Special silica sol of exceptional purity and activity for the fining of beverages. It is used in combination with gelatin or other positively charged fining agents as a flocculation intensifier.
Silica sol fining agent (BEVASIL® 30 or Levasil® 200/30% FG) is a transparent, slightly opalescent aqueous silicic acid solution and contains 30% colloid silicon dioxide (SiO2). The possibility of using the water insoluble, amorphous silicon dioxide as "aqueous solution" is achieved by colloid distribution.
The beverage treatment with silica sol fining agent and SIHA® Gelatin results in an economical and taste neutral clarification. A taste improvement is also often attained. Even in difficult cases, the clarification of the beverage is accelerated; the turbidity deposit becomes more compact and beverage losses, filtration time and the use of filtering agents are reduced.
Silica sol fining agent is regularly monitored during the production process to ensure consistent high product quality. Strict controls are undertaken before and during final packaging.
