EXTRACTION OF ZEIN PROTEIN FROM GLUTEN MEAL

摘要

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 cru de zein extract with an adsorbent that adsorbs at least one of color, odor, oil and fatty acid; and to yield a purified zein extract.
