"Die Sättigung des sozialen Raumes mit Informationen und Bildern über vermeintliche Bedrohungen durch Fremde, Naturkatastrophen, Epidemien, Sozialabbau, Terrorismus usw. verursacht nicht nur kollektive und individuelle Gefühle der Verunsicherung, Paranoia und Panik, die sich zu einer ‚Kultur der Angst' formieren; sie führt auch zu Maßnahmen von Politik und Wirtschaft, den vermeintlichen Gefahren zu begegnen und permanent Unsicherheit in Sicherheit und Sicherheit in Unsicherheit zu konvertieren." 0
2- and 3-chloropropane-1,2-diol (2- and 3-MCPD) and their fatty acid esters (2- and 3-MCPDEs) together with glycidyl fatty acids esters (GEs) belong to a group of process-induced contaminants. They are formed in high temperature environments and most commonly occur in refined vegetable oils. Since 2021, maximum limits for GEs and 3-MCPDEs have been enforceable in the EU, and the requirement for adequate analytical methods is constantly increasing. The aim of this study was to develop an efficient method to enable a rapid determination of nine 3-MCPDEs and seven GEs in vegetable oils within a single run employing supercritical fluid chromatography coupled to high-resolution tandem mass spectrometry (SFC–HRMS/MS). Contrary to a routine gas chromatography mass spectrometry method aimed at determination of the total MCPD pool, the sample throughput when using SFC–HRMS/MS was greatly increased, as the “dilute-and shoot” approach did not require any hydrolysis and derivatization. Additionally, the pattern of natural MCPDEs was characterized. The performance characteristics of this new method met the criteria required by Commision Regulation 2019/2093 for all target analytes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
