Polyclar™ 10

chemistry: PVP polymers and VP derivatives

Polyclar™ 10 single-use beer stabilizer is a highly effective, 100% polyvinyl polypyrrolidone (PVPP) beer stabilizer. It is optimized for single use on its own or in conjunction with other stabilizers, to offer a highly effective means of preventing non-biological haze in all types of beer.

Non-biological haze formation results primarily from hydrogen bonding between haze-producing proteins and the polyphenol constituents of beer. To achieve colloidal stability, it is necessary to reduce these protein-pholyphenol complexes or prevent them from forming. Polyclar 10 beer stabilizer complexes with specific polyphenols in beer via hydrogen bonding and is then removed during filtration. The bonding occurs between the carbonyl groups of Polyclar 10 beer stabilizer and the hydroxyl groups of polyphenols.
