abstract 1201606037 issue 120 pp. 537 – 551 30.06.2016 ru 186
The article analyzes the existing technologies and methods of storage of tubers of topinambur. We have analyzed the traditional methods of storage of tubers of topinambur - in containers, boxes or bags in storage or in the ground clamps. Russian and foreign topinambur tubers storage technologies in modified atmosphere, with use of easily removable wax coating, with plant extracts treatment, at different storage temperatures are studied. We have also carried out analysis of scientific and patent sources led to the conclusion that existing technologies and methods of storing topinambur tubers, which do not allow reducing to the maximum extent the weight loss and the inulin hydrolysis during storage. A reasonable conclusion was made about the advisability of further studies in the field of innovative technologies and methods of preparation for storage and storage of topinambur tubers, ensuring minimal weight loss, as well as maximum preservation in their structure of inulin, vitamin C and other biologically active substances during storage

abstract 1311707060 issue 131 pp. 709 – 719 29.09.2017 ru 166
The article provides experimental data, which help to substantiate the effectiveness and feasibility of application of plant resources, produced by the rubbing of the pears in the production process of puree as raw material for the production of secondary food additive. For the first time, with the use of pulsed NMR it is established that processing of secondary resources of pears processing in UHF EMF influence on the redistribution of bound and free moisture, i.e., the maximum transition was for linked moisture to free moisture, noted in the processing of secondary resources in UHF EMF with the rate of heating (increase in temperature) 0,4 °С/s to a temperature of 60 °С. It is established that such processing of secondary resources of processing of pears allows to increase the average speed of the subsequent IR-drying and reduce the time IR drying in 2 times in comparison with IR-drying of control sample (without pretreatment in UHF EMF). Pre-treatment of secondary resources of processing of pears to UHF EMF for the identified modes allows for their subsequent IR-drying to reduce the loss of vitamin C, 23.9% and P-active substances – by 20.6% compared with the control sample. We have developed technological modes of production of food additives from secondary resources of processing of pears, providing maximum preservation in its composition of thermolabile biologically active substances – vitamin C and P-active substances. On the basis of these studies, there was developed a set of technical documentation, including TU 10.39.25-423- 040801346-2016 "Food additive. Pear Powder" and a technological instruction for the production of food additives

INFLUENCE OF THE METHOD OF TREATMENT BEFORE STORAGE AND STORAGE PARAMETERS ON THE VALUE OF GENERAL LOSSES OF CARROTS

abstract 1461902001 issue 146 pp. 0 – 0 28.02.2019 ru 30
The 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

abstract 1311707037 issue 131 pp. 450 – 461 29.09.2017 ru 104
Long-term storage of fruits can be achieved by means of decreasing microbial contamination of their surface as a result of fruits pre-treatment by biopreparations before dispatching for storage. In the current study patterns of influence of fruits pre-treatment with the “Ekstrasol” biopreparation in a number of concentrations of bioagent on the microbial contamination of their surface during storage are revealed. The “Ekstrasol” preparation is a biofungicide, containing the Ch-13 strain of Bacillus subtilis bacteria and their metabolites. As research objects there were chosen apples of a zoned in the Krasnodar region variety called Idared and pears of a zoned in the Krasnodar region variety called Conference, harvested in 2016. The apples and the pears were stored over a period of 6 months in the low temperature conditions. Samples were withdrawn every month over the period of storing. The species composition and quantity of the most prevalent microorganisms, potentially causing the spoilage of apples and pears during storing, were identified. The optimal concentration of the bioagent, which provides the maximal decreasing of microbial contamination of fruits’ (apples and pears) surface, is established – 106 CFU/g, dosage of solution – 1 ml per 100 g of fruit

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.

abstract 1321708087 issue 132 pp. 1111 – 1121 31.10.2017 ru 126
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
