Abstract

PURPOSE: To obtain an oxygen absorbent capable of indicating the presence of exygen by adding a substance discoloring when subjected to oxidation or reduction to a substance capable of absorbing oxygen without causing discoloration.
CONSTITUTION: A substance capable of absorbing oxygen having also an exygen indicator function as well as a light color or cloroless but causing no discoloration even when absorbing oxygen, e.g., hydrisylfite, etc., is mixed with a substance which causes discoloration when subjected to oxidation or reduction, e.g., iuazine dyes, indigo dyes, etc., and then the mixture is housed in a gas-permeable container. The oxygen absorbent has a high sensitivity to the presence of oxygen.
