The present invention relates to capsules for the production of coffee from beverages, particularly coffee powders, from beverage powders by the introduction of water, said capsules comprising a pressurized object consisting of a powder containing at least one polysaccharide, Wherein the at least one coating layer comprises a crosslinked polysaccharide and the crosslinked polysaccharide is obtained by crosslinking the polysaccharide with a crosslinking agent without using a polyol spacer. The process for the preparation of such capsules comprises the following steps: i) providing a pressurized article consisting of a powder containing at least one polysaccharide, ii) at least a part of the pressurized object obtained in step i) Contacting the surface with a solution of a polysaccharide in a solvent or a dispersion of a polysaccharide in a dispersing agent, iii) possibly eliminating the solution or a substance which has been pressurized from the dispersion of step ii), iv) the step ii) or iii) Contacting the pressurized material obtained in step iv) with at least one cross-linking agent, v) possibly removing the pressurized material from the solution of step iv), and vi) contacting the pressurized material obtained in step iv) or v) Lt; / RTI > |
