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.

INNOVATIVE TECHNOLOGY OF DUALSTAGE OBTAINING RAW JUICE AND ITS PURIFYING IN SUGAR INDUSTRY
DescriptionThe typical scheme of sugar beet processing, used at most sugar beet factories in Russia has not been fundamentally changed for several dozens of years. As a result, the performance indicators of domestic beetprocessing enterprises are below the world average. The article considers the technology of two-stage extraction and subsequent lime-carbon dioxide raw juice purification with the separation of the preliming sludge and carrying out the carbonation treatment in one step. The theoretical foundations of a two-stage extraction of sucrose from sugar beet cossettes are described and the main criteria for its implementation are given. The chemistry of calcium compounds upon activation of a suspension of saturation precipitation, returned to a progressive preliminary defecation, is shown. On that the increasing of sedimentationfiltration properties of the preliming sludge is based that allows its separation on the existing equipment in based. The theoretical premises for carrying out saturation in a homogeneous liquid-liquid environment are given and practical principles for their realization are described. The comparative evaluation of existing and improved sugar beet processing technologies is carried out. The improved technology makes it possible to reduce the amount of raw juice while improving its purity, thereby reducing the consumption of auxiliary materials, fuel and energy resources, simplifying the technological scheme while improving the quality of the purified juice, namely, its higher purity, achieved by reducing the degree of transition of high-molecular compounds in it and increasing the effect of destruction of reducing substances

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

Description
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

Description
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
