Pesticide Residue in Fruits and Vegetables

Here are the top five articles published on LCGC International this week.

Food 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.

At HTC-18 in Leuven, Executive Editor of LCGC International, Alasdair Matheson, spoke to Chiara Cordero from the University of Turin about the evolving role of AI and its effect on GCxGC in foodomics.

Tarun Anumol of Agilent Technologies discusses the biggest challenges laboratories are experiencing in PFAS testing along with some potential solutions.

Scientists from Chemisches und Veterinäruntersuchungsamt Münsterland-Emscher-Lippe recently tested a new method for determining PFAS in food and food contact materials.

Jan H. Christensen is a Professor in Environmental Analytical Chemistry at the University of Copenhagen. At HTC-18, we interviewed him about his presentation about non-targeted screening of environmental samples.
