Definitions

  • the present invention relates to a beverage powder-containing capsule, which is particularly suitable for the preparation of a beverage, such as cocoa, tea or coffee.
  • coffee capsules In the portion-wise preparation of beverages, in particular brewed coffee, coffee capsules have been increasingly used in recent years in addition to coffee pods whose capsule walls are usually made of stainless steel, aluminum or plastic. Such capsules allow to store coffee powder over a longer period of time without appreciable loss of flavor. In addition, such capsules allow a quick and user-friendly production of a portion of coffee with the desired flavor by a capsule of the desired coffee is used in a customized coffee machine in which then hot water is pressed through the capsule and brewed coffee is produced from it.
  • capsules are comparatively expensive due, inter alia, to the capsule material used and the production-intensive capsule construction.
  • such capsules are environmentally problematic. First, the capsules are not recyclable and are disposed of by the consumer after use usually as residual waste.
  • capsules of alternative materials have already been proposed.
  • capsules which are filled with coffee or tea in their interior and comprise a capsule wall which, in addition to the capsule contents, also contains water as structuring component.
  • a capsule wall which, in addition to the capsule contents, also contains water as structuring component.
  • the capsule be cooled below the freezing point of the structuring component because the structuring component melts when it exceeds its freezing point and wets the capsule contents. This naturally limits the use of such capsules considerably.
  • WO 2009/053811 A2 describes a capsule that may contain ground coffee, cappuccino powder, chocolate powder, milk powder or tea powder.
  • the capsule comprises two half-shells, which form the capsule walls.
  • the capsule walls consist of a water-soluble material which dissolves during the brewing process. In this concept, the capsule wall material is dissolved during the brewing process and thus part of the prepared drink, which may affect the taste undesirable.
  • the WO2014 / 161653 discloses a capsule, in particular for preparing a beverage from beverage powder, in particular coffee from coffee powder, by introducing water into the capsule, from a capsule body composed of at least one polysaccharide filled with a polysaccharide-containing powder, wherein the capsule body with at least one Coating layer is coated. Proceeding from this, the present invention seeks to provide a capsule for the portionwise preparation of beverage from beverage powder, such as cocoa, tea and coffee, which is not only easy and inexpensive to produce, but which in particular biodegradable and therefore environmentally friendly is to dispose of the capsule contents also over a stored for a prolonged period without appreciable loss of flavor and can be used depending on the design in different beverage vending machines.
  • beverage powder such as cocoa, tea and coffee
  • this object is achieved by a capsule, in particular for preparing a beverage from beverage powder, in particular coffee from coffee powder, by introducing water into the capsule, from a capsule body composed of at least one polysaccharide, which is filled with a polysaccharide-containing powder the capsule body is coated with at least one coating layer, the at least one coating layer comprising a crosslinked polysaccharide, the crosslinked polysaccharide being obtained by crosslinking a polysaccharide with a crosslinking agent.
  • This solution is based on the finding that such a capsule of a capsule body composed of at least one polysaccharide coated with at least one cross-linked polysaccharide coating layer not only has all the necessary properties for its use in the portion-wise preparation of beverages, such as Coffee, are required, but in particular also environmentally friendly disposable.
  • the capsule body with the at least one coating layer made of a cross-linked polysaccharide is stable enough to provide the capsule with a sufficiently high transport protection and grip protection.
  • the capsule can thereby absorb even high pressures, such as may occur during the preparation of a brewing beverage.
  • the capsule according to the invention protects the capsule contents on account of the at least one coating layer of a cross-linked polysaccharide even over a relatively long period of time without a noticeable loss of flavor occurring.
  • the coating layer seals the surface of the normally air-permeable capsule body of polysaccharide.
  • the coating layer of a crosslinked polysaccharide acts as an additional oxygen barrier.
  • the combination of Capsule body with the coating layer of cross-linked polysaccharide thus leads to a preservation of the aroma of the capsule contents.
  • Another advantage of the capsule according to the invention is that neither the capsule body nor the at least one coating layer dissolves during the beverage preparation and thus does not cause a falsification of the taste of the prepared beverage.
  • the capsule according to the invention is simple and inexpensive to produce. It is also particularly important that both the capsule body and the at least one coating layer of cross-linked polysaccharide are completely biodegradable and therefore environmentally friendly to dispose of. Since polysaccharides are not of fossil and non-synthetic origin and their recovery is comparatively less energy-intensive, the capsule according to the invention has an advantageous CO 2 balance.
  • the present invention is not limited in the chemical nature of the polysaccharide of the at least one coating layer.
  • the polysaccharide of the at least one coating layer is selected from the group consisting of starch, cellulose, chitin, carrageenan, agar and alginates.

  • these polysaccharides do not cause a falsification of the taste during the preparation of the beverage.
  • capsule bodies of polysaccharide can be coated with alginate in a simple and cost-effective manner.
  • alginates are biodegradable and provide a sufficiently stable sheath and protect the capsule contents, without a significant loss of flavor occurs.
  • alginates are capable of lowering the water hardness. In addition, an unpleasant acid taste is prevented or at least mitigated.
  • the polysaccharide of the at least one coating layer is crosslinked.
  • the crosslinking of the polysaccharide according to an embodiment of the present invention can take place via covalent bonds.
  • Crosslinking via covalent bonds allows very durable sheaths.

  • Particularly suitable cross-linking agents are difunctional organic compounds, where the functional groups are selected, for example, from the group consisting of carboxylic acids, salts of carboxylic acids, activated carboxylic acids, amines, alcohols, aldehydes and ketones.
  • Activated carboxylic acids in this context are understood as meaning carboxylic acid halides, active esters of carboxylic acids, anhydrides of carboxylic acids or other reactive derivatives of carboxylic acids.

  • the polysaccharide of the at least one coating layer is crosslinked via ionic and / or coordinative bonds.
  • Such crosslinked via ionic and / or coordinative bonds polysaccharides are particularly easy to produce and do not affect the biodegradability of the polysaccharide used.
  • the ionic and / or coordinative crosslinking can be achieved, for example, by means of polysaccharides which have anionic groups, such as carboxylate groups or sulfonate groups.

Subsequent coating layers are preferably thinner and are preferably between 40 and 200 microns to allow rapid drying.
  • a thin coating layer is preferred in order to more easily remove the water contained in the gel and, in order to allow the crosslinking agent to diffuse as quickly of calcium ions, to facilitate sodium alginate.
  • the rate of diffusion of the calcium ions into the sodium alginate could also be increased by a higher concentration of the crosslinking agent;
