TECHNOLOGY AND APPLICATION OF POWDERED FOOD ADDITIVES FROM VEGETABLE RAW MATERIALS
DescriptionThe market for functional food products is continuously increasing and, according to analysts, by 2020 its share will reach 40% of all food products. The development of the healthy food has been gathering momentum in recent years, the search for non-traditional types of raw materials is constantly being conducted, and new recipes for products enriched with natural food additives are being created. In this regard, special attention is paid to the production and use of powdered food additives from plant raw materials. Theoretical significance and practical applicability of powder technologies in different years was substantiated by such famous scientists as Deryagin B.V., Donchenko L.V., Zimon A.D., Zubchenko A.V., Kasyanov G.I., Magomedov G.О., Paschenko L.P., Rebinder P.A., Tilesnik M.A., Yankhin E.D. In their opinion, using natural food additives, it is possible to obtain functional food products with specified chemical composition and properties. The objects of our research were apricot, grape seeds, pumpkin flesh, black currant and seabuckthorn berries, spinach, apples and flour from lowfat barley. In the course of the study, the effect of dispersity of the obtained powders on their antioxidant activity and frictional properties was studied. The expediency of introducing powders into the composition of multicomponent food products for enriching them with carbohydrates, vitamins and microelements is shown. The organoleptic evaluation of the produced powders showed that they have high taste values. The study of organoleptic and microbiological indices of products enriched with such powders indicates prolongation of their shelf life. As the main results of the study, we note the assessment of the chemical composition of the powders from the investigated objects, as well as the improvement of the technology of drying of plant raw materials with sparing technological regimes of its implementation

Description
Technologies of fruits storing known at the present time, solving actual problems – slowing down biochemical processes, inhibiting ethylene synthesis, do not provide fully the preservation of quality of fruits due to not taking into consideration the peculiarities of microflora of fruits and microbiological processes, taking place during storage. Purpose of the research: investigation of influence of complex treatment of fruits with electromagnetic fields of extremely low frequency (ELF EMF) and the biopreparation “Vitaplan” on changing of losses of biologically active substances in the process of longterm storage. Objects of the research: apples of the Idared variety and pears of the Conference variety, regionalized in the Krasnodar region. Mass shares of the vitamin C and P-active substances were measured in the process of storing. ELF EMF treatment was conducted on an experimental installation. Fruits were exposed to the action of electromagnetic fields with specified parameters. Complex treatment of fruits (apples and pears) with ELF EMF and the biopreparation “Vitaplan” before dispatching for storage allows preserving the biologically active substances – the vitamin C and P-active substances – to the maximum degree. Synergetic effect, appearing due to the complex action of electromagnetic field and the bio-preparation, allows decreasing the processing time in the electromagnetic field

PARAMETERS OF RESEARCH ACTIVITY OF STUDENTS AS CRITERIA FOR DIAGNOSTICS OF EDUCATIONAL ENVIRONMENT
DescriptionThe article reflects the relationship between the parameters of research activities of students and the characteristics of the educational environment in higher education. It is known that the research activity of students is an integral part of the educational process, therefore, the parameters of research activity can and should be indicator variables reflecting certain aspects of the educational environment. According to modern views, all types of research activities of students (educational, research, scientific and practical and research) is the most important mechanism for the development of their research competence. In addition, the parameters of research activities of students - the reflection of the relationship of scientific and educational activities in higher education, and this - one of the most important factors of competitiveness of the educational environment. The authors substantiate that the parameters reflecting the research activity of students characterize, first of all, such aspects of the educational environment as its intensity, social activity, dominance, coherence, mobility, stability, reliability and efficiency. This is due to the fact that the research activity of students is a transdisciplinary process that depends on the same factors as the educational process as a whole and is characterized by the same didactic goals (tasks) as the educational process as a whole. In identifying the relationship between the parameters of research activities of students and the characteristics of the educational environment, the authors also took into account the relevance of such a task as ensuring continuity between levels of continuing education. The theoretical significance of the results of this study is that they can be the basis for further scientific understanding of the problems of the quality of education and the effectiveness of educational environments, the practical significance is that they can be applied in the systems of socio-pedagogical and psycho-pedagogical monitoring and the effectiveness of the educational environment, as well as monitoring the student's personal and professional development). Methodological bases of research: system, sociological, competence, probability-statistical and qualimetric approaches (leading methodological basis - competence approach). Research methods: modeling; methods of graph theory, sets and relations; systemiccognitive analysis; methods of qualimetry (theory of latent variables); methods of mathematical statistics (first of all - the method of rocky scree); methods of the theory of limits

Description
Fruits are an important part of the diet of humans and many animals. In case of an improperly organized process of storing of fruits, the loss of mass and decrease of quality can be substantial. This makes relevant the research, aimed at enhancing existing and developing new technologies of fruits storing. In this article, the results of the investigation of influence of complex treatment of fruits with electromagnetic fields of extremely low frequency (EMF ELF) and а biopreparation on the change of microbial contamination of their surface and on the loss of mass in the process of long-term storage are revealed. Apples of the Idared variety and pears of the Conference variety were the objects of research. The change of microbial contamination of the surface of fruits, undergone a few types of pre-treatment (EMP ELF, bio-preparation “Vitaplan”, complex treatment “EMP ELF + the biopreparation” and no special treatment), after storing during 7 months in case of pears and 8 months in case of apples is shown in the article. It was found, that the greatest decrease of content of microorganisms on the fruits’ surface is achieved as a result of the complex treatment, combining the treatment with EMP ELF and an aqueous solution of the “Vitaplan” bio-preparation. The effective parameters of such a treatment for apples and pears are represented

DescriptionThe article presents the results of studying the influence of the method of treatment before storage and storage parameters, including the relative air humidity, on the value of general losses of carrots. The taproots treatment before putting into storage was carried out with electromagnetic fields of extremely low frequency and the bio-preparation Vitaplan. After treatment, the taproots were kept at a temperature of +2±1°С for 56 days and +25±1°С for 21 days. In the process, the relative air humidity was changed from 40 to 90%. At a storage temperature of +2±1°C, the lowest total loss was observed at a relative humidity of 90%. At a storage temperature of +25±1°С, the optimal, from the point of view of decreasing the general losses, turned out to be the relative air humidity of 70%: with decreasing relative air humidity to 40%, significant increase of natural losses was observed, because the taproots were losing water intensively, and with increasing relative air humidity to 90%, favorable conditions were created for the growth of pathogenic microflora, which caused significant losses from the microbiological decay. The method of pretreatment of carrot taproots, providing the lowest general loss during storage in all the studied conditions, was joint treatment with ELF EMF and the bio-preparation called Vitaplan
