Determining patterns in the separation of hemp seed hulls

The subject of this study is the technological processes of separation, the hull of industrial hemp seeds, an aspiration column, and whole kernels. The problem solved was determining the technical and technological solutions that could enable the intensification of production processes for separating industrial hemp seeds. The separation of hemp seed hull by linear dimensions on sieves with round and elongated holes has been investigated. It was found that the percentage of seed hulls retained by sieves with circular holes was 25.98 % for ø3.5 mm, 23.59 % for ø3.0 mm, and 40.28 % for ø2.0 mm, respectively. Sieves ø3.5 mm and ø2.0 mm made it possible to obtain seed hulls fractions with two components conditionally different in the «mass-size» ratio. Using sieves with elongated holes enabled obtaining fractions consisting of at least three components. Sieves with elongated working holes of 3.0×20 mm, due to their low ability (1.76 %) to retain hemp seed hull components, were ineffective. The clogging levels of kernels in seed hulls, separated by linear dimensions on combined sieves with round and elongated holes, were as follows: separation option No. 1 – 48.70 %, option No. 2 – 45.74 %, option No. 3 – 60.25 %, option No. 4 – 49.32 %, respectively. It was established that the use of an aspiration column made it possible to remove up to 32.1 % of clogging in the form of a light fraction. The application of the aspiration column reduced the content of seed coating in separation option No. 1 by 3.0–5.7 times, option No. 2 by 1.35–3.7 times, option No. 3 by 1.9–11.2 times, and option No. 4 by 1.5–4.8 times, respectively. The quantitative and component composition of seed hulls fractions obtained under conditions of using an aspiration column with set rational values of the air damper opening angle α=53° and the vertical tilt angle of the air channel β=6°, was as follows: Stage I – «heavy» fraction – 51.78 %, 27.56 % – waste, up to 20 % – «light» fraction of Stages II and III

Porcine circovirus 3: a new challenge to explore.

The intensification of production processes, resulting from the rise in pork production, contributes to environmental changes and increased interaction between humans, animals, and wildlife. This favorable scenario promotes the spread of potent viral species, such as PCV3, increasing the potential for the emergence of new pathogenic agents and variants. These changes in the epidemiology and manifestation of PCV3 highlight the need for enhanced understanding and control. The current literature presents challenges in the classification of PCV3, with different groups proposing diverse criteria. Establishing common terminology is crucial to facilitate comparisons between studies. While consensus among experts is valuable, new approaches must be transparent and comparable to existing literature, ensuring reproducible results and proper interpretation, and positively impacting public health. This study aims to review the literature on PCV3 infection, exploring its key aspects and highlighting unanswered questions.

Process intensification for production of dispersants via integration of reaction and separation in a horizontal thin film evaporator

Process intensification can be achieved in specialty chemicals manufacturing via transition from batch-to-continuous processing. However, the absence of headspace in a continuous tubular reactor limits the ability to remove volatile byproducts from the reacting liquid flow. Previous studies showed that the production of succinimide dispersants follows a two-step amidation-dehydration pathway in which water is formed as a by-product. The inability to remove this water imposed a thermodynamic equilibrium limitation on the dehydration step, and hence necessitated a downstream drying step to obtain a dehydrated dispersant product within commercial specifications. In the present study, the use of an agitated, horizontal thin film evaporator (TFE) was investigated as a continuously operated reactive separator which combines reaction and dehydration into a single operating unit, reducing the overall cost and physical footprint of the process. The continuous TFE unit was first experimentally investigated as a stand-alone, integrated reactor-separator. Using this configuration, the obtained imide yield consistently exceeded the maximum thermodynamic yield at each operating temperature, confirming the efficiency of the integrated reaction and separation steps in the TFE. Next, the unit was modeled by integrating reaction kinetics with mass and energy balance equations, using appropriate correlations for heat and mass transfer from the literature which were verified for the experimental set-up. This model provided insights into the system behavior across different operating conditions, including the role of forward and reverse reactions along the TFE unit length. The model was then used to confirm the feasibility of replacing the two-step tubular reactor-evaporator process with a single TFE unit as an intensified reactive separator, further reducing the physical footprint of the process by enabling compact modular process designs.

Challenges of Economic of Georgia: Good and Bad EconomicGrowth

The Georgian economy has been undergoing serious transformations over theyears. The reforms carried out by the government affected all spheres of theeconomy - health care, education, industry, the military-technical complex,etc. The annual growth of the economy is approximately 4.8%. The EU,partner developed countries and donor international organizations allocatehuge financial resources for the implementation of the changes planned bythe government. Despite this, the economy of Georgia is in a difficult situation.The reason of economic stagnation in which the country has been for years isan extensive vector of development of the national economy. Investmentprojects carried out in the country in recent years are extensive in most cases.These projects are aimed at increasing current profits. They mostly are notoriented to long-term perspective. Intensification projects based on scientificand technical progress that are capable to change the level of productionqualitatively are few. Despite the lack of an innovative scientific and technicalbackground the economic indicators are increasing. However, the analysis ofthe indicators’ growth factors shows the lack of development of the nationaleconomic system. The data does not reflect the real economic statement andpoint to an extensive (so-called bad growth) growth of the national economyand will lead to economic and political crisis. The intensive and extensivefactors of economic growth is discussed and analyzed in the paper. Therecommendations and measures are developed by the authors for improvingthe economy through the intensification of production processes.

ОСНОВНЫЕ ТРЕНДЫ РОСТА РЕГИОНАЛЬНОГО СЕЛЬСКОГО ХОЗЯЙСТВА: ОТ ОБЪЕМОВ К УСТОЙЧИВОСТИ

The strategic task until 2030 for the agro-economic systems of the country and its regions is to increase the average annual growth rate of volumetric indicators of agricultural production to 3%, which is twice as high as the achieved value. To achieve this aim, it is necessary to develop and implement effective mechanisms to smooth out the abrupt growth of production volumes and ensure the sustainable development of agricultural sectors. The development of the agricultural sector of the Republic of Tatarstan shows positive trends in the growth of volumetric indicators of production over the past five years. The volume of gross agricultural output in the region increased with an annual growth rate of 21.62 billion rubles. At the same time, the volume of production growth in the crop and livestock sectors amounted to 11.11 and 10.49 billion rubles, respectively, which demonstrates the uniform development of the two main industries. The growth in volumetric indicators of product production is mainly due to the intensification of production processes, the introduction and development of innovative technologies. Along with this, abnormal weather conditions have a negative impact on the process of sustainable development of agriculture, as evidenced by the results of 2021, when the total production volume was only 80.1% of the previous year’s level, and crop production decreased by 38.7%. The identified trend once again emphasizes the need to search for adaptive methods of farming in accordance with climate change by moving at a more intensive pace to the creation of drought-resistant varieties, the development of moisture-saving technologies and the active implementation of reclamation measures. Livestock farming is developing at a more sustainable pace, although there is a decline in the numbers of certain animal species. However, this process does not affect production volumes due to increased animal productivity. The industry is in the process of gradually replacing low-productive animals with highly productive breeding stock. To transition to sustainable development of agriculture in the republic, it is necessary to continue work on adapting technological processes to climate change, creating and introducing new varieties, developing genetic technologies for animal breeding, using digitalization and robotization of the industry.

Economic Challenges in Georgia: Assessing Good and Bad Growth

The Georgian economy has undergone significant transformations over the years due to government-led reforms that have impacted various sectors, including health care, education, industry, and the military-technical complex. Despite substantial financial support from the European Union, partner countries, and international donor organizations, Georgia’s economy faces challenges. The prolonged economic stagnation can be attributed to an extensive development approach, characterized by investment projects primarily focused on short-term gains rather than long-term sustainability. While economic indicators show growth, a closer examination reveals deficiencies in the national economic system. The data reflects an extensive (often referred to as “bad growth”) expansion of the national economy, driven by investment projects aimed at immediate profits. However, these projects lack a forward-looking perspective and fail to harness scientific and technical progress for qualitative production improvements. The absence of innovative scientific and technical foundations underscores the need for a shift toward intensive growth strategies. In this paper, we delve into both intensive and extensive factors of economic growth. We explore how investment projects can be reoriented to prioritize long-term benefits and sustainable development. Our recommendations emphasize the intensification of production processes, fostering innovation, and creating a robust economic ecosystem that transcends short-term gains. By addressing these challenges, Georgia can navigate toward a more balanced and resilient economic future.

FISH FARMING IS A PROMISING BRANCH OF ENSURING FOOD SECURITY OF THE EARTH'S POPULATION

Based on marketing research, it has been proven that aquaculture is one of the fastest growing branches of food production in the world. The main method of increasing fish productivity in ponds is fish feeding, which is an objective reality with high intensification of fish farming. With the intensification of production processes, the role of feeding is constantly increasing, and the cost of feeding in the cost price of fish is about 40% and has an upward trend. In this connection, the problem of rational feed use becomes extremely important. It is justified that the use of high-quality feed and feed additives in the diet of fattening animals significantly increases the productivity and profitability of the operation of livestock, poultry, and fish farms. 160 factories are engaged in the compound feeds production in Ukraine, the production capacity of which is 7.5 million tons per year. The specified indicator should be realistically increased to 15 million tons of finished products per year. It is established that we will need to produce 60 percent more food by 2050 to feed the world's 9.3 billion people according to estimates compiled by the Food and Agriculture Organization (FAO). Therefore, animal protein production is expected to increase with this increase. According to IFIF estimates, the world production of compound feeds has reached more than 1 billion tons per year. Top 10 countries in world compound feed production in 2021–2022 are presented (according to Alltech Agri-Food Outlook 2023). The structure of compound feeds production by types of agricultural animals and poultry in the world in 2022 is summarized. It is proved that the production of fish compound feeds continues to grow in all the world regions. In the world (as well as in Ukraine), fishing and aquaculture play and will play a significant role in the coming centuries in ensuring the food security of the global population. It is necessary to make changes in policy, management, stimulate innovation and investment to the industry to ensure the food security of the planet through fisheries and aquaculture. It is established that the world volume of aquatic bioresources production is constantly growing and in 2022 reached the value of 176 million t/year. More than 150 million tons of aquatic biological resources were used for human consumption. In the conditions of the formation of market relations, against the background of significant costs for feed, feeding fish should be based on careful calculations, the logical conclusion of which should be economic expediency. On the basis of the marketing research of the situation on the market of feed supplements, a shortage of protein vitamin supplements and complete feeds for domestically produced fish was revealed. The restraining factors for the use of foreign supplements are their cost and interruptions in supply.

Ways of balanced use of vermiculture biotechnology in the conditions of anthropogenic load on the environment

The high energy potential of organic waste allows its use in bioconversion technologies, where waste from one production cycle is a raw material for further production to produce environmentally friendly fertilizers, energy carriers and feed additives. The article presents the results of experimental studies on the environmental efficiency of vermiculture on organic waste from livestock, crop production, gardening and forestry under anthropogenic load. It is proved that due to the biological characteristics of vermiculture, which allows to consume a large amount of organic residues, enrich them with its own microflora, enzymes, biologically active substances and release them as processed products (coprolites), this technology to some extent solves the problems of balanced nature management. It has been determined that in the conditions of intensification of production processes, secondary organic raw materials contain a number of pollutants - heavy metals and toxic metals that can accumulate in coprolites (vermicompost). An approach is proposed that solves the problem of pollutant migration and involves the introduction of 3% zeolite from the Sokyrnytsia deposit in the Transcarpathian region into the vermiculture substrate. Experimental and analytical determination of the environmental efficiency of the proposed approach has shown that its practical application in solving the problems of balanced nature management allows to reduce the accumulation of Plumbum by 13.6 % and Cadmium by 22.6 % in vermicompost, which improves the quality of this organic fertilizer and creates prerequisites for obtaining environmentally friendly products. Key words: ecology, biotechnology, organic waste, red California worm hybrid, bioconversion, natural minerals, minimization of environmental pollution, sustainable environmental management.

Haber-Bosch process intensification: A first step towards small-scale distributed ammonia production

High operating pressures are needed in the Haber-Bosch process to push up the NH3 conversion, which is limited by the thermodynamic equilibrium. This evidence hinders the application of distributed renewable ammonia production on small-scale. One possible solution to overcome this problem is the NH3 removal downstream the reaction stage. Ammonia separation from unconverted gases can be performed either with solid-state species (i.e., metal halides or borohydrides), that react reversibly with gas phase NH3, or liquid solvents. Among liquid solvents, traditional NH3 absorption technologies (water, aqueous acids or NH4H2PO4) or novel absorption technologies (ionic liquids or deep eutectic solvents) can be applied. In this respect, the aim of this work is to analyse the NH3 production process intensification, introducing the NH3 removal section through absorption with a phosphate solution downstream the reaction stage. The use of absorption for ammonia separation may open the door to moderate pressure synthesis loop and may pave the way for a down-scalable process based on renewable energy sources.

ERROR ESTIMATION OF THE DEVELOPED METHOD FOR UNGROUNDED AC SYSTEMS TO DETERMINE THE NETWORK INSULATION

The problem of efficient and safe mining has recently become more relevant due to the intensification of production processes, for example, during the operation of electrical installations at mining enterprises, the insulation of electrical networks and electrical equipment undergoes a change in the electrical insulating properties of materials, which reduces the electrical safety. The network insulation admittance determines the safety of electrical receivers and operational personnel in mining facilities, since the current of a single-phase earth fault is directly proportional to the value of the network insulation admittance, and by controlling its active and reactive components, this will allow for a violation of the integrity of the insulation, thereby taking preventive measures. The article depicts the analysis of the reliability of the devised method by estimating the error of insulation parameters in ungrounded AC systems which is done by indirect measurements. Graph-analytical studies of relative root-mean-square error reveal that the accuracy of the calculation in the devised method can be effectually managed by selecting the susceptance of the additional capacitor and accuracy class of measuring units.

RESEARCH THE COMPLEX INFLUENCE OF THE COMPONENTS THE CHOCOLATE MASS ON ITS PROPERTIES AND COMPETITIVENESS FOR VARIOUS INDUSTRIES

Chocolate glaze is a large-tonnage component of various branches of food technology, which also performs important technological tasks, namely: helps to slow down oxidation processes; improving emulsifying and dispersing properties; prevents hardening of certain types of products; prevents the ingress of moisture, which increases the shelf life of the confectionery, etc. At the first stage, the main problems of production of the confectionery industry are determined - they require a scientific justification for the choice of competitive components of production technology, taking into account quality-cost indicators. Next, for the specified parameters of the production technology determine the components of the formulation of chocolate glazes. Analysis of the system of results and calculation equations allowed to offer recommendations for the intensification of production processes: effectively reduces the viscosity of compositions based on cocoa butter, which, in turn, makes it possible to use them for partial replacement of lecithin in the manufacture of confectionery. Thus, based on the conducted research, it is possible to conclude that the fat for a glaze must be chosen taking into account its physical properties and possibility to regulate rheological properties of the glaze. The speed of fats crystallization must allow the glaze to quickly crystallize after facing and not to chip.

Improving the performances of supported NiCo catalyst for reforming of methane powered by magnetic induction

NiCo supported magnetic nanoparticles can catalyze the steam reforming of methane and at the same time provide the heat necessary to run the process by dissipating an external radio frequency electromagnetic field. Magnetic samples with different Ni:Co molar ratio and total metal loading on the support have been synthesized using a traditional impregnation procedure and characterized in terms of morphological and structural properties. The ability of the materials to provide process heat was assessed by temperature measurements. Methane conversion value and syngas composition have been measured for different applied field amplitude. The sample with a composition Ni50Co50_30 wt% was found to be the most performing in terms of conversion obtained with the same applied magnetic field. The developed magnetic catalysts contribute to the transition to distributed hydrogen production and help to tackle some of the challenges related to the intensification of production processes by electrification.

The task consisted in creation of a mathematical model of a production and transport system for optimization of operation of sinter production with raw materials traffic. The mathematical model is based on a dynamic transportation problem with delays.

Разработка методов выбора средств защиты от пыли органов дыхания для горнорабочих

Currently, the mining industry of the Republic of Uzbekistan is dominated by an open method for solid minerals extraction. In the open pit mining, dust is the main adverse production factor. Its concentration in the environment depends on the development technology, the type and humidity of the mineral and host rocks, the mining equipment used, anti-dust measures, etc. Increase in the volume of mineral extraction due to the intensification of production processes and the introduction of high-performance equipment leads to an increase in the level of dust generation at the workplaces. In this regard, the fight against dust as a harmful professional factor remains an urgent task. In a dusty atmosphere, especially with a high concentration of hazardous suspended particles, various means of individual respiratory protection are used. This allows a significant reduction in the inhaled fraction. Conducted research proved that the real coefficients of respiratory protection in the modern personal protective equipment in the production conditions do not correspond to the declared ones. The main reason is the penetration of the unfiltered air into the area under mask through the gaps between the protective mask and the face of the worker. The necessity of developing a methodology for the selection of respirators that will provide reliable protection of the respiratory organs of the workers was identified. The dust load attributable to the respiratory organs of a miner is determined considering the use of BPS and ASDA respirators.

Sustainability Assessment of Family Agricultural Properties: The Importance of Homeopathy

Family farming is a lifestyle and agricultural base that has ensured food for the world’s growing population in addition to the family’s own subsistence. However, the intensification of production processes to primarily generate exportable surpluses is based on the constant input of industrial inputs of low local socioeconomic viability. This study aims to evaluate the sustainability of family farms and their impact on the adoption of homeopathy instead of traditional/conventional intensification techniques. The study was conducted at six family farms located in the Serrana Mesoregion, Santa Catarina, Brazil, and include farms were classified according to the management and representativeness of their agricultural activity, i.e., conventional grains-cattle, milk-grains, grains and diversified, and according to their ecological basis, i.e., agroecological and organic. To discuss the sustainability of the family farms that were evaluated, the of metrics emergy synthesis, ecotoxicity potential and socioeconomic indicators are used. The results indicate that conventional diversified property has the best overall performance with regard to sustainability, including emergy yield ratio (EYR 1.88), emergy investment ratio (EIR 1.13), return on assets (1.22), hourly income of work (36.6 BRL/h) and income sufficiency (3.3). Agroecological and organic properties have better performance in renewability (76% and 75%), environmental load (ELR = 0.32 and 0.34), sustainability (ESI = 4.78 and 3.5) and potential ecotoxicity (1.736 and 1.579 kg 1.4 DCB-eq/ha). The contribution of homeopathy in an alternative scenario results in a 19% reduction in nonrenewable flows in conventional management properties and a decrease of up to 91% in ecotoxicity in grain + cattle properties. Using homeopathy, the return on assets and profit margin can be increased by up to 43% and income per hour of work and income sufficiency can be increased by 20% and 16%, respectively. This study contributes to discussions about the importance of using homeopathic therapies as a viable strategy that can be used in strategic public policy plans to improve the sustainability of family farms.

Application of additive technologies in mechanical engineering for production of form-forming riggings

The article discusses the process of using additive technologies in the manufacture of formbuilding equipment. It is supposed to reduce the manufacturing time and labor costs of workers by using non-traditional technological systems in the manufacture of the form-building equipment’s model, which has qualitatively new properties and capabilities and also significantly increases the level of automation and intensification of production processes. When designing a technological process high information and computerization, a certain level of electrification and energy supply are required, therefore, the design of new technologies is based on rational technological processes, using accumulated experience, and a new system approach developed on the basis of the unity of production design technology using CAD/CAE/CAM systems. The extrusion method of three-dimensional printing using the FDM technology with the use of a new modified material of the PA12CF brand was adopted as the basis for the production of form-building equipment. This material is a polyamide-12 composite plastic reinforced with carbon fibers. The use of additive technologies using modern computer modeling based on the unity of technological systems is an urgent task. These technological systems will significantly increase productivity, reduce the production area occupied by equipment, reduce the duration of the production cycle, reduce the number of workers employed in production, and make it possible to switch to technologies that do not require paper-based design documentation. At the same time, additive technologies are open to their further development and have great potential to evolve and be modified in accordance with the changing external conditions on the labor market.

Double-stage membrane-assisted anaerobic digestion process intensification for production and recovery of volatile fatty acids from food waste

The potential of organic waste streams (i.e., food waste) for the sustainable production of precursor chemicals such as volatile fatty acids (VFAs) using anaerobic digestion (AD) has received significant attention in the present days. AD-derived VFAs have great market appeal if the challenges with their recovery and purification from the complex AD effluent is overcome. In this study, a microfiltration immersed membrane bioreactor (MBR) was used for the production of VFAs from food waste and simultaneously in-situ recovery of VFAs. The MBR set-up was applied for 98 days, with a maximum yield of 0.2 gVFA/gVSadded at an organic loading rate (OLR) of 4 g VS/L/d. The recovered permeate was then subjected to further purification using a side stream ultrafiltration unit. It was found that the removal rates of total solids (TS), total suspended solids (TSS), dissolved solids (DS), volatile solids (VS) and volatile suspended solids (VSS) were above 70–80% in both membranes (10 kDa and 50 kDa), and Phosphorus (P), Total Kjeldahl Nitrogen (TKN), chemical oxygen demand (COD), and NH4+-N were also removed partially. Particularly, VFAs concentration (above 6 g/L) was higher for 10 kDa at pH 5.4 in ultrafiltered solution and permeate flux decline was higher for 10 kDa at pH 5.4. These results are also supported by the measurement of UV–Vis spectra of the solution and visual appearance, providing a promising approach towards building a VFAs-based platform.

Physical Processes in the Thermal Vacuum System

Physical processes occurring during dehydration of heterogeneous materials in a thermal vacuum system have been analyzed. It has been demonstrated that the thermal-vacuum method provides dehydration and simultaneous wet-stock dispersion due to thermal diffusion, shock-wave and ionization effects, thereby leading to formation of novel-type nanodispersed material at minimum energy input. In recent years the intensification of production processes, as well as the solution of energy- and resource-saving problems have taken on great significance. For the sake of dehydration working-cycle improvement, combination of several process procedures in a single installation is used, resulting in both the intensification of the production process and the reduction in capital expenditures. There are the facilities, where the simultaneous use of mechanical grinding operation and the drying process is practiced. In this case, a preheated air is used as a drying agent, and this considerably increases the energy demands of the technological process. This phenomenon is attributed to the impact action and friction of material particles against grinding surfaces of the mill, to the appearance of new surfaces at crushing, and also, to the dust-gas mixture turbulence in the mill working area. That requires substantial power consumption and prevents from obtaining the product with desirable indicators, in particular, the with dispersion and moisture content, which substantially affect the quality of materials produced from fine-grained products. The analysis of fine grinding methods has shown that the most rational method of material grinding is the combination of impact loads. The impact loads facilitate the structure destruction of wet stock, while the abrasion loads acting in the field of high turbulent flows lead to the material destruction. The aim of the present work has been to define the physical processes in the thermal vacuum system, which can efficiently provide dehydration along with simultaneous dispersion of wet material, yielding a dried and ground feedstock in a short span of time.

RESEARCH OF THE INFLUENCE OF THE COMPONENTS OF CHOCOLATE GLAZES ON THEIR RHEOLOGICAL CHARACTERISTICS

Chocolate glaze is a large-tonnage component of various branches of food technology, which also performs important technological tasks, namely: helps to slow down oxidation processes; improving emulsifying and dispersing properties; prevents hardening of certain types of products; prevents the ingress of moisture, which increases the shelf life of the confectionery, etc. At the first stage, the main problems of production of the confectionery industry are determined - they require a scientific justification for the choice of competitive components of production technology, taking into account quality-cost indicators. Next, for the specified parameters of the production technology determine the components of the formulation of chocolate glazes. As an example, the results of studies of selected technological parameters of some compositions of chocolate glazes, a comparative analysis of their effectiveness on the rheological properties of compositions based on cocoa butter: alternative surfactants – standard lecithin – alternative surfactants - monoglycerides and a mixture of mono-, di- and triglycerides from palm oil by glycerolysis in the presence of an alkaline catalyst. Analysis of the system of results and calculation equations allowed to offer recommendations for the intensification of production processes: effectively reduces the viscosity of compositions based on cocoa butter, which, in turn, makes it possible to use them for partial replacement of lecithin in the manufacture of confectionery.

Research of ostrich fat properties when melting in electrochemically activated medium

In recent decades, there has been a growing scientific interest in various kinds of technologies using electro-activated solutions with high reactivity and representing a powerful toolkit for intensification of production processes. However, theoretical knowledge about the regularities of change in fat properties during melting in an electrolyte is rather fragmentary, scarce and often contradictory. The work is devoted to the study of the main factors influencing the change in physical and chemical properties and yield of fat in the process of melting using catholyte, to substantiate the feasibility of its use and develop an industrial line for obtaining fat. The object of studies was ostrich fat obtained by traditional method – by melting in water and by experimental technology – in catholyte as well as technological regimes of fat extraction. According to the data obtained, the fat melted at pH of catholyte 11, temperature 100 and 75 °С was characterized by low values of acid number – 0,45 mg KOH/g and 0,40 mg KOH/g, respectively. The opposite trend was observed with a successive decrease in the alkalinity of the ECA medium and an increase in the melting temperature of the fat, which led to an increase in the content of secondary oxidation products in the experimental samples. It was found that due to the high reactivity of the EСA medium, the temperature and pH of the catholyte increased, the intermolecular interaction within the fat phase decreased, which increased the mobility of lipid molecules relative to each other. The lowest values of fat viscosity (0,42 and 0,4 kPa?s) were recorded when treating fatty raw materials in catholyte with pH 10.5 and 11 and temperature 100 °С. It is shown that increasing the pH of the catholyte contributes to minimizing the values of peroxide number of ostrich fat, in contrast to the heating temperature. It is established that processing of raw materials in catholyte at 75 °C resulted in the yield of fat 88,4–90,1%, which is almost 1,4 times higher than when melted in water. In the wet method of mellowing in water, denaturation of protein structures and a higher degree of fat extraction can be achieved at a mellowing temperature above 75 °C, in contrast to the proposed method of processing raw materials.
