Впервые разработана и представлена комплексная калибровочная модель для экспресс-определения основного вещества методом инфракрасной спектроскопии в ближней области (ИК) в кормовых аминокислотах, используемых в производстве комбикормов. Принцип исследования основан на уравнении Фурье для спектроскопии. В работе был применен метод Фурье в инфракрасной области (FTIR, FT-NIRS). Данные, полученные с помощью калибровочных моделей, были подтверждены с помощью высокоэффективной жидкостной хроматографии. Результаты. Прогнозы FT-NIR хорошо согласовались с данными хроматографии и имели значения прогностического отклонения (RPD) &gt;1,3 во всех случаях. Полученные результаты указывают на то, что ИК-спектроскопия FT-NIR может быть использована в качестве простого и быстрого инструмента для контроля аминокислот. В ходе работы были получены экспериментальные подтверждения ранее известных фактов — возможность визуального разделения спектров не только фальсификатов аминокислот, но и возможность разделения по L- и DL-оптическим изомерам. В работе показано, что расхождения между значениями, полученными классическим методом «мокрой химии», и значениями, полученными по построенным калибровочным моделям, не выходят за пределы воспроизводимости арбитражных методов. Была использована прогностическая модель, основанная на элементах информационного потока с применением OPUS/QUANT2 программного пакета для многомерной калибровки и построения калибровочных моделей для аминокислот. Данный хемометрический анализ доказал принципиальную возможность определения аминокислот в продукте.Показано, что использование информационных каналов открывает возможности для применения многих алгоритмов хемометрики, включая предобработку данных и построение прогностических моделей.</p></abstract><trans-abstract xml:lang="en"><p>Methods. For the first time, a comprehensive calibration model has been developed and presented for the rapid determination of basic near-infrared spectroscopy (IR) methods in feed amino acids, with application in the production of animal feed. The research principle is based on the Fourier equation for spectroscopy. In this work, Fourier methods in the Italian region (FTIR, FT-NIRS) were applied. The data obtained from the calibration models were confirmed using high-performance liquid chromatography. FT-NIR predictions agreed well with the chromatography data and had predictive deviation (RPD) values &gt;1.3 in all cases.Results. The results indicate that FT-NIR spectroscopy can be used as a simple and rapid tool for monitoring amino acids. In the course of the work, experimental confirmation of previously known facts was obtained — the possibility of visual separation of the spectra of not only counterfeit amino acids, but also the possibility of separation by L- and DL-optical isomers. The work shows that the discrepancies between the values obtained by the classical “wet chemistry” method and the values obtained from the constructed calibration models do not exceed the reproducibility limits of arbitration methods. A predictive model was used based on information flow elements using the OPUS/QUANT2 software package for multivariate calibration and construction of calibration models for amino acids. This chemometric analysis proved the fundamental possibility of determining amino acids in the product. It has been shown that the use of information channels opens up opportunities for the use of many chemometrics algorithms, including data preprocessing and the construction of predictive models.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инфракрасная спектроскопия</kwd><kwd>калибровки</kwd><kwd>чистые формы аминокислот</kwd><kwd>хемометрия</kwd><kwd>корма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>infrared spectroscopy</kwd><kwd>calibrations</kwd><kwd>amino acids</kwd><kwd>animal feeding</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование было поддержано Министерством науки и высшего  образования Российской Федерации в рамках реализации специальной  части гранта Программы стратегического академического лидерства  «Приоритет 2030» для развития Российского государственного аграрного  университета — МСХА им.
