Purpose: Entrepreneurship is a creative skill, offers theoretical and practical information to support individuals’ economic growth in society. The research examines teachers’ expectations and awareness of developing entrepreneurship skills among young learners and defines the connection between play strategy and entrepreneurial skills in early childhood education (ECE).

Methodology: The researcher employed a qualitative research approach. The population of the study comprised of ECE teachers. A purposive sampling technique was used, and twelve ECE teachers were interviewed from six different ECE Centers District East and Central, Karachi.  Thematic analysis was used to analyze the data.

Results: Findings showed that teachers have very limited knowledge or don’t have an understanding of entrepreneurship. According to them, this skill is related to business, and it can be done only through heavy investment. According to teachers’ opinions, it isn’t easy to teach students about entrepreneurship skills in early childhood education. However, they also stated that students are trained in preschools through multiple exercises. The play method is one of the many strategies that improve social behaviors; collaboration, exploration, projects, problem-solving, decision-making, and innovation. Students develop positive social habits through entrepreneurship skills (ES). The research reveals the essential relationship between play strategy and entrepreneurship skills. The study advises that schools equip potential entrepreneurs with early childhood education and play strategy that teachers be qualified to build Entrepreneurship skills among children. 

Applications of the study: The findings of the study promote and activate the curriculum makers, textbook developers, and policymakers to develop entrepreneurship modules that help teachers to enhance their pedagogical skills to promote entrepreneurship skills among young learners through play strategies.    

The Novelty of the Study: This study checked the concepts of entrepreneurship education through play strategies at the ECE level. Besides this, teachers’ perceptions and understandings about entrepreneurship skills at the ECE level were also explored.

Authors: Purkon Arip
Published: March 2021

Purpose of the study: This research aims to analyze the existence of Islamic law formalized into Indonesian law in the Reformation Era from 1999 to 2019 and explore whether it is legally stronger or weaker. Also tries to explore what Islamic law fields are formalized into Indonesian national law.
Methodology: This research is qualitative research that is doctrinal law research with juridical analysis methods. The main source of research data is the law established between 1999-2019. Data is described systematically and objectively, then analyzed using content analysis techniques.
Main Findings: During the Reformation Era 1999-2019, 17 Indonesian national laws contained formal Islamic law. The legal position of Islamic law became stronger in several fields, namely hajj (pilgrimage) and umrah management, management of zakat, implementation of special privileges Aceh Province, endowments (waqf) management, religious courts, state sharia securities, Islamic banking, halal product guarantee, marriage law and the existence of pesantren (Islamic boarding school).
Applications of this study: This study is useful as a model example of a relationship between religion and state. Islamic law can be transformed into state law without changing the state principles. This research also provides a solution to Muslims (they are the majority in Indonesia) that Islamic law can be constituted as national law constitutionally and tolerant of other religious communities.
Novelty/Originality of this study: The object of research is positivization in contemporary Indonesian governance that has been enacted between 1999-2019. In terms of time, this is very representative and updated.
A MIXED-METHOD STUDY TO ENHANCE FOOD SECURITY BY REDUCING POST-HARVEST WHEAT LOSSES IN PUNJAB, PAKISTAN
Authors: Manzoor Adeela , Ahmad Maan Ashfaq , Ahmad Khan Izhar , Shahbaz Babar
Published: March 2021

Purpose of the study: The major purpose of this study was to enhance food security by reducing wheat losses.

Methodology: A mixed-method research was used for data collection. Six focus group discussions and six key-informant interviews were conducted to cover qualitative aspects while 400 face-to-face interviews were conducted. The study was conducted in three randomly selected districts of Punjab. Six tehsils, two from each district were further selected randomly. From each selected tehsils, four hundred farming households were selected through a proportionate sampling technique, and data were collected through an interview schedule. : For the qualitative aspect thematic analysis was used to analyze data. The quantitative data were analyzed through the statistical package for social sciences (SPSS)

Main Findings: The result of the present study shows that majority of respondents having old age were doing wheat post-harvest activities and they have only a primary level of education. The farmers who have access to extension services had less level of losses rather than others.   Qualitative results show that the farmers who are trained with techniques to manage post-harvest activities have fewer losses as compare to the farmers who are not trained.

Applications of this study: It is concluded that hurdles regarding canal water, marketing, transportation, and practices of traditional methods for wheat storage lead to post-harvest losses as well. It is a sheer need of time to train the people (involved in postharvest management activities) to reduce the postharvest losses according to their needs.
Depression and Cardiovascular Diseases
Authors: Agarwal Shashi
Published: March 2021

Cardiovascular diseases (CVD) are the leading cause of global morbidity and mortality. Besides imparting enormous human suffering and enhancing premature mortality, they also inflict huge direct and indirect financial costs on the worldwide society. With the easier availability of affordable therapeutics globally, and the relatively paucity of newer innovations, modifiable risk factors are gaining greater importance in the management of this cardiovascular epidemic. Depression is a modifiable risk factor. It is consistently and strongly associated with a higher risk of CVD incidence and mortality. CVD on the other hand, often induces the development of depression. This paper reviews the effects of depression on cardiovascular diseases.
Physical and economic aspects of the earliest Septuagint papyri
Authors: van der Louw Theo A.W. , Hartog Pieter B.
Published: March 2021

The physical features of the earliest LXX papyri provide clues to their provenance, ownership and intended functions. Additionally, we can approximate the production costs of these rolls on the basis of the dimensions of these papyri and papyrus prices and copying tariffs in documentary papyri. Early LXX manuscripts were priced from 27 to 103 drachmas in Egypt, depending on the length of the book and the spaciousness of the layout. Freight rates probably averaged around 30 per cent for transport from Alexandria to Jerusalem in the first century CE, making papyrus more expensive in Palestine. The incorporation of Egypt and Palestine into the Roman Empire reduced freight rates, so that papyrus became available to new circles in Palestine. For economic reasons, it is likely that Greek biblical papyri were copied in Palestine. A comparison with consumption baskets shows that only the elite and the ‘retainer class’ could afford these manuscripts.

The Hebrew epithalamium in late antiquity: new evidence  from the Cairo Genizah and beyond
Authors: Granat Yehoshua
Published: March 2021

Several anonymous Hebrew epithalamia (wedding poems), preserved in manuscripts from the Cairo Genizah, can be dated, in view of their specific literary characteristics, to Byzantine (and early Muslim) Eretz Israel (Palestine): noteworthy evidence of the flourishing of non-liturgical Hebrew poetry in late antiquity. The article demonstrates and analyses these poems’ affinities to Jewish Palestinian Aramaic epithalamia, in terms of subject matter and rhetoric, as well as their resemblance to classical Hebrew piyyut, in terms of language and style. They are also examined against the background of the performance of Hebrew wedding songs as reflected in Talmudic sources, and it is suggested that the influence of such non-liturgical epithalamia can be detected in the earliest known piyyut composition which marks the occasion of marriage, a Qedushta by El’azar birabi Qillir (Kalir). Some comparable characteristics of these non-liturgical Hebrew wedding poems and the epithalamium genre in Greco-Roman late antiquity are also considered. The article includes critical editions and English translations of two Hebrew epithalamia from the Cairo Genizah.
R. Nachman of Tshe’erin’s Kuntres Inyan ha-Hishtahut
Authors: Mandelbaum Alexandra
Published: March 2021

The focus of this article is the
Kuntres ‘Inyan ha-Hishtahut al Kivrei Zaddikim
(A Pamphlet about the Matter of Prostration on the Graves of the Righteous) by R. Nachman Goldstein of Tshe’erin (1825–1894). My goal is to show how this short pamphlet contributed to the formation and development of one of the central traditions of Bratslav Hasidim: the annual pilgrimage to the grave of R. Nachman of Bratslav in Uman on Rosh HaShanah, the Jewish New Year. This core Bratslav practice keeps Bratslav Hasidism alive and vibrant and serves to expand its ranks. The
Kuntres
advances the idea of the
kibbutz hakadosh
(holy gathering) as an essential Bratslav ritual. Later, when historical forces made it impossible to travel to Uman, Bratslav Hasidim in Poland transformed Uman into an object of spiritual longing. This article tells the story of the connection between the pamphlet, theology and history in Bratslav Hasidism.
Witch-hunt or women’s oppression? The secularization and re-enchantment of the witches of Ashkelon tale by contemporary spiritualities’ leaders
Authors: Ruah-Midbar Shapiro Marianna
Published: March 2021

This study analyses the cosmology and theology being shaped by alternative spiritualities regarding the link between witchcraft and women. It raises issues of secularization and re-enchantment, religious/spiritual identities and feminism. The case study is the Israeli alternative spiritualities’ leaders re-narration of a tale from rabbinic literature about the Ashkelon witch-hunt led by Rabbi Shim’on ben Shatach. This tale has been reshaped in different ways by spokespersons who represent various spiritual Jewish-Israeli paths. All alternative spiritual texts analysed here demonstrate their authors’ identification with the rejected anti-heroines, the Ashkelonian witches. Some appropriate Judaism, whilst others criticize it; some write from within it, others from without. The alternative spiritual texts reflect different cosmological views contending with issues of secularization versus re-enchantment, as well as various theologies or thealogies, and different religious feminist tones.

Drilling deep holes or drilling to provide access to thermal waters places increasingly high demands on the properties of the drilling muds. Due to the very high temperature, it may be difficult to maintain the appropriate rheology of the drilling fluid during drilling, especially when an inflow of highly mineralized brines occurs. High temperatures significantly reduce the effectiveness of most of the polymeric agents currently used in the drilling muds technology, in extreme cases causing complete and irreversible damage to their structure. Polymers with ether bonds, which include starches and cellulose, are the most vulnerable. Based on the literature data, it can be concluded that the disadvantages of these polymers can be effectively compensated by the addition of synthetic polymers, e.g. sulfonated polymers. Another direction in improving the thermal resistance of drilling muds indicated in the literature is the use of carbon nanoparticles: graphene flakes and nanotubes. The article presents an analysis of the possibilities of improving thermal stability of drilling muds by using chemical agents that allow to maintain appropriate rheological and structural parameters and filtration at temperatures up to 130°C. During the tests, three types of chemicals were added to the polymer-potassium drilling mud at different concentrations. The impact of these modifications on technological parameters of the drilling mud was tested. Then, samples modified by the addition of selected agents were exposed to the temperature of 130°C for a period of 24 hours. After this time, the samples were cooled to 20°C, then their technological parameters were measured and compared with the results obtained before aging at high temperature, and based on the obtained results, the effectiveness of individual agents was assessed. Among the agents tested to protect drilling mud against the adverse effects of high temperature, the most beneficial effect was shown by potassium formate in combination with PoliAMPS.

Invert muds are the most commonly used oil-based drilling muds. The oil to water phase ratio in invert drilling muds ranges from 65/35 up to 90/10, with the most common ones ranging from 70/30 to 80/20. At these oil to water phase ratios, the drilling mud is characterized with high stability and appropriate rheological and structural parameters allowing to adjust drilling mud density in a wide range. One of the disadvantages of invert muds is their cost (due to oil content) and environmental problems associated with waste and management of oily drill cuttings. Taking into account the properties of oil-based muds, the article presents laboratory tests aimed at developing the composition of an invert mud with a limited oil phase content and high internal phase ratio (HIPR). Drilling muds with an o/w ratio less or equal to 50/50 vary from conventional inversion muds in terms of their composition and properties. Due to the higher concentration of the dispersed inner phase, muds have reduced stability and high rheological and structural parameters. Maintaining the appropriate rheological and structural parameters of the drilling mud and its high stability is possible only through the use of appropriate chemicals adapted to the emulsion system with a specific oil to water phase ratio. In the drilling muds of this type it is also possible, due to the higher concentration of the internal phase, to partially adjust the density of the mud with the water phase, such as salt solutions, thus limiting the solids content (weighting agents) in the mud. The developed mud system should be more economical, have a reduced toxicity, while maintaining the operational advantages of invert mud. These types of muds can be used during the drilling of reactive shale formations, salt layers, gypsum and anhydrite layers, as well as for drilling productive horizons and for reconstruction works carried out in oil and gas wells.
Comparative study of combustion and emissions of diesel engine fuelled with FAME and HVO

Published: March 2021

This study investigates combustion and emission characteristics of a contemporary single-cylinder compression ignition engine fuelled with diesel, fatty acid methyl esters (FAME) and hydrotreated vegetable oil (HVO). These two drop-in fuels have an increasing share in automotive supply chains, yet have substantially different physical and auto-ignition properties. HVO has a lower viscosity and higher cetane number, and FAME has contrary characteristics. These parameters heavily affect mixture formation and the following combustion process, causing that the engine pre-optimized to one fuel option can provide deteriorated performance and excess emissions if another sustainable option is applied. To investigate the scale of this problem, injection pressure sweeps were performed around the stock, low NOX and low PM engine calibration utilizing split fuel injection. The results showed that FAME and HVO prefer lower injection pressures than diesel fuel, with the benefits of simultaneous reduction of all emission indicators compared to DF. Additionally, reduction of injection pressure from 80 MPa to 60 MPa for biodiesels at low engine load resulted in improved brake thermal efficiency by 1 percentage point, due to reduced parasitic losses in the common rail system.

Wood density is an important physical property that can be easily measured and is closely related to many other wood properties. Furthermore, wood density is a good indicator of the usability and applicability of wood in the wood processing, construction and energy industries. Because it is strongly dependent on moisture content and porosity, there are various definitions of wood density in the literature, among which the density measured on the basis of dry matter and volume is the most commonly used. The aim of this paper is to present different methods for wood density determination and the importance of collecting such data for the development of the forest-based bioeconomy. In practice, there are several direct and indirect methods of density measurement; in addition to the most basic volumetric approach, the density of wood can be measured by penetrometer, resistograph, high frequency densitometry, X-rays, near infrared spectroscopy and microwaves. Wood will continue to grow in importance, as it is one of the key raw materials for the transition to a sustainable bioeconomy. The accurate and timely determination of wood density allows for the appropriate distribution and direction of flows of this raw material between individual conventional and new sectors (areas of use) and thus its more efficient and sustainable use.
Reconstruction of brown bear population dynamics in Slovenia in the period 1998-2019: a new approach combining genetics and long-term mortality data
Authors: Jerina Klemen , Ordiz Andrés
Published: March 2021

Reliable data and methods for assessing changes in wildlife population size over time are necessary for management and conservation. For most species, assessing abundance is an expensive and labor-intensive task that is not affordable on a frequent basis. We present a novel approach to reconstructing brown bear population dynamics in Slovenia in the period 1998-2019, based on the combination of two CMR non-invasive genetic estimates (in 2007 and 2015) and long-term mortality records, to show how the latter can help the study of population dynamics in combination with point-in-time estimates. The spring (i.e. including newborn cubs) population size estimate was 383 (CI: 336-432) bears in 1998 and 971 (CI: 825-1161) bears in 2019. In this period, the average annual population growth rate was 4.5 %. The predicted population size differed by just 7 % from the non-invasive genetic size estimate after eight years, suggesting that the method is reliable. It can predict the evolution of the population size under different management scenarios and provide information on key parameters, e.g. background mortality and the sex- and age-structure of the population. Our approach can be used for several other wildlife species, but it requires reliable mortality data over time.

Generally applicable and professionally applied criteria for acceptable soil damage after forest operations are a prerequisite for efficient forest soil protection and objective control of the quality of forest operations. This research took the form of a survey conducted among forestry experts to examine the acceptability of the criteria proposed by Poje et al. (2019) on the basis of previous studies. The survey was conducted on the 35th Forestry Study Days Conference and involved 62 respondents from different institutions. The results of the survey showed that the harmonised criteria are stricter than the proposed criteria and that the assessments by individual indicators within the criteria vary between stakeholders. According to the proposed harmonised criteria, a density of 192 m/ha with skid trails and an additional 193 m/ha with harvester trails is allowed. The maximum rut depth in skid and harvester trails shall not exceed 30 cm and 20 cm, respectively. The maximum rut depth on 90% of the length of all harvester trails at the logging location shall not exceed 10 cm. Based on the results of other studies, the proposal for harmonised criteria also appears to be reasonable and appropriate from a technological, economic and environmental point of view. Before the harmonised criteria are introduced in practice, a method for assessing soil damage needs to be developed, in addition to on-site verification of the respective criteria and their possible reorientation.

Published: March 2021

Length of stay (LOS) or length of stay is the main indicator in improving health services, which is expected to continue to increase along with population growth. The population of Indonesia is included in the largest category in the world. This was followed by an increase in the number of inpatient and emergency unit visits which had a high burden of care costs. This study aims to provide a solution by predicting LOS using Neural Network (NN). Predictions can be used as a consideration in improving effective and efficient health services. To improve the performance of the NN algorithm, we implement parameter optimization using the Grid Search to find the combination of the number of epochs, learning rate and momentum that can produce the best accuracy value. The results showed that NN could predict LOS with an accuracy rate of 89.22% when using the default parameter. Meanwhile, by performing parameter optimization using the Grid Search to find the ideal combination of parameters for learning rate, momentum and epoch, the accuracy rate is increased to 92.20%.

The possibility of increasing the shelf life of dried apricot with application of uv radiation
Authors: Kolokolova A. Y. , Iliukhina N. V. , Maslennikova M. A.
Published: March 2021

The use of physical methods of processing, in particular ultraviolet radiation, is used in the food industry for the purpose of disinfection of raw materials, semi-finished products and finished products, which increases the storage time. The process of processing food products with ultraviolet light quickly proved itself. This method does not change the taste of the product, increases the shelf life and sales, and is a non-thermal method of deactivating pathogens. The wide use of the bactericidal effect of UV rays for food products is limited by their low penetration capacity, so the UV spectrum can be used mainly for sur-face sterilization, provided that the deep layers of the material do not contain microflora. The effectiveness of UV radiation depends on the following factors: the source and the UV dose; the sensitivity of microorganisms to UV light; the composition and physical properties of the product. Object of research: model media containing native microflora of dried fruit raw materials "dried Apri-cots". The research was carried out using model media simulating the proper-ties of the raw material surface, excluding its protective mechanisms and allow-ing to reveal the true dynamics of inhibition of native microflora. Native micro-flora of dried fruits implies a set of microorganisms. Literature sources have shown the possibility of the presence of such types of microorganisms as E. coli, Salmonella, Candida, Pseudomonas, spore forms of microorganisms on the surface of raw materials. During the experiment it was determined that the treatment duration of 5 min reduced the initial contamination of 2 order pro-cessing in 10 minutes – 2.6 the order in 15 minutes – 2.7 order and 20 minutes for 3 orders of magnitude.

The article discusses the development of a technology for obtaining a functional food product using meat and vegetable raw materials. The aim of the study is to develop a combined food product for therapeutic, prophylactic and functional purposes. An improved recipe for rabbit meat paste with the addition of plant components is proposed. The developed technology was used to produce meat pastes based on a balanced ratio of the main food ingredients, providing improved digestibility, assimilability, biological value while achieving the best consistency. Rabbit meat is used as a meat component. Chickpea flour, onions, garlic, sesame oil, carrots, table salt, cloves, ground black pepper, paprika, broth and water were used as plant components. The broth obtained after boiling the rabbit is used. Quality assessment by organoleptic and physicochemical parameters was carried out according to generally accepted methods. This recipe made it possible to obtain a food product of a functional orientation, balanced in chemical composition, containing vegetable and animal proteins, fats, a sufficient amount of carbohydrates, vitamins A, C, E and such biologically significant elements as iron, calcium, potassium, sodium, magnesium, phosphorus, manganese, zinc, iodine, etc., with high organoleptic characteristics. The mass fraction of protein was at least 16.5%, fat - 17.2%, carbohydrates - 1.5%. The calorie content of 100 g of finished paste was 226 Kcal.

Published: March 2021

In the course of the work, the influence of the amount of crushed green buckwheat on the organoleptic characteristics of the product was studied, taking into account the degree of grinding. 1, 2, 3, 4 and 5% fraction of green buckwheat were added to the curd base. On the first day of storage, the chemical composition of the samples was analyzed. The results show that the percentage of fat in the image samples was increased compared to the control - from 1.77 to 1.88. The content of the proportion of protein in the control sample was 3.86%. An increase in the size of protein compression was noted in all samples. The ash content in the samples showed a tendency to increase in comparison with the control and varied in the range from 0.72 to 0.90%. The moisture content in the control sample was 86.67%, in the remaining samples - from 83.96 to 85.92%. In the course of the analysis, the change in the samples of the experiment with green buckwheat during storage was studied, taking into account the organoleptic indicators. Analysis of the data obtained shows that initially the pH changes little up to 15 days of storage, then gradually decreases. Initial CFU values were 6.00 ? 107 for sample (2%), 7.50 ? 107, 5.00 ? 107, and 6.50 ? 107 for sample (3%), sample (1%), and sample 2 (3% ). ) respectively. B shows a trend towards a tracked decrease before the end of the shelf life. The guaranteed shelf life of the green buckwheat curd product is 14 days at a temperature of 4 ± 2?С, which is experimentally substantiated. This storage time is a satisfactory indicator. The product is promising for sale to consumers.

Street food or street food is the format of the food industry enterprises. At such enterprises, the cooking process is focused on the prompt production of products and dishes from semi-finished products and their implementation in street kiosks, pavilions, on mobile counters and carts. The so-called "Hong Kong waffles" are popular as a street food product. One of the effective ways to increase the nutritional value and reduce the energy value of flour confectionery products, which are expedient from a physiological and technological standpoint, can be the use of stevioside sweetener, sea buckthorn oil and Hi-Maize resistant starch as sources of micronutrients (biologically active substances): vitamins, mineral elements and other compounds. Tasting analysis showed that the highest organoleptic properties, as close as possible to the control sample, were possessed by test sample 2 with the addition of 100% stevioside, 100% sea buckthorn oil and 15% of resistant Hi-Maize starch by weight of flour. Samples 4 and 5, the formulation of which included 15% of dried and crushed sea buckthorn cake, scored the least points in the organoleptic assessment, since they have a sea buckthorn aftertaste and a drier and denser crumb compared to other samples. Samples 1 and 3 received a low rating. Sample 1 had a faint aftertaste, probably due to the presence of tri-terpene saponin-licurazide in stevia, which contains a bitter licorice aftertaste. The use of stevioside sweetener, sea buckthorn oil and resistant starch Hi-Maize will not only reduce the calorie content of food products, intensify production processes, but also significantly expand the range of flour confectionery products.

One of the directions of development of innovative confectionery products is the creation of products using raw materials with critical significant substances to improve public health. The creation of confectionery semi-finished products based on fresh vegetables and fruits with a minimum temperature effect to ensure the preservation of native micronutrients are an urgent task of enriching confectionery. Cavitation is a method of physical influence in the production of confectionery and semi-finished products, which helps to increase the preservation of vitamins by reducing the duration of temperature exposure and achieving the desired properties of the semi-finished product. The aim of the study was to study the influence of cavitation effects on the structural, mechanical and physicochemical indicators of semi-finished products from fresh vegetables for the production of confectionery. Model samples of a semi-finished product are made from carrots using acoustic exposure with various durations (from 0 to 6 minutes) using invert syrup obtained by cavitation treatment. The obtained samples were compared with a control sample of a semi-finished product from carrots with the addition of invert syrup without cavitation treatment. The use of cavitation effects at the stage of obtaining invert syrup and processing carrot mass made it possible to increase the strength of the confectionery semi-finished product made on the basis of carrot raw materials by 19% to 640 g / cm3. The initial water activity of the control sample was 0.852, which indicates a high risk of microbiological changes during storage. Cavitation treatment contributed to a minimal change in the water activity of the semi-finished carrot-based product during storage. With an increase in the duration of the cavitation treatment of the carrot mass, the amount of reducing substances increased in the samples of carrot semi-finished product, in the control sample - 6.3%, in the sample from 4 and 6 minutes. cavitation treatment - 44.1% and 47.3%, respectively. A study of a semi-finished product by gas chromatography with a mass spectrometric detector revealed a significant effect of cavitation effects on the chemical composition. A decrease in the content of fumaric acid esters in the sample with the duration of cavitation effects of 4 and 6 minutes was revealed from 2.91% to 1.72% and 1.2%, respectively, compared with the control sample. At the same time, the organoleptic characteristics of the taste and smell of the semi-finished product have improved.

The aim of the study was to determine the type of solvent that allows the most complete extraction of antioxidant substances from white, black and green tea (Camellia sinensis). The objects of the study were extracts of three types of tea obtained using various solvents: water, a mixture of water-ethanol (75% vol./25% vol.), A mixture of water-ethanol (50% vol./50% vol.), A mixture of water -ethanol (25% vol./75% vol.) and ethanol (96%). In extracts of white, black and green tea, the total content of phenolic substances, flavonoids, antiradical activity by the DPPH method, and the restoring force by the FRAP method were determined. The maximum values of the total content of phenolic substances were found in the extract of white tea based on ethanol and a water-ethanol solvent system (50/50), black tea when extracted with water, green tea with a water-ethanol solvent ratio (50/50). High values of the total content of flavonoids were established for white tea extract based on a water-ethanol solvent system (50/50), black tea when extracted with water, green tea, when using ethanol as a solvent. Low antiradical activity was found in white tea extract based on a water-ethanol solvent system (50/50), in ethanol-based black tea, and green tea showed low values when extracted with water. The highest index of restorative power was found in white tea extract based on a water-ethanol solvent system (25/75), in black and green tea when extracted with water. Thus, as a result of the study of extracts of white, black and green tea, it was found that when the white tea is extracted with a water-ethanol (50/50) solvent system, the largest amount of antioxidant substances is extracted. The maximum amount of antioxidants from black and green tea is extracted using water as a solvent.

The description of the existing method for producing invert syrup in stages in a large volume under the conditions of using one type of energy flow is given. The purpose of this work is to develop the principles of transition from macrostatic equilibrium to the development of each microstatic volume of liquid dispersed systems in the process of their production in a non-equilibrium state created by the combination of two types of cavitation effects: hydrodynamic and acoustic effects. The properties of dispersed systems are described and the object of research is invert syrup with the amount of dry 80% and reducing 79-80% substances. Invert syrup with 100% inversion of sucrose to glucose and fructose is widely used in the production of flour confectionery and a number of pastille and marmalade products. The principles of formation of aggregates from sucrose molecules at the stage of sugar dissolution, the formation of voids and the nucleation of gas phase bubbles are established. The conditions for creating a non-equilibrium state of syrup under the conditions of using two types of energy flows, by combining hydrodynamic and acoustic cavitation, are considered. The character of the transformation of the state of bubbles under conditions of changing the flow geometry of gas-liquid systems and the excitation of sound vibrations in them is shown. The mechanism of structure formation of a gas-liquid system under the influence of acoustic vibrations on the structure is described. The character of transformation of highly concentrated gas-liquid systems after the collapse of gas phase bubbles is shown, which was the determining factor in the formation of new types of materials. The practical output of this work was the creation of invert syrup with 100% fructose and glucose content in dry substances. Preparation of an emulsion for flour confectionery products and marmalade based on fresh fruits and vegetables. The effectiveness of combining two types of cavitation exposure opens up the prospect of creating new types of confectionery products with fundamentally new properties, while preserving native vitamins and nutrients.

There has been a significant increase in the oat (Avena sativa. L) consumption recently due to the new scientific data on dietary properties of oats, high content of polyphenols, especially Avenanthramides, and some flavonoids with an antioxidant effect. However, the thick layer of the cell wall in the hypoaleurone area and the uneven distribution of nutrients over the kernel determine the need to find effective technological solutions for their use in food production. The use of whole grain and its sprouting could be one of the possible solutions. Sprouting breaks difficult to digest grain complexes, thus making nutrients available for plant development and easier for human body intake. In the framework of this study, we propose to activate the process of grain sprouting by ultrasonic treatment of water used for preliminary grain soaking. The research results revealed that the proposed method accelerates accumulating of polyphenolic substances, phenolic acids and total antioxidant capacity. The mass fraction of polyphenolic substances in Avena sativa L. samples preliminarily aged in water treated with ultrasound (315W) for 2 minutes was 2.811 mg CAE/g, which is 4.64 times more than the mass fraction of the reference non-sprouted sample. Accumulation of phenolic acids at different treatment modes was intensified by 30.5% and more compared to the non-sprouted grain. Mathematical processing of the total antioxidant capacity (DPPH) results established a reasonable mode of ultrasonic water treatment used for grain soaking - 400 W for 2 minutes, the total antioxidant capacity will be 2.254 mg TEAC / g. Thus, the ultrasonic effect can be recommended as an intensifier in grain sprouting.
