The present invention relates to a method for packaging foods that generates carbon dioxide gas during storage. 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 gas, they must be in the form of an aqueous solution or must be provided with at least 10% water. 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 amanatto beans, the water in the carbon dioxide gas absorbent transfers to the food. It was actually difficult to do so. 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 with an initial moisture content of about 10%, foods etc. become damp during packaging. Also, barium hydroxide (Ba(OH) 2 8H 2 O) 11
It is known that an absorbent consisting of 74% calcium hydroxide (Ca(OH) 2 ), 5% calcium hydroxide (KOH), and 10% water similarly absorbs much more carbon dioxide. Unfortunately, because it releases moisture when it absorbs gas, it has not been possible to place it in a package to preserve foods, etc. As described above, conventionally known carbon dioxide absorbents have the major problem of requiring moisture to be added in advance and, furthermore, releasing moisture through reaction when absorbing carbon dioxide. The present invention solves these problems,
This is a food packaging method that does not require the addition of water from the beginning and uses a carbon dioxide absorbent that can absorb and remove released water within the composition. Furthermore, the present invention can be used as a composition that has a combined effect as a desiccant, depending on the component composition of the composition. The present invention will be explained in detail below. The present invention provides a carbon dioxide absorbent in which a deliquescent substance and a porous inorganic substance with a large specific surface area are uniformly mixed with one of alkali metal hydroxides, alkaline earth metal hydroxides, or a mixture thereof. This is a food packaging method using The alkali metal hydroxides used are:
Examples of sodium hydroxide, potassium hydroxide, and alkaline earth metal hydroxides include calcium hydroxide, barium hydroxide, and magnesium hydroxide. Further, examples of deliquescent substances include hydrates of calcium chloride, sodium carbonate, and the like. Furthermore, examples of porous inorganic materials having a large specific surface area include activated carbon, zeolite, silicon dioxide, and the like. When mixing these substances, it is preferable that they be in the form of powder, but in the case of porous inorganic materials, they may be in the form of granules. In addition, all of the above substances are used in powder form, and
It is also possible to add crystalline cellulose or the like which does not participate in the reaction to this absorbent and use the absorbent itself as granules using a granulator. Furthermore, it is also possible to use these absorbents in the form of tablets using a gun machine. As described above, the carbon dioxide absorbent used in the present invention may be in any form such as powder, granules, tablets, etc. at the time of use. In the case of alkaline earth metal hydroxide powder, the blending ratio of the absorbent used in the present invention is 0.1 part by weight of the deliquescent substance to 1 part by weight of the alkali metal hydroxide powder.
It is preferable to mix in a range of 2 parts by weight. In addition, in the case of alkaline earth metal hydroxide powder,
The deliquescent substance is preferably mixed in an amount of 0.5 to 2 parts by weight per 1 part by weight of the alkaline earth metal hydroxide powder. Next, specific composition examples of the present invention will be explained. Composition example (1) Sodium hydroxide (or potassium hydroxide)
Powder 100 parts by weight Calcium chloride (dihydrate or hexahydrate)
Powder 50-150 〃 Activated carbon powder 5-15 〃 (2) Sodium hydroxide (or potassium hydroxide)
Powder 100 parts by weight Sodium carbonate (decahydrate) powder
10-70 〃 Activated carbon powder 5-15 〃 Zeolite powder (or granules) 10-20 〃 (3) Calcium hydroxide powder 100 parts by weight Calcium chloride (dihydrate or hexahydrate)
Powder 50-150 〃 Activated carbon powder (or silicon dioxide, calcium silicate powder) 5-15 〃 (4) Potassium hydroxide powder 20-50 parts by weight Calcium hydroxide powder 50-100 〃 Calcium chloride (dihydrate or 6 parts by weight) hydrate)
Powder 50-150 〃 Activated carbon powder (or silicon dioxide, calcium silicate powder) 5-15 〃 (5) Calcium hydroxide powder 50-100 parts by weight Barium hydroxide (octahydrate) powder
20～50 〃 Calcium chloride (dihydrate or hexahydrate)
Powder 50-150 Activated carbon powder 5-15 (6) Calcium hydroxide powder 100 parts by weight Calcium chloride (dihydrate or hexahydrate)
Powder 50-150 〃 Activated carbon powder 5-10 〃 Zeolite powder (or granules) 20-50 〃 Various combinations such as the above are possible, and it is difficult to distinguish between them, but it is important to consider ease of handling, safety, etc. For example, a composition as described below is desirable. Namely (a) Calcium hydroxide powder 50 to 100 parts by weight Calcium chloride dihydrate powder
50-100 〃 Activated carbon powder 5-10 〃 (b) Calcium hydroxide powder 50-100 parts by weight Barium hydroxide octahydrate powder 10-15 〃 Calcium chloride dihydrate powder
50-1000 〃 Activated carbon powder 10-20 〃 (c) Calcium hydroxide powder 50-100 parts by weight Sodium carbonate decahydrate powder 30-50 〃 Activated carbon powder 5-10 〃 Zeolite powder 5-10 〃 Herein, the present invention The role of the inorganic powder with a large specific surface area used is to promote the reaction.
When using a single substance, the specific surface area is
It is preferable that the water absorption capacity is around 500 to 1000 m 2 /g and that the water absorption capacity is not very large. It is more effective to use zeolite together with activated carbon. The carbon dioxide absorbent used in the present invention can be used in the form of powder, granules, or tablets, but depending on the purpose, if it is used sandwiched between nonwoven fabrics, it may be placed in a paper/perforated polyethylene bag. When used as a container, tablets of the above-mentioned composition may be placed in the bottom of the container. Examples will be shown below and explained in more detail. Example 1 Absorbents consisting of the following compositions A and B (5 g each) were filled and sealed in Japanese paper (40 g/m 2 )/open-hole polyethylene film (35 μ) sachets, and 100 coffee beans were
along with polyvinylidene chloride coated stretched polypropylene (20μ)/polyethylene (40μ) bag (150×
200m/m size), sealed and stored in a room at approximately 25°C. After storage, the gas concentration inside the package and the moisture content of the coffee beans were measured.

し得るものである。[Table] As described above, it was confirmed that in the present invention, 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. This is because the packaging of regular coffee beans or regular coffee beans cannot prevent the generation of carbon dioxide gas. Packaging materials that are easily permeable to carbon dioxide, such as nylon/
Polyethylene bags are used, or bags equipped with a valve that allows pressure to be released to the outside when the inside of the package is pressurized. There is no swelling of the body, and
This is extremely excellent because it does not add moisture to the coffee beans. Furthermore, since a gas barrier packaging material can be used, it is possible to package the product with extremely little influence from oxygen permeation from the outside. Example 2 When product A of the present invention in Example 1 was similarly packaged with amanatto and checked for carbon dioxide generation and absorption during storage, carbon dioxide generation was intense when unused, and the package was kept for a week. Even though the bag was destroyed afterwards. In the present invention, no carbon dioxide gas was detected after one week. 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 as delicious as the product immediately after packaging. In the above examples, the purpose is to preserve foods that generate carbon dioxide gas, but other uses can be considered for conventional carbon dioxide absorbents (for example, trade names Bara Lime, Soda Lime, etc.). It is more efficient than ever before, and can be applied to respiratory gas measuring devices, basal metabolic rate measuring devices, closed circulation anesthesia machines, etc., with greater efficiency and fewer obstacles.
