A capsule, especially for preparing a beverage from beverage powder, in particular of coffee from coffee powder, by introducing water into the capsule, wherein the capsule comprises a compacted pellet made of a powder containing at least one polysaccharide, wherein the compacted pellet is sheathed with at least one coating layer, wherein the at least one coating layer comprises a cross-linked polysaccharide, wherein the cross-linked polysaccharide can be obtained by cross-linking a polysaccharide with a cross-linking agent without the use of a polyol spacer.A method for manufacturing such a capsule comprises the following steps:i) preparing a compacted pellet from a powder containing at least one polysaccharide,ii) bringing at least one part and preferably the entire surface of the compacted pellet used in step i) into contact with a solution of a polysaccharide in a solvent or with a dispersion of a polysaccharide in a dispersant,iii) when appropriate, removing of the compacted pellet from the solution or dispersion of step ii),iv) bringing the compacted pellet obtained in step ii) or iii) into contact with at least one cross-linking agent,v) when appropriate, removing the compacted pellet from the solution of step iv) andvi) drying of the compacted pellet obtained in step iv) or v).
