Abstract

This disclosure describes methods for forming cell-based-meat products that mimic cuts of slaughtered meat. Generally, the disclosed method comprises forming a cell mass into primary structures, including fibers and/or sheets. A toughening agent is applied to the exterior surfaces of the primary structures, and the primary structures are arranged to mimic structures in a target slaughtered meat. The toughening agent creates a textural contrast that, during consumption, is like the textural contrast experienced when biting through bundles of meat fibers in slaughtered meat.

Claims (39)

1. A method for forming a cell-based-meat product comprising:

forming primary structures by filling, with a cell mass comprising cells grown in a reactor, containers having shapes of the primary structures;

applying a toughening agent to at least a portion of an exterior surface of the primary structures; and

arranging the primary structures comprising at least partially toughened exterior surfaces to mimic structures in a target slaughtered meat.

2. The method of claim 1 , wherein the cell mass comprises cells of a type from at least one of myocytes, adipocytes, or fibroblasts.

3. The method of claim 1 , further comprising organizing proto-fibers in the cell mass prior to or during forming the cell mass into the primary structures.

4. The method of claim 1 , wherein the primary structures are in the shape of at least one of a primary fiber or a primary sheet.

5. The method of claim 3 , wherein the proto-fibers in the cell mass are combed with tines to organize the proto-fibers.

6. The method of claim 3 , wherein the containers filled with the cell mass are bent to organize the proto-fibers.

7. The method of claim 1 , wherein applying the toughening agent further comprises:

applying the toughening agent to an interior surface of the containers;

filling the containers with the cell mass; and

applying the toughening agent to an exposed surface of the cell mass.

8. The method of claim 1 , further comprising:

removing the primary structures from the containers before spraying the toughening agent on exterior surfaces of the primary structures.

9. The method of claim 1 , further comprising:

removing the primary structures from the containers before immersing the primary structures in a bath comprising the toughening agent.

10. The method of claim 1 , wherein the toughening agent comprises at least one of gelatin, gelatin substitutes, carb-based texturizers, food-based tougheners, collagen, or fibroblasts.

11. A method for forming a cell-based-meat product comprising:

forming a cell mass into primary fibers, wherein the cell mass comprises cells grown in a reactor;

applying a toughening agent to exterior surfaces of the primary fibers; and

weaving the primary fibers comprising the toughened exterior surfaces to form a secondary fiber comprising interwoven primary fibers.

12. The method of claim 11 , further comprising weaving the secondary fiber with additional secondary fibers to form a tertiary fiber comprising interwoven secondary fibers.

13. The method of claim 11 , wherein applying the toughening agent comprises spraying the toughening agent onto the exterior surfaces of the primary fibers.

14. The method of claim 11 , further comprising applying a second layer of the toughening agent that at least partially coats the secondary fiber.

15. The method of claim 11 , wherein weaving the primary fibers comprises:

feeding the primary fibers through a guide ring;

attaching the primary fibers to a fiber braiding machine; and

twisting and extending the primary fibers through the guide ring by utilizing the fiber braiding machine.

16. The method of claim 4 , wherein arranging the primary structures comprises positioning at least one primary fiber at an angle relative to at least one primary sheet.

17. The method of claim 1 , wherein the primary structures are arranged to mimic a muscular architecture of a target cut of meat.

18. The method of claim 4 , wherein arranging the primary structures comprises positioning a plurality of primary fibers such that at least a portion of lengths of the plurality of primary fibers are parallel.

19. The method of claim 4 , wherein arranging the primary structures comprises:

arranging a primary sheet perpendicular to an interior surface of a mold, wherein the primary sheet mimics fascia connecting a tenderloin and a breast muscle; and arranging primary fibers perpendicular to the primary sheet on each side of the primary sheet, wherein:

a first set of primary fibers on a first side of the primary sheet mimic a shape of the tenderloin; and

a second set of primary fibers on a second side of the primary sheet mimic a shape of a breast muscle.

20. The method of claim 4 , wherein arranging the primary structures to mimic structures in the target slaughtered meat comprises:

arranging, in a mold, primary sheets of a first cell type mimicking layers of meat; and

layering, between the primary sheets of the first cell type, primary sheets of a second cell type mimicking layers of fat.
