Method of extracting proteins utilizable in foodstuff from a protein-containing substance
First Claim
1. A method for the production of proteins suitable for foodstuff from a protein-containing, plant based substance, comprising the steps of:
- homogenizing a mixture of the protein-containing substance and an alkaline alcohol solution having a pH greater than 11.5 to form a second solution, said homogenizing conducted at room temperature and by high pressure disintegration, whereby the proteins contained in the substance are dissolved into the second solution;
during the step of homogenizing, extracting thermal energy from the second solution introduced by the homogenization so that the temperature of the second solution is maintained at room temperature;
separating insoluble components from the second solution;
neutralizing the second solution;
desalinating the second solution; and
concentrating the proteins contained in the second solution by a drying process.

Abstract
In the method described, a protein-containing substance is first taken up in an alkaline solvent to give a solution. Insoluble constituents of the substance are separated off, the solution is neutralized and desalinated, and then the proteins contained in the solution are concentrated. The solubilization or disintegration of the protein-containing substance is carried out at room temperature using homogenization equipment. The heat dissipated into the protein-containing substance during homogenization is simultaneously removed. The pH of the alkaline solvent during the decomposition is over 11.5 and/or decomposition is carried out in the presence of a detergent, in particular sodium dodecylsulfate (SDS).
