Zein is recovered from gluten meal prepared by wet milling procedures by washing the gluten with clean water to remove water-soluble components; separating the water-soluble components and recovering the water-insoluble components; extracting the water insoluble components with hydrous ethanol solvent to extract zein; recovering the crude zein extract; treating the crude zein extract with an adsorbent that adsorbs at least one of color, odor, oil and fatty acid; and to yield a purified zein extract.

Pour récupérer une zéine dans un plat contenant du gluten préparé au moyen de procédures de mouture humide, on lave le gluten avec de l'eau saine pour éliminer les constituants solubles dans l'eau; on sépare les constituants solubles dans l'eau et on les récupère; on extrait les constituants solubles dans l'eau avec un solvant à base d'éthanol hydraté pour extraire la zéine; on récupère l'extrait de zéine brute; on traite l'extrait de zéine brute avec un adsorbant qui adsorbe au moins une couleur, une odeur, une essence et un acide gras et on obtient un extrait de zéine purifiée.
