1. A method for removing oil content from a source material and extracting protein from the source material prior to generating a protein concentrate, the method comprising:
decorticating the source material, the source material having a protein and an oil content therein, the decorticating removing a cortex from the source material;
creating a flour from the source material having the cortex removed therefrom;
removing at least a portion of the oil content from the flour by generating a solvent mixture by mixing the flour with a first solvent including supercritical carbon dioxide;
extracting a de-oiled flour from the solvent mixture, including extracting at least a portion of the first solvent from the solvent mixture, the portion of the first solvent extracted from the solvent mixture including oil and sugars extracted from the flour;
drying the de-oiled flour using at least one dryer; and
extracting a protein concentrate from the de-oiled flour.
