Hereinafter, embodiments for carrying out the present invention (hereinafter, embodiments of the present invention) will be described in detail. The present invention is not limited to the following embodiments, and can be variously modified and implemented within the scope of the gist thereof. In addition, the drawings used are for explaining the present embodiment and do not represent the actual size.
Hereinafter, the magnesium hydroxide suspension and the like to which the present embodiment is applied will be described with reference to the drawings.

[First Embodiment]
First, the first embodiment of the cooking utensil will be described. In the first embodiment, at least a part of the cooking utensil uses a member made of a metal material containing magnesium as a main component.

1 (a) to 1 (b) are views showing a first example of the cooking utensil of the present embodiment.
The cooking utensil of this embodiment is used in contact with water. This water is, for example, water contained in the cooking object itself or water attached when the cooking object is washed.
The illustrated cooking utensil is a cutting board 10. That is, the cutting board 10 is a mounting table for processing by cutting the cooking object or the like using another cooking utensil such as a kitchen knife. The cooking target is a cooking target or a cooked dish, and is not particularly limited as long as it is cooked using the cutting board 10. Examples of cooking targets include meat, fish, vegetables, fruits, and mixtures thereof.

Of these, FIG. 1A is a perspective view of the cutting board 10, and FIG. 1B is a cross-sectional view taken along the line Ib-Ib of the cutting board 10.
As shown, the cutting board 10 includes a base 11 and a member 12.
The substrate 11 is, so to speak, the main body of the cutting board 10. The substrate 11 is made of the material used for ordinary cutting boards. Here, the substrate 11 is plate-shaped and is made of, for example, a material such as wood or resin.
The member 12 is a member containing a metal material containing magnesium as a main component, and here, has a plate shape. Here, the "metal material containing magnesium as a main component" is a metal material containing 50% by weight or more of magnesium. However, magnesium is preferably contained in an amount of 90% or more by weight, more preferably 99% or more, and particularly preferably 99.9% or more. Further, as the metal material, magnesium and another metal may be an alloy, and magnesium and a plurality of metals may be simply bonded instead of the alloy.
Examples of components that may be contained as components other than magnesium alone include iron, aluminum, zinc, manganese, nickel, calcium, silicon, titanium, and copper.

By providing the member 12, a sterilizing action is generated on the cutting board 10. That is, for example, the water contained in the cooking object itself or the water attached when the cooking object is washed reacts with magnesium. At this time, the following reaction (1) occurs, and hydrogen (H ₂ ) and magnesium hydroxide (Mg (OH) ₂ ) are produced in water.

Mg + 2H ₂ O → H ₂ + Mg (OH) ₂ … (1)

Water containing magnesium hydroxide is alkaline. The pH of water at this time is, for example, 8 to 10. Then, as the pH rises, a sterilizing action occurs. In addition, the increase in pH causes a deodorant effect. In addition, −OH ⁻ (hydroxy group, hydroxide group) is generated to produce an oxidative sterilization effect. That is, since the fungi that are the basis of the odor can be reduced by the bactericidal action, the deodorizing action also occurs.

Further, in the reaction of the formula (1), hydrogen is generated. Then, the action of hydrogen increases the penetrating power of water, and even if the substrate 11 is scratched, for example, water easily penetrates into the scratch. As a result, the sterilizing action and the deodorizing action tend to increase.

The base 11 and the member 12 are joined. In the illustrated example, the three rectangular members 12 are joined to the substrate 11 so as to be substantially parallel to each other. In the present embodiment, the groove portion 11a is formed in the substrate 11, and the member 12 is embedded in the groove portion 11a. The form of joining is not particularly limited, and examples thereof include fitting, adhesive screwing, and bolting. However, it is preferable that the member 12 is replaceable. As a result, the substrate 11 and the member 12 can be cleaned separately. Further, even if the member 12 is worn or damaged, it can be replaced.
Further, it is preferable that the member 12 is provided at a position in the substrate 11 that comes into contact with the cooking object. In the illustrated example, the member 12 is located on the upper surface of the cutting board 10 and is provided at a position where it comes into contact with the cooking object. As a result, the cooking object and the member 12 come into contact with each other, and the sterilizing action also occurs on the cooking object. In addition, the odor of the cooking object itself can be suppressed, and the odor transfer from the cutting board 10 to the cooking object can be suppressed.

2 (a) to 2 (b) are views showing another example of the cutting board 10 of the present embodiment.
Of these, FIG. 2A shows a case where the member 12 is provided on the entire upper surface of the cutting board 10. In this case, the upper surface of the base 11 is completely covered with the member 12, and the base 11 and the member 12 are laminated.
Further, FIG. 2B shows a case where the member 12 is provided at the center of the upper surface of the cutting board 10. In this case, there is only one member 12, and it is provided at the center of the cutting board 10 where cooking is mainly performed.
Also in the cases of FIGS. 2A to 2B, the member 12 is provided at a position in the substrate 11 where it comes into contact with the cooking object. That is, the member 12 is provided on the upper surface of the cutting board 10, which is a portion that comes into contact with the cooking object.

FIG. 3 is a diagram showing a second example of the cooking utensil of the present embodiment.
The illustrated cooking utensil is a tray 20. The tray 20 is a cooking utensil having an opening on the upper surface and an accommodating portion for storing a cooking object inside.
The tray 20 shown in FIG. 3 is a case where the tray 20 is made of a member 22 made of a metal material containing magnesium as a main component. The tray 20 can be made, for example, by pressing a plate made of a metal material having this composition.

4 (a) to 4 (c) are views showing another example of the tray 20 of the present embodiment.
4 (a) to 4 (c) show the case where the metal material is joined to the inner wall of the substrate 21.
Of these, FIG. 4A shows a case where the member 22 is provided on the inner bottom surface of the base 21 of the tray 20. Like the member 12, the member 22 is made of a metal material containing magnesium as a main component. In this case, the inner bottom surface of the substrate 21 is covered with the member 22. On the other hand, the side surface of the base 21 is not provided with the member 22, and the base 21 is exposed. The substrate 21 is made of, for example, stainless steel, resin, wood, or the like. A tray 20 is formed by joining a rectangular and plate-shaped member 22 as shown to the inner bottom surface of the substrate 21.
Further, FIG. 4B shows a case where the member 22 has a net shape. That is, the member 22 is a mesh. In this case, the member 22 is provided on the inner bottom surface of the substrate 21. Then, a member 22 which is a rectangular net body as shown in the figure is joined to the inner bottom surface of the substrate 21 to form a tray 20.
4 (a) to 4 (b) show the tray 20 having a shallow bottom, but FIG. 4 (c) shows the case where the tray 20 has a deep bottom. The illustrated tray 20 is also called a hotel bread. FIG. 4C shows a case where the member 22 is provided on the side surface of the base 21 of the tray 20. In this case, the case where four rectangular members 22 are provided on each of the four side surfaces of the base 21 of the tray 20 is shown.

Also in the examples shown in FIGS. 3 and 4, the member 22 is provided at a position in the substrate 21 where it comes into contact with the cooking object. That is, the member 22 is provided so as to be located at least on the bottom surface or the side surface inside the tray 20. As a result, the above-mentioned cooking object has a sterilizing effect and an odor suppression.

Further, when vegetables or the like are put in the tray 20, freshness can be expected to be maintained. That is, in the state of being put in the tray 20, the vegetables cannot absorb nutrients from the roots, but photosynthesis is possible. Therefore, by supplying a small amount of magnesium from the member 22, it becomes easy to maintain the freshness. Therefore, it is possible to provide fresher vegetables and the like.

Further, by using the base 21 of the tray 20 as a material containing iron as a main component such as stainless steel, the reaction of the above-mentioned formula (1) is likely to occur, and these effects are promoted. That is, by using a material containing iron as a main component such as stainless steel, a local battery is formed between the member 22 containing magnesium and the inner wall of the substrate 21 containing iron, and the redox reaction is caused by the electrode potential difference thereof. It is generated, and magnesium and water are easily reacted.

FIG. 5 is a diagram showing still another example of the cooking utensil of the present embodiment.
The illustrated cooking utensils are three types: a pot 30, a ladle 40, and an insole 50. Then, the pot 30 heats or accommodates the cooking object inside. Further, the ladle 40 is used, for example, to scoop and stir the cooking object placed in the pot 30. Further, the insole 50 is arranged on the bottom surface of the pot 30, for example, and is used to prevent these scorching.

Of these, the pot 30 shows a case where the member 32 is provided on the inner bottom surface of the base 31 of the pot 30. Further, the ladle 40 shows a case where the member 42 is provided on the inner bottom surface of the base 41 of the ladle 40. Further, the insole 50 shows a case where the member 52 is provided on the inner bottom surface of the base 51 of the insole 50. The members 32, 42, and 52 are all made of a metal material containing magnesium as a main component, similarly to the member 12. In this case as well, the members 32, 42, and 52 are provided at locations where they come into contact with the cooking object. That is, the members 32, 42, and 52 are provided so as to be located at least on the bottom surface inside the pot 30, the ladle 40, and the insole 50. As a result, the above-mentioned cooking object also has a sterilizing action and an odor suppression.
In the above-mentioned example, the insole 50 is shown, but this may be a sheet shape and may be an insole sheet.

[Second Embodiment]
Next, a second embodiment of the cooking utensil will be described. In the second embodiment, the base of the cooking utensil is mixed with magnesium hydroxide particles or impregnated with an aqueous solution of magnesium hydroxide.

Here, as a first example of the second embodiment, a case where the base 11 of the cutting board 10 contains magnesium hydroxide particles will be described.
In this case, the substrate 11 is made of a material capable of mixing magnesium hydroxide particles such as resin. For magnesium particles, for example, a plurality of pellets containing magnesium are agitated while being in contact with each other in water to polish the surface of the plurality of pellets, and the magnesium hydroxide particles are separated from the polished liquid. Can be obtained at. That is, as shown in the above equation (1), magnesium contained in the pellet reacts with water, and as a result, magnesium particles are generated. Then, the magnesium particles are separated by precipitation or the like and dried.

First, the resin and magnesium hydroxide particles used as the material of the substrate 11 are prepared (step 101: preparation step). In the preparation step, preparations may be made by producing particles of resin or magnesium hydroxide, or preparations may be made by purchasing these. The resin prepared here is, for example, a thermoplastic resin.
Next, the resin is heated and plasticized (step 102: heating step). Then, the magnesium hydroxide particles are added to the plasticized resin and mixed (step 103: mixing step). The mixing step can be performed by using, for example, a kneader or the like.
Then, a resin mixed with magnesium hydroxide particles is molded to form a substrate 11 of the cutting board 10 (step 104: molding step). The molding step can be performed, for example, by using an injection machine to inject a resin mixed with magnesium hydroxide particles into a mold for forming the substrate 11.
Further, the substrate 11 molded by the molding step and the member 12 made of a metal material containing magnesium as a main component are joined (step 105: joining step).

Although the case where magnesium hydroxide particles are mixed with the substrate 11 of the cutting board 10 has been described here, the present invention is not limited to this, and any substrate capable of mixing magnesium hydroxide particles is not limited to this. Can be applied. Therefore, for example, it can be applied even when a resin is used as the base 21 of the tray 20.

Next, as a second example of the second embodiment, a case where the substrate 11 of the cutting board 10 is impregnated with the reaction solution obtained by reacting magnesium and water will be described.
In this case, the substrate 11 is made of a material such as wood that can be impregnated with the reaction solution. In the reaction solution, for example, a plurality of pellets containing magnesium are agitated while being in contact with each other in water to polish the surface of the plurality of pellets, and agglomerates composed of magnesium hydroxide particles are obtained from the polished solution. It is the removed magnesium reaction solution. That is, as described above, magnesium contained in the pellets reacts with water, and as a result, magnesium particles are produced. Then, the magnesium particles are separated by precipitation or the like, and the supernatant liquid is used as this reaction liquid. The reaction solution is, for example, a saturated aqueous solution of magnesium hydroxide. Further, the water used for stirring a plurality of pellets containing magnesium in contact with each other in water may contain other components as long as it contains water.

FIG. 6B is a diagram showing a method for producing a cutting board 10 having a substrate 11 impregnated with a reaction solution.

Next, the substrate 11 is impregnated with the reaction solution (step 202: impregnation step). The impregnation step can be performed by impregnating the wood as the material of the substrate 11 with the reaction solution by applying pressure using a pressure impregnation device. At this time, heating may be performed.
Then, the substrate 11 impregnated with the reaction solution and the member 12 made of a metal material containing magnesium as a main component are joined (step 203: joining step).

Although the case where the substrate 11 of the cutting board 10 is impregnated with the reaction solution has been described here, the present invention is not limited to this case, and any substrate that can mix the reaction solution can be applied. be. Therefore, for example, it can be applied to the case where wood is used as the base 21 of the tray 20.
