摘要： A process for separating caffeine from an aqueous raw coffee extract by means of gel chromatography is described, in which simultaneously the chlorogenic acids can be separated if desired. The inventive process makes it possible to obtain in a simple manner decaffeinated coffee, optionally with a reduced chlorgenic acid content.

摘要： A device for continuously decaffeinating raw coffee includes a first extractor having at least one cell for use in a first treatment stage where raw coffee is preswollen by a swelling fluid that is added to the raw coffee. The at least one cell receives the raw coffee that is to be preswollen and is defined by a bottom and a plurality of sidewalls that extend towards one another to define a wedge-shaped cell. Additional similarly shaped cells and receiving chambers positioned below the cells may also be provided with a perforated bottom separating each cell from its respective receiving chamber.

摘要： In the decaffeination of green coffee beans with an aqueous medium, caffeine is removed from the aqueous medium which also contain non-caffeine green coffee solids, contact with substantially neutral active carbon. Thereafter the medium may be recycled to extract further amounts of caffeine from the same or another batch of green coffee beans.Other features of the invention are described in the specification.

摘要： A method and a device for making a coffee beverage are provided. The method includes: heating coffee powder by water vapor at a temperature lower than a sublimation temperature of caffeine to sublimate a volatile fat component in the coffee powder without sublimating the caffeine, and dissolving other water-soluble components in water at a temperature lower than 85° C. while only dissolving a little of the caffeine.
