<p>PROBLEM TO BE SOLVED: To provide an oxygen absorbing body having excellent oxygen absorptive property and scarcely emitting malodor by producing an oxygen absorptive resin composition, which is a composition to be produced by mixing and kneading a metal-based oxygen absorbing agent and a thermosetting resin and contains practically no hindered phenolic antioxidant. SOLUTION: An oxygen absorbing body to be used for preserving food is produced using an oxygen absorptive resin composition produced by mixing and kneading a metal-based oxygen absorbing agent and a thermosetting resin as to obtain an oxygen absorbing body containing practically no hindered phenolic antioxidant, which causes malodor component emission. Moreover, tocopherol may be added. As the metal-based oxygen absorbing agent, a ferric one is preferably from the viewpoints of oxygen absorbing function and handling property and especially partially oxidized iron oxide powder is used. The oxygen composition ratio of the partially oxidized iron oxide powder by an element analysis method is controlled to be 0.8wt.% or higher and not more than 10wt.%. As the thermosetting resin, polyolefin resin may be used.</p> |
