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.
O zein é recuperado da refeição do gluten preparada por procedimentos moendo molhados lavando o gluten com água limpa para remover os componentes water-soluble; separando os componentes water-soluble e recuperar os componentes water-insoluble; extraindo os componentes insoluble da água com o solvente hydrous do ethanol para extrair o zein; recuperando o extrato cru do zein; tratando o extrato cru do zein com um adsorbent que adsorbs ao menos um da cor, do odor, do óleo e do ácido fatty; e para render um extrato purified do zein.
