Polyvinylpolypyrrolidone (PVPP) is also known as what?

Polyvinylpolypyrrolidone (PVPP) is commonly known as Povidone. This compound is a water-soluble polymer that is often used in the food and beverage industry as a fining agent. It works by adsorbing polyphenolic compounds, which helps to clarify beverages such as wine and beer. Its effectiveness in improving clarity and stability is well-documented, making it a preferred choice in various applications.

The other substances listed do not share the same chemical structure or function as PVPP. Glycerol is a simple polyol compound used primarily as a sweetener or humectant, acomycin is an antibiotic, and succinic acid is a dicarboxylic acid involved in metabolic processes. Thus, among the choices provided, Povidone is the accurate designation for PVPP.
