Introduction. Parmelia perlata is a widespread lichen that belongs to the Parmeliaceae family. In Ayurvedic medicine thalli of Parmelia perlata are used for the treatment of a series of diseases of different genesis. Literature data contain information that the representatives of Parmeliaceae family show a wide spectrum of biological activity, in particular, possess anti-bacterial, cardiotonic, spasmolytic, antioxidant and other types of activity.The aim of the study – to learn the mineral composition of parmelia perlata thalli of Kazakh and Russian production.Materials and Methods. For the study of the composition of micro- and macroelements by the atomic-absorption spectroscopy method Parmelia perlata thalli of Kazakh and Russian production were used.Results and Discussion. As a result of the study the content of 19 mineral elements in Parmelia perlata thalli of Kazakh and Russian production was determined. The dominating elements in both studied objects were calcium and silicon. The content of calcium in the raw material of Kazakh production comprised 2270.00 μg/100 g, and in the raw material of Russian production – 1938.00 μg/100 g. The content of silicon in the raw materials studied comprised 1815.00 μg/100 g and 1619.00 μg/100 g respectively. The content of iron and magnesium in both samples was almost identical, while the content of sodium and potassium in the raw material of Russian production was 1.5 times higher than in the raw material of Kazakh production. Both samples were found to accumulate magnesium and zinc in quite high concentration. The content of heavy metals in both raw material samples was within the limit of maximum permissible concentration for medicinal plant material and food products according to the requirements of the current legislation.Conclusions. The obtained results can be used at working out medicines on the basis of Parmelia perlata thalli and the quality control methods for the raw material.

BACKGROUND: A possible reduction in stocks of medicinal plant raw materials of Thymus serpyllum L. and Thymus vulgaris L. leads to the need to expand the raw material base of the official medicinal plants with using of endemic species of the flora of Kazakhstan, in particular, Thymus rasitatus Klokov, and Thymus eremita Klokov. AIM: The aim of the study was to study the possibility of using 70% ethanol extracts of T. rasitatus and T. eremita as antimicrobial agents. MATERIALS AND METHODS: The aerial parts of T. rasitatus and T. eremita were extracted with 70% ethanol using ultrasound assisted extraction. The qualitative and quantitative analyses of the 70% ethanol extracts were determined using the liquid chromatography-detection-ESI-mass spectrometry-(MS)/MS technique. The study of the antimicrobial activity of these extracts was performed for eight strains of Gram-positive bacteria, six strains of Gram-negative bacteria, and four cultures of fungi. RESULTS: Chromatographic analysis of hydroalcoholic extracts of both investigated Thymus species showed very similar phenolic compounds composition. In both cases, the major components are luteolin-7-O-glucoside and rosmarinic acid. About 70% ethanol extracts of T. rasitatus and T. eremita have a broad spectrum of antimicrobial activity, exhibit the bactericidal or bacteriostatic activity against all tested bacteria and fungi at concentration range of 0.0195–20 mg/ml, but differ in their potency against tested strains of microorganisms. CONCLUSION: About 70% ethanol extracts of T. rasitatus and T. eremita, endemic plants in the flora of Kazakhstan, can be considered as potential drugs with a wide spectrum of antimicrobial activity. The results of chromatographic analysis could be used for drug standardization.

The problems of processing spent adsorbents with a high concentration of chemisorbed chlorine-containing compounds for their reuse are studied in this article. The genesis of the phase composition and morphology at all technological stages of thermochemical regeneration of the spent adsorbent - Axstrap-860 by means of alkaline modification with a combined solution of sodium and potassium hydroxides has been tested by diffractometry and elemental analysis. The results show that the formation of a layer with an increased concentration of alkali metals in the form of the corresponding carbonates and NaOH on the surface of the granules and in the volume of sodium and potassium aluminates provides adsorption of HCl, which are slightly inferior to the fresh adsorbent. The conditions for the removal of halogen-containing substances from technogenic raw materials with the subsequent isolation of useful products have been optimized: (1) crystalline NaCl intended for the preparation of electrolyte for electrode boilers and steam generators; (2) a mixture of chlorides and hydroxochlorides of aluminum tested in the process of coagulation purification of turbid natural and waste waters; (3) pseudoboehmite for the production of an adsorbent-desiccant and the synthesis of magnesium-aluminum spinel using the technology of destruction-epitaxial transformation, and a promising carrier for catalysts for steam reforming of hydrocarbons.

Biodiesel is defined as a fuel which may be used as pure biofuel or at high concentration in mineral oil derivatives, in accordance with specific quality standards for transport applications. The main raw material used for biodiesel production is rapeseed, which contains mono-unsaturated acids (about 60%) and also poly-unsaturated fatty acids (C 18:1 and C 18:3) in a lower quantity, as well as some undesired saturated fatty acids (palmitic and stearic acids). Other raw materials have also been used in research and the industrial production of biodiesel (palm oil, sunflower oil, soybean oil, waste plant oil, animal fats, etc). The historical background of biodiesel production, installed industrial capacities, as well as the Directive of the European Parliament and of the Council (May 2003) regarding the promotion of the use of biofuels or other renewable fuels for transport are discussed in the first part of this article. The second part focuses on some new concepts for the future development of technology for biodiesel production, based on the application of non-catalytic transesterification under supercritical conditions or the use of lipases as an alternative catalyst for this reaction.

Nutraceuticals are an ever-expanding market worldwide, facing the unstoppable transition towards a green economy. Developing economically feasible and sustainable alternatives to current raw materials for the extraction of nutraceuticals is, therefore, essential to reach these goals and, at the same time, achieve social and economic competitiveness. This paper intends to propose an economical and environmentally sustainable feedstock for chlorogenic acid (CGA) and inulin, whose current extraction from green coffee and chicory, respectively, is unsustainable. Our approach is based on the multi-criteria decision-making approach (MCDA), supported by the analytical hierarchy process (AHP), ranking the performance of competitor biomasses according to economic, social, and technological criteria. The results of this study highlight cardoon (Cynara cardunculus) as a promising raw material for the extraction of CGA and inulin in virtue of the high concentration, low-input growth regime, and the possibility of being grown on marginal lands. Nevertheless, cardoon biomass availability is currently scarce, extraction methods are underdeveloped, and consequently, the obtained product’s price is higher than the benchmark competitors. Policies and investments favoring sustainable cultivations could stimulate cardoon employment, linking economic advantages and land requalification while limiting phenomena such as desertification and food competition in the Mediterranean basin.

Cement Raw Material

As the selective non-catalytic reduction denitration(SNCR denitration) was used in cement decomposition furnaces under the high concentration cement raw materials and complex flue gas composition , the denitration efficiency is poor and the reducing agent is largely consumed.In order to meet the more stricter requirements of environmental protection, there is an urgent need to improve the denitration efficiency of SNCR and reduce the escape of reducing agentsin order to prevent the unnecessary waste caused by excessive use of reducing agents and secondary atmospheric pollution.Therefore, studying the effect of cement raw materials and O2 concentration on SNCR process is very important. In this paper, the initial concentration of NO and the ammonium to nitrogen ration (CNH3/CNO) was 800ppm and 1.5, respectively. The effects of cement raw material and oxygen concentration on the reaction process of NH3+NO+O2 in the temperature range of 750°C -1100°C were investigated by means of denitration rate, in Situ DRIFTS analysis.The results demonstrate when O2 concentration was 5% and denitration temperature was 950°C, the deNOx rate reached a maximum of 89.64%, which due to O2 promoted NH3 and NO to react with O2 to produce N2 and H2O. However,under the effect of cement raw material, O2 can promote NH3 which was adsorbed on the surface of cement raw material to react with O2 and produce NO and H2O, and the reaction of oxidation of NH3 is dominant, therefore, the denitration reaction is inhibited. .When O2 concentration was 5% and temperature was 850°C, the deNOx rate reached a minimum value of -109.09%. the high concentration cement raw material and flue gas composition reduce the denitration efficiency of cement kiln.

The mountainous areas of the Carpathian basin have provided a wide spectrum of siliceous rocks for prehistoric people. Although the presence of outcrops of a kind of chert, named Buda hornstone was already known by geological and petrographic investigations, the developing Hungarian petroarchaeological research did not pay much attention to this raw material. Its archaeological perspectives have been opened by a discovery made at the Denevér street in western part of Budapest in the 1980s. During the excavations of the flint mine, not much was known about the distribution of this raw material in the archaeological record. Since then the growing amount of archaeological evidences showed that its first significant occurrence in assemblages can be dated to the Late Copper Age Baden culture, and it became more abundant through the Early Bronze age Bell-Beaker culture until the Middle Bronze Age tell cultures. Until now, 15 outcrops of the Buda hornstone have been localised on the surface. Based on thin section examinations taken from two different outcrops, we have made a clear distinction between three variants. In the last few years, archaeological supervision has been conducted during house constructions, suggesting the Buda hornstone occurrence takes the form of a secondary autochthonous type of source. In the framework of our research program, a systematic check of the raw materials is planned in the lithic assemblages of the nearby prehistoric sites, as well as to look for extraction pits or other mining features with the application of geophysical methods and a thorough analysis of the surface morphology

Производство напитков функционального назначения в настоящее время имеет актуальное значение, при этом наиболее перспективными являются напитки, приготовленные на основе натуральных соков с добавлением ингредиентов, выделенных из растительного сырья, в том числе из плодово-ягодного. Помимо органических кислот, аминокислот, витаминов, пектиновых веществ, полифенолов и природных углеводов, эти напитки насыщены также дефицитными микронутриентами, оказывающими позитивное действие на состояние человеческого организма. В статье представлены результаты исследований по разработке рецептур и технологии производства высококачественных функциональных напитков на основе виноградного сока прямого отжима, обладающих улучшенными потребительскими свойствами за счет включения в их состав экстрактов плодово-ягодного сырья - фейхоа, ежевики и черной смородины. Приведена оценка показателей качества и безопасности разработанных напитков и процессуально-технологическая схема их производства. Работа выполнена на базе учебно-научной лаборатории технологии виноделия и продуктов питания из растительного сырья Ставропольского ГАУ. Для определения физико-химических показателей и пищевой ценности сырья, полупродуктов и приготовленных функциональных напитков применяли современные общепринятые методы исследований согласно действующих ГОСТ. Разработка технологии производства напитков на основе виноградного сока с применением плодово-ягодных экстрактов является особенно важной и актуальной задачей в связи с наличием разнообразной и доступной сырьевой базы на Юге России, а также высокой концентрацией в данном регионе плодоперерабатывающих производств, оснащенных современным высокопроизводительным оборудованием. Полученные нами результаты могут способствовать целенаправленному применению разработанных напитков в санаторно-курортном лечении населения для решения проблемы оптимизации питания и повышения пищевого статуса населения России. The production of functional beverages is currently of urgent importance, while the most promising are drinks prepared on the basis of natural juices with the addition of ingredients extracted from vegetable raw materials, including fruit and berry. In addition to organic acids, amino acids, vitamins, pectin substances, polyphenols and natural carbohydrates, these drinks are also saturated with scarce micronutrients that have a positive effect on the state of the human body. The article presents the results of research on the development of recipes and technology for the production of high-quality functional beverages based on direct-pressed grape juice, which have improved consumer properties due to the inclusion of extracts of fruit and berry raw materials - feijoa, blackberry and black currant in their composition. The evaluation of quality and safety indicators of the developed beverages and procedural and technological scheme of their production is given. The work was carried out on the basis of the educational and scientific laboratory of winemaking technology and food products from vegetable raw materials of the Stavropol State Agrarian University. To determine physicochemical parameters and nutritional value of raw materials, intermediates and prepared functional beverages, modern generally accepted research methods were used in accordance with the current GOST. The development of technology for the production of beverages based on grape juice using fruit and berry extracts is a particularly important and urgent task due to the presence of a diverse and affordable raw material base in the South of Russia, as well as a high concentration of fruit processing plants accomplished by modern high-performance equipment in this region. The results obtained by us can contribute to the purposeful use of the developed beverages in sanatorium treatment of the population to solve the problem of optimizing the nutrition and improving the nutritional status of the population of Russia.

In this review, the primary objective was to systematize knowledge about the possibility of improving the health-promoting properties of raw plant products, defined as an increase in the content of bioactive compounds, by using ozone. The greatest attention has been paid to the postharvest treatment of plant raw materials with ozone because of its widespread use. The effect of this treatment on the health-promoting properties depends on the following different factors: type and variety of the fruit or vegetable, form and method of ozone treatment, and dosage of ozone. It seems that ozone applied in the form of ozonated water works more gently than in gaseous form. Relatively high concentration and long contact time used simultaneously might result in increased oxidative stress which leads to the degradation of quality. The majority of the literature demonstrates the degradation of vitamin C and deterioration of color after treatment with ozone. Unfortunately, it is not clear if ozone can be used as an elicitor to improve the quality of the raw material. Most sources prove that the best results in increasing the content of bioactive components can be obtained by applying ozone at a relatively low concentration for a short time immediately after harvest.
