Tomato Processing

The article analyzes the biological value of secondary products of tomato processing, namely tomato seeds, which, for the most part, is not considered as an object of processing. The use of secondary raw materials formed in the production of tomato products as a source of biologically active substances with their subsequent use in food technology is proposed. The results of theoretical and experimental studies of the biological value of tomato seeds. It has been found that tomato seeds have a high nutritional and biological value due to the high concentration of proteins, lipids, and carbohydrates. Accordingly, this value complies with modern recommendations on healthy diet for the population. Also, tomato seeds are rich in polyunsaturated fatty acids, phospholipids, macro- and micronutrient elements, vitamin E, and fiber. However, its nutritional value is substantially reduced by natural biologically active anti-alimentary substances, namely proteinase inhibitors. A first experimental is antinutrients tomato seeds.  А number of trypsin inhibitors of tomato seeds use micronating processing , a significant reduction has been achieved. The use of hydrothermal and micronization treatment of tomato seeds to reduce the activity of trypsin inhibitors is proposed. Hydrothermal treatment for 40 min at a water temperature of 90..100°C reduced trypsin inhibitory activity by 1..3% from baseline. Thus, when you stand micronating processing maturity during 60s reducing  trypsin inhibitors is about 34 % and for biological maturity is 28.8%. It was found that  technology tomato seeds processing allows to obtain a biologically valuable product, which is mainly represented by lipid up to 40%, as well as significant content of protein substances, carbohydrates and fibre. The purpose of this paper is the study of chemical composition and biological value of secondary tomato resources, namely tomato seeds, as well as researching the possibility of its application in food technology. It is also concerned with determination of quantitative and qualitative composition of anti-nutrients of tomato seeds and selection of ways to decrease the activity of anti-nutrients of tomato seeds.

Background. The deficiency of essential nutrients in the human body is the root cause of reduced efficiency, general resistance of the body to various diseases. That is an urgent problem in the context of the spread of coronavirus infection. In this regard, the search for opportunities to meet the needs of the population in food products that contain biologically active substances (BAS) through the use of high-value and at the same time available plant raw materials is extremely important. Marigolds attract special attention among such raw materials. The aim of the work is to study the chemical composition and evaluate the consumer properties of Tagetes L. varieties, zoned in the Kiev region, to prove the possibility of increasing the biological value of pasta by adding to their recipe powder from marigold inflorescences. Materials and methods. The object of research is pasta of B group (noodles). Inflorescences of marigolds of different varieties gathered during the flowering period in July-September 2019–2020 in the territory of Vasylkiv and Obukhiv districts of Kyiv region, Ukraine were used as enriching plant raw materials. The quality of finished pasta was assessed by organoleptic and physicochemical indexes (moisture content and titratable acidity). The content of mineral elements in the fine powder of marigold inflorescences was determined on the EXHERT-3L device, the quantitative composition and BAS identification – by spectrophotometric analysis on the device Specord-200 Analytic Jena UV-vis. The integrated quality index of pasta products was calculated taking into account the importance factors of individual indexes. Results. Comparing the obtained results, we can state that all the studied varieties – Gold Kopfen, Orange Flame, Hawaii, Equinox are characterized by high biological value, regardless of the area of collection. As a result of calculated and experimental studies it was determined that the addition of 7 % of the supplement does not provide the required supply of vitamins and minerals. Replacing the flour in the recipe by 20 % significantly improves the mineral composition, but deteriorates the taste and aromatic properties of pasta. The most optimal and rational amount of added additive is 15 %, as it improves the organoleptic properties of pasta and enriches their BAS. Conclusion. The usage of non-traditional vegetable raw materials, in particular powder from marigold inflorescences, which is rich in biologically active substances, allows not only to expand the range, improve the quality of finished products, but also increase the biological value of the product. The optimal amount of additive –powder from marigold inflorescences, was defined. It is 15 % by weight of flour in the production of noodles. This concentration allows not only to improve the organoleptic properties, but also to increase the content of biologically active substances – vitamins, micro- and macronutrients. The usage of non-traditional natural raw materials (powder from marigold inflorescences) allows to abandon artificial colorsand give the finished pasta a pleasant colorand aroma.

Currently, the development of rational technologies for processing secondary resources of the fish processing industry is of considerable interest in order to obtain a wide range of food, feed, technical, medical products and biologically active additives on their basis. Of particular interest is the technology developed by the authors for obtaining dry food fermentolizates from secondary products of cutting pink salmon and silver carp. In the course of the experiment, it was found that the protein zones for the samples are mainly represented by low-molecular weight easily digestible proteins with m. m. from 13 to 33 kDa. The evaluation of the ratio of amino acids compared to the FAO standard showed that in the human body, the amino acids of fermentolizates are able to be utilized by 68-80%, which proves their high biological value. Own experimental data indicate a high availability and degree of destruction of proteins of fermentolizates by enzymes of the human gastrointestinal tract, which is from 92.39 to 96.87%. Thus, fermentopathy from secondary cuts of fish are high-value protein products.

Abstract The enterprises processing plant raw materials generate a fairly large amount of waste (secondary products), which can play an important role in solving food, environmental, and energy problems. This work improves the technology for the production of canned quince compote using a two-stage microwave heating of fruits and fruits filled with syrup prepared from infusion obtained from secondary products of cutting and peeling. It has been established that two-stage heating of fruits and microwave treatment of fruits filled with syrup in a glass jar promote an increase in the initial temperature of the product in the jars before sealing and thereby reduces the heat treatment modes. The infusion obtained from the secondary products of the heat-treated fruits provides a significant increase of biologically active components in the finished product. The experimental studies were used to construct a mathematical model for calculating the initial temperature of the product before sterilization, which makes it possible to establish intensive pasteurization modes. New modes of pasteurization of quince compote in various containers have been established. Physicochemical studies confirm the high quality of the finished product in terms of the content of biologically active components.

Radical Chain Reaction

Catalytic enantioselective synthesis of tetrahydrofurans, which are found in the structures of many biologically active natural products, via a transition-metal catalyzed-hydrogen atom transfer (TM-HAT) and radical-polar crossover (RPC) mechanism is described herein. Hydroalkoxylation of non-conjugated alkenes proceeded efficiently with excellent enantioselectivity (up to 94% ee) using a suitable chiral cobalt catalyst, <i>N</i>-fluoro-2,4,6-collidinium tetrafluoroborate, and diethylsilane. Surprisingly, absolute configuration of the product was highly dependent on the steric hindrance of the silane. Slow addition of the silane, the dioxygen effect in the solvent, thermal dependency, and DFT calculation results supported the unprecedented scenario of two competing selective mechanisms. For the less-hindered diethylsilane, a high concentration of diffused carbon-centered radicals invoked diastereoenrichment of an alkylcobalt(III) intermediate by a radical chain reaction, which eventually determined the absolute configuration of the product. On the other hand, a more hindered silane resulted in less opportunity for radical chain reaction, instead facilitating enantioselective kinetic resolution during the late-stage nucleophilic displacement of the alkylcobalt(IV) intermediate.

The expediency of using the probiotic drug Biolax-U in the rations of lactating and dry cows of Black-and-White breed has been studied and scientifically proved. The influence of this drug on the morphological and biochemical parameters of animal blood has been determined. The composition of the probiotic drug Biolax-U consists of eight strains of a balanced complex of living lactic acid bacteria, yeast and actinomycetes, as well as biologically active substances. For experimental studies conducted on 2 groups of cows have been selected by the method of pairs-analogs, the influence of feeding of feed have been prepared with the use of the microbiological drug with probiotic action Biolax-U on feed consumption, morphological and biochemical changes in blood has been studied. Analysis of the rations of cows indicates that the content of calcium, phosphorus, magnesium, sulfur and trace elements such as manganese, copper, zinc and cobalt in the feed has been reduced. It has been found by studies that the use of probiotic drug Biolax-U had the positive influence on the feed intake, digestibility and better assimilation of feed nutrients and contributed to the improvement of blood morphological and biochemical parameters. For example, in animals of the experimental group hemoglobin has increased by 3,6 % (Р < 0,05), red blood cells by 10,1 (P ≤ 0,05), the content of leukocytes by 4,43, carotene by 9,6, glucose by 3,4; reserve alkalinity by 15,6, calcium by 19,4 (P ≤ 0,01), and phosphorus by 18,4 % compared with the control group of animals. During the lactation significantly improved hematological parameters including alkalinity reserve by 5,11 %, calcium level by 11,1, phosphorus by 8,6, hemoglobin by 14,2 %, the content of erythrocytes by 12,3, leukocyte by 3,86, and carotene 11,1 % against the parameters of animals of control group. The improvement of morphological and biochemical parameters of blood of cows indicates about stimulating effect on hematopoiesis and the general clinical condition of animals that contributes to the improvement of metabolic processes when using feed prepared with the use of microbiological drug with probiotic action Biolax-U.

Endothelial Cell Migration

Platelet-activating factor (PAF) is a phospholipid mediator that belongs to a family of biologically active, structurally related alkyl phosphoglycerides. PAF acts via a specific receptor that is coupled with a G protein, which activates a phosphatidylinositol-specific phospholipase C. In this review we focus on the aspects that are more relevant for the cell biology of the cardiovascular system. The in vitro studies provided evidence for a role of PAF both as intercellular and intracellular messenger involved in cell-to-cell communication. In the cardiovascular system, PAF may have a role in embryogenesis because it stimulates endothelial cell migration and angiogenesis and may affect cardiac function because it exhibits mechanical and electrophysiological actions on cardiomyocytes. Moreover, PAF may contribute to modulation of blood pressure mainly by affecting the renal vascular circulation. In pathological conditions, PAF has been involved in the hypotension and cardiac dysfunctions occurring in various cardiovascular stress situations such as cardiac anaphylaxis and hemorrhagic, traumatic, and septic shock syndromes. In addition, experimental studies indicate that PAF has a critical role in the development of myocardial ischemia-reperfusion injury. Indeed, PAF cooperates in the recruitment of leukocytes in inflamed tissue by promoting adhesion to the endothelium and extravascular transmigration of leukocytes. The finding that human heart can produce PAF, expresses PAF receptor, and is sensitive to the negative inotropic action of PAF suggests that this mediator may have a role also in human cardiovascular pathophysiology.

This paper presents the findings of experimental studies of the physical and mechanical properties of wood-filled composites based on polylactide (PLA) and vegetable filler in the form of wood flour (WF) thermally modified at 200-240 °C. It also reveals the dependence of the tensile strength, impact strength, bending elastic modulus, and density of composites on the amount of wood filler and the temperature of its thermal pre-modification. We established that an increase in the concentration of the introduced filler and the degree of its heat treatment results in a decrease of the tensile strength, impact strength and density of composite materials, while with a lower binder content, thermal modification at 200 °C has a positive effect on bending elastic modulus. We also found that 40 % content of a wood filler heated to 200 °C is sufficient to maintain relatively high physical and mechanical properties of composite materials. With a higher content of a wood filler, the cost can be reduced but the quality of products made of this material may significantly deteriorate. However, depending on the application and the life cycle of this product, it is possible to develop a formulation that includes a high concentration of filler.

Проведена сравнительная оценка хлебопекарных смесей (ХПС) Ливенка и Амарантус, включающих биоактивированное зерно пшеницы и ржи и биоактивированные злаковые культуры и амарантовую муку соответственно, и хлеба на их основе. Исследованы химический состав, биологическая и энергетическая ценность ХПС и выпеченных на их основе образцов зернового хлеба Ливенский и Амарантус. Установлено, что ХПС Амарантус и хлеб Амарантус отличаются несколько большим содержанием белка, кальция, лизина по сравнению с ХПС Ливенка и хлебом Ливенский. Однако по количеству пищевых волокон и витаминов ХПС с амарантовой мукой и изделия на ее основе несколько уступают образцам, приготовленным без добавки амарантовой муки. Внесение амарантовой муки в дозировке 5,5% взамен части ржаной муки незначительно повышает энергетическую и биологическую ценность ХПС и хлеба на ее основе. Установлено, что ХПС Ливенка и Амарантус относятся к функциональным пищевым ингредиентам за счет содержания значимого количества биологически активных веществ, а изделия на их основе – к функциональным пищевым продуктам. Comparative evaluation of baking mixes (BM) of Livenka and Amarantus, including bioactivated grains of wheat and rye and bioactivated cereals and amaranth flour, respectively, and bread on their basis was carried out. Chemical composition, biological and energy value of BM and baked on their basis samples of grain bread Livenskiy and Amarantus were investigated. It is established that the BM Amarantus and bread Amarantus are slightly high content of protein, calcium, lysine, compared with BM Livenka and bread Livenskiy. However, the number of dietary fibers and vitamins BM with amaranth flour and products on it based are concede to samples a little prepared without the addition of amaranth flour. The introduction of amaranth flour in a dosage of 5,5% instead of a portion of rye flour slightly increases the energy and biological value of BM and bread on it based. It was found that the BM Livenka and Amarantus are functional food ingredients due to the content of a significant amount of biologically active substances, and products on their based – to functional foods.
