Целью данных исследований являлось изучение химико-технологических показателей плодов новых сортов яблони белорусской селекции, устойчивых к парше, выделившихся при агробиологическом изучении. Сложное генетическое происхождение новых сортов во многом определяет биохимический состав плодов. Новые сорта яблони отличаются повышенным содержанием растворимых сухих веществ (12,6-13,7 %); по титруемой кислотности (0,70-0,94 %) превышают стандартный сорт Весялина — 0,56 %, а также по сумме сахаров (9,85-11,40 %). Содержание пектиновых веществ в плодах изученных сортов колебалось от 0,76 (Зорка) до 1,31 % (Нававіта). Наибольшим содержанием пектиновых веществ выделяются сорта Сакавіта и Нававіта — 1,30 и 1,31 % соответственно, аскорбиновой кислоты — сорта Красавіта (7,1 мг/100 г) и Весялина (15,17 мг/100 г), а содержанием фенольных соединений — сорт Нававіта (211,1 мг/100 г). Установлено, что плоды новых сортов яблони Зорка, Красавіта, Нававіта и Сакавіта пригодны для выработки сока натурального прямого отжима, нектара без мякоти, нектара с мякотью, плодов протертых с сахаром стерилизованных, плодов протертых с сахаром замороженных.</p></abstract><trans-abstract xml:lang="en"><p>The object of the research was new Belarusian apple varieties Zorka, Krasavіta, Navavіta and Sakavіta, selected from the hybrid fund, obtained as result of many-stage crossing of apple varieties (Malus domestica Borkh.) of various geographical origin (local, American, Western European) with the fourth and fifth generations of profusely blossoming wild apple (M. × floribunda Sieb.), which is carrier of scab resistance Rvi6 gene. The aim of these studies was to study the chemical and technological composition of fruits of new Belarusian apple varieties that are resistant to scab, released during agro biological research. The biochemical composition of the fruit depends mainly on the complex genetic origin of new varieties. New apple varieties differ by a higher content of soluble solids (12.6-13.7 %), titrated acidity (0.70-0.94 %), they exceed the standard variety Vesyalina (0.56 %), as well as the amount of sugars (9.85-11.40 %). The content of pectic substances in the fruits of the studied varieties ranged from 0.76 (Zorka) to 1.31 % (Navavіta). The highest content of pectin substances are the varieties Sakavіta and Navavіta — 1.30 and 1.31 %, respectively. The varieties Krasavіta (7.1 mg / 100 g) and Vesyalina (15.17 mg/ 100 g) are characterized by highest content of ascorbic acid, and the variety Navavita (211.1 mg / 100 g) is characterized by highest content of phenolic compounds. It established that the fruits of the new apple varieties Zorka, Krasavіta, Navavіta and Sakavіta are suitable for producing juice of natural direct extraction, nectar without pulp, nectar with pulp, sterilized fruits rubbed with sugar, frozen.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>яблоня</kwd><kwd>сорта</kwd><kwd>продукты переработки</kwd><kwd>химический состав</kwd><kwd>Беларусь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>apple</kwd><kwd>varieties</kwd><kwd>processed products</kwd><kwd>chemical composition</kwd><kwd>Belarus</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Материалы печатаются в рамках мероприятия, проводимого при финансовой поддержке Российского фонда фундаментальных исследований, проект № 19-016-20005.</funding-statement><funding-statement xml:lang="en">Materials are published in the framework of the event, held with the financial support of the Russian Foundation for Fundamental Research, project No.19-016-20005.</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">Метлицкий О.
