Polyclar™ Plus 730
chemistry: PVP polymers and VP derivatives
SDS Link >Polyclar™ Plus 730 single-use, balanced beer stabilizer is a composite of Polyclar polyvinyl polypyrrolidone (PVPP) and a specially developed grade of silica xerogel. It benefits from the synergism between these two components by extending beer shelf life and filtration. A dual-action stabilizer, it offers highly effective reduction of both haze-forming polyphenols and haze-forming proteins.
The use of silica xerogel is the most common method of reducing haze-forming proteins. The gel adsorbs the proline-rich, haze-forming protein onto its surface. Hydrogen bonding between the silanol groups on the surface of the silica and the carbonyl groups of the proline creates a strong complex, allowing the filter’s insoluble silica to easily remove the haze-forming proteins.
The inclusion of PVPP in the admixture of Polyclar Plus 730 single-use, balanced beer stabilizer provides efficient and highly selective removal of haze-producing polyphenols, thus preventing the formation of insoluble protein-polyphenol complexes responsible for chill and permanent haze.
