It can adsorb protein to extend beer shelf life: Beer silica gel has large specific surface area and a number of appropriate micro pore structures which can adsorb turbid active protein with the molecular weight of 10-30KD in the beer in few minutes. By filtration, it can extend the beer shelf life and prevent beer cold turbidity without changing the beer foam and taste.
surface area of beer silica gel is big. It has numberless micro pore structure which can adsorb molecular weight 10-30KD turbid active protein in the beer in few minutes. chemical nature of beer silica gel is stable. It does not include any beer solvend. It can be used together with other stabilizer, such as: PVPP, PVP, tannin, papain and isinglass, etc.
