Polyethylene pyrrolidone referred to as PVP, vinyl pyrrolidone polymerization, because of its polymerization degree is different, and divided into soluble PVP and insoluble PVPP. The relative molecular weight of soluble PVP is 8000 ~ 10000, which can be used as a precipitator and can be precipitated by the action of polyphenols. By using this method, the wine is easy to have residual PVP. The World Health Organization does not recommend the use of PVP because of its cumulative effect in the human body. In recent years, the adoption of soluble PVP has been rare. Insoluble PVPP series began to be used in the beer industry in the early 1960s, with a mass of more than 700,000 pairs. It is a polymeric insoluble substance formed by further cross-linking polymerization of PVP, and can be used as the adsorbent of polyphenols, with good effect.
Widely used as thickening agent, emulsifier, lubricant and clarifying agent, but also as disinfection and sterilization agent PVP- complex as amine stabilizer and clarifying agent, can be used for the clarification of health wine, according to the production needs of appropriate use. Medical, aquaculture, animal husbandry disinfectant. Used for skin and mucous membrane disinfection. PolyFilterTM molecules have amide bonds and adsorb hydroxyl groups on polyphenol molecules to form hydrogen bonds. Therefore, PolyFilterTM can be used as stabilizers for e-wine, fruit wine, and beverage wine, extending its shelf life, and improving its transparency, color and taste. The product has secondary and renewable two specifications, disposable products suitable for small and medium-sized enterprises; Renewable products need to purchase special filtration equipment, but can be recycled, suitable for recycling large breweries. In daily cosmetics, PVP and copolymer of good dispersion and film forming, can be used as stereotyping liquid, spray hair gel and mousse stereotyping agent, hair protection agent of the sunshade, shampoo foam stabilizer, wave stereotyping agent and hair dye dispersant and pro mixture. Add PVP to snowflake, sunscreen and hair remover to enhance wetting and lubrication. Using PVP excellent surface activity, film formation and no irritation to the skin, no allergic reaction and other characteristics, has a broad prospect in hair care products, skin care products, and other aspects of the application of phenol and acid absorption from water extract to purify plant enzymes. Used as chromatographic adsorbent to separate aromatic acids aldehyme and phenolme. Used for wine and wine clarification.
