Capsule containing beverage powder, in particular for preparing brewed coffee

Abstract

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 comprisesa 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 comprisesa 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 pressedarticle 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).

Description

technical field [0001] The present invention relates to a capsule containing a beverage powder, which is particularly suitable for preparing beverages such as cocoa, tea or coffee. Background technique [0002] In the past few years, besides coffee pads, coffee capsules have been increasingly used for the batch preparation of beverages, especially brewed coffee; the capsule walls are usually made of stainless steel, aluminum or plastic. Such capsules are able to store ground coffee for a considerable period of time without loss of taste. In addition, such capsules enable a quick and user-friendly preparation of a portion of coffee with the desired taste, wherein the capsules containing the desired type of coffee are placed in a coffee machine suitable for the purpose, in which hot water is then pressed to make It passes through the capsule, thereby making the desired brewed coffee. However, such capsules are relatively expensive due to the capsule material used and the int...

Problems solved by technology

In this concept, the capsule wall material dissolves during brewing and thus becomes part of the prepared beverage, which may undesirably affect the taste

Besides, the production of such capsules is complex and expensive
