Description

  The present invention relates to a hydrogen-containing beverage containing a functional raw material.

  In recent years, hydrogen-dissolved water in which hydrogen gas is dissolved in (ultra) pure water (also simply referred to as hydrogen water), which is also used for cleaning semiconductor silicon substrates and glass substrates for liquid crystals, has high reducibility Therefore, it is said that it has the effect of suppressing metal oxidation and food spoilage, and when it is diverted to drinking, it is attracting attention as being expected to improve various health disorders.

As a method for producing the above-described drinking hydrogen-dissolved water, for example, there is a method in which hydrogen gas from a gas cylinder or hydrogen gas generated by electrolysis of water is dissolved in raw water. However, simply supplying hydrogen gas to the raw water causes nitrogen gas, oxygen gas, etc. dissolved in the raw water to interfere with the dissolution of hydrogen gas at room temperature and atmospheric pressure. It is far from the saturated concentration.
For this reason, for example, hydrogen gas is filled in a pressure vessel from which air has been removed, and the raw water is sprayed into the pressure vessel in a shower-like manner while maintaining the hydrogen gas pressure in the pressure vessel at 2 to 10 atm. A method for efficiently dissolving hydrogen gas by bringing it into contact with hydrogen gas has been proposed (Patent Document 1).
Alternatively, a method has been proposed in which hydrogen gas is injected into water at high pressure to generate ultrafine bubbles (so-called “nanobubbles” and “microbubbles”), which are dissolved in water (Patent Document 2).

By the way, paying attention to the high reducibility of beverages in which hydrogen gas is dissolved, such as the hydrogen water described above, redox potential can be obtained by dissolving hydrogen in tea, coffee, soft drinks, vegetable juice, etc. Various proposals relating to beverages with a low content have also been made (Patent Documents 3 to 5).
In addition, it is important for beverages in which hydrogen is dissolved to maintain high reducibility with little loss of dissolved hydrogen from production to actual consumption. It has been proposed to add an active substance) (Patent Documents 6 and 7).

Japanese Patent No. 3606466 JP 2011-230055 A JP 2004-329188 A JP 2004-344862 A JP 2005-21146 A JP 2005-296794 A International Publication No. 2008-062814 Pamphlet

However, conventionally proposed hydrogen-containing beverages have a problem that hydrogen gas cannot be efficiently dissolved in the raw water (liquid) and the hydrogen concentration varies from lot to lot.
In addition, even in beverages that maintain high reducibility by adding antioxidant substances (reducing substances), hydrogen-containing water (hydrogen-containing drinks) obtained by conventional methods has its own hydrogen concentration. There was a problem that it was low and could not provide a beverage having a desired redox potential.
Furthermore, even if a hydrogen-containing beverage having a high dissolved concentration hydrogen concentration can be produced, there has been a problem that the dissolved hydrogen concentration is greatly reduced during storage.

  As a result of intensive studies on natural ingredients and drinkable materials that can be added to hydrogen-containing water in order to solve the above-mentioned problems, the present inventors preferred specific functional raw materials such as cherry blossom extracts for hydrogen water. By blending in an amount to make a hydrogen-containing beverage, the resulting hydrogen-containing beverage can maintain a high dissolved hydrogen concentration for a long period of time, and the resulting hydrogen-containing beverage becomes a non-colored, odorless, tasteless material and other beverage By finding that the components can be freely blended, and by degassing the remaining gas from the raw water as the hydrogen water to be used, and dissolving the hydrogen gas through this gas-permeable hollow fiber membrane The present inventors have found that a hydrogen-containing beverage maintaining a high dissolved hydrogen concentration can be obtained by using hydrogen water having a higher dissolved hydrogen concentration more efficiently, and the present invention has been completed.

  That is, the present invention is a cherry blossom flower extract containing at least one selected from the group consisting of caffeoyl glucose, quercetin glucoside, coumaroyl glucose, cinnamoyl glucose, kaempferol glucoside, quercetin malonyl glucose and kaempferol malonyl glucose; Apple polyphenol containing at least one of procyanidins and quercetin; Kiwi seed extract containing at least one of quercitrin and kaempferol 3-O-rhamnoside; methyl hesperidin; theanine; containing at least one of spermidine, spermine and putrescine At least one functional raw material selected from the group consisting of polydextrose; polydextrose; and rose flower extract containing eugenin It relates to a hydrogen-containing beverage in which the hydrogen gas is blended to hydrogen water dissolved.

  The hydrogen-containing beverage is produced by degassing water as a raw material and dissolving hydrogen gas in the hydrogen-containing beverage through a gas-permeable hollow fiber membrane, and the functional raw material is added to the produced hydrogen water. Or the functional raw material is dissolved or mixed in water as a raw material, degassed, and hydrogen gas is passed through a gas-permeable hollow fiber membrane. It is preferable to be prepared by dissolving

  Generally, the hydrogen-containing beverage of the present invention preferably contains the functional raw material in a proportion of 0.001% by mass to 20% by mass with respect to the total mass of the hydrogen-containing beverage. However, the amount of each functional ingredient added is set in such a range that the hydrogen-containing beverage can maintain the non-colored, odorless, and tasteless properties effectively, and can maintain a high dissolved hydrogen concentration as long as possible. .

According to the present invention, a high concentration of dissolved hydrogen can be maintained for a long period of time in the obtained hydrogen-containing beverage by blending functional raw materials such as cherry blossom extract into hydrogen water.
In addition, because it uses food additives approved by the Food and Food Sanitation Law as functional raw materials, it does not adversely affect the human body, and these functional raw materials are dissolved in hydrogen gas at a high concentration. By blending with hydrogen water, a hydrogen-containing beverage having a low oxidation-reduction potential can be obtained.

In the hydrogen-containing beverage of the present invention, the functional raw material selected from the group consisting of cherry blossom extract, apple polyphenol, kiwi seed extract, methyl hesperidin, theanine, polyamine, polydextrol, rose flower extract is hydrogen water.

The hydrogen-containing beverage of the present invention produces hydrogen water by degassing water as a raw material and dissolving hydrogen gas through the gas-permeable hollow fiber membrane, and the function is added to the produced hydrogen water. It is prepared by dissolving or mixing the raw material.
Alternatively, the hydrogen-containing beverage of the present invention is prepared by dissolving or mixing the functional raw material in water as the raw material, degassing it, and dissolving hydrogen gas through the gas-permeable hollow fiber membrane. Being done.
In addition, it is also possible to make a hydrogen-containing beverage by degassing the functional raw material liquid (eg, vegetable juice, milk, etc.) itself and dissolving the hydrogen gas through the gas-permeable hollow fiber membrane.

  The hydrogen-containing beverage prepared as described above can be sterilized and sterilized normally for serving as a beverage, and impurities can be removed from the raw water or the water in which the functional raw material is mixed or dissolved. It can also be filtered and / or purified before degassing to eliminate.

The method of dissolving hydrogen in water as a raw material or water in which a functional raw material is mixed or dissolved is, for example, a method disclosed by the present inventors in a previous patent application (Japanese Patent Application No. 2009-123310). The content of the same application is hereby incorporated by reference.
Specifically, the method includes (a) a purification step, (b) a deaeration step, (c) a hydrogen dissolution step, and (d) a sterilization step, and each step is continuously performed in a closed system. It is characterized by doing.

(A) Purification step This step is a step of filtering water that is a raw material in the purification device and sending the obtained purified water to a deaeration device. In the present invention, it is also possible to filter the water in which the functional raw material is dissolved in the raw water and send it to the deaerator.
The water used as a raw material is not particularly limited as long as it is supplied from a water source suitable for drinking, such as tap water (water supplied for water supply business, water supplied by a dedicated water supply or simplified dedicated water supply), groundwater, etc. Can be mentioned.
The purification device includes an activated carbon filtration device and a membrane filtration device.
The activated carbon filter removes the musty odor of water, trihalomethane, and dechlorination treatment. In addition, it removes suspended solids (including activated carbon), bacteria such as Escherichia coli, and pathogenic protozoa such as Cryptosporidium by a safety filter.
Examples of membranes that can be used in membrane filtration devices include microfiltration membranes (MF membranes), ultrafiltration membranes (UF membranes), nanofilter membranes (NF membranes), and reverse osmosis membranes (RO membranes). In view of the remaining of mineral components that determine the taste when drinking, it is desirable to use an MF membrane. Membrane permeation treatment can also be performed using NF membrane or RO membrane, but since mineral components dissolved in raw water such as sodium ions and potassium ions are removed, these mineral components are used to make water suitable for drinking. Since the residual ratio needs to be adjusted or newly added, the operation becomes complicated, which is not preferable.

(B) Degassing step This step is a step of degassing the purified water supplied to the degassing device and sending the obtained degassed water to the hydrogen dissolving device.
The degassing device is not particularly limited as long as it can degas a dissolved gas such as oxygen gas, nitrogen gas, and carbon dioxide gas. For example, a vacuum degassing device or a gas permeable membrane built-in module (gas degassing membrane module) However, since a gas dissolved in a small amount can be efficiently degassed, it is preferable to use a degasser equipped with a gas degassing membrane module.
The gas degassing membrane module is partitioned into a water chamber and a gas chamber by a gas degassing membrane, passes the purified water through the water chamber, and depressurizes the gas chamber, thereby degassing the dissolved gas flowing into the water chamber. To do.
The type of gas degassing membrane (hollow fiber membrane) used in this step is not particularly limited. For example, polypropylene, polydimethylsiloxane, polycarbonate-polydimethylsiloxane block copolymer, polyvinylphenol-polydimethylsiloxane-polysulfone block copolymer Examples thereof include polymer films such as coalescence, poly (4-methylpentene-1-), poly (2,6-dimethylphenylene oxide), and polytetrafluoroethylene.
In order to increase the efficiency of deaeration, this step may be performed under heating. In that case, in order to increase the efficiency of subsequent hydrogen dissolution, it is desirable to cool to room temperature (around 25 ° C.). .

(C) Hydrogen dissolution step This step is a step of dissolving hydrogen gas in deaerated water supplied to the hydrogen dissolution apparatus and sending the obtained hydrogen dissolution water to the sterilization apparatus.
As the hydrogen dissolving apparatus, a hydrogen dissolving apparatus equipped with a gas permeable membrane module is used because the amount of hydrogen gas dissolved per unit time and unit space is large and it is easy to improve the dissolution efficiency of hydrogen gas.
The gas permeable membrane module is divided into a water chamber and a gas chamber by a gas permeable membrane, passes the degassed water through the water chamber, and supplies hydrogen gas to the gas chamber, thereby supplying degassed water flowing into the water chamber. Hydrogen gas is dissolved in
Examples of the gas permeable membrane used in this step include the polymer membranes mentioned as the gas degassing membrane.

There is no restriction | limiting in particular in the supply method of hydrogen gas, For example, the hydrogen gas obtained by the electrolysis etc. of a commercially available high purity hydrogen gas cylinder or water can be used.
Further, when supplying hydrogen gas to the gas chamber of the gas permeable membrane module, the dissolved hydrogen concentration is increased by supplying hydrogen gas at a pressure higher than atmospheric pressure, for example, about 1.2 to 2.0 atm. be able to. However, if a pressure exceeding 2.0 atm is applied, it is necessary to improve the pressure resistance and airtightness of various facilities of the gas permeable membrane module, which leads to an increase in manufacturing cost, which is not preferable.

(D) Sterilization process This process is a sterilization process of sterilizing the hydrogen-dissolved water supplied to the sterilizer.
The sterilizer includes an ultraviolet irradiation device and a membrane filtration device, sterilizes hydrogen-dissolved water with the ultraviolet irradiation device, and again removes suspended matters, bacteria, and the like with the membrane filtration device.
Also in this step, it is preferable to use an MF membrane filtration device as in the purification device, but the suspended matter and the like are completely removed by using an MF membrane having a pore diameter smaller than that of the MF membrane used in the purification device. It is more desirable because it can.

  A part of the hydrogen water obtained in the step (d) is returned to the degassing device in the step (b), and water is circulated between the steps (b) to (d). By temporarily stopping the supply of purified water to the hydrogen gas, hydrogen gas can be more efficiently dissolved in the deaerated water, and hydrogen water having a high concentration of dissolved hydrogen gas can be produced. Specifically, the hydrogen-dissolved concentration, which is usually about 1.6 ppm at room temperature and atmospheric pressure, can be increased to about twice.

The hydrogen water produced in this way is mixed with the aforementioned functional raw material to obtain the hydrogen-containing beverage of the present invention. Moreover, when the functional raw material is already melt | dissolved in the water used as a raw material, the hydrogen containing drink of this invention can be obtained by passing through a process (d).
In addition, the hydrogen-containing drink containing a functional raw material is filled in a sealed container after production, and is heat-sterilized as desired.
The sealed container is not particularly limited, and examples thereof include a bag-like container made of a laminate film, a metal can, and the like. Particularly, a bag-like container made of an aluminum laminate film is highly airtight and prevents hydrogen from flowing out. Is preferable. The bag-like container may be provided with a plastic mouthpiece (spout) or the like. And using the filling apparatus according to the kind of the said sealed container, hydrogen containing water is filled into a sealed container, and it seals.
Moreover, the hydrogen-containing drink with which the sealed container was filled can heat-sterilize a water product between 85-90 degreeC and 20 minutes-1 hour, for example using a heating steam sterilizer.

  Preferred embodiments of the present invention will be described more specifically, but the present invention is not limited thereto.
