To remove selectively particularly sugar from nonalcoholic or alcoholic beverages, first the sugar is either carried away in the permeate in a membrane separation unit (2) by suitable choice of membrane (4) or is retained in the retentate. Afterward, the sugar is removed from the permeate or from the retentate with the help of a device (5) for substance removal or substance conversion. Next the substances remaining in the permeate or in the retentate after the removal of the sugar are fed back into the process or the final product. With the process according to the invention, a high selectivity and an improvement in quality of the final product with high economic efficiency of the unit is achieved (FIG. 1).
