“…Полученные модели для люпанина и ангустифолина имели очень низкие значения коэффициента детерминации (R насколько существенно отклоняется прогнозируемое значение от истинного. Для калибровочных моделей люпанина, ангустифолина и суммы алкалоидов RPD равнялся 1,17; 1,13 и 1,48; BIAS соответствовал 63,2; 64,9 и -1,45, что свидетельствует о возможности значительного отклонения результатов, полученных с помощью построенной модели, от реальных значений (Efimenko et al, 2015;Efimenko et al, 2016;Efimenko S.G., Efimenko S.K., 2019). Таким образом, полученные модели калибровочных кривых не подходят для изучения содержания хинолизидиновых алкалоидов в муке люпина узколистного, однако характеристики калибровочной модели, полученной для суммы хинолизидиновых алкалоидов, позволяет предположить, что при расширении калибровочной кривой (увеличении количества образцов, включенных в модель) достоверность полученных с ее помощью результатов будет возрастать.…”

“…Модели, полученные для белка и масла, имели достаточно высокий коэффициент детерминации (85,02 и 78,53) с 12 и 11 рангами при многомерном анализе соответственно. RMSEP для них составляла 0,67 и 0,235%, что дает надежную повторяемость полученных результатов; RPD -2,5 и 2,22 соответственно, что говорит об «удовле творительном качестве» построенных калибровочных моделей (Efimenko et al, 2015;Efimenko et al, 2016;Efimenko S.G., Efimenko S.K., 2019); BIAS -0,0728 и -0,0557 соответственно, что подтверждает практически полное совпадение реальных результатов с результатами, полученными с помощью построенных моделей.…”

“…Качественный и ко ли чественный состав хинолизидиновых алкалоидов в ВИР определяется по недавно разработанному методу (Kushnareva et al, 2020). Однако для изучения большого количества образцов семян и муки различных культур применяется спектроскопия в ближней области инфракрасного спектра (БИК) с использованием ИК-анализаторов, таких как Matrix-I (Bruker, Германия) (Burns, Ciurczak, 2007;Efimenko et al, 2015;Efimenko et al, 2016;Abd Manaf, Yap, 2018;Efimenko S.G., Efimenko S.K., 2019). Метод основан на возбуждении колебания молекул при прохождении ИК-излучения через образец (Wheeler, 1959;Vaccari et al, 1990;Burns, Ciur czak, 2007;Abd Manaf, Yap, 2018) и характеристиках процесса возбуждения, которые зависят от особенностей сканируемого материала.…”

Background. A calibration model has been developed for rapid assessment of economic value indicators (protein, oil, and quinolizidine alkaloid contents) in the seeds of narrowleaf lupine accessions from VIR using near-infrared spectroscopy, with the help of which it is possible to decide on the further use of the accessions.Materials and methods. Biochemical quality indicators (protein, oil, and quinolizidine alkaloid content) were studied in the seeds of narrowleaf lupine (Lupinus angustifolius L.) grown in 2019 in the northwest of Russia. Calibration models for measuring protein, oil and alkaloids in lupine seeds (62 accessions) were developed using a MATRIX-I IR analyzer (Bruker Optics, Germany). To construct calibration models, we used the values obtained by chemical analysis methods accepted at VIR. The oil content in lupine seeds was assessed by the defatted dry residue technique in Soxhlet extractors, protein by the Kjeldahl method, and quinolizidine alkaloids by gas chromatography coupled with mass spectrometry. All indicators were recalculated on the dry-weight basis.Results and conclusion. Statistical significance of the developed models was verified according to the results of measuring the content of protein, oil and alkaloids in the seeds of the test batch. The protein and oil content data obtained using a calibration curve did not differ significantly from the results of chemical studies, in contrast to alkaloid indicators. Consequently, the developed calibration model for the MATRIX-I IR analyzer can be used for rapid assessment of protein and oil content in narrowleaf lupine flour samples, thus accelerating the process of obtaining data on the main economic value indicators. The analysis does not require reagents and is safe.

BACKGROUND: The infrared reflection spectroscopy application method for rapid assessment of biochemical parameters in various types of oats is shown. On the basis of the biochemical data obtained in the laboratory of VIR, calibration models of protein, oil and starch content were constructed. AIM: The aim of the study is to develop an express method of near-infrared spectroscopy (NIRS) spectroscopy to determine the main biochemical parameters in oat seeds and to build calibration models for the MATRIX-I IR analyser to quantify the mass fraction of protein, oil and starch in oat seeds based on data obtained by traditional methods. MATERIALS AND METHODS: Biochemical quality indicators (protein, oil, starch) were studied on seeds of filmy oats (Avena sativa L.) grown in 20152016 in the North-Western Region of the Russian Federation. Calibration models for the determination of protein, oil and starch in oat seeds (98 samples, harvest 20142015) were developed for the MATRIX-I IR analyzer by Bruker Optics (Germany). Values obtained by traditional chemical methods of analysis were used to construct calibration models. Oat seed oil was determined by the Soxlet method, protein by the Kjeldahl method, starch by the Evers polarimetric method. All indicators were recalculated for dry weight. RESULTS AND CONCLUSION: The reliability of the developed models was checked by the results of protein, oil and starch determination in the seeds of the test batch according to the indicator of the calibration correctness. The data obtained using the calibration curve on the MATRIX-I device had no significant differences with the results of chemical studies. Therefore, calibration can be used for screening analysis for protein, oil and starch content in oat samples. This method allows you to save valuable material, increase labour productivity due to the speed of obtaining data, does not require reagents and is safe.

The article raises the problem of incomparability of measurement results obtained by different methods of measuring fat content in food products and food raw materials. The problem identified by the author can be solved by developing metrological support for measurements in the food industry. The purpose of the study is to analyze methods for measuring fat content in food products and food raw materials, as well as to revise the state of their metrological support. A brief description, applications, advantages and limitations of extraction-gravimetric, butyrometric, refractometric, chromatographic, ultrasonic, turbidimetric, NMR, and IR spectroscopic methods for measuring fat content are presented. Standardized measurement techniques regulated in national (GOST R), interstate (GOST), and international (ISO, AOAC) standards are analyzed, taking into account the method used, areas of application, and metrological characteristics. An overview of testing equipment and measuring instruments for implementing various methods for determining fat content is given. Particular attention is paid to the consideration of certified express analyzers of food products and food raw materials. A list of certified reference materials for the composition of dairy and grain-milk products, fish and meat products, oilseeds and their processed products, compound feed, egg powder and wheat crackers with a certified value of the mass fraction of fat is provided, their metrological characteristics and certification methods are listed. Based on the results of the study, the main features and problems of ensuring the uniformity of measurements of fat content in food products and food raw materials were formulated, and perspective directions for the development of metrological support were identified.
