The present invention is an improved method for producing an aqueous solution of zein. In accordance with this method, the water to be used has its pH adjusted to an intermediate pH between about 8.0 and about 10.5. Following this adjustment, a quantity of powdered zein is added to the water in an amount between about 5 and about 20 percent by weight of the water and zein mixture. This mixture is agitated until the zein is well dispersed in the water. Also, during the zein addition, the pH is readjusted to the 8.0 to 10.5 range. After the zein is well dispersed, the pH of the mixture is adjusted to a final pH between about 11.5 and about 12.1. Agitation of the mixture is continuted until substantially all of the zein is solvated in the water.
