Claim Text:
1. A process for the production of a protein concentrate from an oilseed meal, comprising: i) mixing the meal with a first mixing solvent to form a mixture; ii) optionally adjusting the pH of the mixture to a pH of about 2.0 to about 10.0; iii) separating fiber from the mixture to form a protein slurry substantially free of fiber and a fiber fraction substantially free of protein, wherein the protein slurry comprises: iv) optionally repeating steps i)-iii) by mixing the protein slurry with additional meal; v) optionally mixing the fiber fraction with a second mixing solvent and repeating steps ii) and iii); vi) mixing the protein slurry with an alcohol containing extraction solvent to form an extract and a washed insoluble protein fraction, said washed insoluble fraction comprising the insoluble and soluble protein from the slurry, the soluble protein being denatured or rendered insoluble by contact with the alcohol; vii) separating the extract from the washed insoluble protein fraction; viii) optionally repeating steps vi) and vii) at least once; and ix) drying the washed insoluble protein fraction to form a protein concentrate comprising substantially all of the protein from the protein slurry.
