A Method for the Determination and Confirmation of Priority Pesticide Residues in Baby Food

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.
