Adsorption system and method for operating an adsorption system

The invention relates to an adsorption system (10) for accumulating flavoring substances, comprising at least one working chamber (12) in which at least one sorption agent is provided as a stationary phase and can be subjected to a flavoring substance-containing fluid which can be conducted through the working chamber as a mobile phase for attaching flavoring substances, wherein the flavoring substance-containing fluid is a food item from the group of beer-containing staple and/or luxury food items, beer wort, hops, hop extract, malt water, malt beer, malt wort and brewery-specific ingredients and products and/or is obtained by means of a dealcoholizing device from an ethanol-containing food item from the group of beer-containing staple and/or luxury food items, wherein a ratio of an average cross-sectional thickness to the total length of the at least one working chamber (12) is at most 0.3. The invention also relates to a method for operating such an adsorption system (10), a flavoring substance concentrate and a deflavored permeate which can be and/or are obtained by means of such an adsorption system (10) and/or by means of such a method from a flavoring substance-containing fluid, as well as to a beer which can be or is obtained by mixing an at least partially dealcoholized and/or fermentation-halted beer having such a flavoring substance concentrate.
