Виноградные выжимки – побочный продукт винодельческой промышленности – являются источником многих биологически активных веществ с полезными свойствами.Цель работы. Изучение зависимости органолептических и физико-химических показателей экстрактов из виноградных выжимок сортов Каберне, Саперави, Первенец Магарача и Цитронный Магарача от способа обработки (высушивание и замораживание) выжимок перед экстракцией.Методы исследования. Биохимические (кислотность, содержание полифенольных веществ, витамина С, общих и редуцирующих сахаров), товароведные (внешний вид, аромат, вкус, цвет), математический анализ.Результаты исследования. Установлено, что органолептическая оценка экстрактов из выжимок красных сортов винограда была наибольшей у замороженного образца сорта Каберне (средний балл 4,0 против 2,5-3,5 у остальных образцов); у белых сортов винограда органолептическая оценка экстрактов принципиально не различалась. Кислотность экстрактов из выжимок красных сортов винограда (1,8-2,4 %) была в 3…9 раз выше, чем из выжимок белых сортов; при этом в экстрактах из замороженных выжимок кислотность была выше на 0,3-0,6 %. Наибольшее содержание полифенольных веществ было в экстрактах из выжимок сорта Саперави (543,42 мг/100г), наименьшее – из сорта Цитронный Магарача (179,68 мг/100г); сушка выжимок привела к снижению содержания полифенолов на 30,37-44,70 % в зависимости от сорта. Содержание витамина С находилось в диапазоне 2,21-4,80 мг/100г; сушка приводила к снижению этого показателя на 31,58-43,13 % в зависимости от сорта. Массовая доля общих сахаров находилась в диапазоне 2,1-6,3 %, редуцирующих сахаров – в диапазоне 1,5-5,2 % (в сладких выжимках эти показатели – в 2…3 раза выше, чем в сброженных); у трёх сортов из четырёх сушка привела к снижению массовой доли сахаров на 29,17-38,46 %.Заключение. Полученные данные могут быть использованы при разработке технологии производства безалкогольных напитков с использованием виноградных выжимок как источника биологически активных веществ.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Grape pomace is a by-product of the wine industry. It is a source of many biologically active substances with beneficial properties.The goal of the research was to study the dependence of organoleptic and physicochemical parameters of extracts from grape pomace of the Cabernet, Saperavi, Pervenets Magarach and Citronny Magarach varieties on the processing method (drying and freezing) of the pomace before extraction.The research methods included biochemical ones (acidity, content of polyphenolic substances, vitamin C, total and reducing sugars), commodity science methods (appearance, aroma, taste, color), mathematical analysis.The research results. It was found that the organoleptic assessment of extracts from pomace of red grape varieties was the highest for the frozen sample of the Cabernet variety (average score 4.0 versus 2.5-3.5 for the other samples); for white grape varieties, the organoleptic assessment of extracts did not differ fundamentally. The acidity of extracts from the pomace of red grape varieties (1.8-2.4%) was 3-9 times higher than that from the pomace of white varieties; at the same time, the acidity of extracts from frozen pomace was 0.3-0.6% higher. The highest content of polyphenolic substances was found in extracts from the pomace of the Saperavi variety (543.42 mg/100 g), the lowest – from that of the Citronny Magarach variety (179.68 mg/100 g); drying of the pomace led to a decrease in the polyphenol content by 30.37-44.70% depending on the variety. The content of vitamin C was in the range of 2.21-4.80 mg/100 g; drying led to a decrease in this indicator by 31.58-43.13% depending on the variety. The mass fraction of total sugars was in the range of 2.1- 6.3%, reducing sugars - in the range of 1.5-5.2% (in sweet pomace these indicators are 2 ... 3 times higher than in fermented ones); for three varieties out of four, drying led to a decrease in the mass fraction of sugars by 29.17-38.46%. The conclusion. The data obtained can be used in the development of a technology for the production of soft drinks using grape pomace as a source of biologically active substances.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>виноградные выжимки</kwd><kwd>сушка</kwd><kwd>заморозка</kwd><kwd>экстракт</kwd><kwd>органолептические показатели</kwd><kwd>физико-химические показатели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>grape pomace</kwd><kwd>drying</kwd><kwd>freezing</kwd><kwd>extract</kwd><kwd>organoleptic indicators</kwd><kwd>physicochemical indicators</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Кубанского научного фонда в рамках научного проекта № Н-24.1/44.</funding-statement><funding-statement xml:lang="en">The research was carried out with the financial support of the Kuban Science Foundation within the framework of scientific project No. H-24.1/44.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Effects of micronization on dietary fiber composition, physicochemical properties, phenolic compounds, and antioxidant capacity of grape pomace and its dietary fiber concentrate / Bender Ana Betine Beutinger [et al.] // LWT. 2020.
