Abstract

The present invention relates to liquid clarification. More closely, the invention relates to beverage clarification, such as reduction of colloidal (not microbial) haze-causing substances in beer or related beverages such as wine, juices, flavorings etc. The method of the invention uses a hydrophilic surface for adsorption of haze-forming substances by hydrogen bonding interaction properties between the surface and the haze-forming substances.
