Description

[Detailed description of the invention]

The present invention relates to alkaline ion ice and a method for producing the same, and more particularly to alkali ion-containing water whose PH value does not change even after long-term storage and a method for producing the same. In recent years, water containing alkali ions obtained by electrolyzing water in which minerals are dissolved is called alkaline ion water or calcium ion water, and various devices for obtaining water containing alkali ions have been commercially available. Although the medical effects of this alkaline ionized water have not been clarified in principle, its drinking effects are attracting attention. However, after a few days, alkaline ionized water
The PH value has decreased, and even if you try to store it in the refrigerator and drink it as cold water, the alkaline ion concentration has already decreased and no effect can be expected. The present invention provides alkali ion ice in which the alkali ion components are preserved semi-permanently, the pH value does not decrease over a long period of time, the taste is excellent, and the ice is transparent and crack-free, as well as a method for producing the same. With the goal. The alkali ion ice of the present invention contains alkali ions consisting of calcium ions, potassium ions, and sodium ions, and the concentration of calcium ions is 30 to 80 ppm, and the concentration of potassium ions is 10
30ppm to 30ppm, sodium ion concentration 10 to 30ppm
It is characterized by having a pH of 8.0 to 10.5 in the range of 30 ppm. Furthermore, the method for producing alkali ion ice of the present invention includes:
Calcium ions are 30 to 80 ppm in raw water,
Adjust the ion concentration so that it contains 10 to 30 ppm of sodium ions, and add potassium at a concentration of 20 to 50 ppm to prepare an aqueous alkali ion raw material solution.
The method is characterized in that a direct current of 100 amperes is applied to obtain an alkali ion aqueous solution having a pH value in the range of 8.0 to 10.5, and ice is produced by freezing the alkali ion aqueous solution having a pH value in the range. The present invention will be explained in more detail. The alkali ion ice of the present invention contains calcium ions, potassium ions, and sodium ions as alkali ions. In addition to playing an important role as a component of bones and teeth, calcium ions have various functions such as cell activation, muscle contraction, and nerve stimulation.
It has been found that hormonal secretion is subtly regulated by maintaining a constant value within the mg/dl range. Therefore,
Calcium ions are an essential component of the alkaline ion ice of the present invention, and calcium ions are considered to be the main factor in the drinking effect. The content of calcium ions is 30 to 30% compared to the alkali ion ice of the present invention.
Must be in the 80ppm range. The content is
If it is less than 30 ppm, it will not be effective, and if it exceeds 80 ppm, calcium ions will be excessive and there will be a risk of precipitation, the transparency will decrease, and cracks may occur, so it cannot be used. Potassium ions help raise the pH value and help eliminate cholesterol from the body. The content of potassium ions should be in the range of 10 to 30 ppm for the alkali ion ice of the present invention. If it is less than 10ppm, it will not have the effect of increasing the PH value,
Moreover, if it exceeds 30ppm, it will have a negative effect on taste. Sodium ions are included in order to impart so-called roundness to the taste of the alkali ion ice of the present invention and to assist in increasing the pH value. The content of sodium ions is higher than that of the alkali ion ice of the present invention.
The range is 10 to 30 ppm. At 10 ppm, there is no change in taste, while at more than 30 ppm, the salty taste becomes strong and undesirable. In addition to the above-mentioned alkali ions, for example, even if magnesium ions, chloride ions, etc. are present, there is no particular problem as long as the content thereof is about 10 ppm or less. In producing the alkali ion ice of the present invention, the calcium ion concentration in the raw water is 30 to 30.
Adjust the sodium ion concentration to 80ppm and 10 to 30ppm. Depending on the quality of the raw material water to be used, if calcium ions and sodium ions are present in excess, they cannot be used; on the other hand, if only a small amount is present, necessary treatment is performed. That is, when calcium ions are insufficient, calcium chloride and/or an acid-treated animal bone solution is added. Calcium chloride may be dissolved in a predetermined amount of water in advance and this aqueous solution may be added to the raw water, or it may be directly added to the raw water, mixed and stirred, and dissolved. As the acid-treated solution for animal bones, for example, an acid-treated solution obtained by treating the bones of birds or fish with an acid such as hydrochloric acid, lactic acid, or acetic acid to extract the calcium content can be used. If sodium ions are insufficient, add salt. Salt may be dissolved in a predetermined amount of water and this aqueous solution may be added to the raw water, or it may be directly added to the raw water and mixed and stirred to dissolve. Next, 20 to 50 ppm of potassium chloride is added to the raw water to prepare the alkaline ion raw water of the present invention. Potassium chloride may be prepared in advance as an aqueous solution and added to the raw water, or may be added directly. In either case, the potassium ion concentration in the raw water is between 10 and 10.
Add the above amount of potassium chloride to give a concentration of 30 ppm. Potassium chloride does not necessarily need to be added after adjusting the amount of calcium ions and/or sodium ions, and may be added to the raw water first. Furthermore, depending on the quality of the water, it may not be necessary to adjust the amount of calcium ions and/or sodium ions, so in this case, sodium chloride is added immediately. The alkali ion raw material water obtained as described above is then electrolyzed to obtain an aqueous alkali ion solution.
In electrolysis, an electrolytic cell is partitioned into two sections by an ion-permeable membrane, an anode is inserted into one section and a cathode is inserted into the other section, and a direct current higher than the decomposition voltage is passed between the electrodes. The amount of current is 10 to 100 amperes per ton of alkaline ion raw water, and the cathode side has a pH of 8.0 to 100 amperes.
An aqueous alkali ion solution with a range of 10.5 is obtained.
It is also possible to adjust the alkali ion concentration by supplying electricity while measuring the alkali ion concentration and then stopping the supply of electricity within the above-mentioned predetermined value range. Next, the alkali ion aqueous solution thus obtained is frozen to make ice. Ice is usually made between -8° and -
This can be done by immersing a container containing the aqueous solution in brine at 15°C for 1 to 2 days and freezing, but the ice making method is not necessarily limited to this method, and the ice making temperature and time may also vary. It's not critical. With the development of a new continuous ice making device, it is now possible to make ice from alkaline ionized water continuously without changing the component composition. The alkali ion ice of the present invention does not cause a decrease in alkali ion concentration over a long period of time, has excellent ice quality and taste, does not crack, and is good for health by alkalizing body fluids, and can be used as a diluent in Western liquor. It is also effective in preventing hangovers. Next, embodiments of the present invention will be described. Example Using tap water as raw material water, the concentration of contained ions and pH were measured, and the results were as follows.

It was adjusted to be 65.7ppm, 20.9ppm, and 26.0ppm. Next, raw water was poured into the cathode side of an electrolytic cell (trade name "Mini Pot M-1 type" manufactured by Omco Co., Ltd.), and tap water was poured into the anode side.Electricity was applied at 340 mA for 15 minutes, and the cathode An aqueous alkali ion solution of No. 1 was obtained from the side. When the alkali ion concentration in this solution was measured, it contained 58 ppm of calcium ions, 20 ppm of sodium ions, and 26 ppm of potassium ions, and the pH was 10.3. An aqueous solution of 0.8 alkali ions was placed in a freezer maintained at a temperature of -30°C and ice was made for 15 hours while applying vibrations.The alkaline ice of the present invention thus obtained is highly transparent and has a taste unique to alkaline ionized water. was observed, and no cracks were observed.The PH value decreased during ice making.
