Products Description of Polyvinylpyrrolidone CAS#9003-39-8

Polyvinylpyrrolidone, abbreviated as PVP, is a polymer of vinylpyrrolidone. Due to its different degree of polymerization, it is divided into soluble PVP and insoluble PVPP (polyvinylpolypyrrolidone). The relative molecular mass of soluble PVP is 8000-10000. It can be used as a precipitant and precipitate with polyphenols. With this method, it is easy for residual PVP to remain in the wine. Because PVP has an accumulation effect in the human body, the World Health Organization does not recommend the use of this substance.

In recent years, the use of soluble PVP has been rare. Insoluble PVPP has been used in the beer industry since the early 1960s. Its relative molecular mass is greater than 700000. It is a high molecular weight insoluble substance formed by further cross-linking and polymerization of PVP. It can be used as an adsorbent for polyphenols with good results.
