In the beverage industry:

PVPP can be used as stabilizer and clarifier for beers, wines and fruit juices in beverage industry.

Alcoholic drinks with low degree, which are brewed from floral material such as wheat, corn and hops, are abundant in proteins and polyphenols. Proteins can form complexes with polyphenols under certain condition. The complexes will precipitate to make beverage turbid and seriously affect color, flavor, foam and shelf-span of beverage. To improve the stability of beverage, the center of the method is to remove proteins and polyphenols off to prevent the complexes formation. There are PVPP absorption- filtration method, silica gel absorption- filtration method and protease decomposition method. Complexes formed from PVPP with polyphenols will be precipitated or absorbed and then be filtered out. The outstanding advantages of PVPP is shown as following: high selectivity of absorption to polyphenols, low dosage, short contact time with beer, no effect on foam and flavor, thorough removal from beer, can be used together with other materials, great improvement of beer stability.

 

PROPERTIES:

Polyvinylpolypyrrolidone is often called as crosslinked PVP, or insoluble PVP. It appears as white or light yellow, free flowing hygroscopic powder, odorless or with faint characteristic odor. It is insoluble in water, alkali, acid and common organic solvents.It has strong swellability and can complex with polyphenols, carboxylic acid andother compounds with low molecular weight.
