Pressurized Liquid Extraction of Amines in Meat
Researchers from the University of Barcelona (Barcelona, Spain) analyzed heterocyclic amines in meat samples using pressurized liquid extraction followed by liquid chromatography with tandem mass spectrometry detection (LC?MS-MS).
Researchers from the University of Barcelona (Barcelona, Spain) analyzed heterocyclic amines in meat samples using pressurized liquid extraction followed by liquid chromatography with tandem mass spectrometry detection (LC?MS-MS). Factors such as temperature and extraction time were varied to obtain the best analyte recovery. The optimum extraction method used a methylene chloride?acetone solution at 80 C for 10 min. The method reportedly reduces total extraction time by fourfold compared with the usual solid-phase extraction method.
Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
