Abstract
Procédé pour décaféiner le grain de café vert, dans lequel le grain est soumis à une extraction avec un liquide aqueux et l'extrait obtenu est traité avec une résine de matière polymère synthétique qui adsorbe préférentiellement la caféine. La résine employée est du type obtenu par polymérisation ou copolymérisation de monomères à systèmes cycliques aromatiques et groupes acides, et pour laquelle, de plus, le rapport de la capacité totale d'adsorption pour la caféine à la capacité totale d'échange d'ions est supérieure à 1 environ et inférieur à 25 environ, et de préférence compris entre 5 et 15. Grâce au choix d'une telle résine, il ne se produit pas d'altérations notables de la composition ionique de l'extrait des grains verts, l'emploi de solvants organiques étant cependant entièrement évité, c'est-à-dire y compris dans la phase de régénération de la résine.
