  • Patent number: 6565905
    Abstract: There is proposed a silica gel for preventing the generation of haze in beer, a method of manufacturing the silica gel and a method of stabilization treatment of beer. The silica gel is provided with a specific surface area of 700-1000 m2/g, a pore volume of 1.1-1.6 ml/g and a average pore diameter of 6-10 nm, and has a relatively high adsorbability per unit weight. In the method of manufacturing the silica gel, the washed, hydrothermally treated, acid treated, ground and dried silica hydrogel is calcined at 400-800° C. for 10 seconds to 10 hours. A haze causing component can be removed from beer by contacting the silica gel with the beer and subsequently separating the silica gel from the beer.
