Methods of manufacturing products from material comprising oilcake, compositions produced from materials comprising processed oilcake, and systems for processing oilcake

1. A method comprising:

de-solubilizing protein in a first material comprising oilcake to produce a processed material comprising an insoluble protein fraction by extruding the first material in a pressure range of 10 bar to 80 bar;

hydrolyzing the processed material to produce a mixture comprising the insoluble protein fraction and a hydrolyzed fraction;

separating the insoluble protein fraction from the hydrolyzed fraction; and

processing the insoluble protein fraction into a product by extruding the insoluble protein fraction in a pressure range of 10 bar to 80 bar.

2. The method of claim 1 , wherein the first material further comprises at least one of a distiller grain, pulp, a pomace, a legume, a mushroom, or microbial protein, or any combination thereof.

3. The method of claim 1 , wherein the oilcake comprises at least one of a sunflower oilcake, a soybean oilcake, a cottonseed oilcake, a rapeseed oilcake, a canola oilcake, a copra oilcake, a palm kernel oilcake, a peanut oilcake, an olive oilcake, or a locust bean cake, or any combination thereof.

4. The method of claim 1 , wherein the oilcake comprises sunflower oilcake.

5. The method of claim 1 , wherein the product is a meat-analog.

6. The method of claim 1 , further comprising at least one of toasting the first material, drying the first material, adding salt to the first material, or adjusting the pH of the first material, or any combination thereof.

7. The method of claim 1 , further comprising extruding the first material or the insoluble protein fraction in a temperature range of 70 degrees Celsius to 200 degrees Celsius.

8. The method of claim 7 , wherein extruding the insoluble protein fraction comprises adjusting a moisture content of the insoluble protein fraction to be in a range of 40 percent to 80 percent of moisture based on the total weight of the insoluble protein fraction.

9. The method of claim 1 , wherein de-solubilizing protein in the first material and processing the insoluble protein fraction are performed in the same extruder.

10. The method of claim 1 , wherein de-solubilizing protein in the first material and processing the insoluble protein fraction are performed in different extruders.

11. The method of claim 1 , further comprising contacting the protein fraction with a cooled section of a barrel of an extruder during processing.

12. The method of claim 1 , wherein hydrolyzing comprises at least one of adding enzyme and adding an acid.

13. The method of claim 1 , wherein hydrolyzing comprises adding enzyme.

14. The method of claim 13 , wherein the enzyme comprises at least one of cellulase, alpha-galactosidase, xylanase, glucanase, amylase, liginase, transglutaminase, endoglucanase, or hemicellulase, or any combination thereof.

15. The method of claim 1 , wherein separating comprises at least one of centrifuging the mixture, decanting the mixture, or precipitating the protein fraction from the mixture, or any combination thereof.

16. The method of claim 1 , wherein processing the insoluble protein fraction comprising fractionating.

17. The method of claim 1 , further comprising mixing the product with at least one of a starch, a flour, a mineral, a vitamin, water, oil, protein, or a food agent, or any combination thereof.

18. The method of claim 1 , further comprising adding water to the mixture at a ratio in a range of 1 part of mixture: 6 parts of water to 1 part of mixture: 2 parts of water.
