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.
