- ДокументANALYSIS OF THE QUALITY OF FLOUR FROM DIFFERENT SYSTEMS OF THE TECHNOLOGICAL PROCESS OF A FLOUR MILL(2019) D. ZHYGYNOV, V. KOVALOVA, A. DRAGOMYR, H. ZHYHUNOVA, К. ZHANABAYEVAResearch in the article is aimed to determining the quality of flour from different systems of the technological process of a wheat milling. Samples of flour were obtained at the mill "Rivne Boroshno". Private enterprise "Rivne Boroshno" is one of the largest producers of wheat flour in the western region with a capacity of 180 tons /day. Flour obtained from various systems of milling process, has a very large variety of quality indicators. Whiteness, Gluten Deformation Index, Gluten Content, Protein Content, Ash Content, Water Absorbing Capacity, FN, SD, the rheological properties of dough on the Mixolab device, as well as the quality of baked bread have been evaluated.During the study, the variability of flour quality indicators on various systems was found. Whiteness varied – from 1 to 71 units, Gluten Deformation Index – from 40 to 100 units, Gluten Content – from 2 to 36 %, Protein Content – from 9,8 to 18,2 %, the FN – from 275 to 374 s, SD – from 15 to 30,3 UCD, Ash Content – from 0,31 to 2,23 %, Water Absorbing Capacity – from 53,5 to69,7 %. In the process of grinding grain and intermediate products, more than twenty flour streams of different quality are producedat the flour mill. From these streams it is required to receive only one or several grades of flour. Naturally, if only one variety is produced, then all flows from different systems are sent to it. The weighted average quality indicators of flour should comply with the requirements of the standard for this grade in terms of Ash Content, Gluten Content, etc.The maximum Ash Content is observed in the streams from the last reduction systems, as well as from break systems in the milling process, where products with a large number of brans are milled. At the same time, the flour from the central parts of the endosperm is slightly less gluten, but more starch than in the flour from the peripheral parts of the endosperm, which are grinding on subsequent reduction systems. For the research, samples of flour were taken from each system of the technological process. For convenience, we have arranged them for quality using the indicator of whiteness. One of the main indicators of the quality of flour, which determines its grade, is whiteness. In the studied samples, the values of the whiteness index range from 71 to 1 unit.
- ДокументASPECT OF MINIMIZATION AREAS OF «HUMAN FACTOR» IN LABOR SAFETY(2019) A. BOCHKOVSKYI, N. SAPOZHNIKOVAThe article analyzes well-known semantic interpretations of the term "human factor" in the context of the evolutionary development of the safety component in "man-machine-environment" systems. It has been ascertained that single, recognized by law term "human factor" still does not exists, but the majority of researchers attribute this phenomenon to the human psycho-physiological reaction to changes in the environment. It is noted that this approach is erroneous because the manifestations of "human factor" at the individual level of each person should be considered in the context of the features of its three main components - biological, social and informational. The trends of the evolutionary development of the technosphere and the analysis of statistical data on occupational accidents, as well as industrial breakdowns and disasters, prove the need to introduce positive changes at the level of the "human factor" components. First of all, it concerns the information component, as the development of technologies over the past decade is far ahead of the level of training in the field of occupational safety, which does not allow maintaining the required level of occupational safety and labor culture in the conditions of a new range of previously unknown hazardous and harmful production factors. It was emphasized that necessary positive changes in the components of the "human factor" should be implemented as a part of the concept of sustainable humanity development, which provides for the development of three interrelated areas: economic, social and spiritual growth of society. Thus, basic directions that will minimize the negative effects of the "human factor" within functioning of the future complex systems "man machine-environment", are to increase the level of motivation for safe human behavior at production facilities and to form safety priorities over economic outcomes of enterprise’s activity. The possibility to implement such directions directly depends on the implementation of the relevant reforms in the system of secondary, vocational and higher education, as well as occupational safety and industrial safety regulatory framework in Ukraine.
- ДокументCHLORELLA SUSPENSION AND ITS USAGE IN FINISHING PIGS’ RATIONS(2019) O. KARUNKYI, T. REZNIK, Ye KULIDZHANOVThe animal husbandry cannot develop successfully without complete balanced feed and optimal forage supply. This article deals with the chemical composition of chlorella suspension. The ration is balanced with seaweeds as well as premixes, vitamins and bio supplement for the last decades. These seaweeds include chlorella - a representative of green microscopic algae. The use of chlorella allows for multi-factor balancing of the diet in accordance with modern feeding standards, which increases the productive effect of feed and significantly increases the transformation of nutrients into livestock products. This is arelevant issue of modern animal husbandry. The chlorella suspension was material for scientific research. It was made on the farm “In Samvel”, Ovidiopol District. According to the result of researches that took place on the farm " In Samvel", Biliayevka District, Odessa Oblast and SERF "Yuzhnyi" OSAGES NAAS, new data concerning chemical composition, the positive influence of investigated chlorella suspension on the growth and development of finishing pigs as well as feed costs by 1 kg of growth were obtained. It has been established that the chemical composition of chlorella suspension takes a special place among all feed additives used in farm animals feeding. It has been established that the additional use of chlorella suspension in the ration of finishing pigs of Large White breeds contribute to the increase of average daily gains by 121.9% against the control group in which chlorella suspensions was not given. Feed conversion to obtain1 kg of pigs live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg and feed conversion index in the experimental group was higher by 21.4%. Thus the results of researches indicate the positive effect of investigated chlorella suspension on the growth anddevelopment of finishing pigs. Due to the obtained results, we can state that the chemical composition of the suspension chlorella takes a special place among all feed additives used in farm animals feeding. Chlorella has higher indicators of chemical composition, the amount of protein, vitamins and minerals in comparison with plant fodder and crops of agricultural production.
- ДокументFEATURES OF CORN CONSUMPTION IN THE FOOD PRODUCTION INDUSTRY(2019) O. SHAPOVALENKO, L. KUSTOVThis paper presents the features of corn as raw material for groat industry. Corn is used in many segments of the food andprocessing industry. corn is processed for traditional food products — groats, flakes, flour, extruded foods, and other corn byproductsare widely used for the production of dry breakfast cereals, snacks, cereal bars. In terms of using of the advanced processingtechnologies, the industry produces starch, gluten, and germs. Corn germ is used to produce the high-value vegetable oil, aswell as starch — for both food and non-food purposes. More than half (65%) of corn is used for feed purposes, 25% –technical purposes,and nearly 20% – for various types of food production. corn is processed for traditional food products — groats, flakes, flour,extruded foods, and other corn by-products are widely used for the production of dry breakfast cereals, snacks, cereal bars. For thecolour, corn is divided into white and yellow types. According to the literature data analysis, yellow corn is more used in China,Argentina, Brazil, while white corn — in some countries of Asia, Latin America, and the Balkan countries. Depending on itsmorphological features, the corn kernelis divided into various groups, species and subspecies.In Ukraine corn kernel is classified into 8 types, with separately defined limitations on the content of the major crop in thebatch, grains of other type, etc. Corn of І-VІІІ types with the quality indicators specified in the standard, for the production of foodproducts. Flint and dent corn types are the most applied grain varieties in the industry, they are widely used in the production segmentof food and feed products. Sweet corn is widely used as a vegetable crop in the food canning, food concentrates, starch andbrewing industries due to its flavor properties. Popped corn is not only the most convenient raw material for the production of popcorn,but it also can be used as the raw material for the production of corn curls and dry breakfast cereals By analyzing the weightfraction of fat in kernels of different corn varieties we can note that the lowest number of fat is typical for popped corn (4.0%) andthe largest – for sweet corn (9.1%); dent and flint corn have the same total fat number (4.5-4.9%).Test weight of corn types – poppedcorn ranges within 712-826 g/l, dent corn - 875-893 g/l, and flint corn - 768-786 g/l. The weight of 1000 kernels of corn dependingon the varieties changes within 150-600 g.
- ДокументRISK-ORIENTED APPROACH TO LABOR PROTECTION AT GRAIN PROCESS ENTERPRISES(2019) O. FESENKO, V. LYSYUK, Z. SAKHAROVAThe article focuses on the introduction of a risk-oriented approach to labor protection at the enterprises of the grain processing industry. Such an approach is imperative in modern conditions in accordance with the Concept of reforming the system of labor protection management. This will involve the introduction of the proactive principle of “preventive actions” (prevention of hazardous events and situations) instead of the existing reactive principle of “corrective actions” (response to hazardous events and situations). A risk-oriented approach to occupational safety and health is the basis for the formation of a new national system for prevention of the operational risks. In the grain process enterprises, which have agreed their policy on labor protection with international standards, there has been an increase and improvement of the responsibility and competency of the ordinary employees and managers in the safety field, the risk of on-the-job injury has decreased. Improvement of the system of labor protection and risk management at enterprises should be carried out according to State Standard (DSTU) ISO 31000:2018 “Risk Management. Guidelines (ISO 31000:2018, IDT))”. The purpose of the standard is to reduce operational risks to an acceptable level. The main stages of the risk management process are presented. Identification of hazards, risk assessment, definition of security measures is a constituent and integral part of such a system. This is necessary to identify and understand the dangers that may arise in the course of an enterprise's activity, to assess the risk arising from a particular hazard, and to take measures to reduce the probability of occurrence of hazards. At the enterprises of the grain process industry, the identification of hazards consists in the definition of all objects, situations or actions (or their combination) that are inherent in an enterprise's activities and present a potential threat to the health and life of workers. At the same time, the different types of works and situations are considered in order to identify the dangers that are constantly present in normal working conditions, as well as the hazards, the impact of which is possible in case of deviation from normal working conditions and emergencies. Examples of possible hazardous factors at such enterprises are given. The adequacy of the existing security measures, the need for heir improvement or the introduction of other security measures are determined based on the results of the risk assessment.
- ДокументSTUDY OF MOISTURE ABSORPTION OF SWEET CORN GRAIN OF DIFFERENT FRACTIONS(2019) S. SOTS, O. BUNYAKIn Ukraine, as the raw material for the production of cereals, flour, flakes, the following main crops are used: wheat,barley, buckwheat, oats, corn, rice, millet, peas. The volume of world grain production has grown significantly in recentyears. In Ukraine, corn is the main fodder crop, and only a small amount is used as a food. Corn has the leading place amongthe major grain crops in world agricultural production. Corn grain production is concentrated in warm regions. In some regions,corn is the basis of the traditional nutrition of the population, but basically it forms part of the feed in the feeding offarm animals.Today about 3500 food and technological products are produced from corn. Corn can largely satisfy the needs oflivestock, its share is almost 30% of concentrated feed. With the advent of new directions in the development of biotechnologyin the world, the significance of this culture will increase even more. The programs of biofuel production are gaining momentum,in connection with which a significant expansion of the sown area under the corn is foreseen.In this article features of water-heat treatment of corn grain during preparation for processing are provided. Featuresof the use of hot and cold grain conditioning in the cereal industry are considered. In the course of this study, it wasdetermined that the optimum water temperature for humidifying corn sugar is 60 ºС. Using a certain water temperature duringhumidification will enable to perform more efficiently the directed change of technological properties of grain, to ensurethe high efficiency of its further processing. The results of research of the water absorption capacity of sugar corn grain arepresented. As can be seen from the research carried out to improve the efficiency of the STI and optimize the processing technology,the grain lots are fractionated into more homogeneous flows of physical properties and treated separately.
- ДокументSTUDY OF PHYSIOLOGICAL PROCESSES IN CORN GRAIN DURING STORAGE UNDER HERMETIC CONDITIONS(2019) A. BABKOV, М. ZHELOBKOVAIn recent decades, in addition to the traditional grain storage in dry conditions, the technology of grain storage without access of air - in hermetic conditions has gained a widespread in polymeric grain bags (silobags). The aim of the research was to study the regularities of the physiological processes of respiration in maize grain when stored in hermetic conditions, which would determine the terms of safe storage of different humidity grain in polymeric grain bags and reduce the costs of its processing and storage. The object of research is the technology and processes of freshly harvested corn grainstorage. As the main subject of the study, a dent-type hybrid of corn DKS 3705 was used, which, according to its botanical and agronomic properties, was better for use on food and non-food needs and for export. On the basis of the conducted researches it was established that with an increase in initial moisture of grain from 14% to21% and subsequent storage in hermetic conditions at constant temperatures the natural losses of dry matter of grain increase in comparison with losses of dry matter of grain with standardhumidity (14%), in particular, at a temperature of 18 ºС by 112%, at a temperature of 11 ºС by 296% and at a temperature of 4 ºС by 123%. Thus, it is shown that the decrease of the temperature regimes of grain storage of maize with different initial humidity under hermetic conditions contributes to the reduction of the intensity of thenatural physiological processes in it and, consequently, the natural losses of its dry matter. It has been established that during storage of corn grain for three months and reduction of temperature storage conditions from 18 ºС to 11 ºС in samples of grain with an initial humidity of 14% decrease: the absorption rate of oxygen by 34%, carbondioxide emissions, loss of dry matter and the production of thermal energy by 66%. For a grain with an initial humidity of 21%, the reduction in intensity under the same conditions is: for absorption of oxygen 22%, the production of carbon dioxide 28%, losses of dry matter 37% and the production of thermal energy 23%. Reducing the storage temperatures of corn from 11 ° C to 4 ° C in samples of grain with an initial humidity of 14% reduces the intensity: absorption of oxygen by 79%, carbon dioxide generation by 60%, dry matter loss by 60%, and the generation ofthermal energy by 60%. For grain with an initial moisture content of 21% under the same conditions, the intensity decreases: oxygen absorption by 28%, carbon dioxide generation by 77%, dry matter loss by 77%, and heat generation by 77%. Established regularities of the physiological processes in corn grain with different initial humidity when stored in hermetic conditions at different temperatures, it is possible to predict the characteristics of gas exchange processes in the grain mass, natural losses of dry matter and the generation of heat during storage of grain.
- ДокументTHE CHARACTERISTIC OF COMPOUND FEEDS FOR CLARIAS GARIEPINUS(2019) B. IEGOROV, L. FIHURSKA, М. TERZI, O. RUHLENKOThe article states that industrial fish farming in inland waters has become increasingly important in the recent years and it is one of the sources for satisfying the needs of people in the high-protein foods. The fish meat is an extremely rich source of proteins, which are easily digested, vitamins, polyunsaturated fatty acids, macro- and microelements. One of the priorities of the development of the fish farming in Ukraine is the cultivation of the Clarias gariepinus. Clarias gariepinus or African sharptooth catfish is a species of catfish of the family Clariidae, the airbreathing catfishes. In 2017, with the support of the Ukrainian State Agency, the Institute of Fisheries of Ukraine on the part of the state and the companies Vismar Aqua, Aquaprom and the Dutch company Trouw Nutrition («Skretting»), the program was developed to increase the cultivation of the Clarias gariepinus under the name Clarias gariepinus - 2020. The objective of the program is to provide 2020 tons of Clarias gariepinus until 2020. Today, the production of the Clarias gariepinus in Ukraine is about 500 tons per year; about50 farms are engaged in cultivation. That is why the production of balanced domestic compound feeds for Clarias gariepinus is an important task of the feed industry of Ukraine. The theoretical study was devoted to the problem of the production of compound feeds for the Clarias gariepinus. The nutritional value of compound feeds for Clarias gariepinus a depends on the stage of the life cycle of this species of fish. The above world leaders are manufacturers of compound feeds for Clarias gariepinus, the analysis of granule size and nutritional value of compound feeds on the content of crude protein in prestarting, starting, growth and finishing periods respectively. The requirements for the content of essential and non-essential amino acids, minerals (micro and micronutrients), waterand fat soluble vitamins and restrictions on the content of crude fiber are given. Indicated the main and additional raw materials, traditionally used in the manufacture of data feed advanced companies. The main components are fish meal, produced under relatively low drying conditions, wing meal, corn and wheat gluten, soy products, by-products of extraction oil and press production oil (soya, sunflower and other cakes and meals), premisex, carotenoids like astaxanthin. The feeding programs of the Clarias gariepinus of various manufacturers have been analyzed and their own feeding program has been developed for this species of fish; it divides the period of cultivation of the Clarias gariepinus into prelaunch, starting, growth and finishing ones. For prestart mixed feeds, the content of crude protein should be at least 45%, raw fat at least 12%, raw fiber not more than 1.8%, gross energy not less than 13.7 MJ, raw ash not more than 8%. For starter feed, the content of crude protein should be at least 42%, raw fat at least 12%, raw fiber not more than 3%, gross energy not less than 13.1 MJ,raw ash not more than 9.5%. For grower’s feeds, the content of crude protein should be at least 38%, raw fat at least 12%, crude fiber not more than 3%, gross energy not less than 12 MJ, raw ash not more than 9.5%.
- ДокументUSING OF BIOTESTING IN SAFTY ASSESMENT OF THE EXTRUDED FEED ADDITIVE WITH ALGAE(2019) A. MAKARYNSKA, N. VORONAThe article is devoted to the problems of determining quality and safety of extruded feed additive (EFA) with algae. It is used in the production of mixed feed and premixes. It is proved that the safety of finished food products depends on the safety of feed and feed raw materials. The list of conditions for obtaining safe finished products is given. Today traditional methods of analytical chemistry, express and toxicological methods (marking, biotesting) are used for the analysis of feed safety. The expediency of use of brown algae in the composition of feed products is substantiated. The brightest representative ofbrown algae is Laminaria. The technology of using Laminaria algae in the composition of feed products in the form of extruded feed additive is proposed. The method of determination of organicity by methods of biotesting is given: biocrystallization method, determination of the oxidation-reduction potential index (ORP), organicity using Colpoda steinii culture. Indicators of organicity are given. An analysis of experimental samples biocrystalograms suggests that EFA is environmentally safe and do not endanger the environment or the health and life of animals and humans. When determining the ORP of the EFA with algae it was established that the product is easily digestible, since it has a biological compatibility with the animal organism. The expediency of using the process of extrusion to reduce the toxicity of algae is established. The application of the extrusion allows to add up to 15% Laminaria algae to the feed. The results of biological studies of EFA in vivo are presented, which indicate a high biological efficiency of the use of algal feed supplement in the composition of feed for young farm birds in the amount of up to 25%, since the average daily weight gain of rats increases and the cost of feed decreases.
