Description

The invention relates to the field of food industry, in particular to a new composition of an antioxidant composition for improving the quality of drinking water. An antioxidant composition consisting of a mixture of dihydroquercetin and glucose in a ratio of 1: 1 in drinking water can prevent the development of free radical processes and disorders of the antioxidant system of the body.

It has now been proven that antioxidants in foods, drinks and dietary supplements can prevent oxidative stress and prevent the development of certain diseases (cancer, diseases of the cardiovascular system).

Vitamins A, B, C and E, coenzyme Q10 and dihydroquercetin are considered effective antioxidants. The strongest of all antioxidants is dihydroquercetin (vitamin P), which is found more in plants. It is a reference antioxidant, tens of thousands of times superior in activity to antioxidants such as vitamins A, C and E.

Figure 1 presents the structural formula of dihydroquercetin.

The object of study is water, because it is one of the most important components of everyday consumption for humans and has a significant impact on the state of the body. As an auxiliary component for the development of the composition of the antioxidant composition to improve the quality of drinking water, glucose is selected.

Figure 2 presents the structural formula of glucose.

Thus, the development of antioxidant compositions to improve the quality of drinking water is important.

Currently, from the antioxidant compositions of water, the invention is known - "A beverage composition containing CLA" (RF patent 2491837, publ. 09/10/2013). In this invention, the beverage composition contains fat, which includes at least 40 wt.% Conjugated linoleic acid (CLA) in the form of triglyceride, protein from 2 to 8 wt.%, A thickener and an aqueous phase. Conjugated linoleic acid (CLA) acts as an antioxidant. The invention describes a scheme for the isolation of CLA from a fat emulsion of vegetable origin. However, the disadvantage of the invention is the lack of recommendations for the use of the composition of the drink, and not specified a method for assessing the antioxidant activity of the specified composition.

A known method of producing antioxidant water for cleaning the body (RF patent 2297982, publ. 04/27/2007). The invention relates to the field of chemistry, in particular to a method for producing antioxidant healing water of natural origin - antioxidant melt glacial water to cleanse the body of toxins. To obtain antioxidant water, melt water is taken at the foot of glaciers located at an altitude of 3-4 km above sea level and 0.04-0.05% hydrogen peroxide of the total volume of selected glacial melt is added to it. The disadvantage of the invention is that the improvement of medicinal properties and water quality is not associated with the presence of antioxidants in it. In addition, the invention does not indicate a method for evaluating the antioxidant activity of water.

A new technical challenge is to develop an effective composition of an antioxidant composition containing natural antioxidants to improve the quality of drinking water.

The problem is achieved in that in order to obtain an effective composition of the antioxidant composition, drinking water is selected and saturated with a mixture of dihydroquercetin and glucose in a ratio of 1: 1 by dissolution. For this, 1 mg of dihydroquercetin and glucose are dissolved in 1 liter of drinking water at room temperature (25 ° C).

To assess the effective composition of the antioxidant composition of drinking water, the method of cathodic voltammetry was used, which allows one to measure the antioxidant activity of water containing antioxidants. To evaluate the antioxidant activity of water by voltammetry, we used the process of electroreduction of oxygen (EV O ₂ ) in the absence and in the presence of an antioxidant in solution from the time of action on EV O ₂ . According to the results obtained, the coefficient of antioxidant activity was calculated according to the kinetic criterion (K, μmol / l min) for the test sample. The methodology for calculating the coefficient of antioxidant activity according to the kinetic criterion is presented in the article - E.I. Korotkova, Yu.A. Karbainov, O.A. Avramchik. Voltammetric determination of antioxidant activity of plant materials and some food products // Izv. universities. Chemistry and Chem. technology. 2002, Vol. 45, No. 3, pp. 110-112.

To confirm the development of an effective composition of the antioxidant composition for improving the quality of water, consisting of dihydroquercetin and glucose in a ratio of 1: 1 at concentrations: dihydroquercetin - 1 mg / ml, glucose - 1 mg / ml, other individual antioxidants and their compositions consisting of several individual antioxidants. According to the obtained voltammetric results, the antioxidant activity coefficients (K, μmol / l min) of individual antioxidants and their compositions were calculated (table 1).

As can be seen from table 1, all the investigated substances and their compositions exhibit some antioxidant activity. However, the highest antioxidant activity was shown by the composition dihydroquercetin + glucose (1: 1) in concentrations of 1 mg / ml.
