| Description: | Polyvinylpyrrolidone is abbreviated as PVP, and is the polymer of vinylpyrrolidone. According to the different degree of polymerization, it is further classified into soluble PVP and insoluble PVPP (polyvinyl polypyrrolidone). Molecular weight of the soluble PVP is 8,000 to 10,000.The soluble PVP can be used as a precipitating agent which can be settle down through its action with polyphenols. Using this method, it is easily to have residual PVP in the alcohol. Due to the savings effect of PVP inside the human body, the World Health Organization doesn''t recommend to apply this substance. In recent years, the use of soluble PVP has been rare. Insoluble PVPP system had began to be used in the beer industry since the early 1960s. It has a relative molecule weight greater than the relative mass greater than 700,000. It is a insoluble polymer derived from the further cross-linking and polymerization of PVP and can be used as an adsorbent of polyphenols with a good efficacy. | |
