Stabilization treatment method of beer a method of manufacturing the same, and beer stabilization process for silica gel

摘要

PURPOSE: To provide a method for producing silica gel, having high effect for preventing cloudiness of beer and a method for carrying out stabilizing treatment of beer. ;CONSTITUTION: This silica gel is baked at 400-800°C for 10sec to 10hr and has 700-1000m²/g specific surface area, 1.1-1.6ml/g pore volume and 6-10nm average pare diameter and extremely high adsorbing ability per unit weight. The silica gel is produced by reacting a silicic acid salt with an inorganic acid so that SiO₂ concentration becomes 10-20wt.% and subjecting the produced silica hydrosol to gelation, the resultant gel to water washing, hydrothermal treatment with water having pH 2-8 and 20-100°C temperature and acid treatment with an inorganic acid or an organic acid having pH2-5 and pulverizing the treated gel so as to become 5-30μm average particle diameter, drying the gel at 100-1000°C for 1-100sec and baking the gel at 400-800°C for 10sec to 10hr. The component which becomes the cause of cloudiness can be removed in high efficiency from beer by bringing the silica gel into contact with beer and separating the silica gel from the beer.;COPYRIGHT: (C)1996,JPO
