Abstract

Selenium (Se) is a vital trace element for mammals, but excessive intake can lead to selenium poisoning. To manage Se intake properly, this study developed a novel method using ultra-high performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). This technique allows the simultaneous detection of three selenoamino acids in supplements. The three selenoamino acids were fully separated within 3 min. The method demonstrated excellent linearity (R² ≥ 0.9993), high sensitivity (detection limits were 2.49–2.92 fmol), and good precision (intraday and interday precision ranged from 2.87 to 13.54%). This study applied this method to analyze the content of selenoamino acids in organic selenium supplements from various sources and to dynamically monitor their absorption and excretion in the body after consumption. The novel approach offers a new strategy for the quality control of selenium-containing supplements and for studying selenium absorption and metabolism.

期刊介绍： The journal European Food Research and Technology publishes state-of-the-art research papers and review articles on fundamental and applied food research. The journal''s mission is the fast publication of high quality papers on front-line research, newest techniques and on developing trends in the following sections: -chemistry and biochemistry- technology and molecular biotechnology- nutritional chemistry and toxicology- analytical and sensory methodologies- food physics. Out of the scope of the journal are: - contributions which are not of international interest or do not have a substantial impact on food sciences, - submissions which comprise merely data collections, based on the use of routine analytical or bacteriological methods, - contributions reporting biological or functional effects without profound chemical and/or physical structure characterization of the compound(s) under research.
