Oil seed proteins evidencing improved functionality
First Claim
1. A process for treating extracted vegetable protein which comprises:
- 1. adjusting the pH of an aqueous solution of extracted vegetable protein having from about 70% to about 95% protein wherein at least a major proportion of the protein is insoluble at its isoelectric point, said protein being soluble in alkaline solution, to a pH within the range of from about 7.5 to about 12, the total solids of said solution ranging from about 5% to about 10% by weight, and the total dissolved protein content ranging from about 3.5% to about 9.5% by weight when determined at said pH;

Abstract
A process for improving the viscosity of vegetable protein-containing solutions which comprises:
1. adjusting the pH of an aqueous solution containing from about 3.5% to about 9.5% vegetable protein such as an oil seed protein wherein at least a major proportion of the protein is insoluble at its isoelectric point to a pH within the range of from about 7.5 to about 12;
2. heating the alkaline solution of step (1) to an elevated temperature at a rate sufficient to produce an increase in viscosity and insufficient to provide a reduction in solubility; and
3. cooling said heated solution to a temperature sufficient to retard further substantial change in the protein.
