Method and system for removing anti-nutritionals from a feed stock

1. A method for anti-nutritional removal comprising:

generating a feed stock from a plant-based protein source of fava beans, the plant-based protein source having anti-nutritionals including vicine and covicine disposed therein;

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;

providing the feed stock mass to a desolventizer and generating a desolventized feed stock mass therefrom;

drying the desolventized feed stock mass to generate a clean feed stock with at least a portion of the anti-nutritionals removed therefrom; and

processing the clean feed stock for generating a protein source output having at least a portion of the anti-nutritionals removed therefrom including having at least a portion of the vicine and covicine removed therefrom.

2. The method of claim 1 , wherein generating the feed stock includes at least one of: flaking and milling the plant-based protein source.

3. The method of claim 1 , wherein the plant-based protein source output is in the form of at least one of: flakes, meal and powder.

4. The method of claim 1 the method further comprising:

providing the ethanol matrix to an evaporator for recovering the ethanol therefrom, wherein the evaporator is separate from the desolventizer.

5. The method of claim 4 wherein the ethanol is recovered via evaporation and refed with the ethanol wash.

6. The method of claim 1 , wherein the anti-nutritionals include vicine and covicine.

7. The method of claim 1 , wherein the generating of the ethanol slurry is performed using at least one of: an immersion blender and a counter-current extractor.

8. The method of claim 1 , wherein processing the clean feed stock for generating a protein source output includes:

generating an initial alkalized slurry by combining the clean feed stock, water and a base using a first mixer;

transporting the initial alkalized slurry from the first mixer to a first separator using a first low shear pump,

generating a solubilized protein rich stream by separating the initial alkalized slurry from a starch precipitate in the first separator;

generating a de-oiled solubilized protein rich stream by separating out oil from within the solubilized protein rich stream;

generating a protein precipitate including an acid curd by mixing the de-oiled solubilized protein rich stream with an acid using a second mixer and separating the acid curd from the protein precipitate;

washing the first protein curd using a wash station to generate a second protein curd;

generating a neutral hydrolyzed protein slurry by mixing the second protein curd with a base and water using a third mixer;

generating a homogenized protein slurry from the protein slurry;

generating a pasteurized protein slurry from the homogenized protein slurry by pasteurizing the homogenized protein slurry;

cooling the pasteurized protein slurry to generate a cooled protein slurry therefrom; and

recovering the protein concentrate from the cooled protein as the protein source output.

9. A method for removing of vicine and covicine from fava beans, the method comprising:

processing the fava beans to generate a feed stock, wherein the fava beans have vicine and covicine disposed therein;

generating a solvent slurry by combining the feed stock with a solvent wash containing a first volume of solvent;

processing the solvent slurry through an extractor to generate a solvent matrix and a feed stock mass;

providing the feed stock mass to a desolventizer and generating a desolventized feed stock mass therefrom; and

drying the desolventized feed stock mass to generate a clean feed stock with at least a portion of the vicine and covicine removed therefrom.

10. The method of claim 9 further comprising:

processing the clean feed stock for generating a protein source output in the form of at least one of: flakes, meal and powder.

11. The method of claim 10 , wherein the processing the clean feed stock includes:

generating an initial alkalized slurry by combining the clean feed stock, water and a base using a first mixer;

transporting the initial alkalized slurry from the first mixer to a first separator using a first low shear pump,

generating a solubilized protein rich stream by separating the initial alkalized slurry from a starch precipitate in the first separator;

generating a de-oiled solubilized protein rich stream by separating out oil from within the solubilized protein rich stream;

generating a protein precipitate including an acid curd by mixing the de-oiled solubilized protein rich stream with an acid using a second mixer and separating the acid curd from the protein precipitate;

washing the first protein curd using a wash station to generate a second protein curd;

generating a neutral hydrolyzed protein slurry by mixing the second protein curd with a base and water using a third mixer;

generating a homogenized protein slurry from the protein slurry;

generating a pasteurized protein slurry from the homogenized protein slurry by pasteurizing the homogenized protein slurry;

cooling the pasteurized protein slurry to generate a cooled protein slurry therefrom; and

recovering the protein concentrate from the cooled protein as the protein source output.

12. The method of claim 9 further comprising:

providing the solvent matrix to an evaporator for recovering the solvent therefrom, wherein the evaporator is separate from the desolventizer.

13. The method of claim 9 , wherein the solvent includes at least one of: ethanol, hexane, and isopropyl alcohol.
