た。 However, conventional ascorbic acid-based oxygen scavengers have poor fluidity as a powder, and have the following practical drawbacks. Oxygen scavengers are used by filling and packaging an oxygen-absorbing composition in a breathable packaging material and enclosing this together with food in a sealed system. Die-roll and bar seal automatic filling and packaging machines are used. In the case of automatic packaging, if the oxygen absorber does not have good fluidity as a powder, it is difficult to accurately measure it during automatic packaging, and moreover, the oxygen absorbing composition may not be present in the area where the packaging material is sealed. There was a drawback that they were sealed together. In order to improve these drawbacks, some attempts have been made to granulate the above composition, but since fillers such as activated carbon are used, granulation cannot be achieved unless a large amount of binder is used, and if a large amount of binder is used, oxygen The drawback was that the absorption of water was inhibited.
