Abstract

A meat analogue may include a macrostructure of connected sheared fibers oriented parallel to one another and gaps positioned between the sheared fibers. The macrostructure may not include meat and may include a vegetable protein. An extrusion system may include an extruder and a die. The extrusion system may produce a meat analogue. A meat analogue may include a plant protein. The extruder may be connectable to the die. The extrusion system may be configured to direct a material including a vegetable protein from the extruder to the die and through a fluid path extending through the die. The die may be configured to inject a fat or a fat analogue into the material such that the fat or the fat analogue is embedded but visually distinct from the material including the vegetable protein when the fat or the fat analogue and the material exit the die.

First claim

What is claimed is:

1. A method of extruding a meat analogue comprising a vegetable protein, the method comprising:
applying a pressure to the meat analogue with an extruder;
passing the meat analogue through a short die in a direction of flow, wherein the short die is part of and/or connected to the extruder, and the short die is a die where the length of the die, defined as the length a material travels through the die when the die is in use, is less than the width of the die, defined as the longest dimension of a planar section of the die outlet through which the material passes when exiting the die;
creating a texture of sheared fibers in the meat analogue substantially perpendicular to the direction of flow of the meat analogue as the meat analogue is passed through the short die;
injecting a fat or a fat analogue into the meat analogue as the meat analogue is passed through the short die such that the fat or the fat analogue is embedded in but visually distinct from the meat analogue, wherein the fat analogue comprises at least one of a hydrocolloid or a gellified emulsion of fat and protein; and
creating a periodical increase or decrease in a flow rate within the meat analogue when the meat analogue is passed through the short die.

2. The method according to claim 1 , the method further comprising adding one or more insoluble particles of vegetable origin.

3. The method according to claim 1 , the method further comprising adding a pea hull to the meat analogue.

4. The method according to claim 1 , the method further comprising maintaining the short die at a temperature below about the boiling temperature of water according to a temperature and a pressure in the meat analogue at the exit of the short die.

5. The method according to claim 1 , the method further comprising cutting the meat analogue to resemble a marbled beef steak.

6. The method according to claim 1 , wherein the meat analogue contains a pea protein or faba bean protein.

7. The method according to claim 1 , the method further comprising cooling the meat analogue from an initial temperature while passing the meat analogue through the short die.

8. The method according to claim 1 , the method further comprising maintaining the short die at a temperature between about 70° C. and about 90° C.

9. The method according to claim 1 , wherein the short die is selected from the group consisting of a coat hanger die, a fish-tail die, and a combination thereof.

10. The method according to claim 1 , wherein the creating the texture of sheared fibers in the meat analogue comprises creating the texture of sheared fibers in the meat analogue within about ±15 degrees to a direction perpendicular to the direction of flow of the meat analogue as the meat analogue is passed through the short die.

11. The method according to claim 1 , wherein the meat analogue comprises an emulsion product that resembles one or more pieces of natural meat in appearance, texture, and physical structure.

12. The method according to claim 1 , wherein the meat analogue does not include natural meat.
