Для проведения исследований по обнаружению внутренних дефектов были подготовлены три группы клубней картофеля, включающие в себя кондиционные и некондиционные образцы. Общая выборка клубней картофеля составила 38 образцов. Для создания скрытых дефектов в виде потемнений мякоти клубней был использован метод регулируемого удара о твердую поверхность. Описана методика проведения экспериментальных исследований и режимные параметры ЯМР. Исследуемые клубни картофеля помещались в сильное магнитное поле напряженностью 1,5 Тл. В качестве основного метода анализа полученных результатов был выбран анализ Т2 изображений, так как именно при таком способе можно отследить один из важнейших показателей обнаружения внутренних повреждений клубней картофеля – недостаток воды в поврежденных участках мякоти. Дефектные зоны на изображениях клубней имеют темный цвет, в то время как здоровая ткань – светлый. Проведен сравнительный анализ изображений, полученных при помощи ЯМР, и натурных снимков клубней в разрезе, что позволило с высокой точностью определить совпадение местоположения дефектов, выявленных неинвазивным методом с их реальным расположением в клубне. Работа продемонстрировала ценность ЯМР для детального неинвазивного способа определения скрытых дефектов клубней картофеля на автоматических сортировальных машинах.</p></abstract><trans-abstract xml:lang="en"><p>The results of experimental studies are presented, determining the internal defects of potato tubers using nuclear magnetic resonance (NMR) method, which provide access to information about the state and distribution of water at the cellular and tissue levels. In order to carry out internal defect detection studies, three groups of potato tubers were prepared, comprising conditioned and unconditioned samples. The total sampling of potato tubers amounted to 38 samples. To create hidden defects in the form of darkening of tuber pulp, the method of controlled impact on a hard surface was used. Methodology for conducting experimental studies and time parameters of NMR are described. The studied potato tubers were placed in a strong magnetic field with intensity of 1.5 Tesla. Analysis of T2 images was chosen as the main method for analyzing the obtained results, since this method allows to trace one of the most important indicators of detecting internal damage of potato tubers – lack of water in the damaged areas of the pulp. The damaged areas in the images of tubers have a dark color, while the healthy tissue is light. A comparative analysis of images obtained using NMR and full-scale images of tubers’ section was carried out, allowing to determine with high accuracy the coincidence of location of defects detected by non-invasive method with their actual location in the tuber.  The study showed the value of NMR for a detailed non-invasive method for determining hidden defects in potato tubers on automatic grading machines.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>клубни картофеля</kwd><kwd>сортировка</kwd><kwd>внутренние дефекты</kwd><kwd>ядерный магнитный резонанс</kwd><kwd>Т2 релаксация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>potato tubers</kwd><kwd>sorting</kwd><kwd>internal defects</kwd><kwd>nuclear magnetic resonance</kwd><kwd>T2 relaxation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнялась в рамках ГПНИ «Сельскохозяйственные технологии и продовольственная безопасность» на 2021–2025 годы, подпрограмма «Механизация агропроцессов и “точное” сельское хозяйство»</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the State Program of Scientific Research “Agricultural Technologies and Food Security” for 2021–2025, subprogram “Mechanization of Agricultural Processes and Precision Agriculture”</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">Об объявлении 2024 года Годом качества [Электронный ресурс]: Указ Президента Респ.
