Vicine and covicine removal from a feed stock

A method for vicine and covicine removal comprising:

• generating a feed stock from a plant-based protein source having anti-nutritionals disposed therein, the anti-nutritionals including vicine and covicine;
• generating an ethanol slurry by combining the feed stock with an ethanol wash containing a first volume of ethanol;
• processing the ethanol slurry through an extractor to generate an ethanol matrix and a feed stock mass;
• generating a desolventized feed stock mass from the feed stock mass;
• and
• generating a clean feed stock from the desolventized feed stock mass, wherein generating the clean feed stock removes at least a portion of the vicine and covicine and a plurality of additional compounds from the clean feed stock, wherein the compounds include one or more of:
• non-protein amino acids, alkaloids, glycosides, isoflavones, tannins, oligosaccharides, phytic acid, saponins, polyphenols, protease inhibitors, alpha-amylase inhibitors, trypsin inhibitors, lectins ethers and esters.
