The Vámoscsalád-Kavicsbánya Site (Vas County)

The archaeological artefacts of the Vámoscsalád-Kavicsbánya site were discovered, collected and preserved by István Marton and his brother, András Marton, mineral collectors from Mesterháza, in about 2015. The slight elevation on a terrace of the Répce River was mined for the M86 highway in 2012–2013. Apart from knapped stone tools, the main subject of our paper, several polished serpentinite and greenschist tools have been recovered from the site, which could be in use between the Neolithic and the end of the Bronze Age. Only a few potsherds indicated a settlement of the Transdanubian Linear Pottery culture (TLPC). Of the Copper Age, Lengyel III and Baden pottery fragments and a clay spatula are worth mentioning. Almost the entire Bronze Age is represented, the most exciting find being a rim fragment of a bowl, decorated with an encrusted geometric pattern on both sides, of the Somogyvár–Vinkovci culture. Given the presumed mixed character of the knapped stone record of the Vámoscsalád-Kavicsbánya site (as the finds were not recovered from a closed stratigraphic context), we looked for possible cultural analogies and relationships, primarily those corresponding to the system of raw material–technology–typology. Although the pottery fragments of the TLPC recovered from the site are few and uncharacteristic, and the recovered finds may represent more than one phase, the knapped stone assemblage most likely represents the industry of the Middle Neolithic cultural unit, as suggested by raw material composition, technological features, type distribution and characteristics of the retouched tools. It is perhaps even possible that we are dealing with relatively old, if not the oldest TLP finds ever unearthed in the county.

Using of nontraditional raw materials in beer production

Given the highly competitive environment of brewing industry today, businesses need to constantly develop new products of high quality and nutritional value that meet consumer and sanitary requirements. Therefore, the production of beer-based mixed beverages using nontraditional raw plant materials is gaining popularity. It is quite possible to produce these types of beverages at brewing facilities of Almaty and the Almaty region since it presents a favorable climate to develop agricultural businesses producing fruits and berries and has a large potential for using wild crops. Using of these plants will keep the enterprise economically viable by expanding the assortment of products and increasing the share of low-alcohol beverages in total production. In this study, the purpose is to select the optimum method for the production of special beer based on apple and grape juice. The choice of these particular types of raw plant materials was due to their wide availability and suitability for juice processing. The methods of introducing juice into young beer after the post-fermentation stage, as well as the introduction of fermented juice into young beer, were applied in the production of a mixed beverage. The organoleptic, physicochemical properties of the finished beer made using two methods have been studied. As a result, the optimal beer to juice ratio of 70:30 was selected according to the first method. This method resulted in the most balanced combination in terms of organoleptic characteristics, but colloidal instability was observed. For the second method of special beer production, the Oettinger Pils yeast race was used for fermentation of the juice base that was introduced into young beer after the post-fermentation stage. The resulting beverage at the 50:50 ratio of beer to juice was highly stable and had the highest organoleptic and physicochemical qualities.

Emissions of Formamide and Ammonia from Foam Mats: Online Measurement Based on Dopant-Assisted Photoionization TOFMS and Assessment of Their Exposure for Children

Formamide has been classified as a Class 1B reproductive toxicant to children by the European Union (EU) Chemicals Agency. Foam mats are a potential source of formamide and ammonia. Online dopant-assisted atmospheric pressure photoionization time-of-flight mass spectrometry (DA-APPI-TOFMS) coupled with a Teflon environmental chamber was developed to assess the exposure risk of formamide and ammonia from foam mats to children. High levels of formamide (average 3363.72 mg/m3) and ammonia (average 1586.78 mg/m3) emissions were measured from 21 foam mats with three different raw material types: ethylene-vinyl acetate (EVA: n = 7), polyethylene (PE: n = 7), and cross-linked polyethylene (XPE: n = 7). The 28 day emission testing for the selected PE mat showed that the emissions of formamide were 2 orders of magnitude higher than the EU emission limit of 20 μg/m3, and formamide may be a permanent indoor contaminant for foam mat products during their life cycle. The exposure assessment of children aged 0.5-6 years showed that the exposure dose was approximately hundreds of mg/kg-day, and the age group of 0.5-2 years was subject to much higher dermal exposures than others. Thus, this study provided key relevant information for further studies on assessing children's exposure to indoor air pollution from foam mats.

Изучение закономерностей накопления наиболее опасных экотоксикантов в дикорастущем лекарственном растительном сырье различных экотопов Воронежской области

Voronezh region is one of the most important areas of agriculture and crop production. The purpose of the study was to study the patterns of accumulation of the most dangerous heavy metals in wild medicinal plant raw materials of various ecotopes of the Voronezh region. The accumulation of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic was studied, using an example of 10 types of medicinal plant raw materials, which were produced in 51 ecotopes of the Voronezh region. When analyzing the average values of the accumulation coefficients of heavy metals and arsenic by all studied types of medicinal plant raw materials, it is possible to build up a series of decreases in the total average accumulation efficiency of the determined elements for these plants, which is as follows: zinc> copper > cadmium > cobalt > nickel > arsenic > chromium > lead > mercury. When analyzing the values of accumulation coefficients, rows of decreasing efficiency of accumulation of elements in all types of medicinal plant raw materials studied are constructed. A detailed analysis of the characteristics of the accumulation of heavy metals and arsenic from soils in medicinal plant raw materials showed the presence of aclose positive relationship between concentrations in soil and plants for most of the determined elements, which indicates the predominant contamination of plant raw materials through the soil.

Geometric Morphometrics and Machine Learning Models Applied to the Study of Late Iron Age Cut Marks from Central Spain

Recently the incorporation of artificial intelligence has allowed the development of valuable methodological advances in taphonomy. Some studies have achieved great precision in identifying the carnivore that produced tooth marks. Additionally, other works focused on human activity have managed to specify what type of tool or raw material was used in the filleting processes identified at the sites. Through the use of geometric morphometrics and machine learning techniques, the present study intends to analyze the cut marks of the Ulaca oppidum (Solosancho, Ávila, Spain) in order to identify the type of tools used during carcass modification. Although the Ulaca oppidum is an Iron Age site, the results suggest that most of the cut marks were produced with flint tools.

Research of demand and consumer preferences of processed fruit and berry raw materials and products based on them

Scientific research is aimed at studying the demand and consumer preferences in choosing the type of fresh raw materials, processed fruit and berry products and products based on them. In order to conduct a consumer assessment, it is necessary to investigate the preferences of consumers and identify by what criteria they prefer to buy and consume processed fruit and berry products. A sociological survey was conducted in order to identify and then form the consumer properties of processed berries and stone fruits. The analysis of the survey showed that the most popular berries are: strawberries, black currants, cherries, cranberries, raspberries, blueberries and blackberries. The results showed that the largest part of respondents prefer to buy frozen and dried berries in the spring and winter period in order to make up for vitamin deficiency, the rest do not buy these products, I motivate that fresh berries are always better than processed ones and cannot make up for all the necessary micronutrients. It was found that 21% of consumers prefer frozen berries and fruits to be used for compotes, 18% – fruit and berry fillings, 16% – jelly, 15% – fruit drinks, 9% – jelly-like products and only 4% in thawed form. Catering establishments use frozen berries and stone fruits mainly for the preparation of compotes, fruit drinks, smoothies (38%), as well as for sauces, culinary, sweet and dessert dishes. Confectionery enterprises are used for the preparation of berry fillings. Consumers prefer dried fruit and berry products in the form of snacks for snacking, making drinks, as a component in various confectionery products and in jelly, and desserts.

Investigation of the biochemical activity of starter compositions enriched with propionic acid bacteria on various raw materials

Currently, there is a need to develop an assortment of low-lactose or lactose-free dairy products and plant-based products due to an increase in the number of consumers with lactase deficiency, allergic to cow's milk components, cholesterol problems, etc. For the development of plant and lactose-free bioproducts, it is possible to use various starter cultures enriched with probiotics. Various starter cultures were used in the work, propionic acid bacteria were used as a probiotic. The objects were lactose-free milk and vegetable bases: rice milk, oat milk and coconut milk; the control was selected milk. A comparative analysis of the fermentation process of various compositions of starter cultures enriched with propionic acid bacteria on various raw materials was carried out. The duration of fermentation of vegetable raw materials is 8-10 hours, the acid-forming activity of combined starter cultures is quite high. The number of viable cells of lactic acid and propionic acid bacteria in the obtained bioproducts has a high value and amounts to 107-108 K.O.E. /cm3. This confirms that the nutrient medium for the cultivation of selected starter compositions is favorable, the microflora of the starter composition develops harmoniously. Lactic acid microorganisms and propionic acid bacteria make it possible to obtain fermented biological products with a variety of taste characteristics inherent in a certain type of raw material. According to the results of the research, the developed starter compositions meet the requirements for starter cultures, have valuable technological properties that allow expanding the range of plant and lactose-free biological products.

EXTRACTION OF POLYPHENOLIC COMPOUNDS FROM THE JUGLANS REGIA L. PELLICLES OF USING ULTRASOUND

The attention of Russian and foreign scientists is focused on obtaining secondary plant metabolites, including phenolic compounds, due to their pharmacological activity. The Juglans regia L. pellicles are a promising raw source for the production of alkaloids, naphthoquinones (juglone), tannins and organic acids. In modern practice of obtaining biologically active substances from plant raw materials, intensive extraction methods are of particular interest. In this extraction method ultrasonic treatment is used to increase the yield and intensify the process of extracting biologically significant substances. Technological parameters of ultrasonic treatment must be selected individually for each type of plant raw material. The aim of the work was to study the effect of ultrasonic treatment on the yield of polyphenolic substances during extraction from the pellicles of breeding varieties Juglans regia L. It was found that the content of tannins in the pellicle biomass of the studied varieties Juglans regia L. varies from 5.2 to 7.3 g/100 g, phenolic compounds – from 17 to 18.2 mg/100 g. The highest content of these compounds was recorded in the pellicle biomass of the Valentina's Gift variety. It was found that ultrasonic treatment with a power of 200 W for 10 min contributes to the highest yield of polyphenolic substances in the extract from the pellicle biomass of the Valentina's Gift variety. However, the spectral profiles of hydroalcoholic extracts indicate the opposite: 200 W ultrasound reduces the intensity of the extraction of polyphenolic compounds.

Degradation of Chinese handmade papers with different fiber raw materials on molecular and supramolecular structures

As the carriers of paper-based cultural relics, ancient handmade papers have greatly promoted the development of human culture, knowledge and civilization. Chinese papermakers wisely selected a broad variety of plants to make papers with better properties and longer lifetime. However, the correlation between the types of fiber raw materials and the durability of handmade papers is still unclear. Herein, six handmade papers classified as bark paper, bamboo paper and grass paper were selected to study their aging behavior and degradation mechanism. Optical microscope and fiber quality analyzer were used to characterize the fiber morphology and length distribution of papers. The degradation kinetics of six handmade papers were systematically studied under accelerated aging condition. On molecular scale, the degradation rate, variation of pH, oxidation degree, chromaticity, and content of reducing carbonyl groups were discussed for bark, bamboo and grass papers. On supramolecular scale, the crystallinity, energy and distance of hydrogen bonds for paper cellulose were quantitatively calculated. For six handmade papers, most of the degradation occurs in the amorphous region of cellulose, leading to the cleavage of glycosidic bonds, the generation of oxidized groups, and the variation of H-bonds arrangement. Owing to the specific molecular and supramolecular structures of cellulose in bast fiber, bark papers have longer lifetime and better durability than bamboo and grass papers. The results of this work will improve the understanding of paper degradation mechanism at microscopic multiscale structures, and provide the scientific foundation for the preparation of handmade papers with better durability.

Operational Issues of Using Replacement Fuels to Power Internal Combustion Engines

The classification of engine fuels was systematised in the present study. The basic evaluation criterion included the type of raw material used for the production of motor fuel and the prevalence of its usage. There was a reason for the purposefulness of searching for new kinds of engine fuels not only for the sake of environmental protection but also for the rational use of natural resources. The concept of substitute fuels was methodically presented. The criteria for the qualification of substitute fuels for internal combustion engines were systematised. Using the example of fuels produced from bio-oils, tests were carried out to assess the prospects of considering bio-oil fuels as substitute ones for self-ignition engines. Accordingly, an analysis was, inter alia, conducted on the fuel combustion process in the cylinder of a test self-ignition engine. Based on the results obtained, the thesis was formulated that rapeseed methyl ester (RME) fuel can be considered a substitute fuel for modern self-ignition engines. There are no significant differences between the physicochemical properties between DF diesel fuel and B100 fuel apart from a significantly higher oxygen mass content in B100. The torque of an internal combustion engine is regularly higher for diesel fuel. The use of B100 fuel enables a measurable reduction in pollutant emissions. The working factor pressure in the cylinder is slightly lower when the engine is powered by B100. The relative heat release rate for B100 is slightly lower compared to DF diesel.

Steam Conversion of Ethane and Methane–Ethane Mixtures in Membrane Reactor with a Foil from Pd–Ru Alloy

The features of steam conversion of ethane and methane-ethane mixtures containing 5, 10 and 15% ethane in a membrane reactor with a 30 μm thick Pd–Ru foil at temperatures of 1800 and 3600 h–1 and steam/feed rations of 3 and 5 have been investigated. Comparative experiments with “non-membrane” reaction have shown that in the membrane reactor the feedstock conversion to form H2 and CO2 increases and ethane hydrocracking decreases. Increasing the rate of H2 recovery through the membrane by permeate evacuation leads to an increase in the yield of H2 and CO2. With a decrease in the steam/feed ratio from 5 to 3, the ethane hydrocracking and the rate of carbon deposits formation increases. Optimal conditions for steam conversion of ethane and methane-ethane mixtures are T = 773 K, feed space velocity of 1800 h–1 and steam/feed ratio of 5. The established regularities are similar to those obtained earlier for other types of raw materials (mixtures of methane with propane, propane, n-butane, a mixture simulating the average composition of associated petroleum gas) in this membrane reactor.

Recycling of plastic waste in the conditions of the Krasnoyarsk Territory

The analysis of the situation with the processing of plastic waste in the Krasnoyarsk Territory, carried out in the article, showed its low efficiency. Most plastic waste, of which 20 % is polyethylene terephthalate (PET), is not recycled and ends up in landfills. The main reason is the lack of enterprises engaged in full-fledged recycling. This exacerbates the difficult environmental situation in the region. The authors have developed and presented a plastic recycling project based on the principles of a circular economy. Based on the consideration of various processing methods (physical, chemical, thermal), the authors chose the mechanical processing of PET, which allows processing waste into recyclable materials suitable for the production of new products, for example, synthetic fibers. The choice of PET is due to its chemical resistance and high degree of impact resistance. The final product of processing is granulate (granules), as a technological and high-quality type of raw material. The technology for processing PET containers into secondary granulate includes the stages of sorting, pre-treatment of waste, crushing and washing. and granulation Advantages of the method: comparative simplicity of technological design and absence of emissions of harmful substances. The authors assessed the total investment costs of the project and calculated key financial indicators: net present value (NPV), internal rate of return (IRR), profitability index PI, which show the high efficiency of the project. The project can be extremely attractive for investors and recommended for implementation and replication. The article also calculated the break-even point, conducted a risk analysis, and built a risk matrix. a risk response strategy (avoidance strategy) is proposed.

The study of carbohydrates of corn raw materials

The aim. The aim of the study was to study the content of polysaccharide fractions depending on the dissolution, qualitative composition and quantitative content of sugars in corn silk, leaves and roots.
 Materials and methods. To study different fractions of polysaccharides - water-soluble polysaccharides (WSPS), pectin substances (PS), hemicelluloses A (HC A) and B (HM B) used a gravimetric method based on the extraction of polysaccharide fractions with a suitable solvent followed by sedimentation and weighing of the sediment. Determination of the qualitative composition and quantitative content of monosaccharides in corn medicinal plant materials (MPM) was carried out by the method of gas chromatography-mass spectrometry (GC/MS).
 Results. Conducted studies of corn silk, leaves and roots carbohydrates using the fractionation method indicate the following trend of BAS accumulation in the studied raw materials: the content of WSPS and PS in corn silk exceeded the content of these compounds in other types of raw materials – 4.07±0.14 % and 7.20±0.29 %, respectively; leaves accumulated the most HC A and HC B compared to the content of these fractions in other samples - 6.81±0.21 % and 21.20±0.84 %, respectively. It was established by the GC/MS method that 4 substances were identified in corn silk in the free state: arabinose, glucose, galactose and fructose. After hydrolysis 5 substances were identified in corm silk - arabinose, xylose, mannose, glucose, galactose. Among the free sugars 3 compounds were found in corn leaves - glucose, fructose and sucrose. After hydrolysis, 4 compounds were identified in in corn leaves – arabinose, xylose, glucose and galactose. In corn roots 3 compounds are found in a free form - glucose, fructose and sucrose. After hydrolysis 4 compounds were identified in corn roots - arabinose, xylose, glucose and galactose.
 Conclusions. The obtained results indicate a significant content of polysaccharides and sugars in the raw materials of corn, which makes it possible to predict the anti-inflammatory, detoxifying, adsorbing, energetic activity of the studied types of corn plant raw materials

Organizing effective competitive development of enterprises through the formation of a rational base of resource provision: methodological aspect

In order for enterprises not to suffer significant losses by repurposing their activities for the manufacture of products attractive at certain points in time, it is necessary to take into account the compatibility of resource mutual support of the business processes they perform when forming the product range. Such compatibility and interaction should ensure the long-term efficiency of the enterprise and the strategic attractiveness of its products on the market. Accordingly, the object of this study is the process that forms a rational resource base for effective long-term competitive development of the enterprise through the formation of an additional effect. Within the framework of the formed approach, the expediency to use the coefficient of managerial efficiency to choose the necessary source of resource provision (own production or alternative attraction of the necessary resources from an attractive stakeholder) has been proven. The proposed recommendations should be applied to enterprises that use a significant number of parts, assemblies, and components for production; therefore, they have been tested on the activities of a machine-building enterprise. The results confirmed the feasibility of independent production by the studied enterprise of the relevant types of raw materials and the provision of certain services. This made it possible, by rationalizing the assortment policy of the enterprise, to create a closed production cycle and reduce, thereby, its dependence on third-party enterprises, which is extremely relevant under wartime conditions. In addition, the implemented measures made it possible to increase the volume of production of a particular type of product (vacuum pumps) by 10 %, reduce the reserve of production capacity, and ensure the stability of competitive advantages by increasing the service life and quality of individual components of the existing goods of the studied enterprise

Post-Harvest Processing of Agricultural Products Supporting Local Wisdom in The 2022 Matching Fund Program

Traditional food processing has promising potential for development, due to the high dependence of the community on processed meat and fish products to meet the nutritional needs of the community. The traditional food processing is very complex and is based more on the conception of local wisdom which has been passed down from generation to generation. The characteristics of traditional food processing are the type and quality of raw and additional materials which vary greatly, and environmental conditions that are difficult to control. The processing process still has many shortcomings because it relied more on natural factors, the treatment was not measured quantitatively and had not implemented a hygiene sanitation program.

A meta-analysis to observe silage microbiome differentiated by the use of inoculant and type of raw material.

Silage fermentation is naturally carried out by lactic acid bacteria (LAB) to mainly produce lactic acid (LA) and other organic acids as preservatives. Along with fermentation time, the growth of LAB will replace and suppress undesirable microorganisms. This meta-analysis study aimed to explore silage microbiome differentiated by LAB inoculants and type of raw materials. A total of 37 articles with 185 studies and 475 datasets were used for building up the meta-database. Data were subjected to the mixed model methodology. The parameters observed were silage quality and silage microbiome post-ensiling process. Results revealed that four bacterial genera along with Weissella dominated the post-ensiling process. The addition of lactic acid inoculants in the silage has increased the abundance of Lactobacillus spp. and decreased the Shannon index significantly. Moreover, the abundance of both L. plantarum and L. buchneri increased, and subsequently, Weissella, Pseudomonas, Proteobacteria, pH value, ammoniacal nitrogen (NH3-N), coliforms, and the yeasts were decreased significantly due to the addition of LAB inoculants in silage (p < 0.05). Environmental factors such as temperature affected the existence of Pseudomonas, Exiguobacterium, and Acinetobacter. However, the dry matter, LA, acetic acid (AA), the ratio of LA to AA, and the LAB population were enhanced significantly (p < 0.05). Among the LAB types, the lowest abundance of Pseudomonas was due to the LAB group, while the lowest abundance of Weissella and Proteobacteria was due to the addition of the combined LAB group. In conclusion, the addition of LAB is effectively enhancing the silage microbiome and silage quality by altering bacterial diversity and the metabolic products of the silage materials for safe preservation.

Adaptation of the method for identification and quantification of sinigrin in mustard seeds

The research is devoted to the study on adaptation, verification and implementation of the method for determining sinigrin in mustard seeds and products of its processing, as well as in other types of food raw materials of plant origin. The relevance of the research is determined, on the one hand, by the need to control sinigrin in the technological processes of mustard processing, and, on the other hand, by the lack of effective standardized methods for determining sinigrin in the Russian Federation. The aim of the research is to modify and (or) adapt the most effective methods for the identification and quantification of sinigrin, presented in the publications of foreign researchers. The objectives of the study included construction of calibration graphs; modification of the sample preparation technique to reduce the complexity and duration of the analysis while maintaining the required parameters of accuracy and reproducibility; adaptation of the analysis method using high performance liquid chromatography; verification and approbation of the proposed method using real production samples, i.e. mustard seeds.High performance liquid chromatography has been used as the basic method.As a result of the research, the sample preparation technique has been modified. It has made it possible to reduce labor intensity and reduce the time for its implementation while maintaining the required metrological characteristics. The calibration dependence has been determined and a method for the identification and quantitative analysis of sinigrin in raw materials of plant origin using a high-performance liquid chromatograph equipped with a diode array and mass spectrometric detectors proposed. As a result of verification, the metrological characteristics of the proposed method have been determined: the measurement range is from 0.0005 to 10%, the accuracy index is ± 0.01%. The method has been tested on real objects, mustard seeds, which are the main sources of sinigrin. The proposed method for the identification and quantification of sinigrin can be recommended for use in research and production laboratories equipped with the necessary measuring instruments and testing equipment.
