Abstract:
A method of reducing the oxygen concentration in an enclosed space comprising:a. placing an oxygen scavenging packet within said enclosed space, said oxygen scavenging packet comprising: i. an oxygen permeable material formed into a closed packet; and ii. an oxygen absorber within said closed packet, said oxygen absorber comprising iron; and b. introducing a liquid oxygen uptake accelerator comprising water directly onto said oxygen absorber, wherein said liquid oxygen uptake accelerator is introduced in an amount relative to the amount of said oxygen absorber, such that when the oxygen uptake accelerator and oxygen absorber are brought into contact, the oxygen absorber is capable of reducing the oxygen content of a predetermined volume containing about 2 vol % oxygen to less than 0.5 vol % oxygen at a temperature of about 34Â° F. in no more than 90 minutes after said oxygen uptake accelerator and oxygen absorber are brought into contact, said oxygen uptake accelerator being present in said packet in an amount between about 0.2 and 1.4 mL per 2.5 grams of iron.
