Description

The present invention relates to a method for producing potable hydrogen water that can be filled into a PET bottle that hardly leaks hydrogen molecules from the PET bottle even when the PET bottle is filled.

In recent years, it has been found that hydrogen directly decomposes hydroxyl radical (.OH), which is a typical active oxygen in a living body, into stable water. Since then, hydrogen water has attracted attention. In Japan, alkali ion water conditioners or alkali ion (water) generators have been approved by the Ministry of Health at that time as medical devices over 40 years ago. However, until now, it has been impossible to find a clear answer as to what causes various medical effects in alkaline ionized water. However, hydrogen in alkali ion water recently generated by electrolysis is considered to be one of the main components. Until now, a lot of hydrogen water in PET bottles has been sold, but since hydrogen has the smallest molecule, it easily escapes from PET bottles, making it meaningless. For this reason, it was impossible for hydrogen water to be contained in an aluminum container such as an aluminum pouch, and it has become common knowledge in the industry that the aluminum does not last long if the aluminum is thin.

As described above, even when hydrogen water in which hydrogen gas is dissolved in water or hydrogen water generated by electrolyzing water is filled in a PET bottle, hydrogen molecules easily escape from the PET bottle. As disclosed in the following Patent Document 1, a means for generating hydrogen water by attaching a hydrogen generator filled with hydrogen generating particles in a bag to a cap of a bottle and bringing it into contact with water immediately before drinking is known. .

As described above, conventionally, even when hydrogen water is filled into a PET bottle, hydrogen molecules easily escape from the PET bottle, so the aluminum container must be filled. There was a problem of having to drink.

Moreover, although the thing of patent document 1 immerses a hydrogen generating body in water at the time of drinking and produces | generates hydrogen water, it is unknown how long hydrogen water is produced | generated, and it can drink immediately. There was a problem that it was not possible.

[First step]
In the first step of the present invention, a white turbid dispersion is prepared by mixing calcium carbonate (CaCO ₃ ), calcium hydroxide (Ca (OH) ₂ ), and magnesium oxide (MgO) with purified water. A mixed solution obtained by adding and mixing a phosphoric acid aqueous solution in which phosphoric acid (H ₃ PO ₄ ) and purified water are mixed to the solution is added to and mixed with a citric acid aqueous solution in which citric acid and purified water are mixed to form a colloid An acidic aqueous solution of

In producing the acidic aqueous solution, the mixing ratio (% by weight) of calcium carbonate, calcium hydroxide, magnesium oxide and purified water is preferably 0.5 to 3.0% by weight of calcium carbonate, water. It is recommended to use 5.0 to 10.0% by weight of calcium oxide, 0.5 to 3.0% by weight of magnesium oxide, and 84.0 to 94.0% by weight of purified water. -2.0 wt%, calcium hydroxide 7.0-9.0 wt%, calcium oxide 1.0-2.0 wt% and purified water 87.0-91.0 wt% are recommended . Then, the calcium carbonate, calcium hydroxide, magnesium oxide and purified water are mixed at the mixing ratio to prepare a cloudy dispersion.

It is recommended that the phosphoric acid aqueous solution mixed in the cloudy dispersion is preferably 35.0 to 55.0% by weight of phosphoric acid and 45.0 to 65.0% by weight of purified water, particularly preferably phosphorous. It is recommended that the acid be 40.0 to 50.0% by weight and purified water be 50.0 to 60.0% by weight.

Then, an aqueous phosphoric acid solution is mixed with the white dispersion of calcium carbonate, calcium hydroxide, magnesium oxide and purified water, and an aqueous citric acid solution is added to produce an acidic aqueous solution. The aqueous citric acid solution is preferably , Citric acid 5.0-13.0 wt% and purified water 87.0-95.0 wt% are recommended, and citric acid 8.0-11.0 wt% and purified water 89 are particularly preferable. It is recommended to produce as 0 to 92.0% by weight. This first step is a step for fixing hydrogen to the calcium-magnesium-phosphate-citrate complex and making it a transparent solution.

[Second step]
The second step in the present invention is a step of producing a mixed solution having a pH in the range of 5 to 8 by mixing the acidic aqueous solution and the alkaline aqueous solution produced in the first step. It is appropriate that the pH of the mixed solution is measured with a pH test paper from the viewpoint that an accurate pH can be measured without the influence of coexisting ions. In the solution system, measurement may not be possible with a normal pH meter using a glass electrode, and measurement with a pH test paper is appropriate. It is preferable from the viewpoint that the mixed solution manufactured in the second step has a pH in the range of 6.5 to 8 as a beverage.

The alkaline aqueous solution added and mixed with the acidic aqueous solution produced in the first step is obtained by mixing potassium hydroxide, sodium hydroxide and purified water, and the mixing ratio is preferably 3.0 to 7 potassium hydroxide. It is recommended to be 0.0 wt%, sodium hydroxide 2.0 to 6.0 wt% and purified water 87.0 to 95.0 wt%, particularly preferably potassium hydroxide 4.0 to 6.0. It is recommended that the content be 10% by weight, 3.0 to 5.0% by weight of sodium hydroxide, and 89.0 to 93.0% by weight of purified water.

[Third step]
The third step in the present invention is a step for obtaining a hydrogen water stock solution by electrolyzing the mixed solution produced in the second step. The electrolysis in the third step is performed by immersing the cathode and the anode in the mixed solution produced in the second step. As the cathode and the anode, inert electrodes may be used. For example, it is recommended to use platinum or carbon electrodes. The voltage of the cathode and the anode may be set to a value suitable for water electrolysis. The current can be appropriately set in consideration of the area of the electrode, the amount of solution, and the like. The electrolysis time can be appropriately set in consideration of the amount of solution, the amount of components in the solution, the hydrogen content after electrolysis, and the like.

The electrolysis in the third step is performed until the redox potential of the cathode water becomes −500 mV or less. By carrying out until the redox potential of the cathode water becomes −500 mV or less, a hydrogen water stock solution containing a predetermined amount of hydrogen content can be obtained.

The hydrogen content (concentration) of the hydrogen water stock solution obtained in the third step is measured using a commercially available measuring instrument, for example, KM2100DH (manufactured by Kyoei Denshi Laboratories). Can be measured quantitatively).

[Fourth process]
The hydrogen water stock solution produced in the third step has a relatively high concentration of hydrogen content and also has a poor taste due to its high concentration, and is not suitable for drinking. In the fourth step of the present invention, in order to be able to drink the hydrogen water stock solution, it is diluted 80 to 120 times with mineral water to have a hydrogen content in the range of 0.01 to 0.8 mg / l. This is a process for producing raw water.

If the hydrogen content does not fall within the range of 0.01 to 0.8 mg / l even if the hydrogen water stock solution is diluted 80 to 120 times with mineral water in the fourth step, electrolysis is performed again. The hydrogen content is in the range of 0.01 to 0.8 mg / l. The conditions of the voltage and current value in the second electrolysis can be the same as those in the electrolysis in the fourth step, but the time can be short, for example, 1 to 10 minutes. Moreover, in order to make it drinkable, the heat sterilization (for example, 85 degreeC x 40 minutes) prescribed | regulated by the sanitary law after the said dilution can also be performed, and the said electrolysis is performed before or after heat sterilization. it can. The potable hydrogen water obtained by the production method of the present invention also has a feature that the hydrogen content does not greatly decrease even when the heat sterilization is performed.

Next, an example of a test for producing potable hydrogen water using the method for producing potable hydrogen water that can be filled in a PET bottle according to Example 1 of the present invention will be described in detail. The following operations were all performed at room temperature.

A cloudy dispersion liquid comprising the components shown in the following (A) was prepared. To this dispersion, a phosphoric acid (H ₃ PO ₄ ) aqueous solution composed of the following component (B) was mixed and reacted. When mixed, the solution temporarily became transparent, but finally became cloudy, and a mixed solution in which very fine particles were dispersed (1000 g) was obtained. Furthermore, when a citric acid aqueous solution composed of the following component (C) was added to the mixed solution of (A) and (B), the cloudy liquid became a transparent colloidal solution. The total amount of colloidal liquid (A + B + C) was 5000 g (hereinafter referred to as “one liquid”). In addition, the weight of each raw material which manufactures the cloudy dispersion liquid of the following (A)-(D), phosphoric acid aqueous solution, citric acid aqueous solution, and alkaline aqueous solution is in the range as described in the said preferable mixture ratio.

(A) 8.5 g of white turbid dispersion CaCO ₃
Ca (OH) ₂ 40.0 g
MgO 8.5g
443.0 g of purified water
Subtotal 500g

(B) 220.0 g of phosphoric acid aqueous solution H ₃ PO ₄
Purified water 280.0g
Subtotal 500g

(C) Citric acid aqueous solution Citric acid 390.0 g
3610.0 g of purified water
Subtotal 4000g

Next, when a small amount of the one liquid is added to an alkaline aqueous solution composed of the components shown in the following (D), it becomes a cloudy dispersion and immediately becomes a transparent liquid. Subsequently, the solution 1 was further added until the pH reached 6.5 (pH test paper). As a result, when 5000 g of 1 liquid was added, it became pH 6.5 (pH test paper). The total amount of the obtained aqueous solution (hereinafter referred to as “two liquids”) was 10,000 g.

(D) Alkaline aqueous solution KOH 200.0 g
NaOH 180.0g
4620.0 g of purified water
Subtotal 5000g

Next, a direct current of 10 A was applied to the two liquids at 5 to 15 V, and electrolysis was performed for 100 minutes.

In the electrolysis, it is presumed that H ₂ generated at the cathode sorbs on the colloidal particles present in the solution and covers the entire particles. Further, protons (H ⁺ ) generated at the anode are adsorbed on the colloidal particles, and the entire colloidal particles have a positive charge, while negative groups of citric acid are attached to form a so-called electric double layer. Inferred. Dispersion media hydroxide ion (OH ^-) and is, in effect by interaction with the electric double layer and the colloidal particles having a positive charge, is presumed to be covered by the hydroxide ion is a negative ions generated at the cathode The Therefore, a transparent hydrogen water stock solution without precipitation was obtained.

The hydrogen content of the aqueous solution (2 liquids) before the electrolysis and the hydrogen content in the hydrogen water stock solution after the electrolysis are KM2100DH manufactured by Kyoei Denshi Laboratories (method is a diaphragm-type polaro method, and dissolved hydrogen can be measured quantitatively. As a result, the hydrogen content before electrolysis was 0.02 mg / l, whereas the hydrogen content after electrolysis was 0.8 mg / l. In addition, the hydrogen content was almost saturated after 100 minutes of energization.

And the hydrogen water stock solution after electrolysis (dissolved hydrogen amount 0.7 mg / l) was diluted 100 times with mineral water to obtain drinking hydrogen water. The amount of dissolved hydrogen in 100-fold diluted hydrogen water obtained was 0.4 mg / l.

A graph showing changes over time in the amount of dissolved hydrogen in potable hydrogen water obtained by diluting the hydrogen water stock solution with mineral water sampled at Okunagara River in Gifu Prefecture 100 times, 200 times and 300 times As shown in FIG. In the figure, the indications “100A” and “100B” indicate that two 500 ml PET bottles filled with 100-fold diluted hydrogen water were measured, respectively, “200A” and “200B”. The same applies to “300A” and “300B”. The measurement of these dissolved hydrogen amounts is carried out every day by putting hydrogen water into a measurement cell of a dissolved hydrogen meter manufactured by Kyoei Denshi Laboratory and stirring with a magnetic stirrer for about 10 to 15 minutes. After the measurement, each of the measured drinking hydrogen water was returned to the plastic bottle. And it measured for 9 days by repeating the same operation.

FIG. 1 shows a dilute mineral water sampled at the Okunagara River on May 19, 2010 at the dilution ratio described above, in the hydrogen water stock solution produced at the mixing ratio shown in the test example on February 12, 2010. The change in the amount of dissolved hydrogen was measured on a daily basis for the drinking hydrogen water immediately filled in the PET bottle. In FIG. 1, the amount of dissolved hydrogen initially increases and then decreases after peaking when the amount of generated hydrogen is initially larger than the amount of scattered hydrogen after passing through the PET bottle, and the amount of generated hydrogen is equal to the amount of scattered. On the contrary, it is presumed that the amount of scattering will be larger than the amount of dissolved hydrogen generated and will decrease.

From the measurement results shown in FIG. 1, the hydrogen generation amount is almost 0 for each drinking hydrogen water from the day (May 19) to the second day (May 21) after filling the bottled water with the drinking water. It was close to. However, on May 22nd on the third day, the amount of hydrogen generated by the 100-fold dilution of drinking hydrogen water increased abruptly. The other 200-fold and 300-fold diluted hydrogen water produced a slight increase in hydrogen generation but did not increase much. And the amount of dissolved hydrogen gradually decreased after peaking on May 22, and the 200-fold diluted drinking hydrogen water became zero from May 26 to 27, but the 100-fold diluted drinking hydrogen water. Became 0 on May 28th. That is, from the measurement results, it was confirmed that the amount of hydrogen generation was larger as the dilution factor was smaller.

FIG. 2 shows a hydrogen water stock solution produced by the mixing ratio shown in the test example on December 18, 2009, with 100 times diluted drinking water (mineral hydrogen content) with mineral water sampled at the Okunagara River. 0.56mg / l) Change in the amount of hydrogen generated from June 21 to July 2, 2010 after 500ml was filled into two 500ml PET bottles and left in the room for 6 months It is a graph which shows the data which measured day by day. In the figure, the indications “12 / 18A” and “12 / 18B” indicate that the drinking hydrogen water produced on December 18 was filled in two 500 ml PET bottles and measured respectively. . And when the drinking hydrogen water of each said PET bottle was measured with the said dissolved hydrogen meter, the amount of dissolved hydrogen was 0.55 mg / l even six months later. That is, it was confirmed that almost no hydrogen escaped from the PET bottle.

As shown in FIG. 1 and FIG. 4, the present inventor is that the hydrogen generation amount is close to zero for the first two to three days after starting measurement, because the drinking hydrogen water uses the magnetic energy of the magnetic stirrer. It was judged that hydrogen was not generated after a certain period of time (2 to 3 days) after absorption, that is, when the induction time had not elapsed.

Furthermore, FIG. 3 shows that 100-fold diluted drinking water produced on July 23, 2010 (dissolved hydrogen amount 0.6 mg / l) was filled into two 500 ml PET bottles. It is the graph which showed the data which measured the change of the amount of residual hydrogen per day from the month 26 to August 3rd. In the figure, the indications “7/23 (1)” and “7/23 (2)” are filled with two 500 ml PET bottles with the drinking water produced on July 23, It shows that it measured, respectively.

Referring to the measurement results shown in FIG. 3, in the first measurement from the day (July 23) to the third day (July 26) from the day when the drinking hydrogen water was filled in the PET bottle, about 8 μg. / L was reduced to 0 on July 27, the second time, and the hydrogen generation increased rapidly from the third day (July 28), and then gradually decreased. On days, it decreased to 0-5 μg / l.

Fig. 4 shows the dissolution of potable hydrogen water obtained by diluting the hydrogen water stock solution produced on February 12, 2010 with mineral water collected from the Okunagara River, 100 times, 90 times and 80 times. It is a graph which shows the data which measured the change of the hydrogen amount by the day unit. In the figure, the indications “100A” and “100B” indicate that two 500 ml PET bottles were filled with 100-fold diluted hydrogen water and measured, and “90A”, “90B”, The same applies to “80A” and “80B”.

When the measurement result shown in FIG. 4 is seen, at the time of the 1st measurement on the 4th day (February 16) from the day (February 12) which filled the drinking hydrogen water into the PET bottle, it is about 8 μg / l. However, the amount of dissolved hydrogen gradually decreased for 3 days thereafter, and decreased to about 2-3 μg / l on February 19th on the 4th day, and then 6 days later. The maximum dissolved hydrogen was generated on February 22nd, and then gradually decreased and reached 0 to 0.5 μg / l on March 4.

From the measurement results shown in FIG. 1 to FIG. 4, the present inventor found that a 100-fold dilution of mineral water is optimal as potable hydrogen water, and at a dilution ratio from 80 to 120-fold dilution before and after 100-fold dilution. If there is, it was judged that it can be drunk as drinking hydrogen water.

As a result of various tests by the present inventor, the following three points are important as drinking hydrogen water, and the order of importance is determined in this order. That is,
1) Delicious.
2) Be transparent. There is no turbidity in the water.
3) High hydrogen content.

From the point of taste, the ratio of Ca and Mg in the hydrogen water stock solution is important, and it is better to have more Ca than Mg as much as possible. On the other hand, in order to make it less turbid, it has been found that it is better to have Mg as much as possible. First, from the viewpoint of taste, in order to obtain the dilution ratio of the hydrogen water stock solution in consideration of both, a comparison of 80, 90, 100, and 120 dilutions shows that a dilution of about 100 times is desirable. Became.

On the other hand, from the point that turbidity does not easily occur, the result is that it is better to have Mg as much as possible than Ca at about 100 times dilution. Eventually, Ca reached a soft water level, but the original taste of the diluted mineral water could be maintained if the dilution was about 80 to 120 times in terms of taste.

Further, as shown in FIG. 1, it was found that the generation amount of hydrogen is smaller as the dilution factor is higher, and the hydrogen generation amount is increased as the dilution factor is lower. Furthermore, in terms of the effect of pH on hydrogen generation, it has been found that, even at pH 2 and pH 12, hydrogen is not generated even if the pH is too low or too high, and pH of 5 to 9 is suitable for generating hydrogen. did.

The present inventor does not use the calcium carbonate and calcium hydroxide used in the white turbid dispersion preparation step of the first step of Example 1, but simply uses magnesium oxide and purified water. It was confirmed that a dispersion could be prepared. Hereinafter, this will be described as a second embodiment.

Example 2 in the manufacturing method of the drinking hydrogen water which can be filled in the PET bottle of this invention is demonstrated in detail. The manufacturing method of the drinking hydrogen water which can be filled in the PET bottle which concerns on Example 2 of this invention is manufactured by the following 1st processes-4th processes. That is, the method for producing potable hydrogen water that can be filled in the PET bottle of the present invention is as follows.

A third step of producing a hydrogen water stock solution by electrolyzing the mixed solution produced in the second step until the redox potential of cathodic water is -500 mV or less;
From the fourth step, the hydrogen stock solution produced in the third step is diluted 80 to 120 times with mineral water to produce a potable hydrogen water having a hydrogen content in the range of 0.01 to 0.8 mg / l. Become. The respective steps are substantially the same as those in the first embodiment, and a detailed description thereof will be omitted.

Next, an example of a test for producing potable hydrogen water using the method for producing potable hydrogen water that can be filled in a PET bottle according to Example 2 of the present invention will be described in detail. The following operations were all performed at room temperature.

A cloudy dispersion liquid comprising the components shown in the following (A) was prepared. To this dispersion, a phosphoric acid (H ₃ PO ₄ ) aqueous solution composed of the following component (B) was mixed and reacted. When mixed, the solution temporarily became transparent, but finally became cloudy, and a mixed solution in which very fine particles were dispersed (1000 g) was obtained. Furthermore, when a citric acid aqueous solution composed of the following component (C) was added to the mixed solution of (A) and (B), the cloudy liquid became a transparent colloidal solution. The total amount of colloidal liquid (A + B + C) was 5000 g (hereinafter referred to as “3 liquids”). In addition, the weight of each raw material which manufactures the cloudy dispersion liquid of the following (A)-(D), phosphoric acid aqueous solution, citric acid aqueous solution, and alkaline aqueous solution is in the range as described in the said preferable mixture ratio.

Next, when a small amount of the three liquids is added to an alkaline aqueous solution composed of the components shown in the following (D), it becomes a cloudy dispersion and immediately becomes a transparent liquid. Subsequently, the three liquids were further added until the pH reached 6.5 (pH test paper). As a result, when 5000 g of the third solution was added, the pH became 6.5 (pH test paper). The total amount of the obtained aqueous solution (hereinafter referred to as “four liquids”) was 10,000 g.

The four solutions were subjected to electrolysis for 100 minutes by flowing a direct current of 10 A at 5 to 15 V. As a result of measuring the hydrogen content of the four liquids and the hydrogen content in the solution after electrolysis in the same manner as in Example 1, the hydrogen content before electrolysis was 0.01 mg / l, whereas The hydrogen content of was 0.56 mg / l.

And the hydrogen water stock solution after electrolysis (hydrogen content 0.56 mg / l) was diluted 100 times with mineral water. When the obtained 100-fold diluted solution (dissolved hydrogen amount 0.006 mg / l) was energized with 5 to 15 V and 10 A for 15 minutes, the dissolved hydrogen amount was 0.6 mg / l.

Further, the hydrogen water stock solution (hydrogen content 0.56 mg / l) was diluted 100 times with mineral water. The obtained 100-fold diluted drinking hydrogen water (dissolved hydrogen amount 0.006 mg / l) was heated at 85 ° C. for 40 minutes, and then energized with 5 to 15 V and 10 A for 15 minutes. 56 mg / l.

500 ml of the potable hydrogen water (dissolved hydrogen amount 0.5 mg / l) was filled in a 500 ml PET bottle and allowed to stand naturally in the room. As a result, the residual hydrogen amount was 0.49 mg / l even after 6 months.

In addition, the measurement data about the result of having diluted the hydrogen water stock solution manufactured by Example 2 with mineral water is not shown. The difference between the hydrogen water stock solution produced in Example 1 and the hydrogen water stock solution produced in Example 2 is that Example 2 uses in the white turbid dispersion preparation step of the first step of Example 1 above. This is the point that a hydrogen water stock solution is produced simply using magnesium oxide and purified water without using calcium carbonate and calcium hydroxide. And the hydrogen water stock solution manufactured by the said Example 2 is also diluted with mineral water as a final product. Since the mineral water naturally contains calcium, when the hydrogen water stock solution prepared in Example 2 is diluted with mineral water, the hydrogen water stock solution prepared in Example 1 is diluted with mineral water. It becomes the same potable hydrogen water. Therefore, it is considered that the measurement data shown in FIGS. 1 to 4 can also be applied to potable hydrogen water obtained by diluting the hydrogen water stock solution produced in Example 2 with mineral water.

Hydrogen water is one of the typical functional waters that has been attracting attention recently, but the added citric acid, which is presumed to be involved in the solubilization of the hydrogen sorption component, is the in vivo citrate cycle. Since it is an important component and the main component of the citric acid health method, the hydrogen water obtained by the method of the present invention is not a mere hydrogen water, but a next-generation functional water.

Then, the inventors have the subject drink the drinking hydrogen water obtained in Example 2 and determine how the drinking affects the living body by measuring the skin impedance change before and after drinking. Asked.

Measurement method Changes in skin after drinking hydrogen water before and after drinking using pre-care nady (Misawa skin impedance measuring device AMI-100 <medical device manufacturing approval number (04B) 0768>) (Hereinafter referred to as AMI measurement) and observe the state of the living body. Specifically, electrodes are attached to the limbs, a voltage of 3 V is applied for a very short time, the current flowing between the electrodes is measured at that time, and the reaction of the living body is evaluated with the following three parameters. Among these parameters, the BP average value is the most important.
BP average value: body fluid circulation and air flow parameter IQ average value: defense function of living body-immunity parameter AP average value: autonomic nervous system parameter

In order to see the reproducibility, the measurement was performed twice for one male subject by changing the date and time. The measurement data was displayed as A (58 years old) and A ′ (58 years old). In the same manner as described above, one female subject was measured twice with different dates. The measurement data was displayed as H (56 years old) and H ′ (56 years old). In addition, one female subject was measured only once. The measurement data was displayed as Y (84 years old). There are five test subjects. The measurement was performed before drinking, immediately after drinking, after 5 minutes, and after 10 minutes. The amount of hydrogen water to be drunk at one time was 1 cup (180 ml).

Measurement result (1) Subject A (male 58 years old)
Table 1 summarizes the results. The BP average value slightly increased immediately after drinking, further increased after 5 minutes, and decreased slightly after 10 minutes. The IQ average value showed a tendency to increase. However, there is no significant change in the AP average value.

(2) Subject A '(male 58 years old)
Table 2 summarizes the results. The BP average value, IQ average value, and AP average value tended to increase with the passage of time.

(3) Subject H (female 56 years old)
Table 3 summarizes the results. The BP average value once increased after drinking, but then decreased slightly and increased again. The IQ average value rose remarkably after drinking, but then decreased slightly and increased again. There is no significant change in the AP average value.

(4) Subject H '(Female 56 years old)
Table 4 summarizes the results. The BP average value once increased after drinking, but then gradually decreased. The BP average value was lower than before drinking. There is no significant change in the IQ average or AP average.

(5) Subject Y (female 84 years old)
Table 5 summarizes the results. The BP average value, IQ average value, and AP average value increased considerably after 10 minutes from before drinking.

From the above measurement results, the BP average value representing the body fluid circulation and the air flow and the IQ average value representing the defense function of the living body increased in 5 out of 5 people after 10 minutes passed after drinking the drinking water. Showed a trend. This result shows that hydrogen water has the effect of smoothing the circulation of body fluids and improving the flow of air, and further promoting the defense function. In particular, since the influence is remarkable in the subject Y (female 84 years old), it seems to be particularly effective for a person whose physical strength has declined due to age.

Judging from the measurement result of the impedance change, the potable hydrogen water obtained by the production method of the present invention can be expected to have a great effect as a health drink and can be filled into a plastic bottle. Since it is not necessary to use it, it can be provided at low cost.
