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.
Application fields
  • 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.
Application rate: 
A déterminer par des essais et des dégustations préalables. Les doses peuvent varier de 20 à 80 g/hl.
