There is a simple and clear answer to turbidities, flavor and (heavy) metals. BASF’s Divergan® range! Special Divergan® types help you to create beverages with reduced polyphenol, haze and (heavy) metal content. Easily. Efficiently. Economically.
BASF offers a wide range of products for filtration and stabilization of beer, wine and other beverages: Create products that fulfill all of your customers’ demands for a crystal clear beverage.
Divergan® is BASF’s standard excipient for the filtration and stabilization of beer and wine. Even after filtration, clear beverages contain dissolved phenolic compounds and proteins that, after a relatively short time, form complexes that subsequently lead to turbidity. Divergan® virtually removes phenolic compounds, and even heavy metal ions, without altering the character of your beer or wine. BASF produces Divergan® by popcorn polymerization of PVP. It is insoluble in water, acids, bases, and organic solvents.
BASF offers you traditional German brewing expertise combined with knowledge and competence in filtration and stabilization. The result: improved clarity and stability, great appearance, pure taste, and long shelf life.
We offer a diverse range of products tailored to your application needs. While our major applications are beer and wine, we offer further applications such as fruit juice and tea. Depending on the manufacturing conditions, coarse or fine grain products are obtained, which differ in their application properties. Divergan® is available as coarse Divergan® RS for beer, and as fine Divergan F® for beer and wine. Special Divergan® types for single and multiple use are available. Choose from a diverse range of products tailored to your application needs.
Divergan® is used for filtration and stabilization of beverages, and create stable, visually appetizing, long-lasting beers, wines, and beverages with an exquisite taste.
Divergan® RS was specifically developed for use in stabilization and regeneration plants. In normal practice, Divergan® RS is added to the beer from a separate metering vessel after diatomaceous earth (kieselguhr) filtration, and separated from the beer in the PVPP filter. The regeneration subsequently occurs in this filter. The small losses arising from regeneration (approximately 1% or less) ensure very low beer stabilization costs. An optimal particle size distribution with low fine-grade fraction, the guaranteed low swelling volume, the high mechanical stability and a qualified technical on-site service ensures trouble-free filtration over an extended period.
*The dosage depends on many factors, such as raw-material quality, cellar technology, pre-clarification, other stabilization methods, desired shelf life, etc...
Normal dosages, in the range of 20–50 g/hl, are recommended. With comparable colloidal stability, the PVPP dosage can be reduced to 15–40 g/hl with silica-gel pre-stabilization. Due to the generally lower polyphenol content, beers with approximately 30% raw-particle fraction require a lower PVPP dosage. When pre-stabilizing with, e.g., silica gel, 15–35 g/hl or 10–25 g/hl are generally sufficient.
Divergan® RS may be repeatedly used in the recycling filter with low loss rates.
Divergan® adsorbs haze-forming polyphenols and thereby stabilizes beer and wine for long-lasting clarity. Divergan® is a cross-linked, insoluble polyvinylpyrrolidone, which is also known as PVPP. PVPP is unique in that it specifically adsorbs polyphenols responsible for turbidity, without concurrently altering the character of the beer.
