One of the promising varieties for the production of high-quality sparkling, dessert and liquor wines is the technical variety of pink muscat grapes. The aim of this work is to study the agrobiological and technological features of promising clones of the Pink Muscat variety. The object of study was two clones of the Pink Muscat variety - № 21-2-3 and № 53-10-2, growing on the clone test site (№ 509), the Gurzuf branch of the State Unitary Enterprise of the Republic of Kazakhstan PJSC Massandra on an area of 0.5 hectares. The article provides a statistical analysis of the quantitative characteristics of clones of the Muscat pink variety for 2018-2019, as well as the physicochemical and organoleptic characteristics of grapes and wine materials from clones of this variety of the 2019 crop. It was established that the fruiting coefficients (0.6- 0.65) in the studied clones are at the control level and are characterized as average. The mass of a bunch of clones exceeds the control by 1.4-2.15 times, reaching 322-494 g. The actual yield from the bush is 4.9-6.8 kg, exceeding the control by 2.13-2.96 times. According to the indicator, the shoot productivity in the wet mass of a bunch of 209.3-296.4 g /clone shoot is 1.68-2.38 times higher than the control. Wine materials made from clones of the Muscat pink grape varieties possess the amount of phenolic substances (within 506 mg /dm3 ) and the concentration of the reduced extract (23-25 g/dm3 ) at the control level, which gives grounds for further study of the selected clones in the technology of various types of wines . Tasting evaluation of wine materials also showed their high quality, not inferior to the wine material of the control sample.

In order to increase the production of original and recognizable sparkling wines, base wines from autochthonous grape varieties can be used for their preparation. Based on the studied basic and advanced physicochemical and organoleptic characteristics, it was concluded about the possibility of using autochthonous grape varieties - ‘Makhrovatchic’, ‘Tsimlyanskii Belyi’, ‘Tsimladar’, ‘Kefesiya’, ‘Kokur Krasnyi’ and ‘Chernyi Krymskii’ - for production of high-quality sparkling wines. The relationships of the phenolic complex components with the parameters of sparkling wines, characterizing their appearance, was established, so for white sparkling wines - mass concentration of polymeric forms of phenolic substances with yellowness index (r = 0.925); for red ones - mass concentration of monomeric forms of phenolic compounds and mass concentration of coloring agents with the index of color intensity r = 0.580 and r = 0.786, respectively; for white and red sparkling wines - mass concentration of polymeric forms of phenolic substances with a maximum foam volume (r = 0.628). It was also noted as a positive factor that all samples accumulated a sufficient amount of the bound CO2 (not less than 8% of the total bottle content.

Климатические условия на большей части территории Российской Федерации не позволяют выращивать виноград в открытом грунте, поэтому его завозят из южных районов страны. Производство виноградных напитков обычно сосредоточено в местах выращивания винограда, так как доставка готовой продукции в северные регионы сопряжена со значительными финансовыми затратами. В Республике Дагестан выращивают около 30% винограда в масштабах всей страны, а площадь плодоносящих виноградников занимает более 20 тыс. га. Возникла необходимость переработать виноград таким образом, чтобы полуфабрикат для изготовления напитков выдерживал длительные сроки хранения и транспортировку, отличался высоким качеством и имел небольшую массу. Разработана технология получения виноградных криопорошков, которые можно использовать в качестве пищевых добавок, для изготовления восстановленных соков и напитков. Целью исследования было создание инновационной технологии производства криопорошков для получения безалкогольных напитков. Объектом исследования стал виноград дагестанских технических, столовых и изюмных сортов. Алгоритм получения криопорошков соответствовал предложенной автором схеме: доставка винограда, отделение гребней, инспекция, мойка, дробление, замораживание жидким азотом, обезвоживание в вакуумной СВЧ-установке, криоизмельчение и фасовка. При выполнении работы определяли качественный состав сырья и криопорошков с использованием аналитических приборов и лабораторного оборудования кафедры технологии продуктов питания и учреждений Дагестанского научного Центра РАН. Определен химический состав криопорошков, полученных из винограда, выращенного в горно-долинной зоне Дагестана. Приведены физико-химические показатели напитка из криопорошка винограда. Органолептические показатели изготовленных виноградных напитков подтвердили их высокие качественные показатели. Climatic conditions in most of the Russian Federation do not allow growing grapes in the open field, therefore they are imported from the southern regions of the country. The production of grape drinks is usually concentrated in places where grapes are grown, since the delivery of finished products to the northern regions is associated with significant financial costs. Winegrowers of the Republic of Dagestan grow about 30% of grapes throughout the country, and the area of fruit-bearing vineyards occupies more than 20 thousand hectares. There was a problem to process grapes in such a way that the semi-finished product for the production of drinks withstands long storage and transportation periods, is of high quality and has a small weight. A technology has been developed for producing grape cryopowders, which can be used as food additives, for the production of reconstituted juices and drinks. The aim of the study was to create an innovative technology for the production of cryopowders for the production of soft drinks. The objects of the study were Dagestan common and raisin grapes. The algorithm for obtaining cryopowders corresponded to the scheme proposed by the author: delivery of grapes, separation of ridges, inspection, washing, crushing, freezing with liquid nitrogen, dehydration in a vacuum microwave unit, cryo-grinding and packaging. When performing the work, the qualitative composition of raw materials and cryopowders was determined using analytical instruments and laboratory equipment of the Department of Food Technology and institutions of the Dagestan Scientific Center of the Russian Academy of Sciences. The chemical composition of cryopowders obtained from grapes grown in the mountain-valley zone of Dagestan has been determined. The physical and chemical parameters of a wine drink made from grape cryopowder are given. The organoleptic characteristics of the produced wine drinks confirmed their high quality indicators.

Представлены результаты исследований физико-химических и органолептических показателей крымских и донских аборигенных красных сортов в системе «виноград-виноматериал» из Ампелографической коллекции института «Магарач» (с. Вилино Бахчисарайского района). Установлено, что активность окислительных ферментов (пероксидазы и монофенол-монооксигеназы) практически во всех сортах была низкой или отсутствовала. Технологический запас фенольных веществ в изученных сортах винограда находился в достаточно широком диапазоне - от 2139 до 3865 мг/дм, в т.ч. технологический запас красящих веществ - от 149 (Кокур красный) до 1232 мг/дм (Безымянный). Определено, что из сорта винограда Кефесия получаются виноматериалы с хорошими пенистыми свойствами (Vболее 800 см). Установлено, что соотношение массовых концентраций винной и яблочной кислот было оптимальным (более 1) во всех исследуемых сортах. Высокими дегустационными оценками отмечены сорта Цимладар, Безымянный и Солнечная Долина 58. По совокупности проведенных исследований основных и дополнительных физико-химических и органолептических показателей в системе «виноград-виноматериал» и технологической оценки крымских и донских аборигенных красных сортов винограда, произрастающих в Ампелографической коллекции института «Магарач», можно заключить, что для производства игристых вин представляют интерес виноматериалы из аборигенных красных сортов винограда Кефесия, Солнечная Долина 58, Цимладар, Безымянный. The article presents the results of studies of the physical-chemical and organoleptic characteristics of native red grape varieties of Crimea and Don in the system “grapes-wine material” from the Ampelographic collection of Magarach Institute (village Vilino, Bakhchisaray district). It was established that the activity of oxidizing enzymes (peroxidase and monophenol-monooxygenase) was low or absent in almost all varieties. The technological stock of phenolic substances in the studied grape varieties was in a rather wide range - from 2139 to 3865 mg/dm, including the technological reserve of coloring substances - from 149 (‘Kokur Krasnyi’) to 1232 mg/dm (‘Bezymyannyi’). Good foaming capacity (V more than 800 cm) was achieved in wine materials made of ‘Kefesiya’ grape variety. The ratio of mass concentrations of tartaric and malic acids was optimal (more than 1) in all varieties under study. High tasting evaluation gained the varieties ‘Tsimladar’, ‘Bezymyannyi’ and ‘Solnechnaya Dolina 58’. Basing on the combination of studies of essential and additional physical-chemical and organoleptic parameters in the system “grapes-wine material” and on the technological assessment of native red grapes of Crimea and Don that grow in the Ampelographic collection of the Magarach Institute, we can draw the following conclusion: wine materials made of native red grape varieties ‘Kefesiya’, ‘Solnechnaya Dolina 58’, ‘Tsimladar’, ‘Bezymyannyi’ are of interest to the production of sparkling wines.

Возросший интерес к винам из стран, считающихся родиной виноделия (Армения, Грузия, Греция, Румыния), связан со своеобразием ароматов и вкусов, обусловленных местными традиционными сортами винограда. Однако сортовой состав автохтонного винограда, используемый в производстве вин в Армении, весьма ограничен. Нами поставлена цель выявить и изучить перспективность малораспространенных, забытых аборигенных армянских сортов винограда для производства высококачественных вин. Актуальность работы связана с увеличением сырьевых ресурсов виноградовинодельческой отрасли республики. Для исследования были выбраны аборигенные красные сорта Тозот, Кохбени, Арени (контроль) из двух регионов Армении. Опытные виноматериалы были приготовлены в условиях микровиноделия. Двухлетние изучения технохимических показателей и органолептическая оценка опытных образцов выявили перспективность использования красных (Тозот и Кохбени) сортов автохтонного винограда в качестве сырья для производства вин высокого качества в разных регионах Армении. Recent years the increased interest in wines from countries considered to be the birthplace of winemaking (Armenia, Georgia, Greece, Romania) is associated with the uniqueness of aroma and flavor of the local traditional grape varieties. However, the variety assortment of autochthonous grapes used in wine production in Armenia is very limited. Our goal is to find out and study the prospects of less common autochthonous Armenian grape varieties for the high quality wine production. The relevance of this work is associated with the increase in the amount of raw materials of the viticultural and winemaking industry of the Republic. Red autochthonous grape varieties 'Tozot', 'Koghbeni', 'Areni' (as the control) from two regions of Armenia were selected for the research. Experimental base wines were produced in the conditions of microvinification. A two-year research of technochemical indicators and organoleptic assessment of experimental samples revealed the potential of using local red varieties ('Tozot' and 'Koghbeni') as raw materials for the high quality wine production in different regions of Armenia. The research was carried out with the financial support of State Science Committee of the Ministry of Education and Science of the Republic of Armenia within the framework of scientific project No. 18T-2K024.

Проведена сравнительная оценка эффективности антиоксидантного и гепатопротекторного действия пищевых добавок, полученных из выжимки винограда белых сортов по различным технологиям, в экспериментах на лабораторных животных. Установлено, что пищевая добавка «Порошок виноградный» (ПВ), полученная из выжимки винограда белых сортов по разработанной технологии, позволяет, по сравнению с контрольным образцом пищевой добавки, в большей степени снизить в сыворотке крови содержание продуктов перекисного окисления липидов – малонового диальдегида, диеновых коньюгатов и кетодиенов, что свидетельствует о более высокой эффективности антиоксидантного действия ПВ на организм животных, обусловленной большим содержанием микронутриентов с антиоксидантными свойствами. Добавка ПВ проявляет более высокую эффективность гепатопротекторного действия, заключающуюся в значительном снижении уровня активности аланинаминотрансферазы в сыворотке крови, по сравнению с контрольным образцом добавки. Comparative evaluation of the effectiveness of antioxidant and hepatoprotective action of food additives which obtained from grape pomace white varieties for various technologies, was carried out in experiments on laboratory animals. It is established that the food additive “Grape Powder” (GP), obtained from the pomace of white grape varieties by the developed technology, allows, in comparison with the control sample of the food additive, to reduce the content of lipid peroxidation products in the serum to a greater extent – Malon dialdehyde, diene conjugates and ketodienes, which indicates a higher efficiency of antioxidant action of GP on the organism of animals, due to the high content of micronutrients with antioxidant properties. The additive GP shows a higher efficiency of hepatoprotective action, which consists in a significant reduction in the level of alanine aminotransferase activity in the blood serum, compared to the control sample of the additive.
