Trends in the development of analytical methods for determination of the quality and authenticity of foodstuffs

The review presents several results of investigations carried out at the Federal Research Centre for Nutrition, Biotechnology and Food Safety on the development and application of modern chemical-analytical methods for determining the quality indicators, nutritional and biological value of foodstuffs. Particular attention is paid to methodological approaches to the determination of biologically active substances of dietary supplements of plant origin, to the definition of criteria for authenticity and methods to disclose falsification of food and dietary supplements. The practical application of modern analytical techniques (capillary GLC, capillary electrophoresis, HPLC with a mass spectrometric detection, UV/VIS diode-array detection, etc.), combining high efficiency and selective separation and detection for identification and qualitative and quantitative determination of components in complex matrix of foodstuffs and dietary supplements is shown.
