DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antibacterial cutting board package containing chitin and chitosan, which can prevent the growth of bacteria and the adhesion of various bacteria to the cutting board by merely covering the cutting board.

[0002]

2. Description of the Related Art Cutting boards are susceptible to soiling due to processing of various foods such as meat, seafood, vegetables, and the like. In addition, since the surface of the cutting knife is innumerably scratched, juices from the foods are contained in the wounds. Is easily taken in, causing germs to multiply, causing putrefactive odor and causing food poisoning. Frequent cleaning and hot water disinfection are necessary to control the growth of various bacteria, and they must be regularly immersed in a bleach solution such as hypochlorite or percarbonate for a long time, It is necessary to perform sterilization by spraying, applying, or the like of such a chemical. However, since the cutting board has countless scratches on its surface, it is difficult for bleaching agents and germicides to penetrate into the inside of the scratches, sterilization is not performed sufficiently, and depending on the storage location, pests such as cockroaches and flies There is a possibility that the germs may adhere to the surface of the cutting board and the germs may grow on the surface of the cutting board. Therefore, cutting boards made by mixing metal salts such as silver chloride and copper chloride into synthetic resins, etc., and in recent years made of synthetic resins mixed with zeolite containing an antibacterial agent, as those that imparted bactericidal and antibacterial properties to cutting boards. Various cutting boards have been studied. For example, Japanese Patent Application Laid-Open No. Hei 3-195522
JP-A-5-176848 and JP-A-5-176848 disclose an antibacterial cutting board in which zeolite containing an antibacterial agent is mixed in low-density polyethylene and disposed on the surface layer or side surface of the cutting board.

[0003]

However, the above-mentioned conventional antibacterial cutting board has the following problems. (1) Even if a metal salt such as silver chloride or copper chloride is contained, only the metal salt can exhibit antibacterial properties, and harmful metal ions gradually elute over a long period of use. There is a problem that it may adhere to the skin or cause skin irritation due to metal allergy. Also,
The antibacterial cutting board containing the zeolite disclosed in JP-A No. and JP-A No. H-2002 has the following problems. (2) Since zeolite is mixed with low-density polyethylene, the surface of the cutting board is liable to be cracked or chipped over a long period of use, and the surface is hardened by zeolite, which places a burden on wrists and the like when processing foodstuffs. In addition to this, there is a problem that wear and dulling of the blade of the kitchen knife tend to be quick. (3) When an organic compound is used as an antibacterial agent, there is a problem in that a toxic gas is generated when incinerated, and there is a risk that the surrounding environment will be polluted when disposed in a landfill or the like. (4) There is a problem that it is difficult to apply the method to a wooden chopping board having many lovers than before. As described above, it has been found that imparting bactericidal or antibacterial properties to the cutting board itself has many problems. Then, as a result of intensive studies, the present inventors have found that by wrapping the cutting board with an antibacterial cloth, it is possible to suppress the adhesion of various bacteria and the propagation of various bacteria on the cutting board. As a conventional cloth having antibacterial properties, a cloth containing a synthetic antibacterial agent or the like in a cloth is known. However, it has been found that the use of the cloth for cutting board packaging has the following problems. (5) A fabric impregnated with an antibacterial agent is not suitable for wrapping a cutting board for handling foodstuffs. Also, repeated washing will cause the antibacterial agent and the like to be washed away, so the effect will be less persistent,
In addition, there is a problem that the disposal may cause environmental pollution. (6) On the other hand, various natural materials having antibacterial properties are known. Natural materials considered to have relatively high safety to the human body and the environment include spices such as pepper, wasabi, garlic, bamboo, mugwort, Although plant components such as hinoki are known, most of these natural materials show antibacterial properties due to the irritant and fragrant essential oil components. There was a problem that it was difficult to apply. (7) Further, when contained in a fabric, each antibacterial essential oil component volatilizes to reduce the antibacterial action, and has a problem that the duration of the effect is extremely short because it is easy to flow out by washing. ing.

[0004] The present invention solves the above-mentioned conventional problems, and the cockroaches can be obtained by simply wrapping or covering the cutting board.
Attachment of germs from outside due to contact with flies, rats, etc.,
Antibacterial cutting board which can sterilize and prevent the growth of various bacteria on the surface of the cutting board, and is extremely safe because of its extremely low skin irritation, toxicity and environmental pollution. The purpose is to provide a package.

[0005]

In order to solve the above-mentioned conventional problems, the antibacterial cutting board package of the present invention has a structure formed of a cloth containing chitin / chitosan in fibers. With this configuration, chitin and chitosan have antibacterial properties, so wrapping the cutting board after cleaning or sterilization or simply covering it on the cutting board prevents adhesion of various germs from the outside and sterilization on the entire cutting board surface. And the growth of various bacteria can be prevented. In addition, a highly safe antibacterial cutting board package that does not cause environmental pollution even when disposed of, with little risk of skin irritation or allergy, can be obtained.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The antibacterial cutting board package according to the first aspect of the present invention has a structure formed of a cloth containing chitin / chitosan in fibers. With this configuration,
Chitin and chitosan have excellent antibacterial properties against food poisoning bacteria such as Staphylococcus aureus and Escherichia coli, Klebsiella pneumoniae, Trichophyton, etc. Simply wrapping in a cutting board package or putting on a cutting board has the effect of preventing the attachment of foreign bacteria from cockroaches, flies, rats and the like and the growth of bacteria on the cutting board surface. Chitin and chitosan are natural ingredients used in foods and pharmaceuticals as described in the Ministry of Health and Welfare's "List of Food Additives Other than Chemical Synthetic Products". It has the effect of being extremely safe because it hardly shows any toxicity or allergy. Furthermore, chitin and chitosan have almost no toxic gas when burned, and have an effect that they do not cause environmental pollution due to their excellent biodegradability even when they are disposed of by landfilling. Further, it can be used regardless of whether the material of the cutting board is made of wood or synthetic resin, and has an effect that application is extremely easy.

Here, as the fabric containing chitin / chitosan, a woven or non-woven fabric is used. As a fiber as a raw material of the fabric, artificial fibers such as rayon, acetate, cupra, acrylic, nylon, polyester, vinylon, and polypropylene, and natural fibers such as cotton and hemp are used. In particular, rayon, acetate, cotton, hemp, and the like are preferably used because of their excellent moisture retention and excellent touch. Kitchen·
As a method of including chitosan in a fabric, a method of applying chitin / chitosan with a binder to a fiber or a fabric or kneading the fiber or the fabric is used. Further, a fiber obtained by twisting the fiber of the raw material of the cloth and the fibrous chitin / chitosan may be used as the cloth. Further, when the fabric is formed of rayon fiber, a method of directly converting chitin / chitosan into viscose, uniformly dissolving and fusing with viscose prepared from cellulose at an arbitrary ratio, and extruding into diluted sulfuric acid to form a fiber is particularly preferable. It is preferably used. As a result, chitin / chitosan becomes fibrous and increases in strength, and since it is continuous in the fiber, the surface area is increased and an extremely high antibacterial property can be exhibited. Furthermore, chitin / chitosan has low water solubility and is firmly bonded to the fiber by the above-mentioned manufacturing method, so that it is hard to be washed away even by washing, etc., and can keep a clean state by repeating washing, and has antibacterial properties for a long time Can be maintained. In addition, since viscose prepared from chitin / chitosan and viscose prepared from cellulose can be mixed into an arbitrary ratio to form a fiber, the chitin / chitosan content according to the strength and antibacterial properties is required. Fibers and fabrics can be prepared.

[0008] The antibacterial cutting board package according to the second aspect of the present invention has a structure in which the antibacterial cutting board packaging body is formed in a bag shape in the first aspect.
According to this configuration, in addition to the function described in the first aspect, an excellent antibacterial property can be obtained by an extremely simple operation of putting the cutting board into a bag-shaped antibacterial cutting board package.

The antibacterial cutting board package according to a third aspect of the present invention is the package according to the first or second aspect, wherein the chitin / chitosan is contained in the fiber in an amount of 30 to 100% by weight. Have. With this configuration, it is possible to obtain excellent antibacterial properties against a wide range of germs and to obtain a cutting board package having high strength and excellent durability. Here, chitin and chitosan are 30
When the amount is less than the weight%, it depends on the type and thickness of the fiber, but it is difficult to obtain sufficient antibacterial property, which is not preferable.
