More Information
Summary:The present invention provides a method for preventing or reducing haze development in a beverage. Silane-treated silica filter media are synthesized. By contacting the beverage with the silane-treated silica filter, one or more haze-forming components bind to the silane-treated silica filter media and are removed by filtration. In addition, particulates in the beverage are removed by filtration. Beverages that tend to develop haze on standing and/or chilling such as alcoholic, fruit, and vegetable beverages, are suitable for the present invention. This haze in a beverage is mainly caused by polyphenols and proteins. The present invention provides a method that can reduce the levels of both polyphenols and proteins. The silica filter media useful for the present method include rice hull ash, oat hull ash, or diatomaceous earth.
