A Method for the Determination and Confirmation of Priority Pesticide Residues in Baby Food
Seventeen priority pesticides were extracted from baby food, using dispersive solid phase extraction which helped to remove interfering matrix components.
Seventeen priority pesticides were extracted using dispersive solid phase extraction which helped to remove interfering matrix components. Ultrahigh-pressue LC (UHPLC) was used to separate the pesticides by applying a simple acidified gradient of water to methanol. A rapid determination and confirmation of the pesticide residues was achieved with fast MS acquisition rates. The results obtained were able to exceed current worldwide pesitcide legislated limits in fruit and meat based baby food extracts.
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.
