Based on the complex of studies carried out, the formulation of wafers (wafer sheets) enriched with food additives "Powder from the tubers of Jerusalem artichoke" and skimmed sunflower lecithin was developed, as well as the formulation of fat filling enriched with a complex of food additives "Powder from tubers of Jerusalem artichoke", "Powder from hips" And low-fat sunflower lecithin. A recipe was developed and an assessment of the organoleptic and physicochemical parameters of enriched waffles with a filling was made. The storage period, ensuring safety and maximum preservation of consumer properties, was established. The study of the nutritional value of the developed waffles with filling allowed to establish that in comparison with the control sample they contain inulin and vitamin C, while the degree of satisfaction of the daily demand for these nutrients with consumption of 100 g of the developed product is 16.46 and 24.65% respectively. In addition, the developed products, in comparison with the control sample, are characterized by an increased content of dietary fiber, potassium, magnesium, phosphorus, iron, vitamins B1, B2 and B6

The article presents the results of studying the influence of some types of packaging materials used in conjunction with Inter Fresh’s ethylene absorber (sachets) on commercial quality and losses of Alexandria zucchini, Lyubov sweet pepper and tomatoes cv. Inkas during storage. The study was carried out using StePac Xtend bags, creating a modified atmosphere. The objects of research were stored for 14 days at a temperature of 8 – 10 °С and air relative humidity of 90±3 %. One sachet for ethylene absorption was placed in Xtend bags. It was found that when stored under these conditions, the total weight loss is: for tomatoes – 0.3% when using Xtend bags and Inter Fresh ethylene absorbers, 1.8% when using traditional packaging materials; for zucchini – 0.4% when using Xtend bags and Inter Fresh ethylene absorbers, 1.6% when using traditional packaging materials. Losses associated with microbiological damage during storage of zucchini and tomatoes were not observed. During storage of sweet pepper microbiological spoilage took place, which, apparently, was the result of increased contamination with pathogenic microorganisms

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

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

The article presents data characterizing the composition of macro and micronutrients from secondary resources of pumpkin processing – pumpkin pomace. We have found that extracts of pumpkin are valuable raw materials for the production of food additives, as they contain proteins, dietary fiber, including pectin and protopectin, minerals, as well as such biologically active substances as vitamin C, β- carotene and P-active substances using nuclear magnetic relaxation, it is shown that pretreatment of pomace pumpkin in the microwave electromagnetic field of certain parameters before IR drying allows to transfer part of the bound moisture free moisture, that allows to intensify the subsequent process IR drying. We have developed an innovative technology of production of food supplements from pumpkin extracts, which is protected by Russian patent for the invention and having the “know-how” status. The article presents data describing the organoleptic and physical and chemical indicators of quality nutritional supplements, formulated according to the developed technological regimes

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

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

The article presents the results of the patent research in the field of modern production technologies of Inulin from plant material. It has been established that the differences of the currently known methods of production of inulin are concluded in selecting raw materials pretreatment inulin-containing modes type extractant and extraction methods, methods of purification inulincontaining extract and methods for producing the final product. A significant amount of Inulin production methods is based on use of freshly feedstock. A number of methods have been patented involving the extraction Inulin from plant raw materials previously stabilized by drying. In most of the methods, inulin extraction is carried out at elevated temperatures with water or aqueous salt solutions. Several technologies involve extraction with organic solvents at low temperatures. Have been patented several processes in which the extraction is replaced by a separation process using inulincontaining juice and physical and mechanical methods. Some of the known processes provide for the extraction process to further operations, such as blanching vegetable raw materials, sonication, vibration impact, processing enzymes. The most promising direction to improve manufacturing technology of inulin from fresh plant raw materials is to conduct research on the use of electromagnetic fields at microwave frequencies, the inactivating effects of which on enzyme systems is an established fact that, in turn, would eliminate the use of chemical agents for inactivation of oxidative enzymes. In addition, considering that more effective are the methods for the preparation of inulin from freshly harvested plant material, are relevant researches on development of innovative technologies to prepare it for storage and its storage, which will provide inhibition of unwanted biochemical and microbiological processes that occur during storage and lead to a loss of inulin
