Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used for refrigerators, freezers, frozen display stands, and other storage and display shelves for fresh foods, etc., to adsorb and remove odors generated from foods. The present invention relates to an adsorbent material used as a deodorizing material for clothing, and as a deodorizing and antifouling material for clothing.

[Conventional technology]

Conventionally, in order to remove odors generated from food in refrigerators, etc., deodorizers have been used, which are made by putting an adsorbent such as activated carbon inside a predetermined container that is air permeable to the outside. It is common practice to remove odors from the refrigerator by placing the container in a refrigerator, etc., to allow the adsorbent inside the container to adsorb and remove odors from the refrigerator. Furthermore, when storing clothing for a long period of time, insect repellents such as camphor and naphthalene are used.

[Problem that the invention seeks to solve]

However, with conventional deodorizers such as those mentioned above, the container containing the adsorbent such as activated carbon occupies a part of the internal space of the refrigerator, causing a loss of space for storing food, and the internal space is In addition to deforming the shape of the deodorizer and deteriorating its storage efficiency, when the deodorizer is installed inside the refrigerator, the odor inside the refrigerator is absorbed only by the adsorbent on the outer surface of the deodorizer container. Since the adsorbent located inside is inhibited by the adsorbent located outside and does not directly participate in the adsorption of odor, the adsorption efficiency of the adsorbent in the container as a whole deteriorates. Therefore, it is necessary to perform operations such as shaking the deodorizer container as needed to change the position of the adsorbent to ensure adsorption power, which is time-consuming. Furthermore, when food rots, decomposition gas is generated, which promotes deterioration and putrefaction of the food, but adsorbents such as activated carbon can absorb ethylene gas, ammonia gas, fish and meat decomposition gas, etc. Although it adsorbs to a certain extent, it cannot suppress the deterioration and decomposition of food, and a satisfactory deodorizing effect cannot be expected when bad odors are generated due to food decomposition. In addition, when storing clothing for a long period of time, not only will the clothing be damaged by the growth of mildew, but the odor of insect repellents such as camphor and naphthalene will also stick to the clothing, so be careful not to wear it. In some cases, it takes time and effort to take the insect repellent out of the drawer and dry it in the shade in order to eliminate the smell of the insect repellent, which is inconvenient when used suddenly.

In view of the above-mentioned problems, the present invention is designed to be used in refrigerators, freezers, frozen display stands, and other storage and display shelves for fresh foods, etc., by simply adsorbing odors generated from foods and decomposed gases generated when foods rot. In addition, it is possible to maintain the freshness of foods by suppressing the deterioration and progress of spoilage of foodstuffs, prevent the occurrence of bad odors due to food spoilage, and more efficiently deodorize the interior of the refrigerator. An adsorbent that can be used as a deodorizing material that allows for effective use of space in freezers or display stands without sacrificing space for food, etc., and as an insect repellent and mold repellent when storing clothing for long periods of time. The purpose is to provide materials and manufacturing methods.

Can be installed. In addition, an adsorbent attached to a sheet material adsorbs odors such as ethylene gas, ammonia gas, or decomposition gas of fish and livestock meat generated from food, and pineapple juice is added to the adsorbent and fermented to produce the adsorbent. The pineapple enzyme that is retained in the pineapple enzyme converts the adsorbed gas into amino acids that are useful for food, thereby suppressing the deterioration and promotion of spoilage, maintaining the freshness of food, and preventing the occurrence of bad odors that accompany food spoilage. This makes it possible to more reliably deodorize the inside of the refrigerator. In addition, when storing clothing for a long period of time in a drawer, costume case, etc., inserting the absorbent material between the clothing cotton prevents mildew from forming on the clothing, and also applies insect repellent to the clothing. It can also prevent odor from building up. To produce the adsorption material, pineapple juice is added to ore or activated carbon granules or granules, fermented, dispersed in water to form a suspension, and the suspension is used to form porous materials. The adsorbent material is produced by impregnating a sheet material with the above-mentioned material and drying it to remove moisture from the sheet material, and adhering the powder or granules to the sheet material as an adsorbent.

[Details of the invention]

The present invention provides that the pineapple enzyme converts ethylene gas, ammonia gas, fish and meat decomposition gas, etc. generated from foods into amino acids useful for foods, and that the action of the pineapple enzyme can prevent the growth of mold such as white mold. This is based on the knowledge that by combining this pineapple enzyme with conventionally known adsorbents such as porous ore such as zeolite or activated carbon, it can not only adsorb gases generated from food but also By converting the adsorbed gas into amino acids useful for food using pineapple enzymes, we can suppress the acceleration of food spoilage, thereby more reliably preventing the occurrence of bad odors in food storage spaces, and also storing clothes in drawers, etc. When stored for a long time in a clothing case or the like, it is possible to prevent the growth of mildew and the like, as well as to prevent the smell of insect repellents from attaching to the clothing.
