Rational use of grapes processing resources is among environmental problems of AIC of Republics of the North Caucasus and Krasnodar Territory. Currently, waste from grapes processing is not practically used and worsen the ecological state of environment. The research subject is a technology based on the production of cryo-powder from pulp, squeeze, seeds and grapes skin grown in the foothill and mountainous regions. The prerequisites for research were previously performed author works on related topics. The data on vacuum SHF-drying of grape raw materials and subsequent grinding in a cryomiller are given. Modes of preparation of grape raw materials and its subsequent dehydration and cryo-grinding, which provide the possibility of successful use in the dried state in the production technology of wine beverages, are proposed. The principal feature is the use of whole grapes as a raw material, with skin and seeds. Physico-chemical parameters, the content of phenolic substances and organoleptic characteristics of wine beverages made according to the traditional technology and the beverage made from grape cryo-powders are studied. A comparative assessment is made. It is established that vacuum SHF-drying contributes to better preservation of the properties of raw materials and finished products. The organoleptic assessment has shown that wine beverages developed according to the proposed technology had a more intense color and a more pronounced taste of sweetness and acid than traditional wine beverages. The advantage of this technology is the ability to transport grape cryo-powders in unregulated temperature conditions to any point close to the consumer and carry out the production of nutritional food there.

The article presents the results of studying the qualitative composition and quantitative content of some groups of phenolic compounds in 11 types of medicinal plants growing in the foothills of the North Caucasus, and provides the estimates of the antioxidant activity of extracts from these plants. The qualitative and quantitative content of phenolic compounds was determined using a Kapel-105M capillary electrophoresis system, and the total antioxidant activity of the extracts was measured on a Tsvet Yauza-01-AA device with an amperometric detector. In the studied plant samples, the total content of tannins was determined, eight phenolcarbonic acids were identified and quantified, as well as quercetin and rutin — two of the most important flavonols. The highest total content of phenolcarbonic acids (11,776.2 mg/kg), as well as the highest antioxidant activity were noted in the aqueous extract obtained from Echinacea purpurea (lat. Echinacea angustifolia). The direct relationship between the antioxidant activity of the studied medicinal raw material and the content of phenolic compounds has been experimentally established as follows: the higher is the concentration of phenolic substances, the higher is the antioxidant activity. The results of this study provide new information on the composition and content of phenolic compounds in some types of wild-growing plant raw materials of the North Caucasus and the antioxidant activity of extracts based thereon that will facilitate the use of the studied plants as a potential source of natural antioxidants in the production of functional materials.

The problem of obtaining and rational use of whey proteins in human nutrition today is solved all over the world, traditional methods are being improved and new, more effective ways of processing milk whey, aimed at maximizing the withdrawal and use of its proteins, are being developed. The aim of the research was to develop the technology of albumin cheese ricotta from serum derived by the action of various coagulants. The raw material for cheese production was serum. For the study, two samples of cheese (with a threefold repetition) were made: Sample 1 - using serum formed during the fermentation of proteins with the participation of citric acid (normalized mixture + enzyme + citric acid); Sample 2 – using serum formed during protein mixing with the direct introduction of the fermentation culture (normalized mixture + enzyme + culture + calcium chloride). Determination of organoleptic and physico-chemical parameters in samples of albumin cheese, obtained from the developed technology, was carried out immediately after manufacture. The study of organoleptic characteristics of cheeses showed a similarity of indicators in samples 1 and 2. In particular, it was stated that pure, fresh taste and smell, with a specific albumin flavor, without foreign flavors and odors. Consistency in 1 sample was homogeneous, creamy, in 2 samples it was tender, but with a slight splinting. The color of the cheeses was white uniform throughout the mass. The lower acidity in the sample 2, which was at 17 °T, whereas in the sample 2 was higher – 20 °T. This, in particular, is explained by the use of citric acid for coagulation. The changes of microbiological parameters in the raw materials during storage, which consisted in the growth of the number of mesophilic anaerobic and optional aerobic microorganisms in two samples of cheese, were established. Given the permissible level of the number of mesophilic anaerobic and optional aerobic microorganisms in cheese not more than 1 × 105 CFU/g, the shelf life of two samples of cheese for 5 days. Indicators of titrated acidity during storage were correlated with changes in the number of mesophilic anaerobic and optional aerobic microorganisms. The mass fraction of moisture in the samples of cheese in the process of their storage decreased.

In recent years, goat breeds with a dairy-meat-wool or combined productivity type, represented by local breeds that are bred mainly in the foothills and mountainous regions of the North Caucasus, Altai, Tyva and Khakassia, have become increasingly widespread in Russia. The Karachay goat population is the most interesting for research, since in their breeding was aimed at obtaining animals with a number of unique productive characteristics and capable of producing the required outputs under the harsh conditions of the mountain and foothill zones of the Caucasus. In view of the limited research on these animals, in particular their reproductive functions, the aim of this study was to investigate the natural implementation of the reproductive function of the Karachay goats in different geographical areas of breeding. There are slight differences in some parameters of Karachay goat reproduction in high mountain zone (from 2000 m a.s.l.) and middle mountain zone (1000–1500 m a.s.l.). An important conclusion is that the recognized low fertility of the Karachay goats is not genetically determined. Analyzing the number of ovulations and fresh yellow bodies in the ovaries by laparoscopy using Karl Storz (Germany) endoscopic equipment, the authors found a potential fecundity of 3.1 (2.8 to 3.4).

In the farms of the north-eastern slope of the Greater Caucasus wood raw material obtained from intermediate felling, is not fully utilized and is not effective, due to the organizational and technical difficulties of farms. In addressing these issues in 8 directions of the region with a length of 40-50 km 14 intermediate assembly points were organized, which are intended for the collection and temporary storage of wood raw material harvested within a radius of 15-20 km of the forest. Need to establish assembly points is due to the complexity of relief items and the possibility of year-round use of the main roads of regional importance. To ensure uninterrupted timber industry and in full at the assembly point accumulated wood raw material is partially sorted. Processing of harvested wood raw material is planned for timber industry, located near the central region of the main road in the territory of Cuba town. Establishment in the area of the complex is considered justified, since the resource base in the coming years for intermediate, and later for the main use will be more than 100 thousand hectares of forests in the region. In the proposed area for the industrial complex for processing of raw wood there are all the technical and economic prerequisites. Accumulated in the assembly points wood raw material to the point of processing is transported using self-loading lumber carriers of up to 8 meters length, which is associated with a complex terrain conditions and road network in the region. This complex is planned to organize the following process areas: sawmills, parquet and packaging, small-chip technology, processing of technical greenery. In organizing the production sites size and quality characteristics and volumes of each category of harvested wood raw materials are taking into account, as well as the need for forest products in the region and the country as a whole. In the processes it is envisaged to use the most advanced modular processing of wood with the release of standard lumber, wood workpieces of different products, pulp chips, wood greens and products of its processing.

The results of studies of the content of polyphenolic compounds and their antioxidant activity in the Pontic hawthorn plant Crataegus pontica K.Koch., growing in the mountainous regions of the Tashkent region of the Republic of Uzbekistan are presented. The collection of raw materials took place in the spring at the beginning of October 2019 and at the end of April 2020. The conditions for the isolation of polyphenolic compounds were selected under various conditions. It was shown that the optimal content of polyphenols is extracted with 70% acetone, followed by fractionation of the aqueous residue with ethyl acetate and precipitation with hexane. It was shown that in the plants harvested in spring, the amount of polyphenols was 4.28%, and the collected volume was 2.6%, of the air-dry mass of the raw material. Chromatographic methods (BC and TLC) revealed that the composition of plant leaves collected in spring contains more polyphenols than those collected in autumn. This plant contains compounds belonging to the class of flavonols, phenolic acids and flavan-3-ols. Polyphenols were identified by rutin, quercetin, quercetin-3-O-β-galactoside, catechin, and gallic acid by BC and TLC methods. The antioxidant activity of the sum of polyphenolic compounds was studied in the model of lipid peroxidation (LPO) in rat liver mitochondria. It was found that polyphenols have a protective effect on mitochondria, a reduced damaging effect of Fe2+ / ascorbate and antioxidant activity depends on the concentration of the studied polyphenolic substances. The introduction of rutin into the incubation medium in 5 μM medium inhibits LPO processes by 32.0%, and at 10 μM – by 85.9% and in 20 μM – by 96.8%, compared with the control.

Aim. To analyze the scientific and technical literature and identify ways to create a new generation of mass-consumption food products enriched with vital nutrients. Discussion. The main malnutrition of the Russian population is the excess of caloric intake over an indicator of the level of energy consumption. One of the ways to solve this problem is the production of functional food products or enriched functional products. The essence of this is that only those micronutrients that are really in short supply should be used in the fortification of products. These should be products of mass consumption, and especially those that undergo refining, which results in the loss of micronutrients. The use of raw materials and ingredients only of natural (animal, vegetable, mineral) origin, allows you to create active complexes that qualitatively change the physiological properties of the product, and can affect many product characteristics and processes such as physico-chemical, structural-mechanical and organoleptic characteristics of the product, the processes of color formation, fermentation, oxidation, storage capacity. However, sometimes a strong passion for enriching the product with useful macro- and micronutrients affects the taste characteristics. Conclusion. When developing recipes and technologies for new-generation products, it is necessary that the enrichment of the product with important and necessary elements does not worsen the organoleptic characteristics. At the same time, it is necessary to ensure the safety of products without compromising consumer properties. The diet should contain all the necessary nutrients (nutrients) for a person in sufficient quantities and balanced with each other in the most favorable proportions.

В статье излагаются результаты инструментальной съемки и шурфовки на раннесредневековом городище, выявленном в начале 1970-х гг. Х. Х. Биджиевым. Городище и связанное с ним селище занимают высокое мысовое плато над каньоном левого берега р. Кумы в Карачаево-Черкесии. Площадь укрепленного городища – 4 га, селища – немногим меньше. С трех сторон городище абсолютно неприступно, с четвертой, западной, надежно защищено высоким валом и глубоким рвом. На городище и селище зафиксирован ряд западин, которые, скорее всего, являются заросшими остатками построек. Содержимое шести шурфов – каменные развалы фундаментов (?) строений и фрагменты сосудов. Керамика может быть датирована VII–X вв. н. э. Памятник являлся одним из звеньев в цепи достаточно известных (несколько десятков) укрепленных крепостей данного времени в предгорьях и горах Северного Кавказа. Строительство сети сложных оборонительных сооружений свидетельствует о высокой строительной культуре и социальной дифференциации общества в это время. The article presents the results of instrumental surveys and pitting at an early medieval site, identified in the early 1970s by Kh.Kh. Bidzhiev. The investigated site and the settlement associated with it occupy a high cape plateau above the canyon of the left bank of the river Kuma in the Karachay-Cherkess Republic. The object of study is located in 2.4 km south-west of the southern outskirts of the village Krasnovostochny. The area of the fortified site is 4 hectares, the area of the settlement is slightly less. On three sides, this site is absolutely impregnable. On the forth western side,on its western slope, it is reliably protected by a rampart of up to 6 to 7 m high and a moat of1 to 2 m deep. On the outside of the southern part of the rampart, a small outcrop of masonry constructed of the large blocks of limestone formed in the dry stone wall was discovered. The gates to the site were most likely located on the northern side of the rampart, in the place where a slight decrease was discovered, not at the southern end of the rampart (according to Bidzhiev) because no sign of an entrance was found there. The site revealed several shallow depressions of a sub-square, sub-rectangular or oval shape with a noticeable roller along the contour. There are at least 7 such depressions in the sectional area from 8 to 15 m. Probably, these depressions are the overgrown remains of the foundations of some buildings in the central part of the site. The content of 6 pits made on the territory of the site and the settlement are stone remains of the foundations (?) of ancient buildings and fragments of vessels. The collection of ceramics consists of medium-sized fragments of the walls of pottery (?) vessels, or vessels that are corrected on a wheel. The ceramics are diverse in the color of clay, density of the paste, firing, and impurities. According to the character, paste and collar shapes, ceramics can be dated to the last third of the 1st millennium AD, which does not contradict the opinion of the site’s discoverer on this issue (7th to 10th cent. AD). The examined site was one of the links in the main chain of fairly widely known (several dozen) fortified stone fortresses of this time in the foothills and mountains of the North Caucasus. Specialists know more than 130 similar stone sites, sometimes located in groups in the foothills and mountainous regions: settlements with defensive stone walls. Such small fortresses were built every 2 to 3 km along the tip of the cape above the river. The construction of a network of complex defensive structures indicates a high building culture and a social differentiation of society at the time.

The article presents an assessment of technogenic impact on the development of hazardous geological processes in the mountainous regions of the Northern Caucasus in the current century. Technogenic impact is determined by the stability of rock formations that make up the Krasnodar Territory, Kabardino-Balkaria, and North Ossetia relative to the impacts of other forces. It is also noted that the activity of hazardous geological processes is largely determined by the interaction of climatic conditions, which determine their speed, and technogenesis. Examples of problematic territories of the North Caucasus are given. To assess climatic changes and major catastrophes, a typology of atmospheric circulation in the Northern Hemisphere was developed under the leadership of B.L. Dzerdzeevsky. Typification materials from the period between 1899 and 2018 are posted in the public domain, at www.atmospheric-circulation.ru. The largest catastrophes, in which landslides and mudflows became more active, and the interaction of natural and man-made factors in these disasters are considered.Hazardous geological processes can disrupt the sustainable development of individual regions with their negative impact on the environment. The assessment of their danger is therefore of special current relevance. The article considers the possibility of predicting catastrophes associated with these processes. Long-term forecasts of landslides, mudflows and other processes continue to be important. The methodology of such forecasting was previously developed in sufficient detail. The greatest importance is assigned to operational forecasts that will make it possible to warn of possible danger hours or even days ahead.
