Документ Determination of the celluloseand lipid-containing components influence on the extrudate technological indicators(Технологічний центр, 2024) Petik, Ihor; Litvinenko, Olena; Stankevych, Serhii; Zabrodina, Inna; Ponomarova, Maryna; Kotliar, Oleh; Kliuchko, Ruslan; Muhalenko, Oleksii; Pidpala, Tetiana; Danylchuk, GalynaThe effect of cellulose- and lipid-containing components on the technological parameters of the extruded mixture based on protein- and starch-containing raw materials on the technological parameters of the extrudate was studied. The use of components that modify such technological indicators of the extruded mixture as water resistance and swelling is substantiated. It is proposed to use sunflower husks and sunflower phosphatide concentrate as modifying additives to the mixture for extrusion. A rational ratio of the specified components in the extrudate was established to obtain indicators of water resistance in the range of 220...300 min and swelling in the range of 100...120 %. This is an important aspect of expanding the range of extruded products from the waste of oil and fat industries and obtaining high-quality competitive products. The object of the study is the dependence of water resistance and swelling of the extruded mixture on the content of modifying additives. Their rational ratio in the extrudate is: sunflower husk – 6.0 %; sunflower phosphatide concentrate – 5.0 %. The manufactured extrudate sample corresponds to commercial fish feed in terms of chemical composition and technological parameters, and also has a 4 times lower cost. A feature of the obtained results is the possibility of regulating the water resistance, swelling and porosity of the extrudate based on proteinand starch-containing raw materials, depending on the ratio of cellulose- and lipid-containing modifying additives. This allows to change the technological parameters of the finished product depending on the chemical composition of the mixture of raw components according to the requirements of the consumer. The results of the conducted research prove that cellulose- and lipid-containing secondary products of production can be successfully transformed into new competitive products.Документ Development of extruded animal feed based on fat and oil industry waste(Технологічний центр, 2023) Petik, Ihor; Litvinenko, Olena; Kalyna, Viktoriia; Illinska, Olha; Raiko, Valentina; Filenko, Olesia; Lutsenko, Maryna V.; Romanova, Tetiana; Svishchova, Yana; Ivakin, OleksiiThe paper considers the way to solve the problem of processing waste from the oil and fat industry, namely sunflower and soybean meals, which are a source of many valuable substances. The peculiarity of the work lies in determining the rational ratio of the base components of extruded animal feed, which is an important aspect of obtaining highquality competitive products. The research object is the use of oil and fat industry waste in extruded animal feed technology. The rational ratio of the components of extruded animal feed has been determined. The rational ratio of animal feed components is: sunflower meal – 0.40 parts by weight; soybean meal – 0.25 parts by weight; oatmeal – 0.35 parts by weight. The animal feed sample with justified composition corresponds to the commercial analogue in terms of porosity (72 % and 76 %, respectively) and cost ($285/t and $285/t, respectively). In addition, the extruded feed with the developed composition exceeds the commercial analogue in terms of protein content by 3.2 times and essential amino acids content by 2.9 times. The obtained data are explained by the use of a complex of components, namely oil and fat waste and starch-containing grain raw materials with various limiting amino acids and various technological features of the extruded mass of their mixture. The feature of the obtained results is the possibility to control the technological characteristic (porosity) of the finished product depending on the components ratio, which allows changing product characteristics according to consumer requirements. The research results make it possible to efficiently process secondary products of oilseed processing into a new competitive marketable product. From a practical point of view, the technology makes it possible to reduce the cost of storage/utilization of industry waste, get additional income from new products sales and improve environmental conditions. The applied aspect of using the scientific result is the possibility to create a range of animal feed with different technological indicators depending on the components ratio.Документ Technology of culinary (frying) fats(Scientific Route, Estonia, 2020) Udovenko, Oleksiy; Gladkiy, Fedir; Shkredov, Ivan; Havriushenko, Kateryna; Litvinenko, Olena; Kunitsia, KaterinaThe increased popularity of deep-fried foods has put health and safety concerns on the agenda. Factors that affect the quality and safety of culinary (frying) fats include the fatty acid profile, as well as cooking modes and time, especially when renewal rates are low. The industry is currently facing a top-of-mind technology challenge: to reduce the “oil content” of fried foods by developing a frying fat that would meet up-to-date food production standards. In other words, there is a need for a frying fat, which should last as long as possible without oxidizing and changing colour. Furthermore, its uptake by foods, fried in it, must be 40–50 % less than that of conventional fats. To this end, the authors put forward an innovative technology for producing culinary (frying) fats through esterification of fatty acids with high molecular weight alcohols. The research work that has been carried out so far prove the possibility of producing specialty fats by such modification to the applicable regulatory requirements: the melting range is between 29.6 and 34.65 °С, the acid value is up to 0.4 mg KОН/g. The viscosity of modified fats is lower than that of oils, which is due to the fat structure, and this circumstance will have a positive effect on the fat content in a finished product. The researchers has identified a numerical relationship (expressed as a regression model) of the yield of the desired fraction of a modified fat versus the ratio of reagents, reaction time, and process temperature, as well as calculated rational process parameters. The aim of the research is to develop the technology of obtaining culinary (frying) fats by esterification of fatty acids with high molecular weight alcohols.Документ Analysis of the influence of technological parameters of the chlorogenic acid extraction process from sunflower meal on the degree of its extraction(Технологический Центр, 2020) Labeiko, Marina; Gladkiy, Fedir; Bochkarev, Sergiy; Mazaeva, Viktoria; Litvinenko, Olena; Ovsiannikova, Tetiana; Zhyrnova, Svitlana; Sytnik, NataliaThe object of research is the efficiency of extraction of chlorogenic acid ‑ the natural antioxidant, depending on the conditions of its extraction from sunflower meal. The main problem of this issue is the fact that the extraction degree of the specified phenolic compound is influenced by many factors, such as the degree of grinding of the product, the type of raw material, the method of extraction, the nature of the solvent-extractant, the temperature and duration of the extraction process, the hydromodule in the system "raw – extractant" etc. The impact of each of these parameters requires careful consideration and appropriate research. This will determine the optimal values of the specified parameters of the extraction process and increase the efficiency of extraction of chlorogenic acid. In this work, the raw material for the production of chlorogenic acid is a meal made from sunflower seeds – a cheap second raw material of oil and fat production. Previous studies have found that a high-efficiency extractant of the specified antioxidant is a solution of ethyl alcohol with a concentration of 60 %, and the optimum temperature of the process of extracting chlorogenic acid from sunflower meal is the boiling point of the extractant. As a result of this study, the regularity of the influence on the extraction degree of chlorogenic acid of such technological parameters as the hydromodule in the system "meal – ethyl alcohol solution 60 %" (hereinafter referred to as "meal – extractant") and the duration of the extraction process were studied. Experiments to determine the dependence of the extraction degree of chlorogenic acid on the hydromodule in the system "meal – extractant" and the duration of extraction were carried out in accordance with the plan of the full factor experiment. Mathematical methods using the Microsoft Office Excel 2003 (USA) and Stat Soft Statistica v6.0 (USA) software packages have been applied for experiment planning and data processing. The dependence indicated in the paper is a quadratic function that predicts an increase in chlorogenic acid content during extraction, with an increase in the hydromodule in the "meal‑extractant" system from 1:5 to 1:10 and a decrease in the extraction time from 60 minutes up to 30 minutes. It is established that for the maximum possible increase in the extraction degree of chlorogenic acid from the meal of sunflower seeds, the optimal value of the hydromodule extraction ‑ 1:10, the duration of extraction ‑ 30 minutes. The obtained results allow to increase the extraction degree of chlorogenic acid from sunflower meal from 2.46 % to 5.58 %. This indicates the possibility of increasing the efficiency of extraction of antioxidant more than 2 times.
