PVPP Granulée

PVPP Granulée

Polyvinyl polypyrrolidone for the prevention and rectification of oxidation

CHARACTERISTICS

Polyvinylpolypyrrolidone (PVPP – E1202) results from the polymerisation of vinylpyrrolidone. PVPP is made up of macromolecules arranged in a network and acts by adsorption.
Its granulated form makes it less powdery and easier to use.

APPLICATIONS

PVPP GRANULÉE improves the stability of wines by eliminating the oxidised and oxidizable phenolic compounds that affect the colour, clarity and organoleptic characteristics of wines.
• Polyphenols in wine often form soluble complexes with proteins: a decrease in protein content in wines is often observed after treatment with PVPP GRANULÉE.
• Its selectivity and affinity make it complementary to treatment with casein and bentonite, although it cannot be replaced by these two products.
