The import substitution program contributed to intensive growth of domestic viticulture and winemaking. In the southern regions of Russia, more than 250 thousand tons of grapes are processed into juice and wine every year. More than 50 thousand tons of grape pomace can be used for producing more than 1 thousand tons of grape oil and tens of tons of protein filler, dietary fiber, pectin and organic acids. However, secondary raw materials are usually not immediately sent for processing. Therefore, grape by-product safety issues are relevant. The article suggests methods for processing byproducts of grape varieties grown in the Chechen Republic. It describes a method of gentle drying of grape pomace which preserves maximum valuable components. Technological parameters for extracting valuable components from dry grape seeds and skins using liquid carbon dioxide are suggested. Information for identifying the chemical composition of carbohydrate-protein-lipid meal from grape seeds and recommendations on its use as a food fortifier are given. Technological methods for producing natural food supplements from secondary products of viticulture and winemaking involve using a new class of supplements-CO2-extracts and CO2-meal from seeds and skin of the grape variety grown in Naursky district of the Chechen Republic. Owing to developed comprehensive preventive measures, strict production control of all production stages can be carried out and measures aiming to ensure safety of fortified products and prevent food diseases can be taken. The study confirmed food and ecological safety of products which contribute to human health.

The process of quenching a flame of liquid hydrocarbons by suspensions of water with carbon nanostructures is studied. It is shown that the dispersion of carbon nanostructures in water intensifies heat transfer in liquids, which leads to their more rapid heating to boiling temperature under conditions of thermal exposure to a flame. During the experiment, it was found that the quenching time of liquid hydrocarbons by nanosuspensions is on average 3.5–5.0 times less than the time of quenching of a liquid with finely divided water.

The article presents material on the production of a new class of bio-correctors in the form of cryopowders from fruit raw materials grown in the Adler district of the Krasnodar Territory. Fruits of shadberry, feijoa and persimmon are chosen as research objects. Fruits have high characteristics of quality, but low shelf-life. The chemical composition of fruits contains a significant amount of easily digested carbohydrates, vitamins, macro and micronutrients. The dependence of the moisture content of fruit raw materials on the duration and speed of low-temperature drying is investigated. Mathematical substantiation of the freezing process and the contribution of dry substance heat capacity, ice and water to the heat generated during the water crystallization are given. The technological apparatus scheme for the production of cryopowders from fruit raw materials has been improved. It is based on raw material dehydration in a gaseous nitrogen environment, shock low-temperature freezing of research objects and ultrafine grinding of pre-prepared and dried raw materials in a liquid nitrogen environment.

A technology, based on the production of wine beverages from grape cryopowders in the mountain-valley zone of the Republic of Dagestan, is proposed. The data on the vacuum microwave drying of grape raw materials and subsequent grinding in a cryomill are presented. The modes of grape raw material preparation and its subsequent dehydration and cryo-grinding, which provide the possibility of successful use in the dried state in the production technology of wine drinks, are proposed. The principal feature is the use of whole grapes as a raw material, with rinds and seeds. The physical and chemical indicators, the content of phenolic substances and the organoleptic indicators of wine beverages made according to the traditional technology and the beverage made from grape cryopowders were studied. A comparative assessment of beverages was made. It is established that vacuum microwave drying conduces to better preservation of the properties of raw materials and finished products. The organoleptic assessment showed that the wine drinks developed according to the proposed technology had a more intense color and a more pronounced flavor of sweetness and sourness than traditional wine beverages. The advantage of this technology is the ability to transport grape cryopowders in unregulated temperature conditions to any point close to the consumer and carry out the production of wine beverages there.

A technology has been developed for biopowders production from fruit raw materials grown in the Chechen Republic. The data on vacuum microwave drying of fruit raw materials under the influence of an amplitude-modulated magnetic field with carrier frequency of 180–20 kHz and modulating frequency of 10 to 30 Hz, with magnetic induction value of 5 mt. The proposed regimes of dehydration of fruit raw materials and its subsequent grinding by gas-liquid ”explosion”, providing the possibility of successful use in dried state in production technology of soft drinks. The peculiarity is the use of ecologically clean fruits of apricots, cherry plums, cherries, pears, melons and plums grown in Shelkovsky district of the Chechen Republic as raw materials. We studied physical and chemical indicators, content of phenolic substances and organoleptic indicators of fruit raw materials, powders and beverages. We also conducted comparative assessment. Under the influence of EMB ELF vacuum microwave drying of fruits contributes to better preservation properties of raw materials and finished powders. Organoleptic evaluation showed that non-alcoholic beverages produced on the proposed technology had intense color and more pronounced flavor of sweetness and acid compared to traditional non-alcoholic beverages. The advantage of this technology is the possibility to transport components for beverage production at unregulated temperature conditions to any location that is close to the consumer and carry out the production of soft drinks there.
