Oxygen absorbing composition, oxygen absorbing resin composition using the oxygen absorbing composition, and preserving method utilizing these compositions

摘要

Provided is an oxygen absorbing composition and an oxygen absorbing resin composition employing such oxygen absorbing composition, which demonstrate a favorable oxygen absorbing performance even in a low-humidity environment. Use of such oxygen absorbing composition and oxygen absorbing resin composition allows preservation of medicines or foods etc. which are in a dry state and disfavoring moisture.The oxygen absorbing composition according to the present invention comprises iron powder/iodine, or iron powder/iodine/metallic iodine.
