In the article it is offered to enter in the technological audit of the lime department of sugar factory the adjusted technique of the definition of the maintenance of calcium carbonate in carbonate breed. For this purpose, a complete chemical analysis of limestone was performed, which includes determination of moisture content, impurities insoluble in hydrochloric acid, the amount of one and a half oxides of aluminum and iron, calcium carbonate (advanced method), and magnesium carbonate, calcium sulfate, alkali metal oxides, potassium, and sodium. The obtained experimental data are summarized in one table and the material balance of all components of carbonate bedrock is summarized. The proposed method made it possible to obtain objective data on the component composition of the carbonate material. This, in turn, avoids many technological problems, namely to reduce the formation of melts in the lime kiln, improve the filtration of juices, increase the ability of lime to chemically interact with water, reduce the volume of water on the juicer etc. Thus, the use of the recommended method for determining calcium carbonate (CaCO3), as part of the technological audit, will allow early adjustment of the process, which will give maximum energy and resource savings, as well as increase the level of environmental friendliness of the enterprise.

The article considers an improved method for determining the content of magnesium carbonate in the carbonate rock. An adjusted method for determining the content of magnesium carbonate was included in the complete establishment of chemical analysis of limestone, which includes the determination of moisture, impurities insoluble in hydrochloric acid, the amount of one and a half oxides of aluminum and iron, calcium carbonate and magnesium carbonate (advanced method), calcium sulfate, alkali metal oxides of potassium and sodium. The obtained experimental data were entered into a single table and summed up the material balance of all components of the carbonate rock. As a result, it was found that this technique includes the following criteria: it is the most accurate, most accessible, and cheap. The use of adjusted methods for determining the content of calcium and magnesium carbonate in limestone will make it possible to establish the objective chemical composition of the carbonate rock and avoid several technological problems. Namely, the excess of uncontrolled magnesium carbonate contributes to the formation of the liquid phase, which in turn reduces the concentration of chemically active lime and promotes the formation of melts in the lime kiln, deteriorating filtration rates, clogging the evaporating station, and so on. Therefore, having information about the real component composition of limestone, the technologist will be able to adjust the technological process in advance, which will lead to the preservation of natural resources while the quality of finished products will not decrease.

Метою даної роботи є встановлення мікроелементного складу екстрактів і настоїв з лікарської сировини – календули лікарської та меліси лікарської. Встановлений мікроелементний профіль включає дані щодо вмісту таких макро- та мікроелементів, як кальцій, калій, натрій, залізо, цинк, мідь в екстрактах і настоях з меліси лікарської та календули лікарської. Серед макроелементів переважає натрій, перевага якого проявляється в календулі лікарській при настоюванні. Велика кількість кальцію також переходить у водно-спиртовий настій з календули лікарської. Переважаючими мікроелементами у водних екстрактах календули лікарської є мідь і цинк. Порівнюючи отримані результати кількості мікро- і макроелементів, які перейшли в екстракти, можна ствердно сказати, що календула лікарська більш багата цими речовинами. Оскільки настої та екстракти рекомендовано додавати як додатковий інгредієнт до овочевих та фруктових соків, відмічено їх позитивний вплив у напрямку забезпечення організму людини у рекомендованій добовій потребі калію та натрію. За результатами проведеного дослідження екстракти та настої меліси лікарської та календули лікарської можна розглядати як незамінне джерело мікроелементів для збагачення фруктово-овочевих соків серед консерв оздоровчого призначення. The purpose of this work is to determine the trace element composition of extracts and infusions from medicinal raw materials - medicinal calendula and medicinal lemon balm.The established micronutrient profile includes data on the content of such macro- and microelements as calcium, potassium, sodium, iron, zinc, and copper in extracts and infusions from Melissa officinalis L officinalis L and Сalendula officinalis. Sodium predominates from certain macronutrients, the superiority of which is manifested in Сalendula officinalis when infused. A large amount of calcium also passes into the aqueous-alcoholic infusion from Сalendula officinalis. Copper and zinc prevail among the determined microelements in water extracts of Сalendula officinalis. Comparing the results obtained, we can say in the affirmative about the micro- and macro elements that have passed into extracts that Сalendula officinalis is richer in these substances. Because infusions and extracts are recommended to be added as an additional ingredient to vegetable and fruit juices, their positive infusion on the human body will increase the recommended daily requirement of potassium and sodium. Based on the results of this study, extracts and infusions of Melissa officinalis L and Сalendula officinalis can be considered as an essential source of micronutrients for enriching fruit and vegetable juices in canned food for health purposes.
