Cation exchange resins
COEI-1-RESECA Cation exchange resins
- Objective, origin and scope of application
Ion exchange is the reversible exchange of ions between a liquid and a solid, during the course of which the solid does not undergo any substantial changes. When this technique is applied to wine, the solid is an insoluble, permeable synthetic resin capable of exchanging ions with the wine with which it is in contact.

Polyvinylimidazole/Polyvinylpyrrolidone
COEI-1-PVIPVP Adsorbent copolymers of polyvinylimidazole/ Polyvinylpyrrolidone (PVI/PVP)
N° CAS: 87865-40-5
- Object, origin and scope of application
Adsorbent copolymers of PVI/PVP are insoluble and slightly-hygroscopic powders. They are manufactured by "popcorn" polymerization of N-vinylimidazole (CAS no. 1072-63-5,) and N-vinyl-2-pyrrolidone (CAS no.
Protein plant origin
COEI-1-PROVEG Protein plant origin from wheat, peas and potatoes
- Object, origin and field of application
The plant protein matter described in this monograph is extracted from wheat (Triticum vulgaris), peas (Pisum sativum), or potatoes (Solanum tuberosum). It is mainly made up of proteins and may contain, as minority constituents, carbohydrates (fibres, starch, sugars), fats and minerals.

Potassium caseinate
COEI-1-POTCAS Potassium caseinate
- Objective, origin and scope of application
Potassium caseinate is obtained from fresh or pasteurized skimmed milk by acid coagulation of the casein (see monograph), neutralization using potassium hydroxide and drying with a spray dryer. It is used for the fining of wines.
