DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. Granules A according to the invention
As shown in FIG. 1, is formed in a granular shape and has a porous property. The granules function as a water activating material for activating water. At least the surface of the granular material A is coated with silver. That is, it is coated with silver. The size of the granular material A is about 3 mm.
From about 10 mm.

Next, a method for producing the granular material A having the above configuration will be described. Here, an example using barley stone as the granular material will be described. Here, the components of the barley stone are as shown in Table 1.

[0014]

[Table 1]

First, a rough barley stone is crushed (FIG. 3, S
10). In other words, rough barley stone is about 3 mm to about 10 m
Grind to a diameter of about m. Thus, by pulverizing to a certain diameter, the surface area of the granular material A can be increased, and the extraction ability and antibacterial ability of the mineral can be enhanced.
Next, the barley stone formed to a predetermined diameter is washed and dried (FIG. 3, S11). Thus, dust, dust, and the like attached to the barley stone are removed.

Next, the washed and dried barley stone is immersed in a silver-containing solution (FIG. 3, S12). This silver-containing solution is
Specifically, a sugar mixture and a polyhydric alcohol as a binder are added to silver powder of 5 to 50 microns to form a paste-like mixture. Specific examples of the sugar chains include starch, and examples of the high molecular weight polyhydric alcohols include methyl cellulose and ethyl cellulose. The mixing ratio of the binder is about 5 to 20% by weight with respect to the silver powder. This mixture is then added to water to produce a silver-containing solution. The mixing ratio of the above mixture is about 1 to 15% by weight. The barley stone is immersed in the silver-containing solution thus generated. This dipping process causes silver to adhere to the barley stone.

Next, the barley stone immersed in the silver-containing solution is fired at such a high temperature that silver is melted (FIG. 3, S13).
By this baking process, silver adhered to the surface and the holes is fixed,
Fix it. In addition, the binder is 200 degrees Celsius to 30 degrees Celsius.
Since it burns at 0 degrees, it does not remain in the granular material. As described above, the granular material A is formed. Note that, in the above description, barley stone is immersed in the silver-containing solution. However, the silver-containing solution may be sprayed from one side of the barite stone like a shower, and then fired.
In this way, a surface on which silver is not adhered is formed on the barley stone, and the extraction ability of the mineral component does not decrease.

The granular material A produced as described above has various uses, and can be used mainly for activating water. In other words, since the granular material A is composed of barley stone, when immersed in water, minerals are extracted and a bacteriostatic effect is obtained. Provides an antimicrobial action.
That is, an antibacterial effect is obtained by elution of silver ions and the like. Further, since the granular material A is formed porous, impurities and dust can be adsorbed.

Next, a description will be given of an experimental result of the granular material generated as described above. First, the contents of the first experiment will be described. In the first experiment, an antibacterial test was conducted on barley rice having antibacterial properties. For the test, Escherichia coli (Escherichia coli) I was used as a strain.
FO 12734 (hereinafter referred to as E. coli);
tapylococcus aureus (Staphylococcus aureus) (hereinafter referred to as S. aureus) was used. In addition, as a test method, Escherichia coli and Staphylococcus aureus were suspended in a phosphate buffer (pH 7.0) containing 0.2% of TWEEN80 according to the shake flask method to reduce the number of bacteria to about 1.0 ×. It was adjusted to 10 ⁴ / ml. Add 50 ml (milliliter) of this bacterial solution per 10 g of sample, and add
Horizontal shaking culture was performed at 0 ° C. for 24 hours. In addition, the number of viable bacteria in the culture solution was measured by a pour plate method using an SCDLP medium. Table 2 shows the results.

[0020]

[Table 2]

From Table 2, it was found that 4.0 × 10 ⁴ cells / ml existed at the start. E. coli (E. coli) is less than 10 cells / ml after 24 hours.
aureus (Staphylococcus aureus) was present at 1.1 × 10 ⁴ cells / ml at the start, but less than 10 cells / ml after 24 hours. That is,
From this, it can be seen that there is a sterilization rate of 99.9% or more, and thus it can be said that excellent antibacterial properties are exhibited.

Next, the contents of the second experiment will be described.
In this experiment, E. coli (serotype O157: H
7) The inoculated bacterial solution is used as a first test solution, and the granular material as a specimen is immersed in 1 liter of purified water for 1 hour, and then inoculated with a bacterial solution of Escherichia coli (serotype O157: H7). The first test solution and the second test solution were used as a second test solution, and the presence or absence of surviving bacteria in each of the first test solution and the second test solution was checked with time while stirring at room temperature.

The test method will be described more specifically. As the test strain, Escherichis col
i AATCC 43888 (E. coli, serotype O15
7: H7, a non-verotoxin-producing strain) was used, and as a test medium, a normal agar medium was used as an NA medium, and a normal broth containing 0.2% meat extract was used as an NB medium. Further, as a method of preparing a bacterial solution, a test strain pre-cultured in an NA medium at 37 ± 1 ° C. for 16 to 24 hours was used.
The cells were again inoculated into the medium and cultured at 37 ± 1 ° C. for 16 to 20 hours. The cells were uniformly dispersed in purified water, and the number of cells per ml was adjusted to 10 ⁸ . As a test operation, a test solution was prepared by inoculating 0.5 ml of a bacterial solution immediately after adding 100 g of a sample to 1 L (liter) of purified water and immersing for 1 hour. This was allowed to act while stirring at room temperature, and 0.5 ml, 1 hour, 2 hours and 5 hours later, 1 ml was inoculated and cultured in an NA medium (cultured at 37 ° C. for 2 days) to confirm the presence or absence of growth. Table 3 shows the results.
