Auxiliary agents for the beverage industry

The use of auxiliary agents can significantly extend the shelf life of beer. This essentially involves reducing the content of polyphenols and tannins by adding PVPP, silica gel or activated carbon. Depending on the desired clarity of the beer and targeted shelf life, it may be helpful to use a combination of several auxiliary substances.

Special activated carbons are suitable for removing unpleasant odours or tastes in beer, for treating the brewing liquor and for correcting organoleptic faults.

Stabilizers

Stabilizers are used to remove turbidity that may result from proteins or yeasts and other suspended particles from the beer. In this way beer is stabilized both in microbiological and in chemical/physical terms.

Our supply range includes:

PVPP (Polyvinylpolypyrrolidone)

This primarily removes phenolic compounds.

Silica gels

Our range includes both xerogels and hydrogels. These products consist of ultra pure amorphous silicon dioxide and are exceptionally suitable for stabilizing beer.

Silica brines

Liquid stabilizing agents based on high-purity amorphous silicon dioxide.
