Abstract
The present invention relates to a method for the removal of polyphenols and proteins simultaneously from a beverage by contacting the beverage with an ion exchanger that is capable of adsorbing both types of substances. The characteristic feature of the ion exchanger to be used is that it is a water-insoluble porous hydrophilic matrix to which ion exchanging groups are covalently bound.
