Evaluation of Physical and Chemical Parameters According to Energetic Willow (Salix viminalis L.) Cultivation

The aim of this study was the investigation of the effect of growth conditions of energy willow (Salix viminalis L.) on its physical and chemical parameters towards lignocellulosic biofuels. This work is linked to the global trend of replacing fossil fuels (coal, oil, natural gas) with energy and renewable fuels. This energy transition is dictated by the reduction of the human-induced greenhouse effect (to the greatest extent by industrial development). Changing from traditional to renewable energy sources results in industry becoming less dependent on fuels whose sources are beginning to run out, and in energy processing being broken down into smaller sectors with greater flexibility to change and less susceptibility to failure. The use of lignocellulosic raw materials such as wood, straw, food industry waste, wood, and post-consumer products such as old furniture for energy purposes allows the use of substances which bind the greenhouse gas carbon dioxide in their cellular structure during growth. In order to optimise the costs of producing such energy and minimise its impact on the environment, these plants should be located as close as possible to the source of raw materials. One of the most important characteristics for the profitability of energy production from woody biomass is a high biomass yield. For this purpose, the raw material used for this study was energy willow (Salix viminalis L.) seedlings, which are often used for energy crops. Due to the moisture-loving nature of the substrate, the effect of the addition of the active substance prednisonum as a catalyst for water adsorption from the substrate was investigated. In order to determine the substances formed during the thermal decomposition of energy willow (Salix viminalis L.) wood, a pyrolysis process was carried out at 450 °C using pyrolysis gas chromatography mass spectrometry (PY/GC-MS).

Abstract Ensuring the health of the population is a task of the national importance. One of the most significant factors that determine a person’s health and performance is nutrition. In a highly competitive environment, manufacturers face one of the main tasks - the creation of new competitive products with high-quality indicators and preventive properties. Improving the quality of baked goods is one of the problems of bakery production. The article deals with the theoretical possibility and practical feasibility of using spelt flour in the production of baked goods with improved consumer benefits. Spelt flour is a valuable raw material for the production of bakery and flour confectionery products of increased nutritional and biological value. The use of whole grain spelt flour in the recipe of wheat bread allows creating products for dietary and curative and preventive purposes. In the course of the work, experimental baking of wheat bread with different dosages of wheat and spelt flour was carried out. Samples of wheat bread with a different combination of spelt and wheat flour of the highest grade in the ratios of 5:95; 10:90; 15:85% were studied. The research was conducted in the laboratory of the Department of Technology of Storage and Processing of Agricultural Raw Materials and Public Catering, Volgograd State Agrarian University. The results of the influence of spelt flour application on the organoleptic and physical and chemical parameters of wheat bread are presented. As a result of the conducted research, the possibility of producing wheat bread using spelt flour was established, and the optimal dosage of spelt and wheat flour which allows one to obtain bread with high organoleptic and physical and chemical parameters was identified.

The genus Dragonhead (Dracocephalum L.) includes 72 species of essential oil-bearing plants belonging to the Lamiaceae family. Many of them have long been used in a folk medicine of different countries. Moldavian dragonhead (D. moldavica L.) has been identified as the most promising species for the complex phytochemical research since it was successfully introduced in the climatic conditions of the Ukrainian forest-steppe zone and due to the presence of its various botanical forms and varieties. The aim of this study was the phytochemical analysis of the main groups of secondary metabolites in the herb of violet-flowered form of Moldavian dragonhead (D. moldavica L.) under its cultivation in Ternopil region (Ukraine). The herb of the plant was harvested in July of 2018‒2019 years during the flowering period. The essential oil was obtained from the plant raw material by the hydrodistillation. Such physical and chemical parameters of the essential oil as a relative density, refractive index, optical rotation, acid number and solubility in ethanol were studied. The method of thin layer chromatography (TLC) was used to determine the specific sequence of bands in the chromatograms of essential oil. The method of high-performance thin-layer chromatography (HPTLC) was used for the identification of phenolic compounds in the herb. The component composition of polyphenols was determined by the high performance liquid chromatography (HPLC). The specific physical and chemical parameters as well as the «chromatographic profile» of essential oil have been established. The main compounds of the polyphenolic nature were revealed by the chromatographic methods. In particular, rosmarinic and caffeic hydroxycinnamic acids were identified in the methanol extract of herb by the HPTLC method. The HPLC analysis of phenolic compounds in the 70% ethanol extract of raw material established that rosmarinic acid was its main polyphenol. It was found the decreasing of polyphenol contents in the D. moldavica herb in such direction: rosmarinic acid (3.01%) > apigenin-7-О-glucoside (0.67%) > apigenin (0.29%) > caffeic acid (0.28%) > luteolin-7-О-glucoside (0.13%)> hyperoside (0.12%) > ferulic acid (0.09%) > chlorogenic acid (0.08%). The obtained data could be used for planning pharmacological studies of the phytosubstances developed from the Moldavian dragonhead herb.

. The influence of a food additive“Magneftofud” (nanopowder of double oxide of two- and trivalent Ferum) on physical and chemical parameters, functional and technological properties of model beef minced meat have been studied. Also, their organoleptic parameters and the output of ready steaks made from them were investigated. Food additive “Magnetofood” was added to the beef minced meat in the amount of 0.05–0.15% to the mass of meat raw material. The water-binding ability was determined by the method of pressing; degree of oxidation by means of peroxide and acid numbers; output of the finished product and organoleptic indicators – by standard and commonly accepted methods; digestion of proteins of steaks – by the method of Pokrovsky A.A. and Yertanova E.D. It has been determined that due to the nanosize of Ferum oxide , a significant specific volume, developed active surface, affinity for proteins, thermal stability, the additive “Magnetofood” has antioxidant, sorption, complexing, structure-forming, stabilizing, water-binding, water and fat-retaining properties. Thus, the investigated additive contributes to the formation of new functional and technological indicators of beef meat systems and the improvement of consumer characteristics of the finished products obtained from them. The input of "Magnetofood" food additive in beef minced meat improves the organoleptic and functional-technological parameters compared to control: the moisture-binding capacity increases by 12.0–12.8%; output of finished products - by 1,5–4,5%. The growth of the total effect of digestion of proteins of prepared steaks (in 1,17-1,65 times) have been noted; reduction of the acid number (by 3,0–4,0%) and peroxide number (by 0,09–0,12 mmolol/kg). The results of the studies allowed to determine the rational amount of food supplement “Magnetofood”, it is 0.15% to the mass of meat raw materials.

Sustainable Consumption And Production

This review paper examines the past, present, and future of sustainable consumption and production (SCP). The history of the Sustainable Development Goal No. 12 (i.e., to ensure sustainable consumption and production patterns) is presented and analyzed. A definition of the sustainable consumption is given and the role of education is explained. The present status and existing trends of SCP are introduced by analyzing unsustainable behavior and the existing dilemma, namely sustainable growth or degrowth. A very broad range of methods is used for measuring and evaluating SCP within sustainable development. To forecast the future of SCP, important trends are presented. The future development of SCP will follow several megatrends and it will require reduced personal and collective consumption (degrowth). Energy usage in buildings, renewable energy sources, and energy storage will be important in that respect. Transportation emissions will continue to be lowered. Waste, especially food waste, shall be reduced, and consumer products shall become more durable. All waste must be collected and separated to be reused. SPC is elaborated in view of the two approaches—Industry 4.0 (smart factory), and the “Sixth Wave” evolution. Net-zero greenhouse gas emissions, resource efficiency, and zero waste will be at the forefront of future activities. A circular economy requires extension of product lifetimes, and the reuse and recycling of products. Reducing emissions, pollution and specific energy, water, and raw material usage (especially critical raw materials), as well as the role of digitalization, will be important.

The book under review is a concise but fairly in-depth study of the prospects for export diversification from the Less Developed Countries (henceforth labeled as LDCs) particularly to Developed Countries (henceforth labeled as OCs). Given the multiple problems faced by the LOCs in exporting to the OCs - protectionist policies with regards to manufactured exports, volatility of prices obtained for raw material exports, etc. - the study analyses the potential for following an intermediate route. The important issues in the export of semi -processed and wholly processed raw materials are discussed. 111ese issues range from the problems and potentials for the location of processing facilities in the LOCs to the formulation of appropriate policies to encourage an export of processed goods rather than raw materials. Such policies will be useful both in solving the balance of-payments problems of the LDCs and in attaining the goal of the Lima Declaration and Plan of Action on Industrial Development and Co-operation, that called for 2S percent of world industrial production to be located in the LOCs by the year 2000.
