Abstract

The present invention provides a novel oxygen absorbent composition being capable of realizing an oxygen absorbent not responding to a metal detector, being suppressed in the increase of the odor intensity after the absorption of oxygen and having an excellent oxygen absorption performance over a wide range of humidity conditions from low humidity to high humidity, and provides an oxygen absorbent package using the oxygen absorbent composition. The oxygen absorbent composition of the present invention includes at least one compound having a tetralin ring represented by the following general formula (1) and a transition metal catalyst:
