, Jonas Gustafsson, Adam Hurynowicz
