Однако употребление фальсифицированных мясных продуктов может нанести ущерб здоровью человека, а также нарушить возможные ограничения, связанные с вероисповеданием. Для определения видового состава мясной продукции и измерений содержания примесей применяются методы анализа нуклеиновых кислот, требующие использования стандартных образцов. Утверждение в 2024 году Государственного первичного эталона единицы числа копий последовательности ДНК ГЭТ ­220–2024 позволило приступить к разработке стандартных образцов, аттестуемых по отношению числа копий видоспецифических последовательностей ДНК. Были приготовлены и аттестованы стандартные образцы, представляющие растворы смесей геномной ДНК, выделенной из мяса свиньи, курицы и крупного рогатого скота. На основании проведенных испытаний в конце 2024 года были утверждены типы стандартных образцов состава ДНК курицы в матрице ДНК крупного рогатого скота (ГСО ­12743-2024 комплект ДНК-Gallus-ВНИИМ) и стандартных образцов состава ДНК свиньи в матрице ДНК крупного рогатого скота (ГСО ­12744-2024 комплект ДНК-Sus-ВНИИМ). Данные стандартные образцы содержания видоспецифической ДНК замещают существующие аналоги стандартных образцов иностранного производства и обеспечивают метрологическую прослеживаемость выполняемых в Российской Федерации измерений в области пищевой промышленности к Государственному первичному эталону единицы числа копий последовательности ДНК ГЭТ ­220.</p></abstract><trans-abstract xml:lang="en"><p>Meat and meat products are one of the key elements of nutrition worldwide. At the same time, food adulteration is a serious problem for both medical and religious reasons. To determine the species composition of meat products and measure the content of impurities, nucleic acid analysis methods are used, which require application of reference materials. The approval in 2024 of the State primary standard for the DNA sequence copies number GET 220–2024 made it possible to begin development of reference materials certified for the species-specific DNA sequences copy number ratio. Reference materials representing solutions of mixtures of genomic DNA isolated from pork, chicken, and cattle were prepared and certified. Based on the trials conducted, at the end of 2024, the types of RM for chicken DNA composition in a cattle DNA matrix (GSO 12743-2024 DNA-Gallus-VNIIM set) and RM for pig DNA composition in a cattle DNA matrix (GSO 12744-2024 DNA-Sus-VNIIM set) were approved at the end of 2024. These reference materials of species-specific DNA content replace existing foreign-made RM analogues and ensure the metrological traceability of measurements performed in the Russian Federation in the food industry to the state primary standard GET 220.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стандартные образцы</kwd><kwd>видовой состав</kwd><kwd>мясная продукция</kwd><kwd>видоспецифические последовательности ДНК</kwd><kwd>отношение числа копий последовательностей ДНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reference materials</kwd><kwd>species composition</kwd><kwd>meat products</kwd><kwd>species-specific DNA sequences</kwd><kwd>DNA sequences copy number ratio</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках ГК № 120-38/2023 от 17.05.2023 на выполнение опытно-конструкторской работы по теме «Разработка и выпуск новых комплексов стандартных образцов имер для обеспечения единства измерений по приоритетным направлениям в целях технологического суверенитета Российской Федерации» (шифр ОКР «Суверенитет»).</funding-statement><funding-statement xml:lang="en">The work was carried out within the Government Contract No. 120-38/2023 dated 17.05.2023 for the implementation of experimental design work on the topic «Development and production of new complexes of reference standards and measures to ensure the uniformity of measurements in the priority areas for the purposes of securing technological sovereignty of the Russian Federation» (code of the Development Work “SUVERENITET”).</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">Lysine supply is a critical factor in achieving sustainable global protein economy / I.
