Food analogs and methods for making food analogs
View Patent ↗The invention provides food analogs and methods of making the food analogs. In general, the methods comprise comminuting one or more meats to produce a meat slurry, admixing one or more flours to produce a powder blend, admixing the meat slurry and the powder blend to produce a dough, and extruding the dough at a shear mechanical energy ranging from about 50 kJ/kg to about 500 kJ/kg and at a temperature ranging from about 60° C. to about 120° C. to produce a food analog. Colorant can be added before, during, or after the admixing or extrusion processes to provide a more natural appearance to the food analog. The food analog can be a meat analog having the appearance of a meat or a non-meat food analog such as a fruit or vegetable.
1. A method for making a food analog, the method comprising:
comminuting one or more meats to produce a meat slurry;
admixing one or more flours to produce a powder blend;
admixing the meat slurry and the powder blend to produce a dough; and
injecting live yeast into the dough while extruding the dough at a shear mechanical energy ranging from about 50 kJ/kg to about 500 kJ/kg and at a temperature ranging from about 60° C. to about 120° C. to produce the food analog, and the live yeast is 0.2 wt. % to 0.4 wt. % of the food analog.
2. The method of claim 1 further comprising cutting the food analog into pieces to produce food analog pieces.
3. The method of claim 1 further comprising adding one or more colorants to the meat slurry, and the food analog is a colored food analog.
4. The method of claim 1 further comprising adding one or more colorants to the powder blend, and the food analog is a colored food analog.
5. The method of claim 1 further comprising adding one or more colorants to the admixed meat slurry and the powder blend, and the food analog is a colored food analog.
6. The method of claim 5 wherein the one or more colorants are added to the dough while extruding the dough.
7. The method of claim 1 further comprising adding one or more colorants to a component selected from the group consisting of the meat slurry, the powder blend, the admixed meat slurry, and a combination thereof, and the food analog is a colored food analog.
8. The method of claim 7 wherein the food analog is a meat analog, and at least one of the one or more colorants is selected from the group consisting of: (1) azorubine to produce a colored meat analog having a dark red appearance; (2) paprika oleoresin to produce a colored meat analog having a light red appearance; (3) a combination of titanium dioxide, allura red, and xanthane to produce a colored meat analog having a pink appearance; (4) a combination of titanium dioxide and xanthane to produce a colored meat analog having, a white appearance; (5) a combination of a poultry fat, plasma powder, xylose, and sodium monoglutamate to produce a colored meat analog having a dark brown appearance; and (6) a combination of dried egg yolk, caramel color, and starch to produce a colored meat analog having a light brown appearance.
9. The method of claim 2 wherein:
the food analog pieces have the shape and the color of pieces of a fruit or vegetable selected from the group consisting of potatoes, zucchini, apples, carrots, eggplant, and peppers,
the method further comprises adding one or more colorants to a component selected from the group consisting of the meat slurry, the powder blend, the admixed meat slurry, and combinations thereof, and the food analog is a colored food analog, and
at least one of the one or more colorants is selected from the group consisting of: (1) a combination of canthaxanthin and xanthene to produce a food analog having an orange appearance; (2) a combination of dried egg yolk and tartrazine to produce a food analog having a yellow appearance; (3) a combination of titanium dioxide and riboflavine to produce a food analog having a light yellow appearance; (4) a combination of sodium copper chlorophyllin and titanium dioxide to produce a food analog having a pale green appearance; and (5) a combination of tartrazine, indigo carmine, and nitrited salt to produce a food analog having a green appearance.
10. The method of claim 7 wherein the colorant is titanium dioxide, and the food analog pieces have the color and shape of pieces of fish.
11. The method of claim 1 further comprising applying one or more colorants to the food analog after extrusion to produce a colorant coated food analog.
12. The method of claim 11 further comprising cutting the colorant coated food analog to produce cut colorant coated food analog pieces.
13. The method of claim 12 further comprising drying the cut colorant coated food analog pieces.
14. The method of claim 11 further comprising drying the colorant coated food analog to produce a dried colorant coated food analog.
15. The method of claim 14 further comprising cutting the dried colorant coated food analog to produce colorant coated food analog pieces.
16. The method of claim 1 wherein the dough comprises from about 30% to 70% by weight of the meat slurry and from about 30% to about 70% by weight of the powder blend.
17. The method of claim 1 wherein the food analog has a moisture content of 12 wt. % to 19 wt. % and a water activity of 0.6 to 0.8.
18. The method of claim 1 wherein the shear mechanical energy of the extruding is from 275 kJ/kg to about 500 kJ/kg.
