Polyvinylpyrrolidone, additionally acknowledged as PVP, is a polymer of ethylene pyrrolidone. Due to its unique 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 by way of reacting with polyphenols. By the usage of this method, there are effortlessly residual PVP in the wine.
