"Зеленые" технологии с применением двуокиси углерода в пищевой промышленности

Кошевой Е.П., Гукасян А.В., Косачев В.С.

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...

Trong Le V., Thinh Bui Bao

Статья научная

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.

Machinability of stainless tool steel using nitrogen oil-mist coalant

Elshwain Amad E., Elmunafi Mohamed H., Yusof Noordin M., Redzuan Norizah, Kurniawan Denni, Wahab Hassan A., Mohamed Yasir A.

Статья научная

For all dry machining process, temperature generated in the cutting zone is the major challenge. It causes tool failure and results in unsatisfactory surface finish. Application of flood coolant method during machining processes can significantly reduce the temperature and consequently extend the cutting tool life. However, it has serious concerns regarding environmental pollution, operator health and manufacturing cost. These issues are usually attempts to be overcame by using minimum quantity lubrication (MQL) technique. This method merges the advantages of both dry cutting and flood cooling by spraying a small amount of lubricant to the cutting zone using vegetable oil. In this paper, another technique is proposed in order to further enhance the machineability of the stainless tool steel (STAVAX ESR 48 HRC). This involves using of nitrogen gas (N2) and air as cooling medium in combination with oil mist lubricant (MQL). The results show that the combination between nitrogen and oil-mist lubricant much more prolonged the tool life and improved the surface finish than the air-oil mist lubricant medium.

Djimasbe R., Ivanov V.B., Kemalov A.F., Kemalov R.A., Valeev T.F., Nerobov N.

Статья научная

In this article, a review of the literature on the technology for producing elemental sulfur-based paving material was reviewed, and a laboratory test of this technology was conducted at the Department of Highly Viscous Crude Oil and Bitumen. Natural. Attempts to mix sulfur with bitumen to reduce the cost of road construction and sulfur use were undertaken earlier, but the resulting blends did not provide the appropriate quality and the process was difficult to implement. The article proposes a unique technology to obtain not a physical mixture, but the formation of a chemical bond between sulfur and bitumen with the formation of bitumen polymers. This technology becomes possible with the use of a catalyst specially developed by the initiators of the project and has no equivalent in the world practice. And we add that the subject of the production of sulfur bitumen is not a question of actuality on the one hand since 1970, many researchers are interested in this subject but as with the abundance of oil and no one question about alternative solutions, and today with the reduction of traditional oil this theme is really soliciting.

Hassanpour F.

Статья научная

Gums refer to a type of polysaccharides which are used to increase viscosity and create some other functional properties such as thickening agent, emulsifying agent, stabilizer, crystal inhibitor and so forth. They are classifying based on their nature and originality including, microbial, plant, exudate and animal Gums. This article shortly reviews a group of plant Gums and recent findings in their application. Gums or Hydrocolloids are main compounds which create stability of emulsion via entering into water phase. The importance of these compounds is on viscosity and electrostatic reactions to stabilize nonalcoholic emulsion with below properties; 1) easily soluble in cold water, 2) the lowest amount of viscosity in water, 3) having maximum level of emulsifier amount, 4) no creation of gelling. Diversity and functionality of Gums and regarding their still novelty in food industries have made Gums one of the main additives in food formulations. Since sourced of Gums are different we must focus on using them together to improve their synergistic effect but interactions among them and combined matrixes produced by them also need to be studied in details.

Статья научная

Fixed assets are an integral component of the productive capacity of any enterprise. The financial results of the enterprise largely depend on their intensity and efficiency of use. The analysis of fixed assets is usually carried out using an integrated and systematic approach, based on their availability, their movement, efficiency of use (including their active part). In the opinion of some authors, the traditional methods of analyzing fixed assets have a number of shortcomings, since they do not take into account the life cycle of an enterprise, the ecological aspects of the operation of fixed assets, the operation specifics of the individual divisions of a company and its branches. In order to improve the methodology for analyzing fixed assets, the authors proposed to use formalized and non-formalized criteria for analyzing the risks associated with the fixed asset use. A survey questionnaire was designed to determine the likelihood of the risk of economic losses associated with the use of fixed assets...

The mechanisms of implementation of the state programs in the agrarian sector of economy

Apyrbaev G.A.

Статья научная

Modern studies in the field of public administration confirm the high efficiency and prospects of using targeted programs at various levels. The formation and realization of targeted programs in the implementation of the agrarian policy of Russia allow of solution of the most significant problems of the latter, while observing all planning principles and constantly monitoring the results achieved. The author of this article analyzes the use of targeted programs on the example of the “State Program for the Development of Agriculture and Regulation of Agricultural Products, Raw Materials and Food Markets”. He considers the directions and causes of its changes, the amount of financing aimed at its implementation, the distribution of responsibilities for its implementation and monitoring. The author also compares this program with the similar one at the level of the Voronezh region, identifies and substantiates common features and signs of difference. In addition to the positive aspects, it is indicated that the regional authorities are not yet fully aware of and so do not use the level of independence available to them in the formation and implementation of agricultural policy. The article proves the strategic nature of program-target planning, its specificity and systemic nature, which makes it attractive for public administration. A general conclusion is drawn on the effectiveness of targeted programs as a mechanism for implementing agricultural policy at the national and regional levels.

Lettuce (Lactuca sativa) is a major leafy vegetable and is commonly used in salad mixes and sandwiches. Therefore, lettuce can contribute significantly to the nutritional content of healthy diets. One specific nutritional problem that needs attention is mineral (e.g., Fe, Zn) malnutrition, which impacts over two-thirds of the World’s people living in countries of every economic status. Also, consumption of salads Microgreens, the edible cotyledons of many vegetables has been gaining popularity as a culinary trend due to its flavor and density of minerals that can be sustainably produced in almost any locale. In this study, the nutrient contents of both mature and microgreen oakleaf lettuce grown on rockwool mat were assessed and compared to each other together with the phytonutrient contents like ascorbic acid, total antioxidant capacity and total phenolic content. Of the 10 nutrients examined (P, K, S, Ca, Mg, Mn, Cu, Zn, Fe, N), lettuce microgreens had significantly larger quantities of all nutrients than mature lettuce except for the Ca and K. As microgreens can be grown easily in one’s home using the methods used in this study, they may provide a means for consumer access to larger quantities of nutrients per gram plant biomass relative to store-bought mature lettuce, which had relatively lower nutrient contents than microgreens with respect to most nutrients examined.
