Method for stabilising protein- and tannin-containing beverages and apparatus for carrying out this method

摘要

In a method for stabilising protein- and tannin-containing beverages, in particular beer, the partially electropositively charged proteins (10) are separated out at the cathode (3) and the partially electronegatively charged polyphenols (11) are separated out at the anode (5) of an electrophoresis cell (1) having at least one semipermeable membrane (2). In order in this case to prevent oxidation of the beverage, the beverage to be stabilised is passed through the space between cathode (3) and semipermeable membrane (2). <IMAGE>
