Description

The invention relates to the field of water preparation, and more particularly to artificially mineralized drinking water, a composition for its preparation and a method for its preparation from distilled water, and can be used in the food industry and other fields for producing balanced drinking water.

It is known that the quality of drinking water is regulated by state standards. So, in the Russian Federation, the quality of drinking water is regulated by GOST “Drinking Water” (No. 2874-82).

In addition, it is known that distilled water has the best taste properties, the use of such water in moderation in the opinion of doctors and nutritionists improves the quality of life.

However, distilled water does not meet the criterion of physiological usefulness established for drinking water, since it does not contain biologically necessary macro- and microcomponents.

Known artificially mineralized water prepared from distilled water and containing 20-40 mg / l of strontium ions, 50-100 mg / l of calcium ions and 0.06-0.15 mg / l of lithium ions, as well as sulfates, chlorides and nitrates ( Patent DE 3201405, 1983). A disadvantage of water is its limited physiological value.

Known drinking water obtained from distillate (AS USSR No. 407840, 1973), containing desalinated sea water mixed with a mineralizing additive, which is used as a clarified waste brine in the amount of 1-2% of the total volume of drinking water. The disadvantage of drinking water obtained by the method described in A.S. USSR No. 407840, is that this water contains mainly only chlorine and sodium ions, the accumulation of which in the human body leads to edema and increased blood pressure.

Known water obtained in accordance with TU 6-09-3457-83. "A set of salts for the preparation of drinking water from a distillate", according to which 5 tons of distillate are introduced, g: sodium sulfate 480; magnesium sulfate, 7-aqueous 406; calcium chloride crystal 1610; sodium bicarbonate 1313; sodium fluoride 9.

From the given salt composition introduced into the distillate according to TU, it follows that an increased content of calcium ions is formed in water, in addition, a large amount of sodium ions is additionally introduced. It is known that calcium and magnesium are antagonists and practically "lock" each other in the body, therefore, there is a significant decrease in the excretion of these elements from the body, calcium is deposited in the form of salts in organs and joints.

A common feature among the above analogues is the mixing of distilled water with mineralizing additives.

A known method of producing drinking water from distilled by introducing potassium sulfate and magnesium sulfate (RF patent No. 2051125, 1995). In this way, water is obtained physiologically balanced in potassium and magnesium salts. The qualitative and quantitative salt composition introduced into the distillate described in the patent of the Russian Federation No. 2051125 makes it possible to obtain water that is easily absorbed by the body, as well as with an increased ability to wash waste products out of it, however, it is impossible to use such water for such a long time due to the absence of such physiologically necessary ions, like calcium ions.

Known artificially mineralized drinking water and a composition for its preparation (RF patent No. 2134241, 1999), which includes at least one compound of calcium, magnesium and iodine, the concentration of which in terms of calcium, magnesium and iodine is 20 -150, 8-120 and 0.01-0.15 mg / L. In the particular case of performing the compound of calcium and magnesium is selected from water-soluble sulfates and / or citrates. Additionally, the water contains at least one potassium compound, one zinc compound and one manganese compound.

Despite the fact that the artificially mineralized drinking water described in the patent of the Russian Federation No. 2134241 is not prepared from distilled water, according to the set of essential features, the artificially mineralized water and the composition for its preparation are the closest analogue to these objects, since it contains sulfates and / or calcium and magnesium citrates, as well as potassium, zinc and manganese compounds. The disadvantages of artificially mineralized drinking water and the composition of the prototype (RF patent No. 2134241) should not include the full compliance of its composition with the physiological needs of the body.

The closest analogue to the method for producing artificially mineralized water of the proposed composition is a known method for the mineralization of drinking water from a distillate (Ukrainian patent No. 17513, 2006), including the introduction of magnesium sulfate in the distillate in an amount of 24-30 mg / l (in terms of Mg ion ²⁺ ), potassium sulfate - 80 ÷ 100 mg / l (in terms of K ⁺ ion), zinc sulfate - 2.0 ÷ 4.5 mg / l (in terms of Zn ^{2+ ion} ), manganese sulfate - 0, 04 ÷ 0.09 mg / l (in terms of Mn ^{2+ ion} ) and subsequent exposure, which is carried out for 1.5 ÷ 2.0 hours. The disadvantages of mineralized drinking water obtained according to the method described in the patent of Ukraine No. 17513, is that the ratio of ingredients is not completely balanced due to the lack of calcium salts.

The present invention has set and solved the problem of obtaining artificially mineralized drinking water enriched with mineral additives in a balanced form from distilled water.

The technical result of the proposed technical solution is to obtain artificially mineralized drinking water from distilled water enriched with mineral additives in a balanced form by ensuring that its composition matches the physiological needs of the body.

To solve the problem and achieve the specified result, a group of inventions is proposed, united by a common inventive concept.

One aspect of the proposed group of inventions is artificially mineralized drinking water containing distilled water and water-soluble magnesium compounds in the form of magnesium sulfate, calcium in the form of calcium citrate, potassium, zinc and manganese compounds, while magnesium sulfate is contained in an amount of 24 ÷ 30 mg / l (in terms of Mg ^{2+ ion} ), calcium citrate - 4 ÷ 6 mg / l (in terms of Ca ^{2+ ion} ), potassium compounds in the form of potassium sulfate - 80 ÷ 100 mg / l (in terms of K ⁺ ) zinc compound in the form of zinc sulfate - 2 ÷ 4,5 mg / l (calculated as Zn ²⁺ ion) cos Inonii manganese as manganese sulfate - 0.04 ÷ 0.09 mg / l (based on the Mn ²⁺ ion).

Unlike the prototype, the proposed artificially mineralized drinking water contains distilled water, as well as mineralizing additives in the selected quantitative value: magnesium sulfate in an amount of 24 ÷ 30 mg / l (in terms of Mg ^{2+ ion} ), calcium citrate - 4 ÷ 6 mg / l (in terms of Ca ^{2+ ion} ), potassium compounds in the form of potassium sulfate - 80 ÷ 100 mg / l (in terms of K ⁺ ion), zinc compounds in the form of zinc sulfate - 2 ÷ 4.5 mg / l (in in terms of Zn ^{2+ ion} ), manganese compounds in the form of manganese sulfate - 0.04 ÷ 0.09 mg / l (in terms of Mn ^{2+ ion} ).

According to the invention, introduced in distilled water, calcium citrate in a selected quantitative value (4 ÷ 6 mg per liter of water), while not being an antagonist of manganese, magnesium and zinc (in their chosen quantitative values), contributes to the full assimilation of all these elements by the body and to replenish the required minimum calcium , which should be in the human body, and, thus, ensures that the composition of water matches the physiological needs of the body.

Another aspect of the invention is a composition for the preparation of artificially mineralized drinking water based on compounds soluble in distilled water - magnesium sulfate, calcium citrate, potassium sulfate, zinc sulfate and manganese sulfate, while the mass ratio of magnesium: potassium: zinc: manganese: calcium is, respectively: 385.7: 1285.7: 50: 1: 71.4.

The proposed qualitative and quantitative salt composition, introduced into distilled water, allows to obtain artificially mineralized drinking water enriched with mineral additives in a balanced form.

The next aspect of the invention relates to a method for producing artificially mineralized drinking water from a distillate, which comprises introducing magnesium sulfate in an amount of 24 ÷ 30 mg / l (in terms of Mg ^{2+ ion} ), potassium sulfate - 80 ÷ 100 mg / l (in terms of K ⁺ ion), manganese sulfate - 0.04 ÷ 0.09 mg / l (in terms of Mn ^{2+ ion} ), zinc sulfate - 2 ÷ 4.5 mg / l (in terms of Zn ^{2+ ion} ) and citrate calcium in an amount of 4 ÷ 6 mg / l (in terms of Ca ^{2+ ion} ), followed by exposure for at least 3 hours.

The proposed method includes such essential features as the introduction into distilled water in a certain concentration of magnesium sulfate, potassium sulfate, zinc sulfate and manganese sulfate, while in contrast to the prototype, calcium citrate is introduced in distilled water in an amount of 4 ÷ 6 mg / l, and the extract mineralized water is carried out for at least three hours.

The advantages of the proposed solution are to improve the quality of water by achieving its balance in ions of magnesium, potassium, manganese, calcium, since the declared quantitative ratios of calcium and magnesium (1: 6), as well as calcium and magnesium (1: 22.5) are close to the optimal ratio. The balanced composition of water improves physiological and technological requirements, since water thus prepared is low salinity (pH 6.0), which allows storing water for an unlimited time, while during the entire storage time the water does not lose its full physiological value.

The possibility of objective manifestation of the technical result when using the invention is confirmed by reliable data given in the examples illustrating the invention, including example 1, which describes a method for producing artificially mineralized drinking water of the proposed composition, as well as example 2, containing experimental information obtained as a result of research.

The invention is illustrated in tables.

Table 1 presents the physicochemical characteristics of water.

Table 2 presents the organoleptic characteristics of water.

The method is as follows.

Pre-dissolved in a small amount of distilled water separately potassium sulfate, magnesium sulfate, zinc sulfate, manganese sulfate, calcium citrate. For these purposes, only salts of qualification “h”, “hch” and “chda” are suitable, and calcium crystalline citrate is food grade according to TU 9199-001-01014470-96.

Then, a predetermined amount of distilled water is poured into a large chemically neutral container, after which previously prepared salt solutions are introduced into it successively with slow stirring. The order of administration does not matter. The resulting mineralized water is mixed and left for three hours, additionally mixing water every 30 minutes, after which it is poured into the required container.

Example 1

amount (mg / l): 27: 90: 3,5: 0,07: 5,

ion ratio calculated by the average value of each element: 385.7: 1285.7: 50: 1: 71.4.

To obtain 1000 l of artificially mineralized water, according to the method, 940 l of distillate is taken and 124 g of magnesium sulfate 7 - aqueous, 200 g of potassium sulfate, also dissolved in 20 l of distillate, 10 g of zinc sulfate dissolved in 5 l of distillate, 250 mg of manganese sulfate dissolved in 5 l of distillate, and 19 g of calcium citrate dissolved in 5 l of distillate. The artificially mineralized water thus obtained is thoroughly mixed and aged for at least 3 hours, additionally mixing the water every 30 minutes so that the salts dissolve in full.

Analysis of artificially mineralized water obtained in this way confirmed the following ionic composition: magnesium sulfate in an amount of 27 mg / l (in terms of Mg ^{2+ ion} ), potassium sulfate - 90 mg / l (in terms of K ⁺ ion), zinc sulfate - 3.5 mg / l (in terms of Zn ^{2+ ion} ), manganese sulfate - 0.07 mg / l (in terms of Mn ^{2+ ion} ), calcium citrate - 5 mg / l (in terms of Ca ² ion ⁺ ), as well as the physicochemical characteristics given in table 1.

As can be seen from Table 1, the water obtained according to the accepted classification is weakly mineralized with a low sulfate content, which confirms the attached expert opinion No. 39 / 07-1458 of 03/17/2009.

Organoleptic and taste qualities of the resulting water are shown in table 2.

The organoleptic and taste qualities of the water obtained are satisfactory, which confirms the attached expert opinion No. 39 / 07-1458 of 03/17/2009.

Example 2

To confirm the optimal amount of calcium in the water obtained according to example 1, experiments were conducted on 15 white outbred rats weighing 120-150 g. According to the purpose of the experiment, the rats were divided into 3 groups of 5 rats each.

Methods: during the whole life of rats, starting from the 3rd week of life, rats received water of a certain following composition:

a) group 1: water with no calcium in it (water composition for this group of rats: magnesium sulfate 24-30 mg / l (in terms of Mg ^{2+ ion} ), potassium sulfate 80-100 mg / l (in terms of ion K ⁺ ), zinc sulfate 2.0-4.5 mg / l (in terms of Zn ^{2+ ion} ), manganese sulfate 0.04-0.09 mg / l (in terms of Mn ^{2+ ion} )) and, with a low calcium content in animal feed;

b) group 2: water with the addition to the composition specified in paragraph "a" of an excess amount of calcium citrate (60 mg / l (in terms of Ca ^{2+ ion} ));

c) group 3: water with the addition to the composition specified in paragraph "a" of calcium citrate in an amount of 4-6 mg / l (in terms of Ca ^{2+ ion} ).

The results of the study:

a) group 1, which received water with no calcium in it: rat hair became rare. Rats lived on average about 2 years;

b) group 2, which received water with excess calcium content: the life expectancy of rats was reduced on average to 1 year due to impaired cardiovascular activity (calcification of large vessels of the heart);

c) group 3, which received water of magnesium sulfate 24-30 mg / l (in terms of Mg ^{2+ ion} ), potassium sulfate 80-100 mg / l (in terms of K ⁺ ion), zinc sulfate 2.0-4 , 5 mg / l (in terms of Zn ^{2+ ion} ), manganese sulfate 0.04-0.09 mg / l (in terms of Mn ^{2+ ion} ), calcium citrate 4-6 mg / l (in terms of ion Ca ²⁺ ): the life expectancy of rats of this experimental group averaged about 3 years, with 2 of 5 rats living more than 3 years. The appearance of rats (hair) is normal.

Thus, the artificially mineralized drinking water obtained according to the invention, enriched with mineral additives in a balanced form, corresponds in its composition to the physiological needs of the body, is low-mineralized (pH 6.0), which allows storing water for virtually unlimited time, while during the entire storage time water does not lose its full physiological value.
