METHOD AND APPARATUS FOR THE PREPARATION OF A FERMENTED BEVERAGE WITH REDUCED ALCOHOL CONTENT

摘要

A method is described of producing a fermented drink having a reduced alcohol content. A fermented drink produced according to a conventional fermentation method is passed along a dialysis membrane at a pressure difference of less than 5.0 bars, while a dialysate liquid flows simultaneously on the other side of the dialysis membrane. The fermented drink may be subjected both to dialysis and to ultrafiltration. The dialysate liquid may contain extractive substances of the fermented drink, for example, the dialysate liquid may be a non-alcoholic, fermented drink which corresponds to the drink to be dialysed, the alcohol having been removed from the dialysate liquid by adsorption, extraction, reverse osmosis and/or distillation.
