PVP itself does not cause cancer, and a good food safety, with particular form complex polyphenol compounds (such as tannins), mainly in food processing as beer, juice, wine and other food clarifying agent and stabilizer. PVP can with specific polyphenol compounds, such as tannins complex formation, in the fruit juice clarification effect and anti coagulation. As Buschke H is added in the fermentation tank 0. 01% ~ 0.02% soluble PVP, can effectively reduce the freezing point. In wine and vinegar, etc used in the production process of PVP can also have the same effect. Crosslinked PVP application in the beer and tea drinks is extensive, the polyphenols in beer can combined with proteins in beer, generate tannins macromolecular compounds, will seriously affect the flavor of beer, and shorten the shelf life. And cross-linked polyvinylpyrrolidone (PVPP) with the tannic acid in beer and anthocyanins complexation, making beer clarification, and improve the storage stability of beer, prolong shelf life. In tea drinks, using PVPP can reduce the content of tea polyphenol, appropriately and PVPP no residues in tea drinks, reusable, greatly reduce the cost.
