title: Sample preparation methods in the analysis of pesticide residues in baby food with subsequent chromatographic determination.
abstract: Pesticides are widely utilized at various stages of cultivation and during postharvest storage to protect plants against a range of pests and/or to provide quality preservation. Reliable confirmatory methods are required to monitor pesticide residues in baby foods and to ensure the safety of baby food supply. This review covers methods in which pesticide residues have been determined in baby food by the use of a wide range of chromatographic techniques after various sample preparation steps. The main attention is paid to the evaluation and improvement of sample extraction and clean-up methods (liquid extraction, solid-phase extraction (SPE), dispersive SPE (DSPE), microextraction procedures, matrix solid-phase dispersion (MSPD) and supercritical fluid extraction (SFE)) considering low concentration levels of pesticide residues in baby food resulting from stringent European Union (EU) legislation. Instrumental aspects together with the matrix effects significantly contributing to the most important parameters considered in pesticide residues analysis of baby food--limits of detection (LODs) and limits of quantification (LOQs) were included within the scope of this overview. Paper involves also monitoring studies.
