  • Patent number: 11230687
    Abstract: Producing a dealcoholized beverage from its alcoholic beverage starting product and plant for implementing the method, which comprises the following steps: separating the beverage starting product into an alcoholic and aromatic permeate and into an aromatic and almost alcohol-free retentate in a permeation module by non-thermal permeation, dealcoholizing the permeate in a module intended for that task, and finally mixing the dealcoholized permeate with the almost alcohol-free retentate in a final-mixing module. Prior to the dealcoholizing, aroma compounds are removed from the aromatic and alcoholic permeate by cold adsorption in an aroma adsorber, resulting both in an aroma phase and in an aroma-free but alcoholic permeate which, however, has the alcohol removed from it by alcohol separation, resulting in an aqueous, largely dearomatized and dealcoholized permeate water phase.
