Disclosed are packaging systems and methods useful in extending the storage-life of foodstuff such as fresh fish. The packaging systems and methods can be used to transport or store the foodstuff for an extended period of time. The packaging systems preferably employee a high headspace and flexible architecture and may use a fuel cell to maintain a reduced oxygen level in a high carbon dioxide environment surrounding the foodstuff. Also disclosed are methods useful in extending the storage-life of foodstuff such as fresh fish. The methods can be used to transport or store the foodstuff for an extended period of time. The methods preferably use a low oxygen gas source to maintain a reduced oxygen level in the environment surrounding the foodstuff.

1. A method for transporting and/or storing of carbon dioxide absorbing oxidatively-degradable foodstuffs which comprises: a) removing the oxygen in a packaging module containing an carbon dioxide absorbing oxidatively-degradable foodstuff to generate a reduced oxygen environment within the packagin
1. A method for transporting and/or storing of carbon dioxide absorbing oxidatively-degradable foodstuffs which comprises: a) removing the oxygen in a packaging module containing an carbon dioxide absorbing oxidatively-degradable foodstuff to generate a reduced oxygen environment within the packaging module, the packaging module comprising a pressure-stable sealable tote of limited oxygen permeability and a gaseous headspace wherein said tote consists of a flexible, collapsible or expandable material which does not puncture when collapsing or expanding, a fuel cell, and a hydrogen source, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 10 cubic centimeters/100 square inch/24 hours/atm;b) flushing the tote with an inert gas such that the initial gaseous headspace occupies at least 30 volume percent of the tote and the gas in the initial gaseous headspace comprises at least 99 volume percent gases other than oxygen, and no more than about 20% of the initial gaseous headspace of the tote is in the horizontal direction, with the remainder of the initial gaseous headspace being in the vertical direction;c) sealing the tote;d) operating the fuel cell during transport or storing such that oxygen is converted to water by the hydrogen present in the tote to maintain the reduced oxygen environment within the tot;wherein an anode of the fuel cell is in communication with the hydrogen source and a cathode inlet of the fuel cell is in communication with the environment in the tote and in a presence of the oxygen in the environment in the tote, protons and electrons are generated by the anode, and the protons interact with the oxygen present at the cathode to generate water and to remove the oxygen from the environment in the tote, wherein the fuel cell does not require an external power source to convert the hydrogen and oxygen into water; ande) transporting or storing the material in the tote. 2. The method of claim 1, wherein the gas in the initial gaseous headspace comprises at least about 90% carbon dioxide. 3. The method of claim 1, wherein the initial gaseous headspace comprises from about 30% to about 69% of the total internal volume of the tote. 4. The method of claim 1, wherein the transporting or storing is for a time period from between 5 and 50 days. 5. The method of claim 4, further comprising maintaining a temperature in the tote sufficient to maintain freshness of the material during transport or storage. 6. The method of claim 1, wherein the reduced oxygen environment comprises less than 1% oxygen. 7. The method of claim 1, wherein the reduced oxygen environment comprises carbon dioxide and/or nitrogen. 8. The method of claim 1, wherein the foodstuff is fish. 9. The method of claim 1, wherein the fuel cell is programmed to cease operation after an initial period of time that is sufficient to allow a natural minimization or cessation of gaseous exchange. 10. The method of claim 9, wherein the fuel cell is programmed to cease operation when the oxygen level reaches and is maintained below a predetermined level. 11. The method of claim 10, wherein the predetermined level of oxygen is below 5% oxygen v/v. 12. The method of claim 1, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 5 cubic centimeters/100 square inch/24 hours/atm. 13. The method of claim 1, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 2 cubic centimeters/100 square inch/24 hours/atm. 14. The method of claim 1, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 1 cubic 30 centimeters/100 square inch/24 hours/atm. 15. A method for transporting and/or storing of carbon dioxide absorbing oxidatively-degradable foodstuffs which comprises: a) obtaining a pressure-stable sealed tote of limited oxygen permeability and comprising a gaseous headspace and a carbon dioxide absorbing oxidatively degradable material, wherein the initial gaseous headspace occupies at least 30 volume percent of the tote and the gas in the initial gaseous headspace comprises at least 99 volume percent gases other than oxygen, and no more than about 20% of the initial gaseous headspace of the tote is in the horizontal direction, with the remainder of the initial gaseous headspace being in the vertical direction, further wherein the tote consists of a flexible, collapsible or expandable material which does not puncture when collapsing or expanding, and further wherein the tote is connected to a module comprising a fuel cell and a source of hydrogen such that the anode of the fuel cell is in direct communication with the environment of the tote, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 10 cubic centimeters/100 square inch/24 hours/atm;b) operating the fuel cell during transport or storing such that oxygen in the tote is converted to water by the fuel cell, wherein an anode of the fuel cell is in communication with the hydrogen source and a cathode inlet of the fuel cell is in communication with the environment in the tote and in a presence of the oxygen in the environment in the tote, protons and electrons are generated by the anode, and the protons interact with the oxygen present at the cathode to generate water and to remove the oxygen from the environment in the tote, wherein the fuel cell does not require an external power source to convert the hydrogen and oxygen into water; andc) transporting or storing the material in the tote. 16. The method of claim 15, wherein the gas in the initial gaseous headspace comprises at least about 90% carbon dioxide. 17. The method of claim 15, wherein the initial gaseous headspace occupies from about 30 to about 35% of the internal volume of the tote. 18. The method of claim 15, wherein the module is disconnected from the tote after an initial period of time that is sufficient to allow a natural minimization or cessation of gaseous exchange. 19. The method of claim 15, wherein the module is disconnected from the tote when the oxygen level reaches and is maintained below a predetermined level. 20. The method of claim 15, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 5 cubic centimeters/100 square inch/24 hours/atm. 21. The method of claim 15, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 2 cubic centimeters/100 square inch/24 hours/atm. 22. The method of claim 15, wherein the limited oxygen permeability comprises an oxygen transmission rate of less than 1 cubic 30 centimeters/100 square inch/24 hours/atm.
