Description

  The present invention relates to concentrated mineral water or mineral water powder.

  As the quality of tap water deteriorates nationwide, demand for mineral water is increasing. Mineral water is not only delicious, but it may contain many essential trace elements that are essential for maintaining human health, depending on the production area.

  On the other hand, seawater, particularly deep seawater, is rich in various ionic components, and raw water or seawater that has been subjected to various treatments is widely used in foods, pharmaceuticals, cosmetics, agriculture, fisheries, and the like.

  Incidentally, Table 1 below shows an example of analysis results of ocean surface water and ocean deep water. Deep water is characterized by low temperature, low viable count, and high nutrients. There is no significant difference between surface water and deep water for various ions.

Various methods for obtaining mineral water (water) from the deep ocean water have been proposed as follows.
JP-A-9-290260 JP 2001-87762 A JP 2003-94055 A

  In Patent Document 1, salt water is separated into permeated water and concentrated seawater by a reverse osmosis membrane, concentrated seawater is separated into concentrated seawater and demineralized water by an electrodialysis method, and evaporated water and reverse osmosis obtained by evaporating water from the concentrated seawater. It is the manufacturing method of the drinking water which supplies the permeated water of a membrane as drinking water.

  Patent Document 2 is a method for producing water in which deep sea water is desalted by reverse osmosis to produce desalted water, and the deep sea water is desalted by electrodialysis using the desalted water.

  Patent Document 3 discloses a desalination process in which seawater is desalted to produce desalted treated water and concentrated seawater, and salt is separated from the concentrated seawater generated in the process to obtain concentrated mineral water. Dilute mineral water by measuring the conductivity of the concentrated mineral water generated in the concentrated mineral water generating step and the concentrated mineral water generated in the desalted water generated in the desalting step. It is the mineral composition which consists of the mineral water production | generation process to produce | generate, its manufacturing method, and its usage method.

  In this way, seawater can be used as mineral water (water), and it balances nutrient elements such as calcium and magnesium, nitrogen and phosphorus, and trace elements such as selenium, zinc, manganese and iodine. Although technology that can produce mineral water rich in minerals that are often contained has been proposed, the produced mineral water (water) is distributed as it is, and transportability is inefficient. It was typical.

  In addition, even though mineral water (water) contains a lot of essential trace elements that are indispensable for maintaining human health, the content in 1 liter is at most about 50 to 100 micrograms, The effect is weak unless you drink a lot of water.

  Therefore, it has been studied to use mineral water by concentrating the mineral water and increasing the concentration of the mineral content.

  For example, in Patent Document 3, mineral paste or mineral powder, mineral water, mineral paste and / or mineral powder obtained by concentrating or drying mineral water are used as beverages, powdered beverages, processed foods, tofu. Reference is made to a method for producing a processed product containing a mineral composition, characterized in that it is added to a raw material of a coagulant, a skin external preparation water, a plant growth regulator or an animal growth regulator.

  In paragraph [0033] of the specification of Patent Document 3, “In the present invention, both the treated raw water and dialysis water are ionic water having a specific composition, and therefore both can be used as products. The obtained ionic water may be further used as a mineral paste or mineral powder by performing operations such as concentration, solidification, and drying. ”However, a specific method of concentration and solidification is shown. Not.

  In a normal concentration method using a dialyzer, concentration by changing the ratio of salt concentration is possible, but there is a problem that a large amount of mineral content is lost.

  Further, when the water is concentrated by evaporating the water, for example, in the case of mineral water containing sulfate ions such as deep sea water, minerals contained in the mineral water, especially alkaline earth metals such as Mg and Ca, are sulfate ions. It binds to form an insoluble precipitate. When precipitates are generated in this way, the precipitates are not redissolved, resulting in a problem that the mineral content in the mineral water is reduced.

  In addition, when an insoluble precipitate is generated, the following problems also occur. That is, if the concentrated mineral water is dried with a spray dryer to form a powder, handling becomes easier and the convenience of transportation increases. However, if there is a precipitate in the concentrated mineral water, the spray dryer will be clogged. In order to prevent this, even if the precipitate was removed before drying, there was a problem that the tube was clogged due to concentration in the nozzle or the administrer due to concentration.

  The object of the present invention is to eliminate the inconvenience of the conventional example, and the mineral water contained in the mineral water can be concentrated and powdered in the same uniform component state without generating an insoluble precipitate. And providing the powder.

  To achieve the above object, the mineral water of the present invention is firstly concentrated by adding an amino acid to mineral water containing at least either magnesium or calcium, and secondly, 1 mol of mineral content contained in the mineral water. On the other hand, the gist is that 0.1 mol or more of amino acid is added and concentrated, and thirdly, the amino acid is glycine.

  The fourth aspect is that the mineral water containing at least either magnesium or calcium is deep ocean water.

  Further, as mineral water powder, amino acid and syrup or reduced syrup are added to mineral water containing at least either magnesium or calcium, concentrated, and then dried by a spray dryer or a known method to be powdered. This is the gist.

  According to the first aspect of the present invention, a chelate compound is formed by a metal ion, which is a mineral component in mineral water, and an amino acid, and the metal ion is trapped between chelate rings by amino acid molecules. Even if it does not produce | generate an insoluble precipitate by the sulfate ion in mineral water, it can concentrate in the uniform component state as it is.

  According to this invention of Claim 2, in addition to the said effect | action, the danger that a deposit will be produced by subsequent concentration by making the amino acid added with respect to 1 mol of minerals contained in mineral water 0.1 mol or more. Can be avoided sufficiently.

  As amino acids, valine, leucine, isoleucine, alanine, arginine, glutamine, lysine, aspartic acid, glutamic acid, proline, cysteine, threonine, methionine, histidine, phenylalanine, tyrosine, tryptophan, asparagine, glycine, serine can be used. However, according to the present invention described in claim 3, glycine having the simplest structure and the smallest molecular weight is most suitable in terms of molecular weight and molecular shape.

  According to the present invention of claim 4, the deep ocean where the number of viable bacteria is small and the amount of nutrients is high, while overcoming the weakness of deep ocean water that insoluble precipitation is likely to occur due to minerals and sulfate ions when dry concentrated. Mineral water can be obtained taking advantage of water.

  According to the present invention of claim 5, a chelate compound is formed by a metal ion that is a mineral content in mineral water and an amino acid, and the metal ion is trapped between chelate rings by amino acid molecules. Even so, insoluble precipitates are not generated by sulfate ions in mineral water. Therefore, even if concentrated mineral water is dried with a spray dryer, the spray dryer nozzles do not clog sediment, or the mineral content solidifies inside the spray dryer and remains in a uniform state. Is obtained. Moreover, it becomes a fine powder form by the added water candy or reduced water candy.

  As described above, according to the mineral water and the powder thereof of the present invention, the mineral contained in the mineral water is concentrated and powdered in a uniform component state as it is without forming an insoluble precipitate. it can.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a production process diagram showing a first embodiment of mineral water and powder thereof according to the present invention, FIG. 2 is a production process diagram showing a second embodiment of the same, and FIG. 1 is a diagram when deep sea mineral water is used. 2 is a case where deep sea mineral water is used.

  As shown in FIG. 1, the present invention adds an amino acid to deep sea mineral water or deep sea mineral salt water as mineral water containing at least one of magnesium and calcium (and often includes both) and mixes at 55 ° C. Concentrate with a concentrator (solid content 25%).

  When the mineral water is obtained from seawater, FIG. 3 shows how to obtain raw water, deep ocean mineral water, deep ocean mineral salt water, and salt water.

  As shown in FIG. 3, the deep ocean water 26 is pumped up by a water intake pump 37a in a water intake pump chamber 37 through a water pipe 36 and sent to a primary storage tank 38. Then, this water is further treated as water to be treated by a water supply pump 38a. Send to each processing line. A plurality of types of water such as raw water 21, mineral water 208, salt water 209, fresh water 18, and mineral salt water 19 can be obtained depending on the manner of treatment.

  First, a method for obtaining the fresh water 18 and the mineral salt water 19 will be described. The RO membrane separation device 13 provided with a reverse osmosis membrane (hereinafter referred to as RO membrane) is provided.

  In the RO membrane separator 13, as the RO membrane, for example, a cellulose acetate membrane, a synthetic polymer membrane (polyvinyl, crosslinked aramid, crosslinked polyamide, etc.) can be used. Various RO membranes such as a hollow fiber type and a spiral type can be used, and it is convenient to use a module shape.

  The water is stored in the water supply tank 39 and sent to each water supply stand 28 by a water supply pump 39a as necessary. When not taken out from the water supply stand 28, it is circulated and periodically sterilized by the UV sterilizer 29. .

  The RO membrane separation device 13 supplies the RO membrane to remove solutes such as salts in the water 17 by membrane separation, and the water that has permeated the RO membrane and reduced these solutes is fresh water (permeated water) 18. As a mineral salt water (non-permeated water) 19, water obtained by concentrating these solutes without passing through the RO membrane is obtained.

  Next, a method for obtaining the mineral water 208 and the salt water 209 will be described. The raw water produced by applying the electrodialyzer 203 and containing a large amount of the diluted mineral is the mineral water 208, and the concentrated water is the salt water 209.

  The electrodialyzer 203 is composed of a room partitioned by an ion exchange membrane, and the ion exchange membrane includes a cation membrane that selectively transmits only cations and an anion membrane that selectively transmits only anions. Are assembled alternately. In the present invention, sodium ions and chlorine ions are desalted as much as possible from seawater passing through the electrodialyzer 203 so that useful minerals such as potassium, calcium and magnesium remain as much as possible without desalting. preferable. However, there is no cation membrane that does not allow permeation of desired metal ions such as potassium, calcium, magnesium and the like. Therefore, a monovalent ion selective membrane is used as the cation membrane. As a result, monovalent ions such as sodium, potassium, and chlorine ions are selectively removed from seawater and the like, and most of the ions existing in the raw water remain without removing divalent or higher ions.

  As such a monovalent ion selective membrane used in the electrodialyzer 203, for example, product number k-192 manufactured by Astom Co., Ltd. can be mentioned. Moreover, as an anion exchange membrane (anion membrane), arbitrary things can be used, For example, product number A-501 by Astom Co., Ltd. can be mentioned.

  The electrodialysis apparatus 203 can adjust the desalination utilization rate appropriately to adjust the mineral content in the demonovalent ionized water 207 as desired.

  In addition, the raw | natural water 21 as it is can also be obtained, without obtaining the above processes. Each type of water obtained in this way is temporarily stored in the water supply tank 39 and sent out to the respective water supply stands 28 by the water supply pump 39a as necessary, and is circulated when not taken out from the water supply stand 28. The UV sterilizer 29 is used to sterilize regularly.

  Of these various types of water, mineral water 208 containing a large amount of minerals and mineral salt water 19 (hereinafter, deep sea mineral water 20) are concentrated as shown in FIGS.

  As shown in FIG. 1, glycine 30 as an amino acid is added to the kneader 32 at a ratio of 70.00 (kg) as the amino acid to the deep sea mineral water 20 with respect to 10,000,000 (kg). Then, the mixture is dried with a circulating vacuum concentrator 33 at an evaporation amount of about 800 L / H and concentrated. During concentration, the liquid temperature rises to 60-70 ° C.

  When the final liquid amount becomes small and cannot be concentrated by the circulation type vacuum concentrator 33, the final concentration is performed by the 1000 L vacuum concentrator 34. After that, those concentrated by drying with these dryers are sterilized, superheated and stirred at 85 ° C. for 10 minutes, passed through a 60 mesh sieve to remove foreign matters, and concentrated mineral water 22 is obtained.

  The concentrated mineral water 22 thus obtained contains the components of the deep sea mineral water 20 as it is, and also contains Mg and Ca, which are particularly useful for the human body, without damaging the precipitate as a precipitate. .

  Glycine has the simplest structure and has the smallest molecular weight, and is a preferred amino acid. However, as an amino acid, instead of glycine, valine, leucine, isoleucine, alanine, arginine, glutamine, lysine, aspartic acid, glutamic acid Proline, cysteine, threonine, methionine, histidine, phenylalanine, tyrosine, tryptophan, asparagine, glycine, serine and the like can also be used.

  In the case of the mineral salt water 19, as shown in FIG. 2, the mineral salt water 19 is added as an amino acid to the kneader 32 at a ratio of 100.00 (kg) as an amino acid to the 5.000.00 (kg), As described above, the mixture is mixed at 55 ° C., dried by the circulating vacuum concentrator 33 at an evaporation amount of about 800 L / H, and concentrated. During concentration, the liquid temperature rises to 60-70 ° C.

  When the final liquid amount becomes small and cannot be concentrated by the circulation type vacuum concentrator 33, the final concentration is performed by the 1000 L vacuum concentrator 34. After that, those concentrated by drying with these dryers are sterilized, heated and stirred at 85 ° C. for 10 minutes, passed through a 60-mesh sieve to remove foreign substances, and concentrated mineral brine 22 ′ is obtained.

  In addition, when further powdered, the above-mentioned deep sea mineral water 20 is added to 100000.00 (kg) as an amino acid with glycine 30 added at a ratio of 70.00 (kg), and then syrup or reduced. Add water candy 31 (trade name PO-10 is preferred as reduced water candy) at a rate of 160.00 (kg), mix at 55 ° C. as described above, and circulate vacuum concentrator 33 and 1000 L vacuum concentrated. What was concentrated until the sugar concentration was Bx = 25 by drying with a machine 34 was sterilized, heated and stirred at 85 ° C. for 10 minutes, passed through a 60 mesh sieve, and then removed with a spray dryer 35 Dry with a 20 mesh sieve and pass through magnet path. Thereby, powdered mineral water 27 is obtained.

  Alternatively, mineral salt water 19 is added as an amino acid to 5.000.00 (kg) and glycine 30 is added at a ratio of 100.00 (kg). 10 is preferred) at a rate of 115.00 (kg), mixed at 55 ° C. as described above, and concentrated by drying with a circulating vacuum concentrator 33 and a 1000 L vacuum concentrator 34 The mixture is sterilized, heated and stirred at 85 ° C. for 10 minutes, passed through a 60-mesh sieve, and after removing foreign matter, dried by a spray dryer 35, passed through a 20-mesh sieve, and passed through a magnet path. Thereby, powder mineral salt water 27 'is obtained.
