に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deoxidizer that absorbs oxygen and generates carbon dioxide. Specifically, regarding ascorbic acid-based oxygen absorbers that are enclosed with products that require anoxic conditions such as food deterioration prevention, the deoxidation time is fast,
The present invention relates to a deoxidizer that generates carbon dioxide gas with the absorption of oxygen in a package.

の悪変を完全に防止することはできなかった。BACKGROUND OF THE INVENTION During storage, food is transformed by oxygen in the air. Specifically, problems such as proliferation of bacteria and molds, rancidity of fats and oils, generation of pests, deterioration of flavor, discoloration, and the like occur. Oxygen in the air is involved in these phenomena, and oxygen has been cut off from foods. For example, vacuum packaging and nitrogen gas replacement are performed, but these methods cannot completely remove oxygen in the packaging, and thus cannot completely prevent the food from changing.

た。As another method, a food is sealed in an airtight bag together with an oxygen scavenger. Examples of the oxygen scavenger include those utilizing the oxidation reaction of iron powder and those utilizing the oxidative decomposition reaction of organic compounds such as ascorbic acid and catechol. By the way, recently, many food factories have introduced a metal detector in order to prevent foreign substances from being mixed. A deoxidizer using iron powder has a high reaction rate, but is detected by a metal detector. Further, in the case of the iron-based deoxidizer, the volume in the package is reduced by the amount of the absorbed oxygen, and there is a possibility that the appearance is damaged or the form of the food is broken.

中の酸素と反応することを利用している。As an oxygen scavenger which is not detected by a metal detector, there is an oxygen scavenger utilizing an oxidation reaction of ascorbic acid (Japanese Patent Publication No. 58-29069, Japanese Patent Publication No. 62-24067). They utilize the fact that ascorbic acid reacts with oxygen in the air when water is present in the presence of ascorbic acid using a metal compound or activated carbon as a catalyst under strongly alkaline conditions using an alkali metal hydroxide or an alkali metal carbonate.

た。[0005] In the case of an ascorbic acid-based oxygen scavenger, when an alkali metal or an alkaline earth metal hydroxide is used as an alkaline substance, only an oxygen absorbing function is exhibited. When an alkali metal carbonate is used, carbon dioxide gas is generated with the absorption of oxygen, so that the volume in the package does not decrease. However, in the case of an oxygen scavenger utilizing the oxidation reaction of ascorbic acid, the deoxygenation reaction is slow, so its use has been limited in preventing relatively long time-consuming deterioration such as mold generation of dry food and rancidity of fats and oils. .
