A multilayer nonporous oxygen absorbing structure that resists delamination, e.g., humidity induced delamination, including a first layer having a first continuous polymer phase, a first water insoluble, dispersed, polyether resin phase in the first continuous polymer phase, and a water activated oxygen absorber, and a second layer having a second continuous polymer phase, bonded to the first layer.

A humidity control device for use in maintaining the desired humidity of a closed environment, e.g., a container, while also decreasing headspace oxygen, the device including a water vapor and oxygen permeable pouch, an aqueous salt solution containing humidity controlling salts in combination with salts of ascorbic acid or isomers thereof.

Provided are methods of preserving and/or storing Synsepalum dulcificum berry, which may involve separating a pulp of the berry into two or more parts; and freeze drying the berry with the separated pulp.

A process for producing an oxygen absorbing agent includes treating an alloy with an aqueous solution of an acid or an alkali, the alloy including at least one transition metal selected from the group consisting of manganese, iron, platinum, and copper group metals and at least one metal selected from the group consisting of aluminum, zinc, tin, lead, magnesium, and silicon to elute and remove at least a part of the component; and subjecting the alloy obtained by removing at least a part of the component in the alloy to treatment with an aqueous solution of a salt of an inorganic acid or a salt of an organic acid that can form a salt with the transition metal as the component, to form a metal salt in at least a part of the surface of the alloy.

The preservation or extension of the life of oxygen perishable products such as fresh or cooked meats; fresh vegetables and fruits; dried vegetables, fruits and meats; packaged pharmaceuticals or biologicals; open and enclosed marketing display cases of meats, fruits and vegetables; and packaging, warehousing and transportation of meats, fruits, and vegetables is obtained by subjecting such products to an atmosphere obtained from gas permeable packets of an oxygen scavenging composition comprising a sodium carbonate mineral and one or more carboxylic acids. When the environment surrounding the oxygen perishable product is subjected to the packets of gaseous permeable oxygen scavenging compositions, oxygen is taken in by the scavenging composition and also the presence of carbon dioxide in the surrounding environment is enhanced thereby minimizing or eliminating the effect the oxygen on the oxygen perishable products.
