シート状脱酸素剤に関する発明である。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a sheet-shaped oxygen absorber. For more details,
This invention relates to a sheet-shaped oxygen absorber characterized by forming a composition containing a fibrous substance, iron powder, water, and an electrolyte into a sheet by papermaking.

酸素を脱酸素することによって食品の保存を行うもので
ある。Conventionally, oxygen scavengers have been used in which a pouch made of a breathable packaging material is filled with a chemical containing iron powder or a reducing organic substance as a main ingredient. This oxygen absorber package is hermetically sealed together with an object to be preserved, such as food, in a bag made of a non-breathable packaging material, and the food is preserved by deoxidizing the oxygen inside the bag.

れらの欠点を除くために種々の研究を行った結果本発明
を完成するに至った。Conventional oxygen absorbers in the form of sachets have the following drawbacks. In other words, (1) there is a risk of accidental ingestion as it is enclosed in a bag with food; (2) there is a limit to the size of oxygen absorbers and it is not possible to make extremely small ones, so storage space is limited. (3) If the lid of the container is small, it cannot be fixed. (4) If the size of the bag containing the substance to be preserved is small, for example, about 30 mm, it cannot be applied to the bag. (5) When fixing it to the tray, the thickness becomes too large, making it difficult to manufacture and fix the tray. (6) The bulk powder of the oxygen absorber in the bag tends to clump, so it cannot be easily sealed with air. The contact area becomes small, and in order to obtain the desired oxygen removal rate, a large excess of oxygen scavenger bulk powder is required compared to the potential oxygen absorption capacity. As a result of conducting various studies to eliminate these drawbacks, the present invention has been completed.
