Production of high-quality and safe food products in the conditions of technogenic environmental pollution is a problem worldwide, especially in Ukraine. As a result of the disaster at the Chornobyl Atomic Power Plant, radioactive substances, including caesium-137, contaminated the soil not only in Ukraine, but in many other countries. Zhytomyr Oblast is the fifth largest oblast in Ukraine and one of the regions that were the most damaged by the accident. Furthermore, this territory is contaminated by the most toxic heavy metals – lead (Pb) and cadmium (Cd) that actively migrate in the biological system: soil→ plant → animal → production → human, intensely accumulating in the products of plant and animal origin. The complex ecological situation and broad spectrum of biological and toxic actions of 137Cs, Pb, Cd require a number of measures that would prevent transformation of radioactive elements and heavy metals in the organism of animals, increase animals` productivity and safety of the food products made in the conditions of the Ukrainian Polisia. Therefore, we aimed at substantiating the practicability of using silage-concentrate, silage-concentrate-root vegetable and silage-concentrate-hay types of diet for young cattle during fattening and determining the impact of accumulation of 137Сs, Pb and Cd in livestock products. To perform the studies, we formed three groups of young bulls of Ukrainian Black Pied cattle using the method of analogues with creating comfortable maintenance condition and organization of in-detail planned feeding. The diet was composed of fodders prepared in the conditions of radioactive contamination. The laboratory surveys indicated that the main sources of 137Cs ingress in the organism of the animals were roughages and various types of silages, and the sources of heavy metals Pb and Cd were hay of red clover and concentrated fodders. In the experimental studies, we determined absolute and average daily weight gains, expenditures of metabolic energy per 1 kg of weight increment, specific activity of 137Сs and concentrations of the heavy metals (Pb and Cd) in the biological system “fodder-animal-production” during feeding of bulls with various-type diets in the conditions of the III zone of radioactive pollution. It was confirmed that substituting maize silage and carbohydrate fodders increased the average daily gains in the live weight by 2.3–4.6%, decreased specific activity of 137Cs by 8.7–20.1%, the content of Pb by 36.2%, Cd by 34.1–66.7% in the longissimus at silage-concentrate-root vegetable and silage-concentrate-hay types of diet for bulls. Thus, use of silage-concentrate-root vegetable and silage-concentrate-hay types of diets compared with silage-concentrate feeding had a positive effect on their productivity and safety of the food production.

<p>The results of studies of the content of residues of veterinary drugs in food indicate that when growing all types of productive animals, a significant number of antibiotics, sulfonamide and nitrofuran preparations of various spectrum and mechanism of action accumulate in meat, milk, eggs, as well as for preventive and therapeutic purposes and honey.</p><p>We registered that food products of animal origin contain residues of veterinary preparations that do not exceed the MPC. Despite the ban on the use of antibiotics as stimulators of animal productivity, they are more often found in pork and beef, which indicates the use of these antimicrobials in the production of productive animals. Chloramphenicol was most often found in beef and pork, in rabbit meat, goose meat, chicken meat and honey, this antibiotic was present only in sporadic cases, and in milk its presence was not proven during monitoring studies. Nitrofuran preparations were detected mainly in beef, chicken, goose and honey, and in the last reporting year (2016), their presence was not found in these products, except for honey. Studies have shown that food eggs did not contain residues of nitrofuran drugs during the study period. The use of antibacterial drugs and anthelmintics in livestock breeding is confirmed by the fact that about 40% of the samples contain residual amounts of sulfanilamide preparations in the range of 50-70% of the MPC and about 20% of the samples contain residual amounts of anthelmintics. In Ukraine, control of the remnants of veterinary drugs in food products formally is not carried out. Of the group of fluoroquinolones, only enrofloxacin and norfloxacin are monitored, of the B-lactam group, amoxicillin, ampicillin, benzylpencilin from the aminoglycoside group-gentamicin, lincomycin, streptomycin, and dihydrostreptomycin. As for sulfonamide drugs, control is conducted only for 9 seconds with a very large group of these drugs. Particular attention when controlling the content of residues of veterinary drugs in livestock products should be given to methods for identifying these substances and improving existing research methods. We also suggested to extend the indicators mentioned in the "State Monitoring Plan for Residual Amounts of Veterinary Preparations, Pollutants and Toxicants in Products of Animal Origin" for greater control over the animal production and use of antibacterial substances in the farms.</p>

The nutritional quality of animal products is strongly related to their fatty acid content and composition. Nowadays, attention is paid to the possibility of producing healthier foods of animal origin by intervening in animal feed. In this field, the use of condensed tannins as dietary supplements in animal nutrition is becoming popular due to their wide range of biological effects related, among others, to their ability to modulate the rumen biohydrogenation and biofortify, through the improvement of the fatty acids profile, the derivate food products. Unfortunately, tannins are characterized by strong astringency and low bioavailability. These disadvantages could be overcome through the microencapsulation in protective matrices. With this in mind, the optimal conditions for microencapsulation of a polyphenolic extract rich in condensed tannins by spray drying using a blend of maltodextrin (MD) and gum Arabic (GA) as shell material were investigated. For this purpose, after the extract characterization, through spectrophotometer assays and ultra-high-performance liquid chromatography-quadrupole time-of-flight (UHPLC-QTOF) mass spectrometry, a central composite design (CCD) was employed to investigate the combined effects of core:shell and MD:GA ratio on the microencapsulation process. The results obtained were used to develop second-order polynomial regression models on different responses, namely encapsulation yield, encapsulation efficiency, loading capacity, and tannin content. The formulation characterized by a core:shell ratio of 1.5:5 and MD:GA ratio of 4:6 was selected as the optimized one with a loading capacity of 17.67%, encapsulation efficiency of 76.58%, encapsulation yield of 35.69%, and tannin concentration of 14.46 g/100 g. Moreover, in vitro release under varying pH of the optimized formulation was carried out with results that could improve the use of microencapsulated condensed tannins in animal nutrition for the biofortification of derivates.

Antimicrobial Residues

The detection of antimicrobial residues in food products of animal origin is of utmost importance. Indeed antimicrobial residues could be present in animal derived food products because of animal treatments for curative purposes or from illegal use. The usual screening methods to detect antimicrobial residues in food are microbiological, immunological or physico-chemical methods. The development of biosensors to propose sensitive, cheap and quick alternatives to classical methods is constantly increasing. Aptasensors are one of the major trends proposed in the literature, in parallel with the development of immunosensors based on antibodies. The characteristics of electrochemical sensors (i.e., low cost, miniaturization, and portable instrumentation) make them very good candidates to develop screening methods for antimicrobial residues in food products. This review will focus on the recent advances in the development of electrochemical aptasensors for the detection of antimicrobial residues in food products. The contribution of nanomaterials to improve the performance characteristics of electrochemical aptasensors (e.g., Sensitivity, easiness, stability) in the last ten years, as well as signal amplification techniques will be highlighted.

Sustainable agriculture is aimed at long-term crop and livestock production with a minimal impact on the environment. However, agricultural practices from animal production can contribute to global pollution due to heavy metals from the feed additives that are used to ensure the nutritional requirements and also promote animal health and optimize production. The bioavailability of essential mineral sources is limited; thus, the metals are widely found in the manure. Via the manure, metallic ions can contaminate livestock wastewater, drastically reducing its potential recycling for irrigation. Phytoremediation, which is an efficient and cost-effective cleanup technique, could be implemented to reduce the wastewater pollution from livestock production, in order to maintain the water conservation. Plants use various strategies for the absorption and translocation of heavy metals, and they have been widely used to remediate livestock wastewater. In addition, the pollutants concentrated in the plants can be exhausted and used as heat to enhance plant growth and further concentrate the metals, making recycling a possible option. The biomass of the plants can also be used for biogas production in anaerobic fermentation. Combining phytoremediation and biorefinery processes would add value to both approaches and facilitate metal recovery. This review focuses on the concept of agro-ecology, specifically the excessive use of heavy metals in animal production, the various techniques and adaptations of the heavy-metal phytoremediation from livestock wastewater, and further applications of exhausted phytoremediated biomass.

Полноценное, сбалансированное питание - основной фактор в формировании здоровья детей, когда в организме наиболее интенсивно протекают процессы роста и развития, формируются и созревают многие органы и системы, совершенствуются их функции. В статье приведены основные направления исследований зарубежных и отечественных ученых по лечению генетических заболеваний, таких как фенилкетонурия. Одним из приоритетных направлений в области здорового питания населения России в соответствии со Стратегией научно-технологического развития РФ до 2030 г. является развитие производства пищевых продуктов, обогащенных незаменимыми ингредиентами, специализированных продуктов детского питания, продуктов функционального назначения, диетических пищевых продуктов и биологически активных добавок. По данным ВОЗ от структуры питания на 70 % зависят здоровье и физическое развитие детей и подростков. Фенилкетонурия (ФКУ) - наследственное заболевание, вызывающее нарушение метаболизма аминокислоты фенилаланина у ребенка, одно из первых, рекомендованных ВОЗ для ранней диагностики у новорожденных. Отсутствие лечения вызывают серьезное поражение центральной нервной системы, отставание в умственном и физическом развитии. Особенностью современного этапа развития диетотерапии для детей, страдающих различными заболеваниями, в том числе наследственными, является разработка качественных функциональных продуктов питания, способствующих сохранению и улучшению здоровья ребенка за счет регулирующего и нормализующего воздействия на организм с учетом его физиологического состояния и возраста. Данные продукты можно широко использовать в практике лечебного питания не только в составе гипофенилаланиновой диеты, но и при любых заболеваниях, требующих ее соблюдения. В настоящее время единственным методом лечения ФКУ является диетотерапия, организованная с первых дней жизни с использованием специализированных смесей без фенилаланина. Из питания исключаются высокобелковые продукты растительного и животного происхождения. Целью лечебного воздействия диеты на ребенка является поддержка концентрации фенилаланина (ФА) в крови в пределах 2-12 мг на 100 мл в зависимости от возраста ребенка. Full-fledged balanced nutrition is the main factor in the formation of children's health, when the processes of growth and development are most intense in the body, many organs and systems are formed and mature, and their functions are improved. The article presents the main research areas of foreign and domestic scientists on the treatment of genetic diseases, such as phenylketonuria. One of the priority areas in the field of healthy nutrition of the Russian population in accordance with the Strategy for Scientific and Technological Development of the Russian Federation until 2030 is the development of the production of food products enriched with essential ingredients, specialized children's food products, functional products, dietary food products and biologically active additives. According to WHO, the health and physical development of children and adolescents depends on the nutritional structure by 70%. Phenylketonuria (PKN) - an inherited disease that causes impaired metabolism of the amino acid phenylalanine in a child - is one of the first recommended by WHO for early diagnosis in newborns. Lack of treatment causes serious damage to the central nervous system, a lag in mental and physical development. A feature of the modern stage of development of dietary therapy for children suffering from various diseases, including hereditary ones, is the development of quality functional food products that contribute to the preservation and improvement of the health of the child, due to the regulatory and normalizing effect on the body, taking into account its physiological state and age. These products can be widely used in the practice of therapeutic nutrition not only in the sastava of the hypophenylalanine diet, but also for any diseases requiring its observance. Currently, the only method of treating PKN is diet therapy, organized from the first days of life using specialized mixtures without phenylalanine. High-protein products of vegetable and animal origin are excluded from nutrition. The goal of the therapeutic effect of the diet on the child is to maintain the concentration of phenylalanine (FA) in the blood in the range of 2-12 mg per 100 ml, depending on the age of the child.
