    (2024) Polishchuk, Galyna; Sharahmatova, Tetiana; Marynin, Andriy; Ivashchenko, Olga; Sviatnenko, Roman
    Expanding the assortment of low-fat yogurt with natural structuring sweeteners and regulated quality indicators is an actual direction of scientific research. The purpose of the study is to study the patterns of influence of the products of enzymatic hydrolysis of corn starch with different dextrose equivalents on the rheological, physical and chemical characteristics of yogurt. Тhe functional and technological properties of starch products of different chemical composition were studied – maltodextrin MD-10, glucose syrup IG-42 and glucose-fructose syrup GFS-42. The possibility of completely replacing dry skimmed milk and sugar in the composition of yogurt with a fat content of 1% drinkable with an equivalent content of dry substances of maltodextrin MD-10 and glucose syrup IG-42, which ensure the formation of rheological characteristics inherent high-quality yogurt. Yogurt with sucrose, which inhibits the organization of macromolecular chains of milk proteins, has the lowest thixotropic ability, and yogurt with maltodextrin MD-10 and glucose syrup IG-42 has the highest. The predominance of higher sugars in the composition of MD-10 maltodextrin lengthens, and the increased content of monosaccharides in GFS-42 accelerates the duration of fermentation of milk mixtures in the technological process of production of yogurt with a fat content of 1.0%.

    Physico-chemical and rheological indicators of meat pates with corn starch suspensions prepared with electrochemically activated water
    (2023) Marynin, Andriy; Shpak, Vladyslav; Pasichnyi, Vladyslav; Sviatnenko, Roman; Shubina, Yevgenia
    The aim of the study was to determine the influence of electrochemically activated water application on the rheological properties of corn starch suspensions and pates prepared with them. Corn starch suspensions were prepared on artesian water, which was activated by electrochemical treatment on a diaphragm electrolyzer. Physico-chemical characteristics of electrochemically activated water were determined using a Palintest 7500 photometer. Morphological studies of starch granules were carried out by scanning electron microscopy, and granulometric composition was determined by laser diffraction method. The rheological indicatorss of starch suspensions and pates were studied using a Kinexus Pro+ rheometer. The physico-chemical characteristics of electrochemically activated water except pH met the requirements of the European Parliament and Council Directive on the quality of water intended for human consumption. The water absorption capacity of starch when preparing its suspensions on a catholyte (obtained by passing a direct electric current through water in the cathode chamber of an electrolyzer) decreased by 26%, and when prepared on an anolyte (obtained in the process of water oxidation reactions on the anode) increased by 18%. The moisture holding capacity of hydrated starch decreased by 10% when using catholyte, and increased by 36% when using anolyte. Electrochemically activated water had a significant effect on the rheological characteristics of starch suspensions: with an increase in the percentage of complex shear strain, the shear stress increased proportionally for samples of suspensions made on electrochemically activated water. The viscoelastic properties of starch suspensions prepared using electrochemically activated water both at 25 ℃ and at 68 ℃ tended towards an ideally elastic gel, that is, they had more elastic structure than the control samples. Under the action of shear deformation, the elastic properties were lost, while the suspensions acquired viscosity (phase angle values increased). The maximum value of the moisture binding capacity of pates was observed when using a starch suspension prepared on anolyte. The best values of rheological characteristics of pates were obtained when using starch suspension with 2% starch prepared on anolyte. Electrochemically activated water had a significant effect on the physicochemical and rheological properties of semi-finished products, in particular corn starch suspensions, and pates prepared with them, and contributed to better structuring of the studied food systems.

    Influence of electrochemically activated water on the physical properties and rheological indicators of meat pates
    (2023) Marynin, Andriy; Pasichnyi, Vasyl; Shpak, Vladyslav; Sviatnenko, Roman
    The object of research is the physical properties and rheological indicators of meat pates with corn starch suspen-sions prepared with activated water. Among the components of the composition of drinking water and food products, there are many substances with particularly inherent biological activity. The biological activity of water is caused by increased electronic or proton activity. Today, various ways of changing properties of water are known, but the most promising reagent-free method is the electrochemical activation of water. As a result of electrochemical treatment of water with an electric current, its electrochemical characteristics change. As a result, electrochemically activated aqueous solutions (catholyte/anolyte) are obtained; the water is saturated with oxygen, accelerates the removal of metabolic waste and promotes the most complete assimilation of nutrients.The research was aimed at determining the influence of activated water in the composition of starch suspen-sions on the physical properties and rheological indicators of meat pates with their content. Activated water affects the pH value of pates, which in the meat industry indicates the freshness and quality of meat raw materials and products made from them. Before pasteurization, the pH value for all samples was practically identical. That is, at the initial stage, activated water does not affect the acidity of pates. In the process of storage, the concentration of (H+) ions increases in pates, and the pH shifts to the acidic side. Water activity indicators of pates with starch suspensions on activated water gravitate towards the indicators of pates more than to the indicators of starch, the range for which is within 0.280–0.400. The dependence of the change in shear stress on the relaxation time of pates showed that regardless of the dosage of the starch suspension, the values of the shear stress of the samples on the catholyte in the time range 0–300 s are significantly higher than the values of the samples on the anolyte and tap water. This is explained by the ability of these samples, having acquired the necessary structure, to be less exposed to the external influence of deformation and to keep the structure more intact. The creep curves of all samples testify about the trimodal nature of the classical experimental creep curve. Thus, the electrochemical activation of water modifies the properties of corn starch and significantly affects the rheological indicators of meat pates containing it.The obtained results can be used in the development of recipes for meat pates and their production at enterprises.

    Influence of starch products on the vitality and activity of lactic acid bacteria in yogurt
    (2024) Ivashchenko, Olga; Khonkiv, Myroslav; Stabnikov, Victor; Polishchuk, Galyna; Marynin, Andriy; Buniowska-Olejnik, Magdalena
    The influence of starch product with different dextrose equivalents addition on the viability and activity of lactic acid bacteria Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus during fermentation and storage of yogurt has been studied. An increase of dextrose equivalent and monosaccharides content in starch products reduce the fermentation time of milk due to the increase of lactic acid bacteria activity. A slight decrease in water activity in the presence of glucose-fructose syrup in yogurt in an amount of 9% had virtually no effect on the milk fermentation process. The number of lactic acid bacteria increased during the first seven days of yogurt storage added with glucose-fructose syrup. On the 14th day of storage, the concentration of cells of S. thermophilus and L. delbrueckii ssp. bulgaricus became almost the same in all yogurts due to almost complete consumption of carbon sources. When the storage of yogurt was extended to 28 days, the most stable content of lactic acid bacteria was found in yogurt added with maltodextrin due to its prebiotic properties. The increases of active acidity and syneresis in all yogurts were greatest in the first 8–14 days. Presence of dextrins in yogurt stabilizes its physical and chemical properties during storage

    (2023) Gavva, Oleksandr M.; Kryvoplias-Volodina, Liudmyla; Marynin, Andriy; Tokarchuk, Serhii; Blazhenko, Serhii; Volodin, Oleksandr
    A qualitative analysis of the process of packaging liquid products (non-carbonated drinking water) using the example of a hybrid mechatronic dosing and packaging module was performed. The computer model of the mechatronic module is described by the basic operators of the Simulink program, taking into account the differential equations for changing the technological parameters of liquid dosing and the accepted initial and boundary conditions of the process. The modes of operation of the hybrid mechatronic dosing and packaging module are programmed using the driver. The boundary conditions of the process of formation and extrusion of the dose of the product are taken into account. The control system of the module is arranged on the principle of feedback and a sharp change in pressure in the portion receiver (from excess, within 3 bars to rarefaction up to –850 mbar). The analysis of individual stages of the dosing process is described, followed by the elaboration of accepted assumptions. During the tests of the computer model of the hybrid mechatronic dosing and packaging module, the accuracy of repetitions of dose formation was determined within ±0.22 % and 0.9 % of the set value of the dose mass of 50…200 ml. An experimental bench was designed, which could provide an opportunity to check the results obtained from the computer model. The research results would allow using digital control and measuring equipment to check the accuracy of dosing of the product from 50 ml to 200 ml. In the course of computer simulation, the effects of the given parameters of the dosing process on the accuracy of the product dose formation were determined, as well as the laws of the necessary distribution of compressed air pressure were formed to maintain the given productivity. The research results could make it possible to improve the designs of liquid product dosing modules and to determine the input parameters for field studies.

    Research and comparative analysis of the qualitative parameters of food powders produced from grain raw materials using an improved jet mill
    (2022) Changgao, Sun; Olkhovikov, Oleh; Xiaojin, Gao; Marynin, Andriy; Sichen, Zhang; Shevchenko, Anastasiia; Botong, Sun; Yue, Zhao; Marynin
    The object of the study is samples of food powders obtained by grinding the products of the collection and processing of a number of grain crops, using air-grinding technology in an improved jet mill. One of the most important problems of the modern food industry is that for the production of flour from cereals endosperm is used while the most important nutrients are found in shells and the germ of the grain. As a result of its grinding in conventional mills, common at existing mills, large pieces of bran and a large variation in the particle size of the grinding products are obtained, and this method is energy-intensive. According to the authors, the best solution to ensure truly whole grain grinding – that is, grinding grains with shells – is air grinding in jet mills. An improved jet mill makes it possible to grind both endosperm and grain shells into flour of the same consistency. From the same amount of raw material, therefore, it is possible to produce approximately 30 % more final grinding products. It is also important that the improved jet mill, under proven conditions, spends no more energy for grinding than a conventional mill. For research, the most popular products ground in such a mill were taken – wheat flour (black grain), buckwheat flour (from roasted buckwheat) and wheat bran. The first two products are whole grain milled, and the bran is produced from the collapse of wheat grown in accordance with the requirements of organic farming. Samples of powders obtained by grinding these products in an improved jet mill were compared with control samples – produced from similar raw materials in a roller mill – the most common design in service with mills. Physical indicators of the powders, thermophysical properties and biotechnological parameters were carried out. The obtained results allow to state that whole grain grinding produced on an improved jet mill has the characteristics better or close to standard types of flour produced on conventional mills. It allows them to be used without significant changes in the formulation of products with their addition (bakery, pasta, etc.), and also to create new dietary, healthy products rich in biologically active substances

    (2021) Bozhko, Nataliia; Pasichnyi, Vasyl; Tischenko, Vasil; Marynin, Andriy; Shubina, Yevgenia; Strashynskyi, Igor
    Meat-containing bread with the use of hemp flour has been devised, with the subsequent assessment of its physical and chemical, sensory properties involving the study into the technological indicators of new products. Three experimental formulations for meat-containing bread were developed, which included semi-fat pork, poultry, mechanically deboned turkey, pumpkin pulp, and 8, 10, 12 % of hemp flour. A meat-containing bread from combined raw materials was adopted as control. All samples were evaluated taking into consideration their physical and chemical, technological, and sensory characteristics. It has been proven that the addition of hemp flour to the formulation improved the consumer value of products by increasing the content of protein, fat, and minerals. It was found that the protein content in the developed products was 18.03‒19.53 g/100 g, which is 3.21‒11.80 % higher than that of the analog. The fat content increased by 17.84–56.83 %, which also led to an increase in the calorie content of products. It has been experimentally confirmed that the introduction of hemp flour into bread's minced meat improves the functional and technological indicators of model meat systems. An increase in water-binding capacity was observed, by 13.46‒22.15 %; in water-holding capacity, by 10.34‒21.43 %; in fat-holding capacity, by 17.2‒26.9 %. The combination of semi-fat pork, poultry, mechanically deboned turkey, and hemp flour increases the ductility of the minced meat while reducing the shear stress, contributes to the good forming properties of the minced meat. The sensory analysis of the prototypes showed their high consumer value. The organoleptic assessment and sensory analysis of the prototypes demonstrated high consumer properties of the manufactured products, which makes it possible to recommend them for inclusion in the diets of various segments of the population.

    Biosynthesis and characteriсtics of silver nanoparticles obtained using Saccharomyces cerevisiae М437
    (2021) Skrotska, Oksana; Kharchenko, Yevgen; Laziuka, Yuliya; Marynin, Andriy; Kharchuk, Maksym
    Due to the wide antimicrobial spectrum, silver nanoparticles (AgNPs) have great potential for use in the food industry to control foodborne pathogens. The culture supernatant and cell-free aqueous extract from biomass Saccharomyces cerevisiae M437 were used for the synthesis of AgNPs. The fact of the synthesis of biogenic AgNPs was confirmed by analysing the absorption spectra of the samples in the range of 200-700 nm. The size and zeta potential of AgNPs were determined using Zetasizer Nano ZS. The morphology of nanoparticles was examined using electron microscopy. Using spectral analysis in the UV-visible region, it was confirmed the formation of AgNPs in the investigated solutions. A pronounced absorption peak of AgNPs obtained using a cell-free aqueous extract from S. cerevisiae M437 was recorded in the wavelength range from 300 to 540 nm with a peak at 425 nm. For nanoparticles obtained using the supernatant, a widening spectral range of absorption was observed, which may be associated with the aggregation of AgNPs. AgNPs synthesized using the supernatant S. cerevisiae M437 had a spherical shape with a diameter of about 15 nm. The polydispersity index (PdI) of AgNPs solutions was 0.3, and the zeta potential was 13.6 mV. After storage for 45 days at 4 °C, the PdI value increased 1.6 times, and the zeta potential increased by 11.7 %. This may indicates a possible change in the shape of AgNPs, the formation of an agglomerate, or other processes that takes place in a colloidal solution during storage. AgNPs that were obtained using a cell-free aqueous extract from biomass of S. cerevisiae M437 had an oval shape with a size of 21.3×14.2 nm. The PdI and zeta potential values were similar to the nanoparticles obtained using the supernatant. However, after storage, these values differed significantly: the value of PdI increased 1.3 times, and the zeta potential decreased by 29%. So, the solution of silver nanoparticles obtained in this way is more stable after storage under the specified conditions. The possibility of extracellular synthesis of silver nanoparticles using the yeast Saccharomyces cerevisiae M437 has been shown. The shape, size, and zeta potential of biogenic AgNPs are described and their stability after storage is proved.

    Determining the properties of chia seed meal gel
    (2021) Strashynskyi, Igor; Grechko, Victoria; Fursik, Oksana; Pasichnyi, Vasyl; Marynin, Andriy
    Potential areas of using chia seeds meal as part of mincemeat semi-finished products were substantiated. The modern stage of development of the food industry involves the expansion of the range of natural functional ingredients that improve the organoleptic characteristics of finished products and provide consumers with “healthy” food. This causes the use of new ingredients in the meat processing industry for producing and devising products. The relationship between the indicators of emulsifying capacity, emulsion resistance, and the degree of hydration of chia meal was determined experimentally. It was found that the ability of chia meal to absorb and retain water and fat molecules in the emulsion composition decreased proportionally to a decrease in its concentration in the composition of hydrated samples. The existence of non-polar side chains of amino acids that get bound to fat molecules contributes to an increase in the indicators of emulsifying capacity and emulsion stability during heat treatment (70±2 °C) and after pre-freezing on average by 7–8.7 % and by 16–18.8 %, respectively. Analysis of effective viscosity of the dispersed system of chia seeds meal indicates that in the area of a higher concentration, the viscous-elastic and solid-like behavior of the suspension depends on dynamic changes in the volume of the phase of particles. Heating the experimental samples to a temperature of 70±2 °C in the center leads to a maximum increase in viscosity of the formed dispersions. When studying the effect of the processes of freezing on the properties of the studied systems, the cryoprotective properties for the proposed additives were detected. The obtained data indicate the thermal stabilization of the proposed additive, the ability to form a microgel structure in the finished product, and retain moisture during heat treatment of semi-finished products. Потенційні напрямки використання борошна з насіння чіа у складі фаршу напівфабрикатів обґрунтовано. Сучасний етап о Розвиток харчової промисловості передбачає розширення в ряд натуральних функціональних інгредієнтів, які покращують органолептику характеристики готової продукції та надають споживачам зі «здоровим» харчуванням. Це зумовлює використання нових інгредієнтів у м'ясопереробна промисловість для виробництва та розробки продуктів. Зв'язок між показниками емульгуючої здатності, стійкість до емульсії та ступінь гідратації борошна чіа було визначено експериментально. Було встановлено, що здатність до їжа чіа для поглинання та утримання молекул води та жиру в склад емульсії зменшувався пропорційно зменшенню в його концентрація в складі гідратованих зразків. The наявність неполярних бічних ланцюгів амінокислот, які зв'язуються до молекул жиру сприяє збільшенню показників емульгуючу здатність і стабільність емульсії при термічній обробці (70±2 °C) і після попереднього заморожування в середньому на 7–8,7 % і на 16–18,8 % відповідно. Аналіз ефективної в'язкості дисперсної системи чіа насіння борошна вказує на те, що в області більшої концентрації, на залежить в'язко-пружна і твердоподібна поведінка суспензії на динамічні зміни об'єму фази частинок. Нагрівання дослідних зразків до температури 70±2 °С в центру призводить до максимального збільшення в'язкості утворюється дисперсії. При вивченні дії процесів заморожування на властивості досліджуваних систем, кріопротекторні властивості для запропонованих добавок виявлено. Отримані дані свідчать про термостабілізацію запропонована добавка, здатність утворювати структуру мікрогелю в готового продукту, а також зберігають вологу при термічній обробці напівфабрикати
