The Impact

The disposal of food waste is a current and pressing issue, urging novel solutions to implement sustainable waste management practices. Fish leftovers and their processing byproducts represent a significant portion of the original fish, and their disposal has a high environmental and economic impact. The utilization of waste as raw materials for the production of different classes of biofuels and high-value chemicals, a concept known as “biorefinery”, is gaining interest in a vision of circular economy and zero waste policies. In this context, an interesting route of valorization is the extraction of omega-3 fatty acids (ω-3 FAs) for nutraceutical application. These fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have received attention over the last decades due to their beneficial effects on human health. Their sustainable production is a key process for matching the increased market demand while reducing the pressure on marine ecosystems and lowering the impact of waste production. The high resale value of the products makes this waste a powerful tool that simultaneously protects the environment and benefits the global economy. This review aims to provide a complete overview of the sustainable exploitation of fish waste to recover ω-3 FAs for food supplement applications, covering composition, storage, and processing of the raw material.

The Impact

This article summarizes the arguments within the scientific discussion on the issue of using mining machines and their life cycle. The main goal of the article is to investigate the impact of a combination of mobile and stationary mining machines and their optimal distribution in the mining process to increase the efficiency of mining and processing of raw materials. The following methods of research were focused on the use of technical indicators for the valuation efficiency of the mining process: a simulation method was used for the distribution of mining machines, comparison analysis was used for the real and past state of mining machines, and a decision tree was used as managerial instrument for optimal alternatives of mining machines. The research empirically confirms and theoretically proves that optimal distribution of mining machines and machine parks is very important for mining companies. The benefit of this research for the mining company was the new location of the machines and the combination of stationary production lines and mobile equipment. The optimal layout of the machines reduced the number of conveyor belts and improved the transfer of limestone processing to mobile devices, saving time, which was reflected in transport costs. The results can be useful for other mining companies seeking to create an optimal machine park.

The Impact

Milk contains several important nutrients that are beneficial for human health. This review considers the nutritional qualities of essential fatty acids (FAs), especially omega-3 (ω-3) and omega-6 (ω-6) polyunsaturated fatty acids (PUFAs) present in milk from ruminant and non-ruminant species. In particular, the impact of milk fatty acids on metabolism is discussed, including its effects on the central nervous system. In addition, we presented data indicating how animal feeding—the main way to modify milk fat composition—may have a potential impact on human health, and how rearing and feeding systems strongly affect milk quality within the same animal species. Finally, we have presented the results of in vivo studies aimed at supporting the beneficial effects of milk FA intake in animal models, and the factors limiting their transferability to humans were discussed.

Abstract Animal fat and proteins, such as milk butter and eggs, are the main ingredients of baked products, and are frequently blamed for food allergies, obesity, cancer and type II diabetes. Therefore, there is an urgent need to replace these ingredients with healthier ones without degrading the organoleptic characteristics of the final product. Microalgae are a great source of protein, minerals and lipids such as omega-3 and omega-6 fatty acids, which are beneficial for human health, offering multiple health benefits such as antioxidant and anti-aging activity. In this study, Chlorella vulgaris microalgae were the selected raw material for the innovative replacers because of their high content in proteins and polyunsaturated fatty acids. The obtained microalgal oil was colour corrected and used to produce brioche-type baked products with 100% animal fat substitution. For protein recovery, the aquatic extract was freeze-dried, producing a dry protein powder that fully substituted the animal protein in the baked products. Finally, the development of bakery products with 100% replacement of both animal fat and protein was achieved. These innovative bakery products showed equal performance to the commercial ones, and even improved organoleptic characteristics according to the sensorial analysis that occurred.

The Impact

Viral infections are a leading cause of morbidity and mortality worldwide, and the importance of public health practices including handwashing and vaccinations in reducing their spread is well established. Furthermore, it is well known that proper nutrition can help support optimal immune function, reducing the impact of infections. Several vitamins and trace elements play an important role in supporting the cells of the immune system, thus increasing the resistance to infections. Other nutrients, such as omega-3 fatty acids, help sustain optimal function of the immune system. The main aim of this manuscript is to discuss of the potential role of micronutrients supplementation in supporting immunity, particularly against respiratory virus infections. Literature analysis showed that in vitro and observational studies, and clinical trials, highlight the important role of vitamins A, C, and D, omega-3 fatty acids, and zinc in modulating the immune response. Supplementation with vitamins, omega 3 fatty acids and zinc appears to be a safe and low-cost way to support optimal function of the immune system, with the potential to reduce the risk and consequences of infection, including viral respiratory infections. Supplementation should be in addition to a healthy diet and fall within recommended upper safety limits set by scientific expert bodies. Therefore, implementing an optimal nutrition, with micronutrients and omega-3 fatty acids supplementation, might be a cost-effective, underestimated strategy to help reduce the burden of infectious diseases worldwide, including coronavirus disease 2019 (COVID-19).

Введение в ежедневный рацион продуктов, обогащенных эссенциальными нутриентами, является актуальной задачей стратегии здорового питания. В этой связи особое место занимают продукты переработки зерна, как основы пирамиды здорового питания. Среди наиболее востребованных незаменимых нутриентов следует выделить полиненасыщенные жирные кислоты, и особенно жирные кислоты семейства ɷ-3. Главным источником линоленовой кислоты из растительного сырья является льняное масло, которое может быть введено в виде тонкоизмельченных семян льна в состав хлебопекарной муки. Химический состав продуктов питания на зерновой основе, полученных с использованием традиционной технологии, характеризуется недостаточной сбалансированностью, невысокой пищевой и биологической ценностью. В связи с этим с целью расширения ассортимента зерновых продуктов функциональной направленности общего, диетического и профилактического назначения на основе полизерновых смесей разработаны методология управления мукомольными свойствами зернового сырья при его переработке для получения продуктов питания на зерновой основе заданного состава и свойств; показана возможность совместного размола пшенично-льняной смеси с получением муки, обогащенной незаменимыми жирными кислотами (НЖК) - омега-3 (линоленовая кислота) и омега-6 (линолевая кислота); сформированы новые виды муки, обогащенные незаменимыми жирными кислотами; определены некоторые физико-химические характеристики пшеничной муки, обогащенной НЖК; выявлены особенности хлебопекарных свойств пшенично-льняной муки. На основании динамики изменения показателя кислотного числа жира (КЧЖ) спрогнозирован срок безопасного хранения пшенично-льняной муки, который составил 9,4 месяца. The introduction of foods fortified with essential nutrients into the daily diet is an urgent task of a healthy eating strategy. In this regard, grain processing products occupy a special place, as the basis of the pyramid of healthy nutrition. Among the most demanded essential nutrients are polyunsaturated fatty acids and especially fatty acids of the ɷ-3 family. The main source of linolenic acid from plant raw materials is linseed oil, which can be added in the form of finely ground flax seeds to baking flour. The chemical composition of grain-based food products obtained using traditional technology is characterized by insufficient balance, low nutritional and biological value. In this regard, in order to expand the range of functional grain products for general, dietary and prophylactic purposes on the basis of polygrain mixtures, the following have been developed: a methodology for controlling the milling properties of grain raw materials during its processing to obtain food products based on a grain basis of a given composition and properties; the possibility of joint grinding of a wheat-flax mixture to obtain flour enriched with essential fatty acids (EFA) - omega-3 (linolenic acid) and omega-6 (linoleic acid) is shown; formed new types of flour, enriched with essential fatty acids; some physicochemical characteristics of wheat flour enriched with EFA have been determined; the features of the baking properties of wheat-flax flour are revealed. Based on the dynamics of changes in the acid number of fat (FAT), the period of safe storage of wheat-flaxseed flour was predicted, which was 9.4 months.

Батыс Қазақстан облысындағы кәсіпорындардың эволюциясы экономикалық дамудың жалпы циклдік сипатына байланысты да, әр түрлі сыртқы және ішкі факторлардың осы салаға әсер етуінен, сондай-ақ даму процесінде сөзсіз ауытқулар салдарынан ауытқуларға ұшырайды. Батыс Қазақстан облысының аймақтық агроөнеркәсіптік кешенін тұрақты дамытудың басымдықтары талдау арқылы анықталуы керек. Зерттеудің мақсаты - Батыс Қазақстан облысының агроөнеркәсіптік кешенінің тиімді және тұрақты дамуын зерттеу болып табылады. Бұл тақырыпты зерттеу кезінде статистикалық-экономикалық әдіс, талдау және синтез қолданылды. Ауылшаруашылық кешенінің жеке аймақ ретінде тұрақты дамуы да, жалпы елдің де дамуы ауылшаруашылық кешенінің тұрақты қалыптасуынсыз мүмкін емес, себебі оның түпкі өнімі қайта өңдеу өнеркәсібі болып табылады, ал оның мақсаты - талаптарына сай халықты сапалы өніммен қамтамасыз ету. Талдау көрсеткендей, ауылшаруашылық өндірісінің қазіргі жағдайы, қолайсыз факторлардың әсерінің күшеюімен сипатталады, ең алдымен табиғи факторлардың өндірісінде, жалпы өсімдік шаруашылығы өнімінің жылдық айырмашылықтарын тудырады, және өз кезегінде мал шаруашылығындағы ауытқуларға әкеледі, сонымен қатар оның әсері өңдеуші салаларда сезіледі, ал бұл өнеркәсіптің шикізаты болып табылады. Зертеу барысында 2015 жылдан бастап Батыс Қазақстан облысының аумағында ауыл шаруашылығы өнімдері өндірісінің күрт төмендегені анықталды, бұл жалпы, сондай-ақ өсімдік шаруашылығы мен мал шаруашылығы салалары бойынша да өндіріс тұрақтылығының төмендеуіне әкелді, және ол бүгінгі күнге дейін жалғасуда. Агроөнеркәсіптік кешеннің шикізат саласындағы өндіріс тұрақтылығының төмендеуі қайта өңдеу өнеркәсібі өнімдерін өндіруде ауытқулардың артуына әкеліп соқтырды, бұның нәтижесінде халыққа азық-түлік өнімдерін ұсынуда тұрақсыздық пайда болды. Батыс Қазақстан облысының АӨК-ін оның салаларының өнімділігі мен кірістілігін арттыруға бағытталған одан әрі дамыту өндірісті жаңғыртуды және қайта жарақтандыруды, оның инфрақұрылымын дамытуды және салалық кластерлерді қалыптастыруды талап етеді.

The evolution of enterprise in the West Kazakhstan region is subject to fluctuations due to both the general cyclical nature of economic development and the impact of various external and internal factors on this industry, as also fluctuations unavoidable in the evolution process. The priorities for sustainable evolution of the regional agro-industrial complex of the West Kazakhstan region should be identified through analysis. The goal of the research is to study the effective and sustainable development of the agro-industrial complex of the West Kazakhstan region. Through studies this topic, the statistical-economic method, analysis and synthesis were used. Sustainable development of the agro-industrial complex of both a particular region and the country as a whole is impossible without the stable functioning of its core - agriculture, the final product of which is used by the processing industry, whose goal is to provide the population with high-quality products in volumes that meet their requirements. Current state of agricultural production, as the analysis shows, is characterized by an increase in the influence of unfavorable factors on production, first of all natural ones, which cause annual differences in the production of gross crop production, which, in turn, convey fluctuations to the livestock industry and, as a result, affects the processing industries. it is the raw material of the industry. In the course of the study, it was found that, since 2015, in the territory of the West Kazakhstan region, there has been a sharp decline in agricultural production, which led to a decrease in the stability of production in general, and in the fields of crop and livestock production, which continues to the present. A decrease in the sustainability of production in the raw materials sector of the agro-industrial complex entailed an increase in fluctuations in the production of products of the processing industry, which ultimately resulted in the emergence of an instability in the supply of food to the population. Further development of the agro-industrial complex of the West Kazakhstan region, aimed at increasing the productivity and profitability of its industries, requires the modernization and re-equipment of production, the development of its infrastructure and the formation of industry clusters.

The Impact

The beneficial effects of fatty acids (FAs) on human health have attracted widespread interest. However, little is known about the impact of FAs on the handling of urate, the end-product of human purine metabolism, in the body. Increased serum urate levels occur in hyperuricemia, a disease that can lead to gout. In humans, urate filtered by the glomerulus of the kidney is majorly re-absorbed from primary urine into the blood via the urate transporter 1 (URAT1)-mediated pathway. URAT1 inhibition, thus, contributes to decreasing serum urate concentration by increasing net renal urate excretion. Here, we investigated the URAT1-inhibitory effects of 25 FAs that are commonly contained in foods or produced in the body. For this purpose, we conducted an in vitro transport assay using cells transiently expressing URAT1. Our results showed that unsaturated FAs, especially long-chain unsaturated FAs, inhibited URAT1 more strongly than saturated FAs. Among the tested unsaturated FAs, eicosapentaenoic acid, α-linolenic acid, and docosahexaenoic acid exhibited substantial URAT1-inhibitory activities, with half maximal inhibitory concentration values of 6.0, 14.2, and 15.2 μM, respectively. Although further studies are required to investigate whether the ω-3 polyunsaturated FAs can be employed as uricosuric agents, our findings further confirm FAs as nutritionally important substances influencing human health.
