dc.description.abstractThe determination of pesticide residues in tomatoes is usually performed by GC–MS and LC–MS, which provide high analytical performance but require several steps of sample preparation. Thus, this work employed a simpler and faster technique, the Paper Spray Ionization Mass Spectrometry (PSI-MS), combined with Principal Component Analysis (PCA) to differentiate the tomatoes varieties and for quantification of pesticides residues. It was determined a metabolic profiling by PSI-MS and the samples were grouped according to the variety using PCA. A quantitative method was developed for sensitive and accurate quantitative analysis of the fungicide cyazofamid by PSI(+)-MS using fruit peels of two varieties of tomatoes. The method showed a calibration curve with R2> 0.99, and low limits of detection (LOD) and quantification (LOQ) of 10 ng.mL−¹ and 25 ng.mL−¹, respectively. The intra-day and inter-day recoveries percentage were in a range of 93.87–109.32 % and 99.54–100.81 % for variety Sweet Heaven, respectively. Similar results were obtained for variety BS II0012 with a satisfactory average recovery ranged from 89 % to 108 %, within the standards established by the regulatory agency. The results obtained reinforce the potential of PSI-MS as a rapid and simple analytical tool for determination of pesticide residue in agricultural products.pt_BR
