SUCRE DE RAISIN
COEI-1-SUCRAI Grape sugar (rectified concentrated grape musts)
- Objective, origin and scope of application
Grape sugar is obtained exclusively from grape musts. The addition of grape sugar to wine is subject to regulation.
The label, or, when this is absent, the documentation accompanying the containers of grape sugar, must cite the sugar percentage.

RESINES ECHANGEUSES DE CATIONS
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 conta

- 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.
MATIERES PROTEIQUES D’ORIGINE VEGETALE
COEI-1-PROVEG Protein plant origin from peas and potatoes
- Object, origin and field of application
The plant protein matter described in this monograph is extracted from 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. It is intended for human consumption.
