Embodiment

[0031] Relative to 5 g of gallic acid (which is expressed as 1.0 in terms of mass ratio in Table 1), mix the transition metal compound and the carbonic acid-based basic compound in the proportions shown in Table 1, and mix rapidly with a mortar until each particle is thin and uniform. until. The obtained sample was subdivided so that the amount of gallic acid might be 0.05 g in an aluminum laminate packaging bag in which nylon / aluminum foil / polyethylene was laminated. After the oxygen absorber was charged, it was heat-sealed into a square bag type and sealed so that the volume (air volume) of the packaging bag was 106 milliliters (mL). After storage at room temperature for 14 days, the oxygen concentration in the air in the packaging bag was measured, and the oxygen absorption capacity of the oxygen absorber was calculated (Examples 1 to 18).

[0032] For comparison, an oxygen absorber containing no transition metal compound and containing gallic acid and a carbonic acid-base...

Abstract

The oxygen absorber of the present invention contains gallic acid and a transition metal compound; in addition, it may contain an alkali carbonate whereby the oxygen absorbent provides safety and the same oxygen absorption capability as the oxygen absorber using iron powder.

Description

technical field [0001] The present invention relates to an oxygen absorbing agent, an oxygen absorbing resin composition, and an oxygen absorbing film that are preferably used in foods, pharmaceuticals, pharmaceuticals, cosmetics, electronic parts, and the like. Background technique [0002] In foods, pharmaceuticals, pharmaceuticals, cosmetics, electronic parts, and the like, the oxygen absorber is enclosed in a package. As the oxygen absorber, an oxygen absorber using iron powder as the main agent for the reaction, and an oxygen absorber using an organic substance as the main agent for the reaction are known. From the viewpoints of cost, oxygen absorption capacity, etc., iron powder is generally used as the main agent. oxygen absorber. However, the oxygen absorber mainly composed of iron powder (1) reacts in metal detectors used for foreign object inspection in the manufacturing process of food, pharmaceuticals, pharmaceuticals, cosmetics, electronic parts, etc., and (2) ...
