Abstract

Meat substitute recipes with animal cells and exogenous heme-containing protein on plant-based meat dough matrices are disclosed. Methods of producing are also disclosed.

Claims (25)

1. A hybrid meat substitute product comprising:

a) at least 60% by weight plant-based meat dough;

b) at least 2.5% by weight cultured animal cells; and

c) at least 0.50% by weight exogenous heme-containing protein,

wherein the cultured animal cells and the exogenous heme-containing protein synergistically improve the meaty flavor of the hybrid meat substitute product.

2. The hybrid meat substitute product of claim 1 , comprising:

d) animal fat.

3. The hybrid meat substitute product of claim 1 , wherein the animal cells comprise, or are derived from, skeletal muscle cells, myoblasts, myogenic cells, fibroblasts, mesenchymal stem cells, endothelial cells, adipose progenitor cells, preadipocytes, or cardiomyocytes.

4. The hybrid meat substitute product of claim 1 , wherein the animal cells are not hepatocytes.

5. The hybrid meat substitute product of claim 1 , wherein the animal cells are myoblasts.

6. The hybrid meat substitute product of claim 1 , wherein the animal cells are fibroblasts.

7. The hybrid meat substitute product of claim 1 , wherein the animal cells are not in a meat structure.

8. The hybrid meat substitute product of claim 1 , comprising between 2.5-20% the animal cells by weight.

9. The hybrid meat substitute product of claim 1 , comprising between 2.5-6% the animal cells by weight.

10. The hybrid meat substitute product of claim 1 , comprising between 0.5-2% the exogenous heme-containing protein by weight.

11. The hybrid meat substitute product of claim 1 , comprising at least 0.75% the exogenous heme-containing protein by weight.

12. The hybrid meat substitute product of claim 1 , wherein the exogenous heme-containing protein is selected from the group consisting of a non-symbiotic hemoglobin, a Hell's gate globin I, a flavohemoprotein, a leghemoglobin, a heme-dependent peroxidase, a cytochrome c peroxidase, a mammalian myoglobin, an androglobin, a cytoglobin, a globin E, a globin X, a globin Y, a hemoglobin, a myoglobin, an erythrocruorin, a beta hemoglobin, an alpha hemoglobin, a protoglobin, a cyanoglobin, a cytoglobin, a histoglobin, a neuroglobins, a chlorocruorin, a truncated hemoglobin, a truncated 2/2 globin, a hemoglobin 3, a cytochrome, and a peroxidase.

13. The hybrid meat substitute product of claim 1 , wherein the exogenous heme-containing protein is a myoglobin.

14. The hybrid meat substitute product of claim 13 , wherein at least 50% of the myoglobin is oxymyoglobin.

15. The hybrid meat substitute product of claim 1 , wherein the heme-containing protein is bovine myoglobin, wherein the bovine myoglobin comprises an amino acid sequence having at least 80%, 85%, 90%, or 95% identity to SEQ ID NO: 1.

16. The hybrid meat substitute product of claim 2 , wherein the animal fat is from cultivated cells.

17. The hybrid meat substitute product of claim 2 , wherein the animal fat is from cultivated adipocytes.

18. The hybrid meat substitute product of claim 2 , comprising between 0.1-30% the animal fat by weight.

19. The hybrid meat substitute product of claim 2 , comprising between 10-20% total fat by weight.

20. The hybrid meat substitute product of claim 1 , wherein the exogenous heme-containing protein is provided as a cell-free ingredient.
