The invention relates to a capsule, in particular for preparing a beverage from beverage powder, in particular coffee from coffee powder, by introducing water into the capsule, which capsule comprises a pressed article composed of a powder containing at least one polysaccharide, wherein the pressed article is coated with at least one coating layer, wherein the at least one coating layer comprises a cross-linked polysaccharide, wherein the cross-linked polysaccharide was obtained by cross-linking a polysaccharide by means of a cross-linking agent without using a polyol spacer. A method for producing such a capsule comprises the following steps: i) providing a pressed article composed of a powder containing at least one polysaccharide, ii) bringing at least part and preferably the entire surface of the pressed article obtained in step i) in contact with a solution of a polysaccharide in a solvent or with a dispersion of a polysaccharide in a dispersant, iii) possibly removing the pressed article from the solution or the dispersion of step ii), iv) bringing the pressed article obtained in step ii) or iii) in contact with at least one cross-linking agent, v) possibly removing the pressed article from the solution of step iv), and vi) drying the pressed article obtained in step iv) or v).
