用されている。2. Description of the Related Art As one of techniques for preserving food, there is a technique using an oxygen scavenger, which is used to prevent mold, oxidation, and discoloration of food. As the oxygen scavenger, those containing iron as a main component and those containing an organic substance such as ascorbic acid as a main component are known. Some food manufacturers use metal detectors to control the quality of products by using metal detectors to prevent foreign substances such as needles and nails from entering the products. Food manufacturers using such metal detectors cannot use iron-based oxygen scavengers and use organic scavengers such as ascorbic acid.

険性があった。The ascorbic acids used as the main component of the non-ferrous oxygen scavenger are organic compounds and combustibles. Activated carbon used as a filler for ascorbic acids is also a designated combustible in the Fire Service Law (coal, charcoal). Since these oxygen absorbers absorb oxygen by the oxidation reaction of ascorbic acids, they generate heat during the reaction. If oxygen is absorbed in a state where a large amount of these oxygen absorbers are accumulated, heat generated by the oxidation reaction is stored, which accelerates the oxidation reaction, and as a result, there is a danger that the combustibles in the composition may spontaneously ignite. Was. Also, even if these oxygen scavengers are used in a small amount, if the ambient temperature is increased, the oxidation reaction is accelerated and a sudden heat is generated, and there is also a risk of spontaneous ignition.
