Фунгициды на основе каптана имеют широкое применение, вследствие чего вещество входит в первую сотню пестицидов, наиболее часто выявляемых в пищевой продукции разных стран. Каптан гидролитически нестабилен и быстро деградирует до метаболита 1,2,3,6-тетрагидрофталимида (THPI), имеет тенденцию разлагаться на различных этапах анализа, что обосновало потребность в проведении специальных экспериментов.</p><p>Цель работы — экспериментальное исследование для выявления потенциальных рисков получения некорректных аналитических результатов при определении фактического содержания каптана и THPI в пищевой продукции для оценки её безопасности. Обоснование оптимальных подходов к процедуре анализа и разработка методики контроля содержания каптана и его метаболита тетрагидрофталимида в плодоовощной и соковой продукции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для идентификации и количественного определения веществ использован метод высокоэффективной жидкостной хроматографии с тройным квадрупольным масс-детектором (ВЭЖХ-МС/МС). Для извлечения аналитов из гомогенизированного образца применяли ацетонитрил, содержащий 0,1% муравьиной кислоты. Аликвоту экстракта очищали вымораживанием при температуре минус 18 °С.</p></sec><sec><title>Результаты</title><p>Результаты. Скорость трансформации каптана зависит от рН среды, с которой он находится в контакте. В образцах, прошедших пробоподготовку (экстракция подкислённым ацетонитрилом) сразу после внесения (нулевой день), разложения каптана не зафиксировано, что объяснятся стабилизацией кислотой. Наибольшая устойчивость вещества наблюдается в кислых продуктах (лимон, рН = 2,0). При необходимости хранения измельчённого образца с низкой кислотностью для максимальной сохранности каптана до анализа рекомендуется понизить рН введением муравьиной кислоты.</p></sec><sec><title>Ограничение исследования</title><p>Ограничение исследования. В исследовании не рассматривалась пищевая продукция с низким содержанием воды.</p></sec><sec><title>Заключение</title><p>Заключение. Показано, что для корректной оценки безопасности пищевой продукции необходимо количественное определение каптана совместно с его метаболитом THPI. Экспериментально обосновано, что понижение рН и температуры при подготовке и хранении проб, экстрактов позволяет сохранить каптан в пробе. Разработана методика определения остаточных количеств каптана и его метаболита тетрагидрофталимида в плодоовощной и соковой продукции методом ВЭЖХ-МС/МС в диапазоне 0,01–50 мг/кг.</p><p>Соблюдение этических стандартов.

Due to the widespread use of captan-based fungicides, the substance is among the top of 100 pesticides most frequently detected in food products worldwide. Captan is hydrolytically unstable and rapidly degrades to the metabolite 1,2,3,6-tetrahydrophthalimide (THPI). The substance tends to degrade at various stages of analysis, which justified the need for special experiments.</p></sec><sec><title>Purpose of the work</title><p>Purpose of the work. Conducting experimental studies to assess the potential risks of obtaining incorrect analytical results on the actual content of captan and THPI in food products when assessing its safety to substantiate optimal approaches to the analysis procedure and develop a methodology for controlling the content of captan and its metabolite tetrahydrophthalimide in fruit, vegetable, and juice products.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. For the identification and quantitative determination of substances, the method of high performance liquid chromatography with a triple quadrupole mass detector (HPLC-MS/MS) was used. To extract analytes from a homogenized sample, acetonitrile containing 0.1% formic acid was used. An aliquot of the extract was purified by freezing at minus 18 °C.</p></sec><sec><title>Results</title><p>Results. In the studied samples of citrus, the analytes showed stability. Thirty months after storage of samples in deep freezing conditions (temperature not higher than –20 °C), the identified levels of active ingredients of the pesticides imazalil, pyrimethanil, and prochloraz did not change by more than 20% compared to the previously detected concentrations. Insignificant amounts of imidacloprid, thiabendazole and pyriproxyfen, traces of azoxystrobin and trifloxystrobin, detected in the study of samples, were also found in samples after long-term storage.</p></sec><sec><title>Limitation</title><p>Limitation. The study did not look at food products with a low water content.</p></sec><sec><title>Conclusion</title><p>Conclusion. For a correct assessment of food safety, it t has been shown to be necessary to quantify captan together with its metabolite THPI. It has been experimentally substantiated that lowering the pH and temperature during the preparation and storage of samples and extracts makes it possible to retain captan in the sample. A procedure has been developed for determining the residual amounts of captan and its metabolite tetrahydrophthalimide in fruit, vegetable, and juice products by HPLC-MS/MS in the range of 0.01–50 mg/kg.</p><p>Compliance with ethical standards. The study does not require a biomedical ethics committee opinion.</p></sec><sec><title>Contribution</title><p>Contribution:Kuz’min S.V. — the concept and design of the study;Fedorova N.E. — the concept and design of the study, writing the text, editing;Dobrev S.D. — the concept and design of the study, collection and processing of the material, statistical analysis;Ivchenkova А.А. — collection and processing of the material, statistical analysis, writing the text, editing.All authors are responsible for the integrity of all parts of the manuscript and approval of the manuscript final version</p></sec><sec><title>Conflict of interest</title><p>Conflict of interest.
