The basic information about functional mixtures is outlined, options for compositions and recommendations for use in baking in mass production are proposed. The characteristic of microbiological, physical and chemical indicators is given, and the results of toxicological studies of dry functional mixtures with fruit and berry powders are given. High-calorie, medium-calorie, and low-calorie composite mixtures have been developed for the centralized production of yeast dough. Dry functional mixtures can be produced according to regulatory documents: TU 9161-004-51926638-11 and TI to TU 9161-004-51926638-11. A patent of the Russian Federation No. 2602629 was obtained for dry functional mixtures with fruit and berry powders. The technological scheme for obtaining a dry functional mixture consists of the following operations: sifting, dosing of prescription components in predetermined proportions: dry egg-milk mixture in the amount of 56.2-61.6% sugar – 20.0-24.3% and salt – 14.1-17.2%. Xanthan (1.06-2.43%) or guar (4.25-5.30%) and fruit and berry powders (1.0-1.5%) are introduced as additional raw materials. Then mixing is carried out, preparation for implementation. The resulting mixture is portioned and packaged in paper bags. Fruit and berry powders were prepared from rose hips, aronia, nettle, bananas, apples and carrots. According to microbiological studies, the degree of contamination during storage during the year corresponds to SanPiN 2.3.2.1078-01, which makes it possible to produce dry functional mixtures with fruit and berry powders for long-term storage. They can be stored in a dry, well-ventilated room in compliance with sanitary rules, with a relative humidity of 65-70% and a temperature of 18-20 °C from 0 to 12 months. It was found that during storage for 12 months. in hermetically sealed paper bags, no powder quality changes were observed. Bakery products made using these mixtures can be recommended for medical, preventive and gerontological nutrition.

Accelerated carbonation is a carbon utilization option which allows the manufacturing of useful products, employing CO2-concentrated or -diluted emission sources and waste streams such as industrial or other processing solid residues, in a circular economy perspective. If properly implemented, it may reduce the exploitation of virgin raw materials and their associated environmental footprint and permanently store CO2 in the form of Ca and/or Mg carbonates, thus effectively contributing to climate change mitigation. In this perspective article, we first report an overview of the main mineral carbonation pathways that have been developed up to now, focusing on those which were specifically designed to obtain useful products, starting from different alkaline feedstocks. Based on the current state of the art, we then discuss the main critical issues that still need to be addressed in order to improve the overall feasibility of mineral carbonation as a CCUS option, as well as research needs and opportunities.

The urgency of solving environmental problems of disturbed territories is obvious in connection with the accumulation of a huge amount of waste from mining and metallurgical industries, deposited in slime and tailings dumps, overburden dumps, slags and substandard raw materials. Environmental rehabilitation of such territories is determined by both the possible long-term existence of such objects and the prospect of their reuse. In this regard, the use of new geosynthetic materials, the most promising and effective method of restoring ecological characteristics of the areas of violations of land, based on the implementation of the principle of least possible scope of application of topsoil and vegetation established, carrying out sanitary-hygienic function, contributes to the improvement of the environment in the areas of enterprise functioning. The article presents the results of applied research on the reclamation of the horizon the shortage of topsoil, or when you use the fertile layer, exposed to long-term storage in dumps. And the planting of grass vegetation on the recultivated surface that corresponds to the regional nature of environmental optimization measures, taking into account zonal features, will ensure the creation of sod that stops the processes of deflation and water erosion.

The article is devoted to the study of long-term storage of silicate brick in stationary water conditions on its strength and phase composition. The relevance of these studies is due to the fact that there are a lot of opinions that silicate materials have low water resistance which significantly limits their application range and reduces their popularity among builders. It has been found that after nine years storage in water and followed drying the silicate brick’s strength is practically equal to the initial strength. The data on the phase composition of newgrowths in silicate brick newly made in different production periods and the phase composition of silicate hydrates of bricks water conditioned are presented in the article. Comparison of the X-ray and differential thermal analyzes results of silicate bricks samples after 9 years of water conditioning and samples of newly made silicate bricks showed that highly basic calcium silicate hydrates predominate in a newly made sample, and in a 9-year-old sample silicate hydrates are mainly represented by tobermorite, while the total content of the СSH phase is the same. The content of calcium hydroxide in a newly made sample is higher but this may be due to the completeness of Ca(OH)2 binding in a particular sample but not to its leaching. The fact that leaching of Ca(OH)2 from silicate brick in still water does not occur also can be proved because the water of brick samples storage does not turn pink when phenolphthalein is added. These results allow us to conclude that long-term storage of silicate products in still water does not have any effect on the deterioration of silicate bricks.

It is important to correctly determine the stage of harvesting. To establish full ripeness, it is necessary to accurately identify the period when plastic substances stop entering the grain. All this is necessary for the formation of high-quality grain. Due to the long-term storage of grain, its germination decreases, as there are violations in the processes of metabolism. Therefore, during the storage period, it is necessary to control the quality of the seed material. The purpose of the research was to determine the impact of harvesting time and long-term storage of grain for obtaining seed material with high indicators of yield and sowing qualities. The experimental part of the work was carried out on the experimental field and in the laboratory conditions of the FGBNU FANC North-East in 2015-2020. From each variant of the experiment, 1 kg of seeds of the 2015 harvest were stored. Under laboratory conditions, the germination energy and laboratory germination capacity of the seeds were tested. In 2020, field germination and yield qualities of seeds were studied in three-fold repetition on meter plots. During the years of research, changes in the sowing qualities of seeds obtained during storage in 2015 were noted. Seeds from crops that were harvested at the onset of the full ripeness phase and at a grain moisture content of 17 … 20 %, (1), the indicators of germination energy and germination were the highest than when harvested at a later time. A significant decrease in indicators was noted in the cleaning options for 10 and 15 days later than the optimal one. The study of the influence of the harvest year and the duration of seed storage showed that seeds 1 and 2 of the harvest period in 2015 provide a higher yield than seeds 3 and 4 of the harvest period. The use of late-harvest seeds in sowing leads to a decrease in the weight of 1000 grains and the nature of the grain.

Along with the development of agroecosystems, environmental friendliness of agricultural and industrial technologies for long-term storage of agricultural products is being formed as a result of cognitive technologies development, including innovations in biotechnologies. Achieving the biological safety of bulk unrefined sunflower oil is based on the addition of an unconventional antioxidant phyto-raw material to it - stinging nettle, which slows down oxidative processes. In order to prevent oil contamination, the optimal dose of ionizing radiation for the nettle treatment is established - up to 1.5 kGr, which ensures microbiological safety and antioxidant activity (AOA) at the level of 0.763 + 0.016 mMeq, comparable to AOA in the untreated nettle samples after 3 months. After 52 days of storage, the acid number was in the range of 0.99-1.15 mg KOH / g, the peroxide number was 5.09-5.16 mmol active oxygen / kg. Adding 0.5-1.0 wt. % nettle powder to the oil ensures the compliance of organoleptic parameters with the established requirements - transparency, taste and smell. Adding 1.0 wt. % nettle powder to the oil slows down the filtration process of the resulting suspension. The practical relevance of the study is determined by the verification of the research results to prolong the oil shelf life by adding environmentally friendly phyto-raw materials to it.
