...Dr. Karl Raible developed the first silica gel for protein stabilization of beer which was introduced to the brewing industry in 1961. In the same year a patent was applied for at the German Patent Office and granted with the German patent number 1160812. Similar patent applications then followed worldwide. Since then the practice of using silica gel in the process of stabilization has become established throughout the world. The first protein stabiliser based on silicic acid was launched under the trade name STABIFIX by BRAUEREI-TECHNIK, Munich, which still remains one of the best-known suppliers of brewery silica gel the world over, and the name STABIFIX is often used as a synonym for brewery silica gel.
