1. A method for storing and shipping edible food comprising:
- (a) placing food in a plurality of packages and wrapping each package with a permeable material, wherein a first package comprises a depression wherein food is deposited and permeable material is placed over the depression and makes contact with the food;
(b) stacking packages, wherein a second package is stacked directly on top of the first package without the underside of the second package contacting the permeable material in contact with the food within the first package;
(c) introducing gas into the first and second packages to replace air from the first and the second packages;
(d) placing the first and the second packages in a container;
(e) introducing the same or different gas into the container; and
(f) closing the container so as to prevent gas from escaping, wherein the first package has first and second sidewalls disposed opposite to each other around the depression, wherein the first and second sidewalls define a first and second crest, respectively, at the upper portions thereof, wherein the second package has third and fourth sidewalls disposed opposite to each other around the depression, wherein the third and fourth sidewalls comprise first and second flaps hinged at a periphery of the depression, whereupon folding the first and second flaps down defines a first and second concave indentation at or near to the base so that the first and second concave indentations of the second package rest on top of the first and second crests, respectively, of the first package.

12. A method for packaging food to minimize the formation of metmyoglobin on the surfaces of the food, comprising:
-
(a) placing food in a tray and wrapping the tray with a gas permeable material, wherein the tray comprises a depression formed from a tray base and any number of sidewalls, wherein the food is deposited within the depression and the material is placed over the depression and contacts the food at a location; and (b) stacking a second tray directly on top of the first tray without the underside of the second tray contacting the material at the location at which the material is in contact with the food of the first tray so as to allow oxygen to diffuse across the material that is in contact with the food and minimize the oxygen surrounding the food that may cause metmyoglobin formation wherein the first tray has first and second sidewalls disposed opposite to each other around the depression, wherein the first and second sidewalls define a first and second crest, respectively, at the upper portions thereof, wherein the second tray has third and fourth sidewalls disposed opposite to each other around the depression, wherein the third and fourth sidewalls comprise first and second flaps hinged at a periphery of the depression, whereupon folding the first and second flaps down defines a first and second concave indentation at or near to the base so that the first. and second concave indentations of the second tray rest on top of the first and second crests, respectively, of the first tray. - View Dependent Claims (13, 14, 15)

16. A method for packaging and stacking trays to minimize the deleterious effects of oxygen on food, comprising:
-
(a) overwrapping a first tray containing food therein with an oxygen permeable material so that the material contacts the food and holds the food to the tray; (b) placing a second tray directly on top of the first tray without the underside of the second tray touching the portions of the material that hold the food to the first tray; (c) placing the first and second trays in a container wherein the oxygen content is lower in the container as compared to the first tray to allow oxygen to pass through the permeable material that is touching the food into the container having the lower oxygen content wherein the first tray has first and second sidewalls disposed opposite to each other around the depression, wherein the first and second sidewalls define a first and second crest, respectively, at the upper portions thereof, wherein the second tray has third and fourth sidewalls disposed opposite to each other around the depression, wherein the third and fourth sidewalls comprise first and second flaps hinged at a periphery of the depression, whereupon folding the first and second flaps down defines a first and second concave indentation at or near to the base so that the first and second concave indentations of the second tray rest on top of the first and second crests, respectively, of the first tray. - View Dependent Claims (17, 18)
