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.

(2024) Palamarchuk, Igor; Mushtruk, Mikhailo; Vasyliv, Volodymyr; Shtefan, Yevgenii; Priss, Olesia; Babich, Irina; Karpovych, Inna; Pushanko, Nataliia
One of the most important problems in ensuring the quality of mincemeat preparation in the production of sausages is the effective structuring of components and mixing of their ingredients. To solve this problem, researchers added a multifunctional admixture based on whey protein in the process of centrifugal mixing of the components, which determined the composition of the factor space of the investigated process. Based on the results of the research, the effective content of whey protein, sodium alginate, and soy fiber in the developed recipe was proven, which showed high characteristics in terms of fat-retaining and moisture-retaining ability, digestibility, pH level – activity, and other parameters. The developed formulation made it possible to improve the general indicator of the balance of amino acids in the product and increase the functional-technological and quality parameters of the developed products. The physical and mechanical characteristics of the obtained meat product were evaluated based on the results of physical and mathematical modelling. Modelling was carried out using Federman-on-Buckingham's second similarity theory and the "dimension theory" method, which allows the processing of the obtained experimental data in the form of a criterion equation, which was compiled using Froude, Euler, and Sherwood criteria. The purpose of this study was to obtain dependencies between such process factors as product density, the coefficient of dynamic viscosity of the technological medium, the ultimate shear stress, the change in the concentration of the main impurities of lactic acid in the raw material, the value of the diffusion coefficient and the coefficient of mass transfer in the loading mass, the weight of one load of products, the angular frequency of rotation of the screws of the minced meat mixer, the radius of the rotating working bodies, the characteristic size of the products after grinding. Using the complex criterion equation and the developed program, we find a recommended set of operating mode parameters for preparing minced meat under the conditions of centrifugal influence on the mixing process and the action of the specified factors.

(2024) Popova, Inna; Palamarchuk, Igor; Zheplinska, Mariia; Mushtruk, Mikhailo; Vasyliv, Volodymyr
The content of heavy metals both in plants and in soils for growing agricultural crops steadily changes the state of ecological safety of the corresponding biocenosis. An increased amount of trace elements and compounds of heavy metals causes metabolic disorders in plant tissues. As a result, there is an accumulation of toxic elements in the crops, which disrupts the iocenosis in the system for both farm animals and humans. Therefore, the contamination of plant raw materials, in particular chicory, for the food industry with ions of heavy and toxic metals is a significant environmental problem

(2021) Parkhomenko, Anastasia; Mukoid, Roman; Vasyliv, Volodymyr
The prospects of using buckwheat and buckwheat malt for the production of low-gluten beer are shown. The choice and quantity of unmalted raw materials - crushed white buckwheat and buckwheat malt for the production of low-gluten beer (95% barley malt and 5% buckwheat malt or crushed white buckwheat) are substantiated. Beer brewed with a partial replacement of barley malt for buckwheat malt has better physicochemical properties than beer brewed with a partial replacement of barley malt for crushed white buckwheat. For the production of low-gluten beer, it is recommended to use 5% buckwheat malt as a low-gluten raw material.

The manuscript describes a new method of red beet processing and the technology of manufacturing food colorant from the juice concentrate, which is natural, safe and useful analogue to existing expensive offers on the market of similar goods that have chemical origin not useful for regular consumption. Nowadays in order to give to food products a colour, close to natural coloring of fruits and vegetables, expensive synthetic dyes are used, which might have cancer-inducing effect when being accumulated by human organism. Therefore improving the technology for producing food grade dye from red beet juice is remarkably important task. Currently, there is a problem for vegetable processors – pectin substances complicate the process, like the illumination of juice and negatively affect its storage capacity. The article below reveals and substantiates the necessity of using a natural carbon-containing adsorbent shungite for the purification of beet juice from pectin substances. On the basis of the study, the authors suggest a more cost-effective way of producing a food dye from juice concentrate, which allows avoiding usage of expensive enzyme processing additives.

In the juices of sugar beet, the viscosity of the produced viscosity is determined. They contain sugars and non-sugary compounds. If they are in the form of associated or complex compounds, then when their state changes. Well under the action of external factors or at their removal from a solution it is obligatory. Its rheological properties will also change. Therefore, with the help of determining the viscosity, it is possible to conclude the complex processes that take place in juices under the action of the effects of vapor condensation cavitation, namely: the force between Leculiary bonds, the size of molecules, and the length of chemical bonds, etc. The paper presents studies of the influence of vapor-condensation cavitation effects on the change of such rheological properties of cell and diffusion juice as viscosity and surface tension. The viscosity of the steam treated juice is affected by complex transformational changes that occur with the associated compounds under the effects of vapor-condensation cavitation, which leads to their destruction and this leads to a decrease in their molecular weight and changes in concentration. Studies have shown that with increasing steam consumption for juice processing in the range of 0 – 1.5% by weight of juice the upper tension increases. Such legitimacy is also an indirect confirmation of the processes of destruction of the association. important compounds of diffusion juice under the influence of the effects of steam condensation cavitation.

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.

(2024) Loiko, Serhii; Romanova, Zoriana; Zheplinska, Mariia; Romanov, Mykola; Vasyliv, Volodymyr
Using unmalted grain is one of the ways to improve quality, reduce production costs, and create new types of beer. However, the enzymatic activity of such raw materials is zero, so the use of enzyme preparations is relevant. The purpose of the study was to compare the quality indicators of 100% malt beer and beer with the replacement of malt with unmalted barley using enzymes. The methods of technical and chemical analysis were used to determine the organoleptic and physicochemical indicators of beer. Recommendations have been developed for the intensification of wort preparation using different types of grain raw materials - unmalted barley and rice groats with the addition of enzyme preparations from Novozymes (Denmark) at various stages of brewing. When testing new enzyme preparations (β-glucanase complex, xylanase), filtration time, wort viscosity and β-glucan content. and arabinoxylans decreased by approximately 20% compared to control samples. The use of a new enzyme preparation contributed to a better breakdown of substances, which affected the quality and duration of filtration. This leads to an improvement in the quality of the wort, a reduction in the duration of the process, and a reduction in the cost of raw materials. To ensure the necessary ratio of substances in the wort, it is necessary to introduce complex enzyme preparations - peptide hydrolase, α-amylase, endo-β-glucanase (Ceremis Plus). Preparations containing endo-β-glucanase (Ultraflo Max) should be used at the beginning of mashing to improve the rheological properties of the wort and reduce its viscosity, which improves the filtration process. To obtain beer with the required degree of fermentation during mashing, it is better to use new enzyme preparations (glucoamylase). The practical significance of the research is that the use of large amounts of unmalted grain together with exoenzymes such as Ultraflo Max and Ceremis Plus will allow brewers to produce worts and beers of the same composition and quality as premium worts and beers using only malt.
