The purpose of this study was to determine the content of carotenoids in the fruits of some representatives of Sorbus genus from the collection of the South Ural Botanical Garden-Institute. For the quantitative analysis, the fruits of the rowan trees were collected in the phase of full ripening and dried to an air-dry state. Sorbus aucuparia L. was used as an object of comparison as the official pharmacopoeias species. Qualitative detection of carotenoids was performed by thin layer chromatography, quantitative determination - spectrophotometrically.It was found that the highest content of carotenoids is characterized by a sort of hybrid origin × Crataegosorbus miczurinii “Garnet” – 46.41 mg/% and a natural hybrid Sorbocotoneaster pozdnijkovii – 42.64 mg /%. The minimum content of this group of substances is noted in the raw material of Sorbus frutescens (0.86 mg/%) with white fruits. This fact is confirmed by the presence of plant pigments – carotenoids, in fruits that have a yellow-orange-red color. The local Sorbus aucuparia had a low carotenoid content (11.24 mg/%).The study, with a certain degree of reliability, suggests the presence of carotenoids in the fruits of the rowan trees studied and allows us to recommend them as a promising source of raw materials for the production of vitamin-active drugs and food additives. The studied taxons × Crataegosorbus miczurinii and × Sorbocotoneaster pozdnijkovii are characterized by high introduction resistance under the conditions of the Bashkir Cis-Urals. In the future, it is intended to continue the study of other members of the Sorbus genus for the presence of pharmacopoeias properties.

The introduction of fruit plants into a culture enriches the diversity of the species composition of the regional flora and at the same time creates an opportunity for expansion of the plant raw material base for the needs of the food industry, inclusion in a full-fledged functional nutrition of the population. Among the fruit plants of the Dniprovsk region, every year, more attention should be paid to introduced low-frequency non-traditional fruit species, in which the fruits, leaves, stems and other parts have high nutritional value and are the source of physiologically active compounds that have anti-cancer, antibacterial and anti-inflammatory properties, carry cardio protective, antihypertensive, anti-diabetic effects, stimulate the central nervous system, etc., and can contribute to the prevention and treatment of many diseases.   Antioxidants additives in the raw materials and finished products ensures their prevention damage, reduce losses, increase shelf life and production of high quality products which keep for a long time characteristics inherent fresh, complete products. Preservation, restoration and introduction to the culture of any species depends primarily on its ability to multiply seed and vegetative methods. A comparative analysis of the fruit and seed ability of Berberis L. representatives grown in the botanical garden of Oles Gonchar’  Dniprovsky National University was carried out. The use of integrated research methods made it possible to carry out an integrated assessment of the regenerative capacity of the investigated representatives of the Berberis L. and to establish their biological ability to seed propagation depending on the seed quality of the seeds. The seeds length varied from 4.5 mm (B. canadensis) to 5.2 mm (B. declinata, B. amurensis), width was from 1.8 mm (B. amurensis, B. vulgares) to 2.1 mm ( B. coreana). The weight of 1000 seeds, which, depending on their size and completeness, amounted to an average of 10.16 grams. Largest weight 1000 pcs. seed is marked in B. coreana. As a result of the total antioxidant ability of the fruits, the species examined can be arranged in the following order:  B. koreana > B. x declinata > B. vulgaris > B. amurensis > B. canadensis. When comparing total antioxidant capacity level of the plants, the highest indices were characteristic for B. koreana and B. x declinata fruits, which exceeded the values of other species in 1.7-1.9 times. The relatively low antioxidants concentration in B. amurensis fruits is offset by a greater weight of the fruits of this species.  In order to enrich the range of ornamental and fruit plants, it is expedient to introduce into production of new crops and to expand the species diversity of Berberis L. representatives. Barberry reproduction process depends on many factors related to the environment. All investigated representatives of the Berberis L. are promising for further use in the planting system and as fruit plants that can be included in the functional nutrition of the population and use in the food industry in the conditions of the Steppe Prydniprovya.

Abstract Lonicera caerulea L., also known as honeysuckle berries, are rich in biologically active compounds, which makes them a valuable raw material for the development of functional foods. The objects of the research were three honeysuckle cultivars (‘Zoluška’, ‘Siņaja Ptica’, ‘Goluboje Vereteno’), four genotypes (No 2A; No 3; No 5; No 8) and kefir, enriched with various amounts (3–10%) of fruit puree. Physical and chemical analyses to determine the qualitative indicators of raw materials and products were performed. The degree of liking of kefir was assessed using sensory analysis: hedonic and line scales. The results obtained showed that among the cultivars the highest content of anthocyanins (1103.5 mg·100 g−1), total phenols (693.3 mg·100 g−1), flavonoids (753.9 mg·100 g−1), and tannins (1.6 mg·100 g−1), were found in ‘Siņaja Ptica’ berries, while among the genotypes, berries of No 8 had the highest concentration of the aforesaid compounds. Both samples also showed the highest antiradical activity: ABTS+• on average by 71.7% and DPPH− by 43.7%. According to the sensory evaluation, kefir with 10% honeysuckle puree was rated the highest. Honeysuckle berries could be used as a promising source of natural anti-oxidants in future research aimed at developing different new products that could meet consumer expectations.

Among fruit crops, Rowan is one of the most winter-hardy. In Russia, the predominant varieties are those derived from Sorbus aucuparia. Rowan fruits are used in fresh and dried form, they are valuable in food, dietary, and medicinal terms. The objects of this study were 7 Rowan varieties in the exposition «Wild fruit plants» of the Botanical garden-Institute of Volga State University of Technology (Yoshkar-Ola, Mari El Republic). The research was conducted in 2014–2019. The fruits were collected in the mass maturation phase and weighed in 3 samples of 100 pieces. The yield of air-dry fruits, expressed as a percentage, was obtained by the ratio of the mass of dried fruits to the mass of freshly harvested ones. It was found that the varieties ‘Alaya Krupnaya’, ‘Titan’, ‘Granatnaya’, and ‘Burka’ are characterized by large fruits. ‘Desertnaya Michurina’, ‘Nevezhinskaya’, and ‘Doch Kubovoy’ are small-fruited varieties. The most favorable for fruiting of most varieties were 2016 and 2019 with dry conditions of the growing season. Excessively moistened conditions in 2017 negatively affected the formation of Rowan fruits. The yield of air-dry raw materials was inversely correlated with the weight of fruits. The obtained data can be used in the organization of plantation cultivation of Rowan varieties in the conditions of the Volga-Vyatka region.

The leading direction in the field of nutrition is the creation of a range of products that contribute to improving health when they are used daily in the diet. The urgency of studying bovine colostrum-colostrum, which is an immune-modeling animal raw material, has been substantiated. Colostrum is a natural source of all the ingredients needed to build immunity. Biologically active substances contained in cow colostrum contribute to: restoration of immunity; restoration of the intestines and stomach; strengthening the nervous system; renewal of brain cells; improving emotional tone and mood; increasing vitality and performance; slowing down the aging process; protection against diseases of the intestines and stomach, cardiovascular system, respiratory tract, diabetes, allergies, osteoporosis and a number of other diseases. Colostrum contains a minimum of 37 immune factors and 8 growth factors that help the body fight disease and promote good health and longevity. The classes of immunoglobulins contained in colostrum, which represent the bulk of whey proteins, have been studied. Colostrum is a limited source of raw materials, its production period is short, there are many opportunities for industrial use, but due to the small amount of raw materials, the market remains undeveloped, with the exception of food additives. Taking into account the extensive therapeutic and medicinal properties of colostrum, its unique composition and properties, its composition and physicochemical properties were investigated, the fractionation parameters were determined using various systems. To process the experimental studies, the STATISTICA 12 software package was used. To obtain the regression equation, the matrix data were processed using the Microsoft Excel 2010 software package. The analysis of the data obtained indicates the possibility and prospects of using colostroma in food production technology.

Обоснована гидролизная высокотемпературная переработка вторичного копченого рыбного сырья, позволяющая глубоко деструктировать рыбную массу. С целью установления рациональных значений варьировали показатели основных параметров гидролиза: температуру сырья, температуру в рубашке автоклава, продолжительность термогидролиза, скорость перемешивания сырья. Были исследованы процессы: с предварительным ферментированием протеолитическим ферментом алкалазой (0,25 к массе системы) и без него, с предварительным удалением жира из рыбной массы и без обезжиривания. Для проведения исследований вторичное сырье шпротного производства головы копченой кильки жирностью 13,8 14,5 18,8 и 24,5 после измельчения смешивали с водой в соотношении 1 : 1 и автоклавировали под давлением 0,150,2 кгс/см2. В экспериментах с предварительным отделением жира копченое сырье смешивали с водой температурой 80С, выдерживали при этой температуре, после чего смесь центрифугировали и из нее декантированием извлекали жир. Установлено, что рациональным способом гидролиза копченого коллагенсодержащего высокоминерализованного рыбного сырья при получении пищевых добавок является комбинированный способ, предусматривающий предварительное отделение жира и предварительное ферментирование алкалазой, с последующим термогидролизом в автоклаве при температуре 130С в течение 60 мин при скорости вращения мешалки 50 об/мин. Выход сублимированного протеинового гидролизата составляет 8,7 при содержании в нем, : протеина 82,7 жира 2,0 минеральных веществ 0,6. Степень экстракции белка в гидролизат составляет 48,0 от его первоначального содержания в сырье. Выход осадочной фракции белковоминеральножирового продукта составляет 35,7 при содержании в нем, : протеина 54,5 жира 18,1 минеральных веществ 23,6. Степень извлечения белка (высокомолекулярных нерастворимых коллагеновых волокон) в осадочную фракцию составляет 45,3. Полученные фракции в сухом (протеиновая) и жидком (белковожировая и жировая) состоянии апробированы в качестве пищевых добавок в составе рецептур капсулированных биологически активных добавок к пище, соусов, закусочных снеков, рыбных пресервов и консервов, шпротного паштета. Hydrolytic hightemperature processing of secondary smoked fish raw materials, which allows to deeply destruct the fish mass, is justified. Indicators of the main parameters of hydrolysis the temperature of the raw material, the temperature in the shirt of the autoclave, the duration of thermal hydrolysis, the mixing rate of raw materials were varied with the aim of establishing rational values. Processes with prefermentation with proteolytic enzyme alcalise (0,25 to the weight of the system) and without him, with preliminary removal of fat from the fish mass and without degreasing were investigated. For research, secondary raw materials of sprat production smoked sprat heads with a fat content of 13,8 14,5 18,8 and 24,5 after grinding were mixed with water in a ratio of 1 : 1 and autoclaved under a pressure of 0,150,2 kgf/cm2. In experiments with the preliminary separation of fat smoked raw material is mixed with water at a temperature of 80C, kept at this temperature, after which the mixture is centrifuged and the fat is extracted from it by decanting. It is established that the rational method of hydrolysis of smoked collagencontaining highly mineralized fish raw materials in the preparation of food additives is a combined method, providing for the preliminary separation of fat and preliminary fermentation with alcalase, followed by thermohydrolysis in an autoclave at a temperature of 130C for 60 min at a speed of rotation of the stirrer 50 rpm. The yield of freezedried protein hydrolysate is 8,7 with the content therein, : protein 82,7 fat 2,0 minerals 0,6. The degree of protein extraction in the hydrolysate is 48,0 of its initial content in the raw material. The yield of the sedimentary fraction of the proteinmineralfat product is 35,7 with the content in it, : protein 54,5 fat 18,1 minerals 23,6. The degree of protein extraction (highmolecular insoluble collagen fibers) in the sedimentary fraction is 45,3. The obtained fractions in the dry (protein) and liquid (fat) state were tested as food additives in the formulations of encapsulated biologically active food additives, sauces, snacks, fish preserves and canned food, sprat paste.
