"Зеленые" технологии с применением двуокиси углерода в пищевой промышленности
Статья научная
Опыт развития социальных государств свидетельствует о наличии прямой зависимости между экономическим, социальным и экологическим развитием и инновационной направленностью проводимой промышленной политики. Иными словами, главной целью промышленной политики должно стать обеспечение высокого уровня качества жизни, социальных гарантий и экологической безопасности, достигаемое путем инновационного развития определенного комплекса отраслей. Одной из таких отраслей является пищевая промышленность. Ее главная цель на современном этапе – обеспечение эколого-социального типа экономического роста. Инновации в пищевой промышленности, приносящие экономический, экологический и социальный эффекты должны стать приоритетными при формировании инновационно-промышленной политики. Таких инноваций в пищевой промышленности России разработано достаточно много, однако инструментов для стимулирования их внедрения явно не хватает. Рассматривая вопросы инновации в пищевой промышленности необходимо учитывать, что в настоящее время главное не только цена-качество, но экологическое и социальное воздействия на потребителей...

Active packaging material based on biodegradable polymer
Статья научная
Modern trends in processing, storage and packaging of food products are aimed at preserving the native properties of raw materials, ensuring hygienic safety, modern design and properties of the packaging material intended for the consumer. Pasteurized milk production includes following stages - normalization, heat treatment, packing and packaging, at which it is important to preserve the quality of the finished dairy product, that is why polymeric containers are used for most dairy products. The research was aimed to develop polymeric packaging for milk, characterized by additional material functions and capable of biological degradation after use. Polylactide with the introduction of an inert filler was chosen as a promising packaging material. The authors have produced electret films based on polylactide with the introduction of 2, 4 and 6% talc. Polarization of the samples was carried out by means of corona discharge on a unit with a square needle electrode with an area of 49 cm2. Increasing the talc content in the composition of samples contributed to the reduction of mechanical characteristics of materials. It was found that the introduction of talc into polylactide increases the electret properties of the material, which is based on the occurrence of additional traps of injected charge carriers. The developed polymeric material was tested using cow's milk industrially pasteurized at 74-76°C. Studies were conducted to evaluate the effect of electret polylactide film on acidity and microflora composition of pasteurized milk during storage at 37°C for 48 hours. In the presence of active packaging material, the formation of a dense milk clot and an increase in the acidity of the product were observed during the milk fermentation.

Application of drying acceleration to study the forms of moisture bond in currant fruits
Статья научная
The article discusses issues related to the study of the forms of connection of moisture removed during the drying process in black currant fruits. A study was carried out to determine the quantitative moisture content of various forms of communication by two methods and a comparative analysis was carried out. It is shown that the existing methods for studying the forms of moisture-material bonding have significant drawbacks and generally give a qualitative assessment of the state of moisture in the material or are very laborious and require long-term laboratory studies. The efficiency of the approach to determining the forms of moisture connection in black currant fruits is shown on the basis of graphical-analytical analysis of the drying kinetics, which allows qualitatively and quantitatively assessing the state of moisture in the fruits. With the help of a graphical editor, the curves of the drying kinetics of black currant fruits were processed and the dependences of the quantity called "drying acceleration" characterizing the rapidity of the change in the drying rate of currant fruits on the moisture content of the product were obtained. The analysis of the obtained curves is carried out, indicating the presence of extrema and points of inflection to the corresponding critical moisture content, as well as the presence of areas with a slowdown or acceleration of the drying rate change, allowing to establish the intervals of moisture removal with different binding energies. The approach under consideration makes it possible to give a quantitative and qualitative assessment of the physical state of moisture not only in currant fruits, but also in other food products, as well as reduce the time for analysis and improve the accuracy of the results.

Biopolymers and its application as electroactive polymers
Статья научная
Smart materials are a group of materials that exhibit the ability to change their composition or structure, their electrical and/or mechanical properties, or even their functions in response to an external stimulus such as heat, light, electricity, pressure, etc. Some of the advantages of these materials are: lightweight, flexibility, low cost of production, high energy density, fast response and compact size. One of the promises in the area of smart materials can be found in “smart polymer”. Polymers have many attractive characteristics, such as: lightweight, inexpensiveness, fractures tolerant, and pliable. Furthermore, they can be configured into almost any conceivable shape and their properties can be tailored according to the required needs. The capability of electroactive polymers (EAPs) to respond to electrical stimuli with a mechanical response, is attracting the attention of the scientific community from a wide range of disciplines. Biopolymers in recent decades have been studied as potential electroactive materials. These groups of polymers are extracted from a natural source; thus, they are eco-friendly, additionally they stand as a cheaper solution for the development of smart materials.The present manuscript will explore some of its applications as EAPs.

Cows and Bulls are mainly raised for milk and meat. Cattle Milk and meat play a vital role in the worldwide economies and contribute to food security and nutrition. For greater financial income accumulation, Cattle sourced Food products encompassing milk, butter, yogurt, ghee, cheese, Tenderized meat, meat sausage, etc. are sources of financial income for farmers and food producers. Unfortunately, Cattle Sarcocystosis disease can affect food security, and Cattle farmers’ economies by inducing reduced milk production, weight loss and decreased meat quality, abortion, and even death due to the effect these parasites have on Cattle (Hoeve-Bakker et al., 2019). Cattle Sarcocystosis disease is so far known to be specifically caused by six Sarcocystis spp infections in the Cattle. Each of the six (S.cruzi, S.hominis, S.heydorni, S.rommeli, S.hirsuta, & S.bovifelis) has its own different definitive host The two zoonoses (S. hominis & S. heydorni) share human as their common definitive host. Though the most prevalent among six bovine species, S. Cruzi, is not a zoonosis (Ayazian Mavi et al., 2020), it is a financial burden to the food producers and it may perpetuate malnutrition and Food insecurity. Therefore, Strengthened Control in Food Safety, Food biotechnology, and the Veterinary parasitological sector with the involvement of the public, civil society, and private sector are required to prevent the spread of sporocysts and protect water and Cattle Feed from Sarcocystis spp contamination.

Cattle Sarcocystis spp. infection prevention and control
Статья научная
Cattle Sarcocystis spp. are protozoa. They often parasitise tissues of Cattle. Few of these species are zoonoses. Therefore, they are foodborne parasites associated with consumption of raw or insufficiently thermally treated sarcocystic beef meat. Swallowing oocysts from environmental objects primarily contaminated water, garden crops, grazing on contamited pasture, etc. can cause Cattle sarcocystosis. Sarcocystis spp specific to Cattle include S.hominis, S.heydorni, S.cruzi, S.hirsuta, S.rommeli &S.bovifelis. Among them, S.hominis and S.heydorni are zoonotic and pathogenic agents. Human Intestinal/ Muscular Sarcocystosis is a disease that caused by eating raw or poorly cooked Cattle meat infected by Sarcocystis zoonoses (S.hominis&S.heydorni). Intestinal Sarcocystosis was reported almost from all corners of the world. This has been well documented but no powerful Preventive and control methods available to public yet. With the world growing population, researchers should provide or suggest practical solution to supply safe food to the consumers. During our research work we tried to compare the effectiveness of all available documented Cattle sarcocystis spp. Testing methods to recommend the best one to the public for screening health from infected Cattle before slaughter in the slaughter house. Though culture and society play a fundamental role in foodborne control, we also came up with additional control safety measures recommendations all along the beef meat supply chain.

The results of the selection of new plant growth-promoting bacteria resistant to herbicides of different chemical structure are presented. Two methods were used for screening: sowing on microbiological media from freshly sampled soil and obtaining enrichment cultures from soil samples exposed to herbicides for a month at a temperature of 28 °C. Inoculation was carried out on selective nutrient media containing herbicides Octapon extra (2,5 g/l), Florax (2,5 g/l), Dicamba (1 g/l), Nanomet (1 g/l), Spetsnaz (1 g/l) or Chistalan (2,5 g/l). These herbicides are commonly used to control weeds in wheat crops. The isolated microorganisms belong to the genus Pseudomonas, fix nitrogen, mobilize phosphates, synthesize phytohormones and antimicrobial compounds. They also can mitigate pesticide stress of crops. An anti-stress biological product containing them has been developed and tentatively named "AGROBIOLOG". For its production, the optimal composition of the nutrient medium and the conditions for industrial submerged cultivation on reactors of various volumes were determined. In the laboratory fermenter FA10 with a volume of 10 liters after 72 hours of cultivation at a temperature of 28 °C, a stirrer speed of 200 rpm, aeration of 0.5 volumes of air per 1 min per 1 volume of medium, the amount of viable cells was 28 billion CFU/ml of culture liquid. Cultivation on biological reactors with a volume of 1000 liters under the same conditions allowed to achieve a titer of 6.0 billion CFU/ml of culture liquid.

In the result of the analysis of domestic experience over the last 10 years of foreign experience (for example, 9 countries: Vietnam, India, Spain, Canada, China, Norway, USA, Chile, Japan, which possess the most advanced technologies and equipment for highly efficient production of feed for fish) in the development of innovative technologies and equipment for production of high-performance fish feeds were identified that the methods both dry and wet pressing are outdated and do not meet modern requirements in the production of fish feeds since it does not allow a deep physical-chemical transformations in protein-carbohydrate complex and exercise enter fat components at 40 %. Modern fish technologies are based on the use of extrusion processing of multicomponent mixture to give different buoyancy and adjustable rate of immersion of the resulting feed. Extrusion technology will allow to introduce a large amount of fat into the product - up to 35-40 %, to achieve 100 % starch splitting level. Based on the study of the nutrition of the canal catfish grown in the Central Federal District of the Russian Federation, the nutritional value of each of the components of the feed mixture, providing the need for fish to ensure a significant increase in the growth of live mass and improve the chemical composition of meat, was assessed for different age groups. To solve this problem, the "Feed Optima Expert" optimization program has developed products of extruded feed. Food needs of canal som: 30 - 40 percent protein, 4 - 6 percent fat, no more than 5 percent fiber, 35 - 40 percent Nosazotic Extract substances and 12 - 13 thousand kilos of Joule digestible energy in 1 kilogram (in recalculation on dry matter).

The decrease in catch of valuable fish species from natural water bodies is compensated by their intensive cultivation in artificial conditions. In order to realize the main task of trout farms associated with obtaining marketable products in the shortest possible period of time, artificial feed is used as a source of food. A economically feasible alternative source of raw materials is the products of plant origin. In the process of production of oil and fat products at various stages, numerous fat wastes and by-products are formed, wich have fodder value and are not used as feeding facilities in industrial scale. This is especially frue for fat processing (soapstock of Light oil, fatty bleaching clays, dezodoration chases, phosphatides, calcium salts of fatty acids), as well as waste oils in combination with fat processing waste. On the base of studying the classical technology of producing mixed fodders for valuable fish species and eliminating its drawbacks the technology of pseudocapsulated mixed fodders for salmon fish grown in the CFD of Russia Federation with given fodder value and a line for its realization is suggested. The best way to bring fats and vitamins contained in them to valuable fish species is to feed them as a part of mixed fodders. At present, however, it is difficult to increase the level of fat in feed on the existing Russian fats supply lines, since most plants can include up to 10% of fat in the bulk feed line. Therefore, the development of mixing formulations and techniques for valuable fish breeds using sturgeon fish with more than 10% fat in it as an addition of fat oily wastes such as epaulettes and phosphates is not only of scientific interest. In the course of studies optimization encapsulated optimal feeds for program "Feed Optima Expert" pseudorainbow trout were also developed. As a result, close results were obtained in terms of the rate of growth of trout, the development, conversion of feed and viability in comparison with the best feed counterparts on the Russian market.

Dietary supplements and their effect on the body of students
Статья научная
The world does not stand still. We are daily confronted with the achievements of modern science: we are able to communicate with a person from another continent via the Internet, we easily bypass any distance thanks to different modes of transport. And yet there are things that cannot be automated, improved, accelerated yet. A person still needs to sleep, have some physical activity during the day and, of course, eat. The whole day of a person can easily obey the rhythm: breakfast, lunch, dinner, and, of course, snacks, afternoon tea, brunch, late dinner. And it's getting harder and harder to give up food, as store shelves are bursting with goods that are ready to lie there for years until we buy them. This is because most of the foods we consume contain various dietary supplements in their composition. The main purpose of which is to make them tastier, stored longer, etc. Undoubtedly, the nutrition of all population groups can be affected by food additives, but in this article we will consider young people: 2nd and 3rd year students. Of course, studying, writing course projects, a large number of practical and other classes deprive you of the opportunity, or rather the strength and desire, to eat right. Therefore, this age group is of particular interest. To what extent are students aware of the presence of food additives in their food? How many of the survey respondents monitor their diet? And in general: are dietary supplements as harmful as they say in the media? In this article, we will analyze the survey data of students, as well as understand what dietary supplements are and how they affect the body.

Protein deficiency in the diets of various determined groups of consumers is a serious nutritional problem. The problem of protein deficiency in diets can be solved by developing protein mixtures for their enrichment, taking into account trends in personalized nutrition. Whey processing using membrane technologies corresponds to the concept of Green, Circular, Bio economy. Membrane technologies make it possible to fractionate various whey components and obtain high-tech protein products. The aim of the study is to develop a basic recipe, assess the organoleptic properties and physicochemical characteristics of a dry protein mixture based on whey proteins obtained on the basis of membrane methods. Whey protein concentrate UF WPC - 80 was used as the main component of the protein mixture. Whey protein concentrate and isolate in a 6:1 ratio form the basis of the protein mixture we have developed. We offered options for expanding the range of flavoring additives for dry protein mixtures by combining traditional flavoring additives "Strawberry", "Cherry", "Apple", "Pineapple", "Melon". We have provided an optional addition of papaya and pineapple extracts in case of decreased activity of digestive enzymes, for example, in the elderly people. The technological scheme for obtaining the finished product provides for two-stages dry mixing of the components and the use of commercially available equipment. The protein mixture is a dry powder and is recommended for use in liquid form by restoring it with water, milk or natural juice, for example, veatgrass. We investigated the composition and properties of the developed dry protein mixture in accordance with official and generally recognized test methods. The developed product meets the requirements of TR CU 021/2012 "On food safety" and can be recommended to increase the adaptive capabilities of consumers of various age and physiological groups to physical and neuro-emotional stress, as a fortifying component of diets

In this study, we conducted an experiment to evaluate the effect of pre-sowing seed treatment with 0.05% KCl to the yield and quality of two peanut cultivars L14 and L23 grown in Bac Ninh province, Vietnam. After careful selection, the seeds of L14 and L23 were divided into two parts. Part 1 (control) was treated with distilled water and Part 2 (experiment) was treated with 0.05% KCl. The field experiment was arranged in a Split-plot design with four replications. The results show that pre-sowing seed treatment with 0.05% KCl increased the yield components (weight of 100 pods, weight of 100 seeds, mass ratio of unshelled peanuts, number of pods per plant) and yield of both L14 and L23 when compared to the control, in which the yield of L14 is higher than that of L23. Pre-sowing seed treatment with 0.05% KCl also increased the quality of peanuts such as starch content, reducing sugar, lipid, saponification value, protein, B vitamins, total amino acids and content of some mineral elements in peanuts such as N, K, Ca, Mg. The results of this study demonstrate the importance of pre-sowing seed treatment for peanuts.
