Improving sucrose extraction technology when processing substandard raw materials
Authors: Kulneva N. G. , Posledova Y. I.
Published: December 2024

Long-term storage of large volumes of sugar beets, due to an increase in the production capacity of enterprises, leads to a decrease in the technological quality of raw materials. Unstable weather conditions cause freezing and subsequent thawing, which destroys beet tissue, increasing its accessibility to microorganisms. Processing of substandard raw materials is accompanied by the use of a whole range of bactericidal drugs at different stages of production, to which resistance of the accompanying microflora develops over time. To reduce the degree of infection of intermediate products at the production site, it is proposed to use a bactericidal preparation based on the sodium salt of dichloroisocyanuric acid (DCCN), which can be introduced into the extractant before feeding it into the diffusion apparatus. The influence of the quantity, concentration of the DCCN solution and the temperature of the extractant on the qualitative characteristics of diffusion and purified juices was experimentally established. A positive effect of DCN was revealed during the processing of beets contaminated with Leuconostoc mesenteroides. Using mathematical modeling methods, regression dependencies were obtained that reflect the relationship between process parameters and quality characteristics of juices. The optimal parameters for the use of DCCN in preparing the extractant for the diffusion process have been established: temperature 65 °C, concentration of the DCCN solution 0.05 %, its amount 15 %. This drug can also be used at the stages of storing sugar beets, processing beet chips before extraction, and disinfecting equipment.

Authors: Eremina O. Y. , Anokhin Y. V.
Published: December 2024

An analytical review of existing studies has shown that a significant number of athletes experience a deficiency of macro- and micronutrients. The most common deficiencies are vitamins D, C, B1, B2, folate, A, E, and minerals such as magnesium, calcium, and zinc. In recent years, the popularity of sports nutrition has been growing, which is associated with a growing interest in a healthy lifestyle and proper nutrition. The purpose of this study is to study the range of sports nutrition products and consumer preferences in the Oryol region. An analysis of the range of sports nutrition in stores in the city of Oryol showed that many stores have high rates of product range, but face a low coefficient of novelty and stability. This indicates the need to improve the range of new products and increase the stability of product offerings. A study of consumer preferences in the Oryol region shows that sports nutrition is mainly used to improve health (41%) and enhance immunity (38.5%). Most respondents do not attach much importance to the country of manufacture, preferring domestic brands only slightly more foreign. The most popular are vitamin and mineral complexes (43.6%) and proteins (41%), while meal replacements and pre-workout complexes are of less interest. When choosing products, the most important characteristics are taste, price, composition and reviews of other consumers. Brand and ease of use are of the least importance. More than 70% of respondents are ready to change the brand if there is a similar product with an improved composition. More than 50% trust the recommendations of other athletes, and 33.3% - the advice of a trainer or nutritionist. The presented data on the deficiency of vitamins and minerals, as well as the existing consumer demand, demonstrate the need to develop such types of sports nutrition as proteins, vitamin and mineral complexes, amino acids and thermogenetics.

Published: December 2024

One of the effective areas of research of real technological processes is the creation of virtual processes and its components. In the work, virtual computer models have been created that establish a connection between the mathematical model of the drying process and the simulated design of a two–section drum dryer equipped with an absorption water–ammonia heat pump. To simulate the drying process, a mathematical model based on differential equations of heat and mass transfer A.V. Lykov, algorithmic and software of the drying process were used and a single virtual system was created that allows simulating the drying process of cereals, oilseeds and legumes in a drum dryer in real time over a wide range of regime parameters. To conduct a computational experiment in one of the CAD systems, a three–dimensional visualization of a drum dryer was performed and a graphical shell of the LabVIEW environment was used with a set of all the tools necessary for data collection, analysis and presentation of the results obtained. 3D execution of the drum dryer in CAD (computer–aided design system) made it possible to simulate the real conditions of its operation, compare alternative options and select the best design solutions.

Published: December 2024

Quinoa (Chenopodium album) is an annual plant of the Amaranth family, rich in nutrients, used as a biologically active additive in food products. This unpretentious plant contains vitamins A, C, group B, minerals (calcium, iron, magnesium) and antioxidants (flavonoids and phenolic compounds) that support the immune system, improve digestion and have anti-inflammatory properties. Quinoa seeds contain more protein and complex carbohydrates than leaves, which makes them an excellent source of nutrition for maintaining muscle mass and normalizing the digestive tract. Sprouted quinoa seeds increase the bioavailability of nutrients and active enzymes, which helps improve digestion and antioxidant protection. Quinoa has found use in cooking — fresh leaves are added to salads and soups, and the seeds are ground into flour for baking. However, it is worth considering the high content of oxalates and nitrates in the plant, which requires moderation in use and thermal treatment.

The article is devoted to the development of technology and quality assessment of chilled nutrient-adapted minced meat semi-finished products (MPMP) using the protein-composite mixture (PCM) "Diso Nutrinum" with prolonged shelf life. The optimal addition of PCM to the recipe was found to be 7.5%. The addition of PCM in the amount of 7.5% contributes to the formation of the specified properties of MPMP due to the increased content of easily digestible proteins that form viscous colloidal solutions, which improves the functional and technological properties of the meat system, namely, moisture-holding capacity, fat-holding capacity and dimensional stability. The organoleptic properties of meat products (taste, consistency, appearance) are also improved. In terms of the sum of essential amino acids, the nutrient-adapted MPMP exceeded the values of both FAO/WHO and control objects. In the test samples, the content of essential amino acids is 2.5% higher than in the control. It has been proven that the non-thermal technology of cold plasma treatment can be used for food disinfection, since an increase in the plasma treatment time led to a decrease in the number of mesophilic-aerobic and anaerobic bacteria (MAAAB): with a 5-minute treatment with low-temperature plasma, MMAAB - 5.1∙104 CFU/g; with a 10-minute treatment - 4.4∙104 CFU/g; with a 15-minute treatment - 2.8∙104 CFU/g. At the same time, Listeria monocytogenes and Salmonella were not detected in any of the tested MRPF. The effectiveness of using the technology of high pressure processing (HPP) of meat food products has been scientifically substantiated, which reduces the indicators of QMAFAnM, suppresses and destroys the development of pathogenic microorganisms (coliform bacteria, Listeria monocytogenes, Salmonella, Proteus and others), which leads to an increase in the shelf life of minced meat semi-finished products.

Published: December 2024

Bacterial cellulose (BC) has significant potential for applications in the food industry due to its ability to stabilize food dispersion systems. In this work, the efficiency of BC biosynthesis on dairy industry waste was investigated, and these process parameters were studied: amount of substrate, titratable acidity, mass of synthesized cellulose. The physico-chemical properties and lipid binding capacity of the obtained gel films and dehydrated polysaccharide samples were determined. Bacterial cellulose was obtained under static conditions, in a liquid nutrient medium – whey. Lactose from whey was preliminarily hydrolysed with the enzyme preparation LACTA FREE to a glucose content of 1.93%. The mass of cellulose produced under static conditions by the symbiotic consortium Medusomyces gisevii was 3.84 g/l over 21 days at T=31°C. A correlation was noted between low amounts of glucose in the culture fluid on the 6th day of biosynthesis and a decrease in titratable acidity. The degree of conversion of glucose from fermented whey to the mass of produced bacterial cellulose was 22.6%. The maximum biosynthesis rate of 0.181 gL-1×day-1 (dry weight) was established on the 15th day of the process. The water retention capacity of the synthesized bacterial cellulose gel films was determined to be 82.35 ± 0.63 g/g. Lyophilized samples of bacterial cellulose were characterized by a higher water absorption capacity (22.44 g/g) compared to samples dehydrated at T=50°C (5.42 g/g). It was found that rehydrated samples of lyophilized cellulose had a 3.43 times higher ratio of free and bound moisture compared to dried BC samples. The bulk density of disaggregated cellulose was determined: lyophilized - 20 kg/m3, thermally dried - 170 kg/m3. The work provides a comparative analysis of the lipid binding capacity of BC and chitosan. Microbiological parameters of disaggregated bacterial cellulose were determined.

Published: December 2024

The possibility of using thermoplastic polymer films low density polyethylene and polyethylene terephthalate of domestic marks for the production of elixirs and soft molds intended for polymerization of dental composites used in orthodontics was established. The supramolecular structure and composition of the low-density polyethylene and polyethylene sheets of domestic brands, as well as their mechanical properties are different from the structure and properties of Shueu-Dental’s signature polymer materials. The difference in composition and degree of crystallinity of the sheets is determined by differential scanning calorimetry. The base of soft films for matrices is low density polyethylene with a crystallinity of 35±5%, and the base of hard films for the manufacture of elixers is an amorphous copolymer of ethylene terephthalate with a glassing temperature of 76-81 оС. The deformation properties of imported low density polyethylene are similar to the properties of domestic polymers of various brands. The deformation properties and crystallinity of imported polyethylene terephthalate are significantly different from those of domestic brands, which are similar in composition for the conformity of the polymer materials of Shueu-companyDental and domestically produced films produced modified heat treatment of domestic materials in the muffler furnace. By selecting the temperature and time of heat treatment of polyethylene terephthalate sheets, a material with reduced crystallinity is obtained without the content of «volatile» components. The suitability of a modified plastic terephthalate plate of domestic production for the manufacture of the aligner was tested by measuring its rigidity. Hardness was estimated by the size of the module Jung measured by stretching samples of original and modified materials at constant stretching speed. After the modified heat treatment, the degree of local pull and diversity of finished products (liners) made of low-density polyethylene and polyethylene terephthalate were investigated. Measured thickness at characteristic points and established a quantitative relationship between the thickness of the products and the degree of extraction of polymers used in orthodontics.

Authors: Shishanov M. V. , Cook C. G. , Gevorkyan E. L. , Botnev A. Y.
Published: December 2024

In this paper, a comprehensive comparative study of various geometrical characteristics of microcapillaries used for chemical reactions is carried out. Three main shapes of microcapillaries are considered: serpentine, fractal and lobular. The focus is on how microcapillary geometry affects key parameters of the reaction process, including reactant mixing efficiency, flow distribution, heat transfer, and reaction rate. Optimization of these parameters is critical to improve the performance of chemical processes at the microscale. COMSOL Multiphysics software was used for the simulations, which enabled the evaluation of hydrodynamic characteristics such as Reynolds number, mixing coefficients and temperature distribution profile. The study also includes calculations of criteria used to quantify the efficiency of reagent mixing. In addition to numerical modeling, experiments were conducted, the results of which were used to verify the obtained calculated data. This improved the accuracy and reliability of the conclusions. The results of the study show that the choice of microcapillary geometry has a significant influence on the hydrodynamic parameters of the flow and, consequently, on the overall efficiency of chemical reactions. For example, serpentine geometry may provide better mixing in the early stages of the reaction, whereas a brush-like shape may be optimal for long-term processes with high heat transfer rates. The conclusions of this work provide practical recommendations for the choice of microcapillary geometry depending on the specifics of the chemical reaction. Using the example of acetone self-condensation, a suitable geometry, lobular, was identified. The recommendations are aimed at increasing productivity, improving the quality of reaction products and reducing energy costs.

Published: December 2024

This study examines the physicomechanical and special properties of polymer films composed of hyaluronic acid (HA) and zinc oxide (ZnO) nanoparticles that can be used as transdermal patches. Transdermal patches are a popular method of medical and cosmetic procedures in various disciplines, not limited to cosmetology, gynecology, oncology, etc. They have advantages such as convenience and simplicity, the possibility of uniform drug delivery, and a wide range of possible applications. These advantages make transdermal patches an important tool for various areas of medicine. However, most biopolymers used as a polymer matrix do not meet the required physicomechanical properties when creating polymer films for medical purposes. That is why hyaluronic acid with ZnO nanoparticles as a filler was chosen as a polymer base. The work examines the effect of nanoparticle concentration on the physicomechanical and special properties of hyaluronic acid-based polymer films. It has been shown that using 5 wt.% ZnO nanoparticles results in the production of a polymer film based on hyaluronic acid, with optimal mechanical parameters for the balance between the relative elongation and strength of the resulting materials and compliance with the skin texture, which is of critical importance for increasing the long-term effectiveness of the use of the obtained polymer films as a base for creating transdermal patches

Currently, the processing of plant waste is a promising area of development in modern energy. There are many methods for recycling waste, but not all of them are economically feasible and environmentally friendly. One of the most common processing methods is fast ablative pyrolysis, designed for thermal processing of waste without access to oxygen. As a result of such processing, carbon residue and pyrolysis gas are formed. The amount of pyrolysis gases produced is 60 % or more of the mass of processed raw materials. In order for pyrolysis gases to become high-quality fuel, they must be subjected to a separation process that takes place in devices called a vapor condenser. When separating pyrolysis gases, it is better not to use conventional oil and gas condensers since the condensed pyrolysis gases have a high tar content, which causes faster wear of the device. For the installation for the production of pyrolysis fuel, a two-stage separation system is proposed, designed to separate pyrolysis gases into fractional components: pyrolysis distillate, non-condensable combustible gas and water. The article presents the design of a two-stage separation system. The principle of operation of a two-stage separation system is described, and a diagram of its structure is given. A method for calculating a two-stage separation system is presented, which makes it possible to determine the geometric parameters of scrubber and ejector type capacitors.

Published: December 2024

The human gut microbiota is a complex ecosystem consisting of trillions of microorganisms that symbiotically inhabit the human gut. Through the production of a number of metabolites, they perform many important metabolic functions that complement mammalian enzyme activity and play an essential role in digestion. Interindividual variability in the structure of the microbiota and hence the expression of its genes (microbiome) has been largely explained by diet. Nutrition affects the composition and function of the microbiota with short- and long-term effects. Although an extensive number of studies are available, the molecular mechanisms underlying these effects still remain incompletely understood. In this article, we summarized and concretized the available data on the effects of diet on the composition of the gut microbiota. Nutrition has short- and long-term effects on microbial colonies, accomplishing a profound impact on human health. In fact, diet-induced changes in the microbiota are progressively associated not only with human physiology but also with chronic diseases, including obesity, immune, metabolic and inflammatory bowel diseases. The relationship between human health, gut microbiota and nutrition represents one of the most promising and challenging topics for researchers. Indeed, the microbiota is a dynamic community undergoing changes according to dietary habits throughout the human lifespan and has a great metabolic potential to act on pharmacological targets and bioactive compounds.

Published: December 2024

Flour dishes have a simple production technology and are in demand among various groups of the population. A qualimetric model has been developed to predict the quality of flour dishes using vegetable milk substitutes. This product quality assessment tool provides an opportunity to measure the achieved result in numerical form, taking into account the characteristics and properties of the product, as well as to justify the results by the objectivity of the analyzed parameters, since they can be accurately quantified by objective instrumental research methods. The purpose of the research presented in this paper is to develop a model of qualimetric forecasting and assessment of food quality on the example of flour dishes using vegetable milk substitutes. The relevance of using plant-based milk substitutes in the recipe of flour dishes is determined by the following reasons: lactose intolerance among consumers, religious fasts and restrictions. Plant-based milk substitutes have a soft and delicate taste; they are easily absorbed by the body due to their natural composition and the absence of cholesterol. This makes them an ideal choice for people suffering from cardiovascular diseases. When forming the quality of flour dishes with vegetable milk substitutes, 9 indicators of consumer preferences and 7 measured indicators are taken into account. A comparison was also made with 3 analogues and target values of quantitatively measured indicators and units of measurement were selected. The results of this study will presumably be able to be used to assess the quality of flour dishes using vegetable analogues of milk. This will provide an opportunity to replenish the range of food products on the market of the Russian Federation, to ensure its quality, competitiveness and safety for consumers.

Published: December 2024

Currently, scientists are developing in the field of improving the composition and quality of sour cream and sour cream products. The main part of these products has a functional orientation due to the inclusion of additional ingredients in the composition. The use of food additives containing iodine in the technology of sour cream products is of interest. Seaweed (kelp) is the most iodine-rich. In addition, kelp is rich in vitamins A, B, C, E, D and antioxidants, iron, magnesium, bromine, etc. Seaweed contains enterosorbents - substances capable of removing toxins from the human body; fucoxanthin – accelerates metabolism, dietary fiber. The product obtained at the Department of Technology of Animal Products of VGUIT contains the following components: milk cream, sour cream starter, kelp powder. In order to establish the optimal dosage of the vegetable component, kelp powder was introduced at the fermentation stage of the mixture in an amount from 0.5 to 2.0%. The optimal dosage of 1.0-1.5% has been determined. The addition of seaweed powder above the indicated dosage led to a deterioration in the organoleptic characteristics of the product. The sour cream product was obtained using traditional technology. A special feature was the operations of preparation and application of starter culture and kelp powder. It was found that the degree of grinding of dried seaweed powder has a significant effect on the quality of the sour cream product. The sour cream product had a sour-milk taste and smell, had a white with a cream tint with slight inclusions of kelp particles. During the entire storage period, organoleptic, physico-chemical and microbiological parameters were determined. The viscosity of the test sample increased by 32% compared to the control one was determined. The consistency of the sour cream product is stable during storage. According to the research results, the sour cream product has a strong connection with the clot. The addition of kelp powder makes it possible to obtain a sour cream product with an enriched vitamin and mineral composition.

Published: December 2024

The main disadvantage of most fondant candies is high sugar content and calorie content, low content of useful essential nutrients, rapid drying and staling during storage. It is relevant to use jerusalem artichoke pulp powder instead of sugar, which contains a significant amount of dietary fiber and minerals with high moisture-retaining properties. The introduction of jerusalem artichoke pulp powder in an amount from 5 to 9% contributes to: acceleration of the structure formation of the fondant mass due to the intensification of the sucrose crystallization process; to change the rheological properties of the fondant, namely, to increase its viscosity and plastic strength; to increase the dispersion of the fondant, while the proportion of sucrose crystals less than 20 microns in size in the fondant increases by 9–16%; to reduce the drying process of sweets during storage; to reduce sugar content, calorie content and increase nutritional value by increasing the content of dietary fibers and mineral substances. When using jerusalem artichoke pulp powder in an amount of 9% instead of sugar, it allowed to obtain functional fondant candies in terms of the content of soluble dietary fiber (31.5% of the daily requirement), which have a prebiotic effect. Compared with the control sample, the carbohydrate content in the experimental sample decreased by 8.1%, the calorie content decreased by 27 kcal, the potassium content increased by 42.9 times, calcium by 3.5 times, magnesium by 4 times, phosphorus by 12 times, iron by 8 times. Therefore, the use of this concentrator is advisable and promising from the point of view of improving the quality and increasing the nutritional value of the product, the developed technology of fondant candies using jerusalem artichoke pulp powder can be recommended for implementation in confectionery enterprises.

The problem of using chemical plant protection products in agriculture is exacerbated by their negative impact on the environment and the resulting products. Intensive use of fungicides, herbicides, insecticides against diseases, weeds and pests in agricultural production leads to a decrease in soil fertility and product quality, a reduction in agronomically valuable microorganisms. The relevance of biological plant protection increases. To restore the homeostasis of the soil microbial community, to obtain high and environmentally safe products, it is necessary to use biological methods of combating sugar beet diseases. For this purpose, microbiological biopreparations are being developed based on strains of microbes that are antagonists of phytopathogens, one of them is Bacillus subtilis. The results of field studies on the effect of introducing a suspension of native strains of Bacillus subtilis on the intensity of development and prevalence of the main diseases of the leaf apparatus of sugar beet are presented. According to the research results, suspensions of Bacillus subtilius 20 and 17(8) strains are effective in combating diseases such as: alternaria, cercospora, phomosis, viral jaundice, powdery mildew. Treatment of the leaf apparatus with antagonist microorganisms Bacillus subtilis 20 and Bacillus subtilis 17/8 contributed to an increase in the yield of sugar beet root crops by 5.2-10.7 t/ha. This is due to the fact that the introducers successfully populated the phylloplane of developing plants and the soil, optimized the structure of the microbial community, and contributed to a decrease in the disease of the leaf apparatus of sugar beet.

Published: December 2024

The work provides data on the technology for producing distillates during the joint processing of fruit and grain raw materials, using batch devices and continuous distillation units. Factors constraining the production of fruit distillates in the Russian Federation are considered. A method for processing fruit raw materials using existing equipment of distilleries is proposed. Using a laboratory batch distillation unit, the technological process for the industrial production of distillates using continuous distillation units was simulated. The features of the production of distillates from grain and fruit raw materials in a laboratory batch distillation unit using the double distillation method are considered. Based on the results of the studies, it was established that there is a technological possibility of using continuous-action devices, implemented on the basis of distillation units of distilleries, to obtain distillates with original organoleptic characteristics based on grain and fruit raw materials. Samples of unaged distillate with organoleptic characteristics inherent in the original raw material were obtained. A hardware and technological scheme for a continuous operation installation for the production of distillates from fermented grain and fruit raw materials has been developed. It has been revealed that the process of distillation of grain-fruit mash on devices operating under atmospheric pressure may be accompanied by the formation of carbon deposits of undissolved substances on the structural elements of the distillation apparatus. In the process of distilling mash from grain and fruit raw materials, the methyl alcohol content in the product can reach 0.2%, which must be taken into account when planning production. Recommendations have been developed for the implementation of the technological process for the production of distillates from grain and fruit raw materials on the technological equipment of alcohol factories.

One of the main factors affecting the quality of bread are microbiological and biochemical processes occurring in dough semifinished products as a result of yeast activity. These processes can be controlled by regulating the biotechnological characteristics of yeast, which allows to intensify technological operations of baking production. Baking yeast should have high enzymatic activity, the ability to release carbon dioxide in anaerobic conditions and quickly adapt to changes in the composition of the nutrient medium. These properties of yeast can be improved by pre-activation in nutrient media containing components that intensify the synthesis of fermentation enzymes in yeast cells. The aim of the work was to study the effect of pre-activation of pressed baker's yeast Saccharomyces cerevisiae in nutrient media with food complex additive on their biotechnological characteristics: lifting force and enzymatic activity (zymase, maltase). Yeast lifting force was determined by accelerated method. Zymase and maltase activities were determined by measuring the time for which 10 cm3 of carbon dioxide is released during digestion of glucose and maltose solutions by yeast, respectively. The novelty of the work consists in the establishment of parameters of preliminary activation of baker's yeast Saccharomyces serevisiae with the use of food complex additive. It is shown that the optimal duration of yeast pre-activation is 20 min. Pre-activation of pressed yeast contributed to the increase of their biotechnological characteristics: yeast lifting force increased by 46.9 %, zymase activity - by 37.7 %, maltase activity - by 13.4 %. The obtained results indicate the promising application of yeast pre-activation in nutrient medium with food complex additive in the production of bakery products

Aragonite neomorphism via intrafabric dissolution and calcite precipitation, not thin films
Authors: Saller Arthur
Published: December 2024

Since the 1970's, aragonite neomorphism (conversion of aragonite to calcite with partial retention of original internal structure) has been attributed to thin diagenetic films, often in meteoric water. Pleistocene material from Enewetak, the Bahamas and eastern Yucatan show the transition from aragonite to calcite "in progress". Original aragonitic material includes coral, Halimeda, molluscs (especially gastropods) and ooids. In all three areas, aragonite commonly shows partial intrafabric dissolution. In many cases, calcite crystals grew over that highly microporous aragonite to create calcite with partial retention of the original depositional fabric, creating neomorphosed (calcitized) aragonite. Geochemical data support this scenario. Carbon and oxygen isotopic compositions of the neomorphic calcites are similar to sparry meteoric calcite cements indicating crystals precipitated from similar waters as the cements. Stable carbon isotopes and Mg concentrations in neomorphic calcites are different from their aragonitic precursors and are not consistent with the thin-film model, which assumes a semi-closed system. Approximately 40 of the 95 Pleistocene Enewetak samples have aragonite with intrafabric dissolution adjacent to calcitized (neomorphic) aragonite. Neomorphosed (calcitized) aragonite was not observed immediately adjacent to unaltered aragonite (i.e., separated by what would have been a thin film) in any Enewetak samples. This supports aragonite neomorphism by a two-stage process (intrafabric dissolution followed by calcite precipitation) rather than by thin films. Variations in concentration of inclusions in neomorphosed aragonite are similar to variations of relict material in aragonite with partial intrafabric dissolution and span a continuum from abundant aragonitic inclusions in neomorphic spar to inclusion-free calcite cement.
