Abstract
A process in which treatment conditions in the extraction steps of the corn protein, zein, are stabilized and by which decolorized and purified zein can be provided in a stable manner through continuous treatment steps, while simultaneously providing techniques for the concentration and recovery of corn pigment components. Corn gluten meal is treated with a hydrocarbon solvent having 5 to 9 carbon atoms. Zein and pigment components are extracted from the treated corn gluten meal with a solvent, such as about 91 to 96% by volume ethanol, and zein and the pigment components are separated from the resulting extract solution. Oil and fat components and pigment components may be extracted from corn gluten meal prior to the zein extraction steps.
