Abstract

A package for packaging a meat product. The package comprises a multilayer film with a food contact sealant layer and a food additive in an amount sufficient to capture oxygen bound to myoglobin on the surface of the meat product. The meat product may have a conversion rate of oxymyoglobin to deoxymyoglobin with less than 5% metmyoglobin remaining on the surface of the meat product within a time period of 36 hours or less. The present invention may also be used in a low oxygen environment package, such as vacuum skin packaging.

Claims (41)

1 . A package for packaging a meat product, comprising:

a. a multilayer film comprising a food contact sealant layer comprising at least one member selected from the group consisting of polyolefins, EVA, ionomers, PET, and polyethylene; and

b. a food additive in an amount sufficient to capture oxygen bound to myoglobin on the surface of the meat product,

wherein the oxymyoglobin in the meat product converts to deoxymyoglobin within the package, the total myoglobin on the surface of the meat product contains less than 5% metmyoglobin within a time period of 36 hours or less from the time of packaging.

2 . The package of claim 1 , wherein the food additive comprises at least one member selected from the group consisting of acerola extract, rosemary extract, dry vinegar, green tea extracts, jasmine tea extract, grape seed extract, olive pulp, bamboo leaf, tocopherol succinate, d-alpha-tocopherol, ascorbic acid, and acetic acid.

3 . The package of claim 1 , wherein the multilayer film is a high oxygen barrier film.

4 . The package of any one of claim 1 , wherein the package is a vacuum skin package.

5 . The package of any one of claim 1 , wherein the food additive is applied to the multilayer film as a coating.

6 . The package of claim 5 , wherein the food additive is applied to the food contact layer of the multilayer film as a dust coating.

7 . The package of claim 5 , wherein the food additive is applied to the food contact layer of the multilayer film as a wet coating.

8 . The package of claim 1 , wherein the food additive is incorporated into the food contact layer of the multilayer film.

9 . The package of claim 1 , wherein the food additive is water soluble.

10 . The package of claim 1 , wherein the meat product is fresh red meat.

11 . The method of any one of claim 1 , wherein the time period is 24 hours or less.

12 . The method of any one of claim 1 , wherein the multilayer film is an oriented multilayer film.

13 . The method of any one of claim 5 , wherein the coating contains between 0.001 grams/square inches to 0.5 grams/square inches solids.

14 . A method for the conversion of metmyoglobin to deoxymyoglobin on the surface of a meat product, comprising:

a. providing a multilayer film comprising a food contact sealant layer comprising at least one member selected from the group consisting of polyolefins, EVA, ionomers, PET, and polyethylene;

b. adding a food additive in an amount sufficient to capture oxygen bound to myoglobin on the surface of the meat product to the multilayer film;

c. forming a barrier package from the multilayer film;

d. placing a meat product inside the barrier package, wherein the meat product contacts the food additive; and

e. sealing the barrier package closed with the meat product inside the barrier package,

wherein the oxymyoglobin in the meat product converts to deoxymyoglobin within the package, the total myoglobin on the surface of the meat product contains less than 5% metmyoglobin within a time period of 36 hours or less from the time of packaging.

15 . The method of claim 14 , wherein the food additive is applied to the multilayer film as a dust coating or a wet coating.

16 . (canceled)

17 . (canceled)

18 . The method of claim 14 , wherein the food additive is incorporated into the food contact layer of the multilayer film.

19 . The method of any one of claim 14 , wherein the food additive is water soluble.

20 . (canceled)

21 . The method of any one of claim 14 , wherein the time period is 24 hours or less.

22 . The method of any one of claim 14 , wherein the barrier package comprises at least one member selected from the group consisting of a flexible thermoformed oxygen barrier package with a low oxygen atmosphere, a rigid thermoformed oxygen barrier package with a low oxygen modified atmosphere, a non-shrink flexible pouch with a low oxygen atmosphere, an evacuated shrinkable barrier bag, an evacuated non-shrink flexible pouch, an evacuated oxygen permeable film package with a low oxygen gas flushed rigid container, an oriented bag, a non-oriented flexible pouch, and a barrier bag.

23 . A method for the conversion of oxymyoglobin to deoxymyoglobin on the surface of a meat product, comprising:

a. providing a multilayer film comprising a food contact sealant layer comprising at least one member selected from the group consisting of polyolefins, EVA, ionomers, PET, and polyethylene;

b. adding a food additive in an amount sufficient to capture oxygen bound to myoglobin on the surface of the meat product to the surface of the meat product;

c. forming a barrier package from the multilayer film; and

d. placing a meat product inside the barrier package, wherein the food additive has been added to the surface of the meat product before placing the meat product inside the barrier package; and

e. sealing the barrier package closed with the meat product inside the barrier package,

wherein the oxymyoglobin in the meat product converts to deoxymyoglobin within the package, the total myoglobin on the surface of the meat product contains less than 5% metmyoglobin within a time period of 36 hours or less from the time of packaging.
