Method for distributing a myoglobin-containing food product
A method of distributing or commercializing fresh meat having the general steps of butchering a slaughtered animal into a plurality of retail cuts; packaging the retail cuts into a plurality of articles wherein each article comprises a polymeric oxygen barrier film having a transparent portion in contact with at least a portion of the fresh meat product; transporting the packaged article to a retail outlet, wherein the packaged article is adapted for retail display and sale without removing the polymeric film and wherein the fresh meat product has a desirable appearance especially a desirable red color e.g. having an “a*” value of at least about 15 for the fresh beef product or of at least about 6 for a fresh pork or fresh poultry product and the color is maintained for at least five days and up to four weeks or more after display.
1. A method for commercializing a fresh meat product comprising a fresh beef, fresh pork, or fresh poultry product having a water content of at least 5 percent by weight and a sodium chloride content of less than 1 percent by weight comprising:
(a) butchering a slaughtered animal into a plurality of retail cuts;
(b) packaging the retail cuts into a plurality of articles wherein each article comprises a polymeric oxygen barrier film having a transparent portion in contact with at least a portion of the fresh meat product and having a myoglobin blooming agent selected from nitric oxide donating compounds, wherein the nitric oxide donating compounds comprise Fremy's salt, nitrate salts having the formula MNO 3 , nitrite salts having the formula MNO 2 or combinations thereof, wherein the counter ion M+ is selected from the group consisting of alkali metals, alkaline earth metals, transition metals, protonated primary, secondary or tertiary amines, quatemary amines and ammonium;
(c) transporting the packaged articles to a retail outlet,
wherein the packaged article is adapted for retail display and sale without removing the polymeric film and wherein the fresh meat product has a color with an “a*” value of at least about 15 for the fresh beef product or of at least about 6 for the fresh pork or fresh poultry product and the color is maintained for at least five days after display.
2. A method as in claim 1 wherein the fresh meat product comprises a fresh beef product and the fresh beef product has a color with an “a*” value of at least about 15.
3. A method as in claim 1 wherein the fresh meat product comprises a fresh pork product and the fresh pork product has a color with an “a*” value of at least about 6.
4. A method as in claim 1 wherein the fresh meat product comprises a fresh poultry product and the fresh poultry product has a color with an “a*” value of at least about 6.
5. A method as in claim 1 wherein the polymeric film comprises a multilayer film having a food contact layer and an oxygen barrier layer.
6. A method as in claim 5 wherein the food contact layer comprises polyolefin, polyester, polyamide, polystyrene, ionomer, polyacrylonitrile, or blends thereof.
7. A method as in claim 5 wherein the oxygen barrier layer comprises PVDC, EVOH, polyamide, polyester PVOH, nanocomposite, metal, metallized film, metal-oxide coated film, polyacrylonitrile, methyl acrylate copolymer or combinations thereof.
8. A method as in claim 1 wherein the myoglobin blooming agent is on, in or able to migrate to the transparent portion of the polymeric film in contact with the portion of the fresh meat product.
9. A method as in claim 8 wherein the transparent portion comprises between about 0.01 to about 10 μmole myoglobin blooming agent per square inch of the transparent portion.
10. A method as in claim 1 wherein the transparent portion comprises an amount of myoglobin blooming agent sufficient to cause the surface of the fresh meat product to have a visible red hue at least 10 days after packaging the fresh meat product in a vacuum environment.
11. A method as in claim 1 wherein the packaging step further comprises reducing oxygen from an environment surrounding the fresh meat product.
12. A method as in claim 11 wherein reducing oxygen is by vacuum to produce a vacuum package.
13. A method as in claim 5 wherein the packaged article is adapted for retail display and sale without removing the oxygen barrier layer of the polymeric film.
14. A method as in claim 1 wherein the food packaging article further comprises indicia.
15. A method as in claim 14 wherein the indicia is selected from the group consisting of a packed on date a sell by date, a use by date and combinations thereof.
16. A method as in claim 14 wherein the indicia comprises a sell by date which is at least about 20 days following the date of packaging.
17. A method as in claim 16 wherein the sell by date is at least about 30 days following the date of packaging.
18. A method as in claim 1 wherein transporting is in a refrigerated environment.
19. A method as in claim 1 comprising the additional step of slaughtering an animal.
