Full textAbstract:
This study aimed to determine the effect of technological parameters of the production of horse meat minces with the addition of protein-oil emulsion from chicken combs on the functional, technological and physicochemical indicators. Chicken combs were pre-treated with bacterial concentrate to improve their properties. Experimental approach: The ultimate shear stress and technological indicators – water holding capacity and oil holding capacity – were determined to set the optimal time for cutting raw materials. Physicochemical analyses of the meat minces were conducted. Results and conclusions: The research results have shown that the cutting time significantly affects the meat minces' rheological, functional and technological indicators. The optimum mixing time for meat minces is 6 min. Adding a protein-oil emulsion from biotechnologically processed chicken combs, cottonseed oil, and water into the minced horse meat does not significantly affect the nutritional value. Adding 15 – 20% protein-oil emulsion (POE) is recommended to get minced meat with optimal rheological parameters.

Full textAbstract:
Compositions of artificial soil mixtures, including sand, clay, defecation mud, waste from wet magnetic separation and plant residues in different proportions have been developed. The components were preliminarily comminuted by an auger-drill in order to obtain a homogeneous composition with subsequent granulation, stored in natural conditions in the autumn-winter period, followed by filling in experimental vessels. No any phytotoxic effect for the initial components and for all analyzed samples of the obtained artificial soil mixtures was detected. The chemical composition and some physicochemical properties of artificial soil mixtures, such as density, deposit of moisture and humus content, were determined. It was shown that the samples of the obtained soil mixtures are close to the control (dark gray forest soil of the Belgorod region) and can be recommended for further use in creating cultural landscapes as a substitute for natural soil. The developed type of artificial soil mixtures is suitable for the cultivation of bulbous crops; moreover, a large increase in yield in comparison with the control for some compositions was found. Artificially created soil mixtures reduce the harmful effect on the environment by eliminating the storage of industrial waste such as iron ore and food, plant residues used in the composition of the artificial soil mixture. Artificial soil mixture can be used for remediation of technologically disrupted areas, which will allow restoring disturbed lands and reducing man-caused impact on solid waste landfills. The addition of industrial waste allows them to be re-involved in the technological cycle, which contributes to the development of low-waste and waste-free technologies. The results obtained indicate the possibility of using the studied soil mixtures for cultivation of the decorative bulbous plants. To recommend the developed compositions for the use in agriculture, it is necessary to assess the possibility of impurity translocation from soil samples into cultivated crops.

Full textAbstract:
The management practices used by farmers in cassava crops and the relationship with the sensory quality and physicochemical characteristics of cassava roots are still incipient. The objective of this work was to evaluate the productivity, sensory quality and physicochemical properties of cassava roots at harvest times and technological management levels. The study was conducted in Santa Maria, Rio Grande do Sul, Brazil, and the management practices employed in the field experiment corresponded to low, medium and high technological levels used by farmers in southern Brazil. The cultivar “Vassourinha” was used and the roots were harvested in the sixth, the seventh, and the eighth month after planting. The productivity, the physicochemical composition of the roots (dry matter, protein, lipid, ash, total fiber, resistant starch, and total starch) were determined, and the sensory analysis of the roots was performed. Technological levels did not influence the root productivity and it increased with the delay in the harvest season. There was an increase in protein at the high technological level and the highest content of starch was found in the roots harvested in the seventh month. Sensory acceptance of the roots showed greater acceptability in the sixth and seventh months after planting, with roots of a high technological level being preferred. Based on the results, the influence of management practices in the nutritional composition of the roots represents an important aspect for assessing the potential of the roots to be consumed or used in industrial processes.

Full textAbstract:
This study examined the qualitative indicators and physicochemical characteristics of cottonseed, soybean, and linseed oils, as well as their processed products, with the aim of developing new types of shortening fats. The research established that to achieve the required quality and physicochemical characteristics in shortenings from vegetable oils, the following parameters must be observed: phospholipid content (0.97-2.35%), tocopherol content (0.57-1.69 mg/kg), acidity (0.17-0.35 mg·KOH 1 g), and peroxide number (3.1-4.6 mol/kg). Based on these findings, new formulations for shortening fats were proposed using hydrogenated cottonseed (10-90%) and soybean (40-60%) oils, as well as linseed oil (5- 10%). The effective and rational use of local fat sources resulted in improved quality and a minimum content of trans acids, ensuring the food safety of the shortenings. The study also established the role and significance of the quantitative content (15–95%) of hydrogenated fatty acids (Tm=30.7-31.4°C, Tw=180-200 g/cm) and trans-isomerized fatty acids (3.1-4.7%) in the formation of quality indicators and physical and chemical characteristics of the developed shortenings.

Full textAbstract:
The current intensive industrialization has changed the food preferences of consumers. As a result, there is a growing demand for high-grade high-nutritional meat and dairy products, which, in its turn, triggered an increase in the demand for grain crops and led to higher animal feed prices. All these affected the price and quality of the finished product, since farms are trying to stay profitable. As a consequence, the high cost of animal proteins make producers look for other sources of protein with similar qualities. Common oat (Avena sativa L.) remains the most cultivated species. Oats are a source of high-quality protein with an optimal amino acid balance. The paper features a oat protein technology (Avena sativa). The research defined the parameters of the protein extraction process. For acid and alkaline methods, the following optimum parameters were revealed: temperature – 40 ± 2°C, hydraulic module – 1:10, time – 90 minutes, active acidity of the acid extraction – 2.0 units, active acidity of alkaline extraction
 – 9.0 units. The authors managed to obtain protein substances with the molecular weight > 50 kDa. The optimal parameters of ultrafiltration of the protein extract were as follows: pore diameter = 100 kDa at pH 8.0 and 0.5 MPa. The ultrafiltration conducted under these conditions showed that the content of high molecular fractions (globulins and albumins) increased from 39.12% to 55.15% for the extract obtained by alkaline method, whereas the content of low molecular weight fractions (prolamins and glutelins) decreased from 60.88% to 44.85%. Ultrafiltration of protein extracts obtained by alkaline and acidic methods made it possible to concentrate protein fractions with a molecular weight ≥ 50 kDa. When a 10% aqueous solution of succinic acid was used as a precipitator, the protein precipitation degree equaled 89.3%. The paper introduces a new oat protein purification method. The optimal multiplicity of purification by RP-HPLC was 4 purification cycles. For the alkaline extract, the total content of high molecular weight fractions (50.0–120.0 kDa) was 72.7% and the total content of low molecular weight fractions (15.0–49.0 kDa) was 27.3%. For the acid extract, the total content of high molecular weight fractions was 72.9%, while the content of low molecular weight fractions was 27.1%. Oat proteins obtained by alkaline and acid extraction demonstrated a high foaming ability (148–177%) at pH = 6.0–9.0, as well as a good fat and water retention capacity. The oat proteins were found to have a high content of protein and essential amino acids similar to animal proteins. A comparative analysis showed that oat protein can act as an alternative substitute for animal proteins.

Full textAbstract:
Fermentation is an economical method for obtaining protein hydrolysates. The purpose of the scientific research was to perform a comprehensive analysis of the physicochemical, technological, and functional properties of protein hydrolysates obtained by microbial fermentation. The research results showed that hydrolysates fermented with propionic acid bacteria and bifidobacteria have better physicochemical and technological indicators compared to the control sample. Significant increases in water-holding and fat-holding capacities (by 1.8–2.1 times and 1.5–2.5 times, respectively), as well as fat-emulsifying ability (by 12.8–29.8%) in experimental samples were found. Hydrolysates obtained by fermentation effectively inhibit the growth of Escherichia coli and Staphylococcus aureus. The thermal analysis showed a sufficiently high-thermal stability of the obtained protein hydrolysates. In hydrolysates fermented by bacterial culture, the removal of physico-mechanical and osmotically bound moisture occurred at temperatures of 110 °C and 115 °C, respectively, and in whey protein hydrolysate at a temperature of 100 °C. The release of chemically bound moisture was observed at a temperature of 170 °C for fermented hydrolysates and at 155 °C for the control sample. The results proved that fermented protein products are characterized by high functional properties, antioxidant and antimicrobial activity, and can be used as natural food additives and preservatives.

Full textAbstract:
Quince (Cydonia oblonga Miller) is a plant that is commonly cultivated around the world, known for centuries for its valuable nutritional and healing properties. Although quince fruit are extremely aromatic, due to their high hardness and sour, astringent, and bitter taste, they are not suitable for direct consumption in an unprocessed form. However, they are an important raw material in fruit processing, e.g., in the production of jams, jellies, and juices. Quince fruits fall under the category of temperate fruits, so their shelf life can be predicted. Considering that technological processing affects not only the organoleptic properties and shelf life but also the functional properties of fruits, the aim of this research was to determine the impact of various types of technological treatments on the physicochemical and bioactive properties of quince fruit. In fresh, boiled, and fried fruits and in freshly squeezed quince fruit juice, basic parameters, such as the content of dry matter, moisture, soluble solids (°Brix), pH, total acidity, water activity, and color parameters (L*a*b*) were determined. The content of key bioactive ingredients, i.e., tannins, carotenoids, flavonoids, phenolic acids, and total polyphenols, was also determined, as well as the antioxidant activity of raw and technologically processed (cooked, fried, and squeezed) quince fruits. The conducted research showed that fresh quince fruit and processed quince products can be a very good source of bioactive ingredients in the diet, such as tannins (3.64 ± 0.06 mg/100 g in fresh fruit; from 2.22 ± 0.02 mg/100 g to 5.59 ± 0.15 g/100 g in products), carotenoids (44.98 ± 0.18 mg/100 g in fresh fruit; from 141.88 ± 0.62 mg/100 g to 166.12 ± 0.62 mg/100 g in products), and polyphenolic compounds (246.98 ± 6.76 mg GAE/100 g in fresh fruit; from 364.53 ± 3.76 mg/100 g to 674.21 ± 4.49 mg/100 g in products). Quince fruit and quince products are also characterized by high antioxidant properties (452.41 ± 6.50 µM TEAC/100 g in fresh fruit; 520.78 ± 8.56 µM TEAC/100 g to 916.16 ± 6.55 µM TEAC/100 g in products). The choice of appropriate technological processing for the quince fruit may allow producers to obtain high-quality fruit preserves and act a starting point for the development of functional products with the addition of quince fruit in its various forms, with high health-promoting values and a wide range of applications in both the food and pharmaceutical industries.

Full textAbstract:
Pectin, a plant-derived polysaccharide, possesses immense technological and biological application value. Several variables influence pectin’s physicochemical aspects, resulting in different fermentations, interactions with receptors, and other functional properties. Some of those variables are molecular weight, degree of methylation and blockiness, and monosaccharide composition. Cancer cell cytotoxicity, important fermentation-related byproducts, immunomodulation, and technological application were found in cell culture, animal models, and preclinical and clinical assessments. One of the greater extents of recent pectin technological usage involves nanoencapsulation methods for many different compounds, ranging from chemotherapy and immunotherapy to natural extracts from fruits and other sources. Structural modification (modified pectin) is also utilized to enhance the use of dietary fiber. Although pectin is already recognized as a component of significant importance, there is still a need for a comprehensive review that delves into its intricate relationships with biological effects, which depend on the source and structure of pectin. This review covers all levels of clinical research, including cell culture, animal studies, and clinical trials, to understand how the plant source and pectin structures influence the biological effects in humans and some technological applications of pectin regarding human health.

Full textAbstract:
As the global population continues to grow, there is an increasing need to explore alternative nutrition sources that are sustainable, affordable, and environmentally friendly. Lentils, from leguminous crops, are a promising option because of their high protein content and numerous health benefits. The Food and Agriculture Organization (FAO) has recommended the development of composite flours as an effective way to incorporate local, nutritious grains into food products. Composite flours are mixtures of different flours, often combining traditional grains with healthier alternatives like lentils. These flours are cost-effective, quick to produce, and improve food quality. While many studies explore lentil-based composite flours, few provide comprehensive reviews of their physicochemical and technological properties. Understanding these properties—such as water absorption, binding capacity, and effects on food texture and flavor—is crucial for predicting their quality and potential applications in various food systems. By reviewing the techno-functional and physicochemical characteristics of lentil-based composite flours, this study aims to fill that gap and provide insights that could promote the commercialization of food products made with these flours. Ultimately, this could help make healthier, sustainable food options more accessible to a larger population.

One of the sources of sodium are meat products. Increased consumption of meat products and sodium intake leads to serious health problems. The task of reducing the dosage of sodium chloride in minced meat needs to be addressed. The partial replacement of table salt with sea salt will reduce the sodium concentration in products to 20%. It is established that this modification increases the moisture-binding properties of minced meat and lowers the dosage of salt in the mass of raw meat, which will reduce the level of harm to the body due to excessive consumption of sausages. It is proposed to introduce a bacterial preparation based on the strain Staphylococcus carnosus, which will reduce the amount of sodium nitrite in the finished products. Technology has been developed to regulate the composition of microelements in meat products by enriching them with a kelp extract. It was found that changes in the composition of minced meat can adversely affect the taste and physicochemical properties of the product, which is confirmed by expert studies. As a result of laboratory studies, it was found that a partial change of salt in the sea helps to improve the stability and physicochemical quality of minced meat (active acidity, water activity, moisture retention, and shear stress). According to the research results, the recipe of sausages recommended for implementation at the enterprises of the meat processing industry of Ukraine has been developed.

The article explores the possibility of using inulin and lamb in meat loaf technology. Physicochemical and organoleptic characteristics of meat loaf were studied, and the positive effect of inulin on the finished product was proved. Inulin is a plant-derived carbohydrate that has unique nutritional and technological benefits. Inulin reduces the risk of colon cancer, atherosclerosis, osteoporosis, diabetes and obesity, maintains low levels of triglycerides and cholesterol in the blood serum, stimulates the immune system, improves the water-holding ability and stability of the emulsion, and also changes the texture and viscosity of food products. As a functional food ingredient, it can be used in various foods as a substitute for fat. The inclusion of inulin in meat products seems to be useful in the production of low-fat products with the desired texture and sensory properties. Currently, the use of inulin in the technology of preparing meat loaf based on lamb is practically not studied. When developing and optimizing the formulations of meat products, an important point is the qualitative composition of food ingredients, which provides physiological needs of the human body for energy and necessary nutrients, taking into account age and existing medical and biological recommendations. Basing on the studies, a formulation and a technological scheme for the production of a meat product were developed. Thus, there was obtained a functional product of good quality, with increased nutritional and biological value, that meets all the requirements of the consumer.

Full textAbstract:
The study’s relevance lies in obtaining valuable information about Adalbert Erdelyi’s painting, which enhances the understanding of his artwork, supports efforts at accurate attribution, and enriches the study of art history. The purpose of this study was to characterise artist’s painting materials and technique of the post-Budapest period and introduce obtained results into scientific circulation. The research methodology was based on an integrated general scientific approach that combines theoretical and empirical methods, including art-critic and comparative analyses as well as optical and physicochemical methods. X-ray fluorescence analysis and Fourier-transform infrared spectroscopy were used to determine the artist’s pigment palette. Until now, only a few works of Adalbert Erdelyi’s early creative stage have been known and introduced into scientific circulation. A comprehensive study of Adalbert Erdelyi’s still life was carried out. The stylistic and technological features of the painting that were inherent in the post-Budapest period were established. It has been shown that cardboard made from a mixture of rag fibers and wood pulp was used as the painting support. The type of cardboard gluing and fillers were determined. The still life was painted wet-on-wet on the unprimed support without applying underdrawings. The analysis of the organic binder has shown that the painting was executed in the oil painting technique. Pure lead white was identified in white paints. Lead white with an admixture of zinc white, a mixture of lead white and zinc white, chrome yellow (lead chromate), vermillion, alizarin crimson, ocher, Emerald green (copper acetoarsenite), and Prussian blue were found in the paint layer. The identified pigments and a comparative analysis of oil polymerisation in lead white paint allowed us to confirm that the painting was created in 1918. It is shown that the artistic and style characteristics of the painting correspond to Adalbert Erdelyi’s post-Budapest period. Thus, “Still Life with Glasses on a Tray” can be considered the first known image of glasses with water in the artist’s creative heritage. The results of carried out research are an important informative source in the analysis of the artist’s early works and can be useful for art historians a nd curators of museum collections

Background. In recent years, dietary supplements have become the subject of interest among con sumers, food producers and the pharmaceutical industry. Dietary supplements are not medicinal products and are not considered as such. However, the majority of society in many countries treats dietary supple ments as equal to medicinal products. The article draws attention to innovative dietary supplements con taining many ingredients from exotic plants, which have not been used in supplements to such an extent so far. The aim of this study was to determine the physicochemical properties of multi-ingredient Purella Super Mix dietary supplements. These supplements are produced by Purella Food, and the series includes five products with various advertised effects on the human body. Purella Super Mix products were charac terized in terms of their composition and the resulting importance for human health. A number of physico chemical analyzes of Purella Super Mix were carried out, which have not been published to this extent before. Water content, water activity, bulk density and the angle of repose and cone angle were measured, as well as the Hausner ratio and the Carr index were determined. These properties deliver important in formation both for the technological process and for subsequent stages of the product life cycle. Results and conclusions. The results of the research on the physicochemical properties of innovative multi-ingredient dietary supplements can be used to predict the durability of these products and to design the packaging that takes into account the behavior of supplements during storage. The results obtained may also constitute the basis for further research on improving the composition and properties of multiingredient dietary supplements.

The concept of improving drug biopharmaceutical properties by proper selection of delivery system should begin with a rational choice of relevant dosage form, followed by the precise assessment of physicochemical compatibility between the drug delivery system (DDS) and the active pharmaceutical ingredient (API). Afterwards, according to laboratory availabilities, an efficient production method should be selected and, if possible, to take into account the opportunity for lab-upscale and prevailed industry research needs. Amid the vast diversity of nanostructured drug delivery carriers, lipid nanoparticles (LNs) stand out with their undeniable advantages like exceptive biocompatibility and multiplicity, and their importance as “green” derivatives for biochemical processes. Their distinctive structural properties also allow adequate protection of loaded APIs against chemical degradation in an aggressive biological environment and provide excellent resiliency in modifying drug release profiles. This review highlights different findings reported by the researchers worldwide over the years and focuses on the various production strategies and techniques for the preparation of LNs.

The current research was completed at the Indian Council of Agricultural Research - Central Institute of Fisheries Technology (ICAR-CIFT), Cochin, Kerala, India from August 2021 to August 2022 as a modified thermal extraction protocol for deriving gelatin from processing waste of skipjack tuna (Katsuwonus pelamis) skin. The study evaluated the effect of chemical composition and molecular weight contributing to the techno-functional attributes of the resulting gelatin. In the present study, we followed warm water-coupled NaCl pre-treatment to reduce the lipid content of the extracted gelatin. The extracted gelatin was characterized for Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The amount of gelatin extracted from the fish skin was 9.30±0.22%. The protein pattern of extracted gelatin on SDS-PAGE was identical to commercial grade gelatin, which implies the purity of extracted gelatin is comparable to that of commercial one. The physicochemical and functional properties were evaluated and pose remarkable techno-functional properties. Therefore, fish processing skin waste of skipjack tuna could be effectively exploited for the preparation of commercial gelatin. The extraction protocol remains environment friendly and this approach remains optimal for food technological applications. The effective exploration contributed to nutritional benefits, technological, functional, and biological functionalities for a large fraction of applications in the area of food technology, nutraceuticals, pharmaceutics, and numerous others as a future line of research.

Full textAbstract:
Camu-camu is an exotic fruit, known for having high concentrations of vitamin C and bioactive compounds. In order to diversify the consumption of this fruit, this study developed milk ice cream formulations and evaluated the effect of the addition of different concentrations of camu-camu pulp (20 to 26%), sugar (12 to 14%) and defatted dry extract (DDE) (12 to 16%) through a mixture design. Ice creams were evaluated by analyses of overrun, density, melting time, ratio, and cost. Three formulations were defined based on maximum melting time and ratio and minimum cost. The ice creams formulations defined by the experimental design consisted of the following proportions of pulp, sugar and DDE (%): 26:12:12, 20:14:16 and 24:14:12. These formulations were evaluated in relation to their physicochemical and technological characteristics, antioxidant and reducing capacity and sensory acceptance. The results showed that all formulations had high concentrations of antioxidant compounds and vitamin C and the formulation with the addition of camu-camu pulp lower than 24% had greater sensory acceptance. Therefore, it is concluded that the addition of camu-camu pulp in milk ice cream is interesting from a nutritional point of view, as it can increase the content of nutrients and minerals in the final blend.

This research study investigates the physicochemical properties of clay minerals extracted from the Keles, Kyzylorda, and Tagan mineral deposits in Kazakhstan. Modern analytical methods, such as high-precision X-ray fluorescence spectrometry (XRF) and X-ray diffraction (XRD), were employed to determine the chemical and mineralogical composition of the minerals. These methods allowed for high-accuracy identification of the elemental composition, crystal structure characteristics, and phase composition of the clay minerals. The main section of the study thoroughly explores the physical properties, chemical stability, and technological characteristics of the clay minerals. Special attention was given to the potential applications of montmorillonite and bentonite clay solutions in drilling operations, liquid purification systems, and other technological processes. The hydrodynamic dispersion filtrates' optical density, electrokinetic properties, cation exchange capacity, electrical conductivity, and ecological application potential were experimentally determined. The study concluded that the physicochemical properties of the examined clay solutions make them suitable for use in drilling operations. The findings reveal new prospects for the application of clay minerals in Kazakhstan’s oil and gas industry, the production of construction materials, and the resolution of environmental issues. The regularities and dependencies identified during the research will form the theoretical basis for developing innovative technologies for processing clay minerals and improving their industrial application efficiency. Moreover, the data obtained from the study offer the possibility of intentionally modifying the properties of clay minerals and producing new functional materials based on them.

The paper presents the results of a critical analysis of existing technologies for processing lead-zinc ores and industrial products; the relevance of the research lies in the development of methods aimed at additional extraction of zinc and lead in conditions of a rapid decrease in the content of lead and zinc in ores. The paper presents research on the thermodynamic justification of sulfiding roasting, the results of the development of technology for intensifying the process of processing poor, difficult-to-process complex lead-zinc ores and middlings through preliminary thermal activation by sulfiding roasting in a fluidized bed furnace. The mechanism of sulfidation of oxylated lead compounds has been established according to the scheme: PbO → PbO·PbSO4 → PbSO4 → PbS. The results of the physicochemical study of roasting products, as well as the results of magnetic enrichment of cinders, are presented. The results of magnetic separation of cinders after heat treatment of industrial products show that it is possible to separate up to 70% of iron in the form of pyrrhotite into a magnetic product, while the pyrrhotite content in the magnetic product is up to 98.2%. The paper presents a new technological scheme for processing lead-zinc industrial products from enrichment to obtain pyrrhotites with predicted properties.
