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) and vi) drying of the compacted pellet obtained in step iv) or v).
A capsule, in particular for preparing a beverage from beverage powder, in particular 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 the cross-linking of a polysaccharide with a cross-linking agent without the use of a polyol spacer.
The capsule according to one of the preceding claims, characterised in that the polysaccharide of the at least one coating layer is cross-linked via covalent bonds.
The capsule according to one of the preceding claims, characterised in that the compacted pellet is sheathed with 1 to 100 coating layers;
The capsule according to one of the preceding claims, characterised in that the compacted pellet contains or is preferably composed of a material selected from the group consisting of coffee, tea, drinking chocolate, cocoa and milk powder.
The capsule according to one of the preceding claims, characterised in that the compacted pellet can be obtained by pressing the powder with a pressure of 0.01 to 1000 MPa, preferably 0.05 to 500 MPa, particularly preferably 0.1 to 100 MPa, even more preferably 0.5 to 100 MPa, still more preferably 1 to 100 MPa, more particularly preferably 5 to 50 MPa, and maximally preferably 15 to 30 MPa.
A method for manufacturing a capsule according to any one of the preceding claims, comprising the following steps:
