Image Oxygen absorber.jpeg thumb right An oxygen absorber Image Oxygen Absorber.JPG thumb right The contents of an oxygen absorber from a packet of Jerky food beef jerky. An oxygen absorber is a small packet of material used to prolong the shelf life of food. They are used in food packaging to prevent food colour change, to stop oils in foods from becoming Rancidification rancid , and also the growth of oxygen using aerobic microorganisms such as fungi . Oxygen supports the growth of microorganisms and causes changes in color and rancid odors in packaged foods. Plastic packaging is less able to exclude oxygen from packaged foods than are the older glass and metal containers. Oxygen absorbers absorb oxygen and effectively reduce the aerobic environment to 0 oxygen. Therefore aerobic bacteria and fungi are unable to grow in this environment. This will extend the shelf life of a food product from 1 week to several months. The advantages of oxygen satchels versus vacuum packaging are that the food products are not crushed or squeezed, as some products are of high value and are fragile, and its simplicity of use. The packaging itself and the food bag container seal are crucial for the effectiveness of the oxygen absorber. A minor packaging fault or leak can render the oxygen absorber useless and the contents inside the package will perish. Thus, high barrier packaging with a low oxygen transmission rate and efficient seal techniques need to be employed. ref cite web last Cichello first Dr. Simon title A Guide to Oxygen Absorbers url http www.oxygenabsorber.net Oxygen 20Absorbers 20Introduction.pdf publisher Wholesale Group International Pty Ltd accessdate March 2010 ref Oxygen absorbers are made in different formulations to match the water activity of the foods they are protecting.

no footnotes date November 2011 Oxygen equivalent compares the relative amount of oxygen available for respiration at a variable pressure to that available at Standard Ambient Temperature and Pressure SATP . As external respiration depends on the exchange of gases due to partial pressures across a semipermeable membrane and normally occurs at SATP, an oxygen equivalent may aid in recognizing and managing variable oxygen availabiity during procedures such as hyperbaric oxygen therapy or medical air transport . It does so by expressing oxygen concentration as a ratio of the partial pressure of oxygen at a given altitude or pressure to Standard Atmospheric Pressure rather than as a ratio of the PO sub 2 sub at a given pressure to the total pressure of the gas mixture. The latter would generally be 0.2095, the atmospheric concentration by volume of O sub 2 sub , although FO sub 2 sub and P sub atm sub vary for extraterrestrials. Calculations occur as follows Let O sub 2 sub E be oxygen equivalent, FO sub 2 sub be the fractional concentration of oxygen, P sub atm sub generally 760 mmHg, barring intergalactic travel , P sub b sub be the barometric pressure, and dP be the change in pressure at a given altitude. Then, O sub 2 sub E FO sub 2 sub P sub b sub dP P sub atm sub It is worthwhile to note that pressures may often be expressed in units of distance such as feet when diving. For this, note that descending 33 ft in salt water or 33.9 ft in fresh water results in a change of 1 atm, so distance and pressure are used interchangeably in this context.

Unreferenced date December 2009 The Oxygen Destroyer was a fictional weapon that appeared in the 1954 film Godzilla 1954 film Godzilla . It was an extremely powerful chemical compound that was able to completely dissolve Godzilla and wipe out all life in the Tokyo Bay . It was also the only weapon that was truly effective against the monster. Unintentionally discovered by Daisuke Serizawa during his experiments, the Oxygen Destroyer dissolved oxygen in water which instantly reduced any and all organic life within range to its skeletal frame. While it s never explained how removing oxygen causes such a destructive reaction, since the conservation of mass laws regarding the conservation of mass state that matter and energy can t be destroyed but only converted into another form, it s possible that the Oxygen Destroyer actually converts oxygen into an entirely different element with highly corrosive properties. In the film, Serizawa was hesitant to use his discovery for fear of the damage it would cause and political implications therein, but ultimately relented when he realized Godzilla was the greater threat. But to prevent the formula from being perverted into a wholesale weapon of mass destruction he destroyed his research documents and subsequently took his own life. In Godzilla vs. Destoroyah 1995 , it is revealed that the Oxygen Destroyer awakened and mutated Precambrian life forms that lived in Tokyo Bay that would merge to form the strongest Kaiju ever recorded taking Godzilla at the peak of his power, Godzilla Junior and Super X combined to finally destroy him Destoroyah .
