Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing antibacterial substances.

[0002]

2. Description of the Related Art In recent years, interest in environmental hygiene and food hygiene has increased, and various household products and the like have been developed in response to these demands.

Among these household products, cookware, which is a cooking product, is used every day, and is also used to directly process food that enters the mouth of a person, so always pay attention to hygiene. It is a very important thing that needs to be paid.

[0004] Conventionally, wooden bowls have been widely used, and when wooden bowls are used to cut food,
Due to the softness of the wood, the kitchen knife cuts into the bowl for a good sharpness and excellent usability, while the gentleness of the knife against the kitchen knife makes the knife longer and lasts longer, etc. Have the advantages of.

On the other hand, since various types of bilge are processed and are always used in a state of containing moisture, various bacteria are easily proliferated, but the wooden porridge is hygroscopic. However, since it is soft and easily scratched as described above, there is a problem that it easily becomes a hotbed for breeding of various bacteria.

For this reason, conventionally, when using a wooden bowl, methods such as always washing well to keep it clean, or immersing it in an aqueous solution of a sterilizing agent for sterilization have been adopted.

[0007] In recent years, instead of the above-mentioned wooden bowls, there have been developed bowls having a constitution in which materials such as resin and ceramics which are not easily scratched or stainable are used, or those materials are coated with other materials. In addition, a technique for producing an antibacterial and durable bag has been developed by a method of mixing an antibacterial substance into the material such as the resin or ceramic.

[0008]

However, in the above-mentioned conventional antibacterial bowl using resin or ceramic, when the object is cut with a kitchen knife, the material of the bowl is hard and the sharpness is poor.
In addition, the feeling of use is not so good, and the hardness of the knife is short, the sharpness of the knife is short, the number of times the knife is sharpened is increased, and the life of the knife is shortened.

The present invention has been made in view of the above-mentioned conventional problems, and has all the advantages of the conventional wooden sack, and has a hygienic antibacterial property capable of sustaining the antibacterial action. The purpose is to provide.

[0010]

The present invention is characterized in that an aqueous silver oxide solution prepared by dissolving silver oxide in ammonia water is sufficiently impregnated into a wooden bowl and then dried to wipe away the silver oxide on the surface. The present invention relates to a method for producing an antibacterial effect.

[0011]

In the present invention, a silver oxide aqueous solution is prepared by the silver oxide aqueous solution producing step I in which silver oxide is dissolved in ammonia water, and a wooden bowl is formed by a wooden bowl forming step II in the same manner as in the conventional case. The wooden bowl is soaked in the silver oxide aqueous solution or the silver oxide aqueous solution is sprayed or applied to the wooden bowl to allow the silver oxide aqueous solution to sufficiently penetrate into the wooden bowl, and then Drying / wiping step IV in which the bag is naturally dried or dried by a dryer and the silver oxide adhering to the surface of the dried wood bag is wiped off.
To obtain antibacterial properties.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. A silver oxide aqueous solution 3 is prepared by a silver oxide aqueous solution manufacturing step I in which silver oxide 1 is dissolved in ammonia water 2 and is stored in a container 4.

Further, as in the conventional case, a wooden bowl 5 is formed from a wooden board or the like in a wooden bowl forming step II.

Subsequently, the wooden oxide 5 is soaked in the silver oxide aqueous solution 3 or the silver oxide aqueous solution 3 is sprayed or applied to the wooden oxide 5 by a permeation step III so that the silver oxide aqueous solution 3 is added to the wooden oxide 5. Sufficiently penetrate 5

An antibacterial effect 6 is obtained by carrying out a drying / wiping step IV in which the wooden effect 5 is dried naturally or by a drier, and silver oxide adhering to the surface of the dried wooden effect 5 is wiped off. .

Example 1

An aqueous silver oxide solution prepared by dissolving 1 g of silver oxide in 2 liters of 10% aqueous ammonia was prepared in a shallow container, and the length of the solution was 50 cm, the width was 25 cm, and the thickness was 4 cm.
Immerse a wooden bowl processed into cm for 24 hours, then remove the wooden bowl from the silver oxide aqueous solution, wipe off the silver oxide aqueous solution, and further dry in a drying room at 25 ° C for 24 hours, and then on the surface of the wooden bowl. The attached silver oxide was wiped off to make it antibacterial.

In order to check the permeation state of the aqueous silver oxide solution at the time of producing the above-mentioned antibacterial odor, a wooden enamel immersed in the aqueous silver oxide solution for 24 hours was cracked to find that the aqueous silver oxide solution had completely penetrated to the core. .

Further, after using the above-mentioned antibacterial bacillus, when the microbes were inspected for reproduction of microbes, the propagation of microbes was extremely less than that of the normally used wood.
It was confirmed that there was a sufficient effect of suppressing the propagation of various bacteria.

Further, the above-mentioned antibacterial bag can form a smooth new surface by cutting the surface when the surface has irregularities due to long-term use. The antibacterial action of the retained silver oxide can be sustained.

The present invention is not limited to the above-mentioned embodiments, and the concentration of ammonia water, the concentration of silver oxide in a silver oxide aqueous solution, etc. can be arbitrarily selected, and the scope of the present invention is not deviated. Of course, various changes can be made within.

[0023]

According to the method for producing an antibacterial effect of the present invention, a hygienic antibacterial effect having all of the excellent features of a conventional wooden effect and capable of sustaining an antibacterial effect. It is possible to exert an excellent effect that can provide.
