Abstract: The present invention relates to products from porous materials, generated by foaming with gas hydrates or gas hydrate slurries dosed into matrices of biological, organic or inorganic materials in their liquid to paste-like state. A method of producing a water phase continuous slurry comprising gas hydrates, a method of producing a porous powder or foam as well as the use of gas hydrates for producing a porous powder or foam or for gasifying viscous liquid are also claimed. The porous powder or viscous foam, wherein the powder or foam has a closed porosity of 15% to 100%, or 20% to 50%, or 25% to 35%, or 30 to 35%, or about 30%.

Abstract: The present invention relates to an instant coffee powder, wherein the powder has a closed porosity of 15% to 50%, or 20% to 35%, or 25% to 34%, or 30 to 34%, or about 30%; use of gas hydrates for producing an instant coffee powder; and a method of producing an instant coffee powder.

Abstract: Use of a gas hydrate for producing a frozen food foam product, wherein the gas comprises air and/or one or more of carbon dioxide, nitrogen, nitrous oxide, argon and oxygen, preferably the gas comprises carbon dioxide and/or nitrogen.
