Description

[Technical Field]

[0001] The present invention relates to a method for producing water having a reduction potential (reduced water). More specifically, the present invention relates to a stock solution (reduced stock solution) for producing reduced water, and a method for producing reduced water using the reduced stock solution as a raw material. [Background technology]

[0002] Water with a reducing potential (hereinafter simply referred to as "reduced water") is said to be good for health and beauty because it prevents oxidation in the human body. However, commonly available tap water is said to have a high potential, in the positive range. For example, it is known that the potential of tap water in each municipality in Tokyo is relatively high, in the positive range of +500 to +700 mV (Non-Patent Document 1). This means that people are exposed to the risk of oxidation on a daily basis.

[0003] One of the widely known types of reduced water is hydrogen water. Hydrogen water is water in which hydrogen gas is dissolved, and various technologies have been disclosed for water with reducing power (Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0006] However, hydrogen water has several problems. One reason is that hydrogen itself is not necessarily highly soluble in water, so pressure is required to keep it dissolved. Therefore, once a container of hydrogen water is opened, the pressure inside the container decreases, and the solubility of hydrogen in water decreases. As a result, the hydrogen escapes from the hydrogen water. Because of this, hydrogen water has low solubility in water, and so it has been difficult to maintain, manage, and store the hydrogen in a dissolved state.

[0007] Another issue with hydrogen water is that the hydrogen molecules themselves are small, so if hydrogen water is stored in a general-purpose container such as a plastic bottle, the hydrogen will leak out of the container. This necessitates the use of containers made of a material with a relatively high molecular weight, such as an aluminum pouch, which is not very economical.

[0008] In light of the above circumstances, the present invention aims to develop stable reduced water that differs from hydrogen water. [Means for solving the problem]

[0009] As a result of extensive research, the inventor came up with the idea that by blending various materials and maturing them, it is possible to produce water with a reducing potential, and thus completed the invention.

[0010] The present invention comprises the following configurations. [1] A material addition process in which kumquats, lemons, ginkgo leaves, silverleaf, kudzu, mugwort, citrus leaves, ice plant, and sake are added to water. After the material addition process, there is a heating process of heating water, After the heating process, the heated water is left to stand and return to room temperature. A method for producing a reduction stock solution, comprising:

[0011] [2] Furthermore, a method for producing a reducing concentrate described in [1], in which tea is added in the material addition step.

[4] A method for producing a reduced raw solution according to any one of [1] to [3], further comprising a water quality improvement pretreatment step in which ceramic balls are added to the water and left to stand, thereby improving the water quality.

[0012] [5] Each step in any one of the manufacturing methods described in [1] to [4]; The dilution and settling process involves adding the reduced stock solution to the treated water, which has been treated by adding a ceramic ball and leaving it to stand, diluting it, mixing it thoroughly, and leaving it to stand.

[0015] The present invention will now be described.

[0016] The method for producing the reduced raw solution or reduced water of the present invention was completed based on the following experimental facts. (1) By placing a ceramic ball in tap water and leaving it standing, it is possible to lower the electrical potential of the tap water. (2) The water treated by (1) above (water quality improved treated water or modified water) can be treated with the specified ingredients (kumquat, lemon, ginkgo leaves, salicylic acid, kudzu, mugwort, citrus leaves, ice plant, sake) and then heated and allowed to stand to produce the specified solution (reducing concentrate). (3) By adding tea components to the reduced raw solution during heating and carrying out the process described below, it is possible to produce tea with reducing ability (reduced tea). (4) When the reduced stock solution was diluted and left to stand (reduced water), a decrease in potential was observed, reaching a potential of approximately -500 mV about 48 hours after the start of dilution. Thereafter, the potential of approximately -500 mV can be maintained for at least 200 hours after dilution. (5) The negative potential of reduced water is maintained even in a plastic container.

[0017] The method for producing the reducing concentrate of the present invention is characterized by comprising an ingredient addition step of adding kumquat, lemon, ginkgo leaves, salicylic acid, kudzu, mugwort, citrus leaves, ice plant, and sake to water, a heating step of heating the water after the ingredient addition step, and a room temperature standing step of leaving the heated water to stand and return it to room temperature after the heating step. The reduced raw liquid produced through this series of steps can be made into reduced water or reduced tea (hereinafter collectively referred to as "reduced water, etc.") through a series of treatments described below. Such reduced liquid, etc. is a liquid with a negative potential, and can maintain a negative potential even in a plastic container. For this reason, reduced liquid, etc. is expected to be a new reduced liquid that can be used by people as a beverage.

[0018] In the method for producing the reducing solution of the present invention, the material addition step is a step of adding a material that will serve as a starting point for inducing a reduction potential to water (tap water or modified water). The material addition step does not need to be particularly limited as long as such a predetermined material can be added, and can be carried out by various methods. The ingredient addition step is typically carried out by adding the specified ingredients to a container such as a pot filled with water. As an example, for approximately 2 L of water, 10 kumquats, 1 lemon, 25 g of ginkgo leaves (dried), 10 g of salicylic acid (dried leaf portion), 20 g of kudzu (dried leaf portion), 10 g of mugwort (dried leaf portion), 25 g of citrus leaves (dried mandarin orange leaves), 40 g of ice plant (frozen vegetable), and 80 cc of sake can be added. Furthermore, 30 g of dried Japanese tea can be added as a tea ingredient, as described below.

[0019] In the material addition step of the present invention, it is preferable to add tea, which allows the reduced liquid produced when the reduced stock solution is diluted to be used as a tea beverage, thereby improving the usefulness of the manufacturing method of the present invention. There is no particular limitation on the type of tea used, as long as it can be added as tea leaves, and various types of tea can be used. Examples of such tea include green tea, barley tea, buckwheat tea, oolong tea, and black tea. These teas may be added alone or in combination. The reduced water finally produced in the present invention does not necessarily have to be limited to water or tea. In other words, it is possible to produce beverages other than water or tea by adding ingredients other than tea in the ingredient addition step or after producing reduced water.

[0020] In the present invention, it is preferable to further include a water quality improvement pretreatment step in which ceramic balls are added to the water and left to stand as a pretreatment to improve the water quality. This makes it possible to lower the electric potential of the water, which has the effect of improving the efficiency of producing the reduced solution or reduced water. The ceramic ball is, for example, a spherical object made of ceramics with a diameter of about 1.0 to 2 cm as shown in FIG. 1. Such ceramic balls may be added by adjusting the size and number so that they are typically 0.05 to 0.4 volume, preferably 0.05 to 0.3 volume, more preferably 0.05 to 0.25 volume, particularly preferably 0.05 to 0.2 volume, and most preferably 0.1 to 0.2 volume per 1 L of tap water. After performing such treatment, by allowing to stand for a sufficient time, it is possible to obtain reformed water with a reduced potential.

[0021] The reducing stock solution is diluted in addition to such reformed water (water quality-improved treated water), thoroughly mixed, and allowed to stand (dilution and standing step) to obtain reducing water. Such reducing water is a liquid having a reducing ability with a negative potential. The dilution ratio of the water quality-improved treated water to the reducing stock solution (water / reducing stock solution v / v) can be adjusted as appropriate, but is typically 10 to 100 times, preferably 10 to 80 times, more preferably 10 to 60 times, particularly preferably 20 to 60 times, and most preferably 20 to 50 times. Also, the time for dilution and standing can be adjusted as appropriate, but is typically 20 to 220 hours, more preferably 30 to 220 hours, particularly preferably 40 to 220 hours, and most preferably 45 to 220 hours. Also, the reducing stock solution can be diluted using tap water. In such a case, although the reduction in potential is delayed compared to the case of using reformed water, by allowing sufficient standing, it is possible to reach a reduction potential comparable to that in the case of using reformed water.

Example

[0022] The present invention will be described with reference to examples.

[0023] <<I. Method for producing reducing stock solution and reducing water>> 1. The ceramic ball (FIG. 1) was placed in tap water and allowed to stand at room temperature for 20 to 24 hours. Thereafter, the tap water subjected to such treatment is referred to as reformed water (water quality-improved treated water). 2. Figure 2 shows the change in potential before and after treatment. (1) Tap water showed a potential of +640 mV (Figure 2, left). (2) In contrast, the modified water showed a potential of +355 mV (Figure 2, right), a decrease of approximately 45% in potential compared to tap water. (3) From these findings, it was confirmed that the potential decreased due to treatment with ceramic balls.

[0024] 3. Next, approximately 2000 mL of modified water was placed in a container (pot) and the following ingredients were added. (1) 10 kumquats (2) 1 lemon (3) 25g ginkgo leaves (dried) (4) 30g dried Japanese tea (5) Urajiro (dried leaves) 10g (6) 20g of kudzu (dried leaves) (7) 10g of mugwort (dried leaves) (8) Citrus leaves (dried mandarin orange leaves) 25g (9) Ice plant (frozen vegetable) 40g (10) Sake 80cc 4. After adding all the ingredients, heat the mixture until it boils, stirring constantly to ensure that all the ingredients are thoroughly submerged. 5. After boiling, turn off the heat and let it stand until it reaches room temperature. 6. After the temperature reached room temperature, the contents were filtered to obtain only the liquid. Hereafter, the liquid obtained through this series of operations is referred to as the reduction stock solution. 7. The appearance of the reduction stock solution is shown in Figure 3. The reduction stock solution was prepared as a clear brown liquid.

[0025] 8. Approximately 330 mL of the reduction stock solution was added to 10 L of reformed water in a container (polyethylene tank) and mixed thoroughly. Figure 4 shows the state immediately after mixing. The reduction stock solution was diluted and became a clear, light brown liquid. 9. After mixing, the liquid temperature in the poly-tank was maintained at approximately 20 to 28 °C and allowed to stand for about 24 hours for aging. 10. The liquid in the poly-tank after aging was used as the reduced tea for subsequent tests.

[0026] <<II. Comparative Measurement of Reduction Potential>> 1. For the reduced tea produced in I (Experimental Example 1, reduced tea with reformed water raw material), the potential was measured by the platinum electrode method. The state of potential measurement is shown in Fig. 5. 2. Separately, the same production operations were carried out using tap water without using ceramic balls (Experimental Example 2, reduced tea using tap water), and the potential of the tap water was measured.

[0027] 3. The results are shown in Table 1. (1) The potential of the tap water (untreated) was +630 mV. (2) On the other hand, in Experimental Example 1, it was +78 mV 24 hours after treatment, but reached -500 mV at 48 hours, and thereafter fluctuated around -450 mV. (3) Also, in Experimental Example 2, it was +160 mV both 24 hours and 48 hours after treatment, but reached -490 mV at 72 hours, and thereafter also fluctuated from -480 mV to -470 mV.

[0028] 4. From these results, the following was found. (1) Compared with the potential of tap water, a significant decrease in potential was confirmed by using a series of production methods. (2) By a series of production methods, a significant decrease in potential of about -500 mV was observed regardless of whether reformed water or tap water was used as the raw material. (3) Once the potential decreased to a peak of about -500 mV, a slight increase in potential was observed, and relatively stably, the potential fluctuated and remained in the negative region. In addition, since the negative potential region was maintained even when using a plastic poly-tank container, it was strongly suggested that it was possible to maintain a negative potential even in a PET bottle or the like. (4) In the series of manufacturing methods, the use of modified water as raw material resulted in a more rapid decrease in potential than the use of tap water as raw material.
