Description

Oxygen-containing reducing water beverage and production method thereof

Technical Field

The present invention relates to an oxygen-containing reducing water beverage which is rich in oxygen and has high reducing property at the same time, and a production method thereof.

Background

Hitherto, water having a low redox potential has been produced by electrolysis (see patent documents 1 to 3 below) or by dissolving hydrogen under pressure (see patent document 4 below). Therefore, from the viewpoint of dissolving hydrogen in water, mineral water, tea, coffee, fruit juice, and other water beverages under pressure alone, it is presumed that it is possible to produce a reducing water beverage having a low oxidation-reduction potential.

Although a reducing water drink can be produced by such a hitherto known production method, the reducing water drink contains almost no oxygen necessary for the body. Incidentally, the oxygen content of the reducing water in which hydrogen was dissolved under pressure was 0.04mg/L (measured using an oxygen concentration meter manufactured by Toyo DKK). Of course, only a reducing water drink having a low oxygen content can be obtained because oxygen originally contained in the water drink is driven out by hydrogen.

That is, in order to obtain a reducing water drink having a high oxygen concentration, it is impossible to adopt a method of simply dissolving hydrogen in a water drink such as water, mineral water, tea, coffee, or fruit juice under pressure to improve the reducing property of the water drink. In particular, when hydrogen gas bubbles in a water beverage, other gases such as oxygen cannot coexist because of only the partial pressure of hydrogen gas, and the gas is completely degassed except for hydrogen gas. That is, oxygen necessary for human beings is lost from the water beverage.

In addition, in the case of producing a water beverage of low oxidation-reduction potential by the method of electrolysis, it shows alkalinity only due to OH "ions, and does not contain hydrogen gas at a saturated concentration or more. If it is basic, it apparently shows reducibility due to the reduction power generated by OH-ions, but when it returns to neutrality, the redox potential rises. That is, only the reducibility of the table is shown in vain. In addition, if a large amount of alkaline solution is drunk, health problems occur. Especially, the burden on the kidney is increased, and therefore, it is harmful to the renal-impaired. On the other hand, although it is thought that a slight effect is produced if the drinking water is used in a proper amount for people with gastric hyperacidity, the effect is produced by neutralizing gastric acid with an alkaline solution, not by hydrogen or reducing power.

Further, a method of obtaining reducing water by mixing metallic magnesium into a water drink is known, but in this case, magnesium ions are generated simultaneously with hydrogen gas, and therefore, the water drink has basicity. Although a suitable amount of magnesium ions can be introduced into a drug for constipation or the like, it is dangerous to prevent the body from continuously maintaining the function of a neutral environment because a large amount of alkaline water drink is taken as described above. To the extent that alkalinity alone is not exhibited, merely dissolving hydrogen may be considered preferable instead.

Disclosure of the invention

Technical problem to be solved by the invention

The present inventors have made various experiments to obtain an oxygen-containing reducing water drink which is rich in oxygen necessary for the human body and has an extremely high hydrogen concentration and an extremely low oxidation-reduction potential, and as a result, have found that a reducing water drink which contains a rich amount of oxygen and has an extremely high hydrogen concentration and an extremely low oxidation-reduction potential can be obtained by adding oxygen or hydrogen to a water drink under pressure and then adding hydrogen or oxygen to the water drink, or by adding oxygen and hydrogen to the water drink simultaneously, and have completed the present invention.

Oxygen and hydrogen do not react at normal temperature, and therefore do not naturally react in the human body. Taking these into account, it will be understood and appreciated that it is possible to produce a water beverage containing both oxygen and hydrogen.

Accordingly, it is a first object of the present invention to provide a reducing aqueous beverage obtained by containing both oxygen and hydrogen in an aqueous beverage which is rich in oxygen and has an extremely high hydrogen concentration and an extremely low oxidation-reduction potential.

It is a second object of the present invention to provide a method for producing a reducing water beverage which contains oxygen and hydrogen at the same time, is rich in oxygen, and has an extremely high hydrogen concentration and an extremely low oxidation-reduction potential.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, as described in detail in the following examples, the reducing water beverage of the prior art which absorbs hydrogen only cannot provide the oxygen content necessary for the body because the oxygen content is very small. In contrast, according to the present invention, an oxygen-containing reducing water beverage having a very low oxidation-reduction potential due to hydrogen that can permeate cell membranes and having oxygen content necessary for the body can be obtained.

Best mode for carrying out the invention

Specific examples of the present invention will be described in detail below with reference to examples, but the following examples are not intended to limit the present invention. Various changes made without departing from the technical idea shown in the claims are within the scope of the present invention.

Example 1

In the example of the present invention, oxygen was dissolved in 1 liter of commercially available spring water ([ di '/' こ person ] (trade name) produced by nestle corporation) at a pressure of 6 atm for 10 minutes at a ratio of 200 l/min using a known gas-liquid contact device, and then hydrogen was dissolved in 1 liter of water containing oxygen at a pressure of 6 atm for 10 minutes at a ratio of 200 l/min.

As the reducing water of example 1, it was possible to produce a more desirable water having an oxygen content of 3.20mg/l, a hydrogen concentration of 0.96ppm, a pH of 7.4, and an oxidation-reduction potential of-650 mv. The results are summarized in Table 1. In addition, measurement of the oxidation-reduction potential, oxygen content, hydrogen concentration and pH was performed at room temperature using an OPR meter, an oxygen content meter, a hydrogen concentration meter and a pH meter, all manufactured by east asia DKK.

	Oxidation reduction potential oxygen content	Hydrogen concentration
			Commercially available water	+320mv0.48mg/l	0.00ppm
Water containing oxygen	+355mv54.32mg/l	0.00ppm
			Water having hydrogen dissolved in water containing oxygen	-650mv3.20mg/l	0.96ppm

Example 2

In example 2, a commercially available tea beverage was prepared. The tea beverage has an oxidation-reduction potential of +60mv, a dissolved oxygen content of 1.55mg/l, and a pH of 6.1. The tea beverage was fed into an eductor at 500 ml/min under a pressure of 8 atm and oxygen gas was fed into the eductor at 150 ml/min under a pressure of 8 atm at the same time, and after oxygen was dissolved, the pressure was returned to normal pressure, whereby an oxygen-containing tea beverage having a dissolved oxygen content of 31.00mg/l was obtained.

The oxygen-containing tea beverage was fed to the ejector at a rate of 500 ml/min under a pressure of 8 atm and hydrogen gas was fed again at a rate of 150ml under a pressure of 8 atm, and after dissolving the hydrogen gas, the tea beverage was returned to normal pressure, whereby an oxygen-containing reducing tea beverage having a dissolved oxygen content of 4.50mg/l, a pH of 6.1 and an oxidation-reduction potential of-599 mv was obtained.

Example 3

A commercially available coffee beverage was prepared in example 3. The coffee beverage had an oxidation-reduction potential of +85mV, a dissolved oxygen content of 1.22mg/l and a pH of 5.0. The coffee beverage was supplied to an injector at a rate of 500 ml/min under a pressure of 8 atm and oxygen gas was supplied at a rate of 150 ml/min under a pressure of 8 atm at the same time, and after dissolving oxygen gas, the coffee beverage was returned to normal pressure to obtain an oxygen-containing reducing coffee beverage having a dissolved oxygen content of 32.70 mg/l.

The oxygen-containing coffee beverage was supplied to the ejector at a rate of 500 ml/min under a pressure of 8 atm and at a rate of 150 ml/min under a pressure of 8 atm with hydrogen gas again at the same time, and after dissolving the hydrogen gas, the pressure was returned to normal pressure, whereby an oxygen-containing reducing tea beverage having a pH of 5.0, a dissolved oxygen content of 6.51mg/l and an oxidation-reduction potential of-428 mV was obtained.

In addition, although examples in which oxygen gas is first dissolved in a water beverage and then hydrogen gas is re-dissolved are shown in the above-described examples 1 to 3, hydrogen gas may be first dissolved in a water beverage and then oxygen gas may be re-dissolved in the reverse order. Further, the same effect can be obtained by supplying oxygen and hydrogen simultaneously in a water beverage, but since a mixed gas of oxygen and hydrogen is easily burned or exploded by electrostatic discharge, special attention must be paid to exposure prevention when this method is employed.
