The pieces cut into cm pieces were integrated with an oxygen absorber using a commercially available bond in the same manner as in Example 1 to obtain a composite oxygen absorber. When this composite oxygen absorber was placed in a commercially available candy bag with gas barrier properties (capacity 200) along with normal air and sealed in the usual manner, after 24 hours it was integrated with the oxygen absorber. The oxygen detector had changed color from blue to pink. Furthermore, when the bag was opened, the oxygen detector changed color from pink to blue again.

Gas-permeable Japanese paper coated with polyethylene on the inside was immersed in an aqueous solution containing 55 parts by weight of a mannose aqueous solution and 15 parts by weight of a 10% potassium hydroxide aqueous solution, taken out, and air-dried. The obtained Japanese paper was used as a packaging material for an oxygen absorber, and the same oxygen absorber as in Example 1 was encapsulated to obtain a composite oxygen absorber. When this composite oxygen scavenger was left in a closed container in the same manner as in Example 1, the enveloping material had changed color from blue to colorless after 30 hours. The oxygen concentration inside the container at this time was 0.05% by volume. moreover,
When this container was opened, the packaging material of the oxygen absorber changed color from colorless to blue again.

In addition, by using the obtained composite oxygen absorber, the oxygen in the sealed container or packaging can be absorbed to create a good oxygen-free state, and the presence or absence of oxygen in the container or packaging can be reversible. It was easily detected with the naked eye due to the color change.

未封入等に基づくトラブルが完全に防止される。C Effects of the Invention As explained above, the composite oxygen absorber of the present invention, which integrates an oxygen detector and an oxygen absorber, has both oxygen detection and oxygen absorbing functions, and can be used in oxygen absorbing packaging. It is possible to easily and efficiently manage oxygen-free conditions such as air-tight containers and closed containers. Moreover, the composite oxygen absorber of the present invention is easy to handle, and it is possible to speed up the work of enclosing the oxygen absorber and oxygen detecting agent in an oxygen absorbing package or the like. Furthermore, when the composite oxygen absorber of the present invention is used, troubles caused by not including an oxygen absorber or an oxygen detector can be completely prevented.
従って、本発明の複合脱酸素剤は、最近急速に普及して
きた食品の脱酸素包装等の際に好適に使用される。Therefore, the composite oxygen absorber of the present invention is suitably used in oxygen-absorbing packaging of foods, which has recently become rapidly popular.
