Polyvinylpyrrolidone, additionally recognised as PVP, is a polymer of ethylene pyrrolidone. Due to its one-of-a-kind ranges of polymerization, it can be divided into soluble PVP and insoluble PVPP (polyvinylpyrrolidone). The relative molecular weight of soluble PVP is 8000~10000, which can be used as a precipitant to precipitate with the aid of reacting with polyphenols. By the use of this method, there are without problems residual PVP in the wine.
