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; and e) transporting or storing the material in the tote. |
