Abstract
Processes for treating a zein containing material to decrease inherent color and smell as well as for obtaining zein component therefrom, which is decreased in color tone and smell. The removal of color and smell is carried out by contacting the material with an aqueous acetone solution having acetone concentration which causes almost no dissolution of the zein component. An extraction of zein component from the raw material is carried out in a conventional manner, for instance, with use of an aqueous ethyl alcohol.
