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.

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.

Необходимость длительного хранения большого количества сахарной свеклы на сахарных предприятиях приводит к высоким потерям свекломассы и сахара, а также к снижению технологических качеств сырья. Для снижения потерь сырья при хранении широкое распространение получили химические способы защиты, для оценки эффективности которых не выработано единого комплексного критерия. С целью разработки такого критерия исследована эффективность влияния обработки биологически активными препаратами Гембар, Полидез Плюс и КСД-2 на сохранность сахарсодержащего сырья. Для исследований использовали корнеплоды сахарной свеклы, выращенной в Республике Беларусь, хорошего технологического качества, которые обрабатывали одним из препаратов – КСД-2 концентрацией 5%, Гембар и Полидез Плюс концентрацией 0,15% при расходе 2 дм3 рабочего раствора на 1 т свеклы – и закладывали на краткосрочное, среднесрочное или длительное хранение в производственном кагате. Исследования фитопатологических показателей обработанных препаратами образцов корнеплодов и контрольных – необработанных корнеплодов и расчет потери массы и сахарозы после различной продолжительности хранения проводили в течение двух производственных сезонов. Установлено, что обработка позволяет снизить содержание гнилой массы и массу ростков соответственно на 73–100% и 81% при обработке препаратом Гембар, на 40–42% и 54% при обработке Полидезом Плюс, на 87–100% и 90–92% при обработке КСД-2; уменьшить потери массы свеклы и среднесуточные потери сахарозы соответственно на 6–46% и 22,2–53,3% при обработке препаратом Гембар, на 6–77% и 5,6–29,4% при обработке Полидез Плюс, на 19–76% и 33,3–69,2% при обработке КСД-2 в зависимости от продолжительности хранения и производственного сезона. Также установлено, что в контрольном образце содержание сахарозы в зависимости от продолжительности хранения снижалось, % к массе свеклы, на 0,19 при краткосрочном хранении, на 0,48 при среднесрочном и на 0,83 при длительном хранении, но после обработки препаратом КСД-2 образцы корнеплодов потеряли соответственно 0,05; 0,19 и 0,47% сахарозы к массе свеклы, что в 3,8; 2,5 и 1,8 раза меньше по сравнению с контролем. На основе результатов исследований для оценки эффективности влияния применяемого препарата на снижение деградации сахарной свеклы при различной продолжительности хранения (сохранность технологических качеств) предложено использование двух комплексных показателей – индекса технологического качества сахарной свеклы и индекса сохранности сахарной свеклы. По разработанным формулам комплексных показателей рассчитаны индексы сохранности сахарной свеклы для исследованных вариантов хранения. The need for long-term storage of a large amount of sugar beet at sugar enterprises leads to high losses of beet pulp and sugar, as well as to a decrease in the technological qualities of raw materials. To reduce the loss of raw materials during storage, chemical methods of protection have become widespread, for evaluating the effectiveness of which no single complex criterion has been developed. In order to develop such a criterion, the effectiveness of the effect of treatment with biologically active preparations Gembar, Polydez Plus and KSD-2 on the safety of sugar-containing raw materials was studied. For the research, we used sugar beet roots grown in the Republic of Belarus, of good technological quality, which were treated with one of the preparations – KSD-2 with a concentration of 5%, Gembar and Polydez Plus with a concentration of 0,15% at a consumption of 2 dm3of the working solution per 1 ton of beet – and laid for short-term, medium-term or long-term storage in a production cahat. Studies of phytopathological parameters of samples of root crops treated with preparations and control samples of untreated root crops and calculation of weight loss and sucrose after different storage periods were carried out during two production seasons. It was found that the treatment allows to reduce the content of rotten mass and the mass of sprouts respectively by 73–100% and 81% when treated with Gembar, by 40–42% and 54% when treated with Polydez Plus, by 87–100% and 90–92% when treated with KSD-2; to reduce beet mass losses and average daily sucrose losses, respectively, by 6–46% and 22,2–53,3% when treated with Gembar, by 6–77% and 5,6–29,4% when treated with Polydez Plus, by 19–76% and 33,3–69,2% when processing KSD-2 depending on the duration of storage and the production season. It was also found that in the control sample, the sucrose content, depending on the duration of storage, decreased, % by weight of beet: by 0,19 for short-term storage, by 0,48 for medium-term, and by 0,83 for long-term storage, but after treatment with KSD-2 the root crop samples lost 0,05; 0,19 and 0,47% by weight of beet respectively, which is 3,8; 2,5 and 1,8 times less compared to the control. Based on the research results, the use of two complex indicators – the index of technological quality of sugar beet and the index of safety of sugar beet-is proposed to assess the effectiveness of the effect of the drug used on reducing the degradation of sugar beet with different storage periods (preservation of technological qualities). According to the developed formulas of complex indicators, the indices of the safety of sugar beet for the studied storage options are calculated.

Aim. Assess and analyze the structure of agricultural production and the total amount of losses during its transportation, sale and processing. Materials and Methods. The scientific research was based on an assessment of the reported aggregated statistical data on the volume of agricultural production in Russia. Methods of graphic, statistical analysis, methods of analogy and comparison, genesis and synthesis of scientific knowledge were used in the work. Results. The gross volumes of agricultural production were calculated (280 million rubles), the volumes of products sold (8.25 trillion rubles) aimed at personal consumption were determined (81 million rubles), and the total losses of products in the process of their sale and consumption, and transportation to the final consumer were calculated (48 million tons). It was concluded that manufacturers today are actually aimed at exporting raw materials, without its subsequent processing and storage due to the lack of established logistics routes and the necessary capacities for its long-term storage. Recommendations were developed for the development of infrastructure for long-term storage and subsequent processing of agricultural products. Conclusion. Conclusions are drawn about the need to revise the existing system of logistics supplies and transportation of agricultural products from the field to the storage facility or producer. For the successful intensification of the existing process of internal processing of agricultural products, it is necessary to increase the storage and freezing capacities of raw materials.
