％程度の水分を与えなければならなかった。It has been known for a long time that alkali metal hydroxides and alkaline earth metal hydroxides absorb carbon dioxide gas very well. However, in order for these substances to efficiently absorb carbon dioxide, they must be in the form of an aqueous solution or at least 10
% of water had to be given.
このような水溶液状態や少なくとも１０％の水分を含む
炭酸ガス吸収剤を用い、例えばコーヒー豆、甘納豆等の
食品の発生する炭酸ガスを吸収除去することは、炭酸ガ

であった。更にこれらの物質はいずれも炭酸ガス乞吸収
すると共に水分を放出するため、初期１０％程度の水分
含量であっても包装中に食品等を湿メラセるという欠点
を有している。Using such an aqueous solution state or a carbon dioxide gas absorbent containing at least 10% water to absorb and remove carbon dioxide gas generated from foods such as coffee beans and sweetened soybeans, it is possible to absorb and remove carbon dioxide gas generated from foods such as coffee beans and sweet natto. The transition was virtually difficult. Furthermore, it has been practically difficult for the carbon dioxide absorbent to absorb and remove carbon dioxide gas generated by foods such as coffee beans and amanatto beans within the packaging because moisture transfers to the foods. Furthermore, since all of these substances absorb carbon dioxide gas and release moisture, they have the disadvantage that even if the initial moisture content is about 10%, foods etc. become damp during packaging.
また、水酸化バリウム（Ｂａ（ｏＨ）２・８Ｈ２ｏ）１
１％、水酸化カルシウム（Ｃａ（Ｏ）１）２） ７４％

吸収剤は同様に非常により炭酸ガスを吸収することが知

ため残念ながらそのまま食品等を保存する目的で包装内
に併置することが出来なかった。In addition, barium hydroxide (Ba(oH)2.8H2o)1
1%, calcium hydroxide (Ca(O)1)2) 74%
It is known that an absorbent consisting of 5% potassium hydroxide (KOH) and 10% water similarly absorbs a lot of carbon dioxide, but unfortunately it releases water when absorbing carbon dioxide. It was not possible to place them together in a package for the purpose of preserving food, etc.
以上のように従、来から知られている炭酸ガス吸収剤は

期の状態に保つことが出来ることが確認された。As described above, in the present invention, it has been confirmed that even after two weeks, the carbon dioxide gas in the package can be maintained at 0%, and the moisture content of coffee beans can be maintained at approximately the initial state of 2.

である。Normally, packaging for coffee beans or regular coffee cannot prevent the generation of carbon dioxide gas, so if a packaging material that is easily permeable to carbon dioxide gas, such as a nylon/polyethylene bag, is used, or if the inside of the package is pressurized, it will be released to the outside. However, in the present invention, even if a gas barrier packaging material is used, the package does not expand, and it does not introduce moisture to the coffee beans, making it extremely superior. It is something that Furthermore, since gas barrier packaging materials can be used, packaging can be achieved with extremely little influence from oxygen permeation from the outside.

When we checked the carbon dioxide generation and absorption status during storage, we found that when unused, carbon dioxide gas was generated strongly, and even though the package was torn after a week, in the present invention, carbon dioxide gas was not generated in the -week layer. was not detected. In addition, the unused product with a torn bag had a strong sour taste and was inedible, but the product of the present invention was delicious, no different from the product after packaging.
