Owing to the different toxicity and biodegradation rate of enantiomers, their analysis is a urgent need in a fundamental staple such as milk, especially because it is a food highly consumed by children. The following work describes a high throughput method for the simultaneous analysis of eleven pesticides, five out of which are racemic mixtures of optical isomers and one is an equimolar mixture of geometric isomers. The extraction procedure allows one to process 18 milk samples per hour thanks to its quickness and ease, albeit the matrix complexity. Two approaches, typically applied for protein precipitation separately (lowering of the medium dielectric constant with cold acetonitrile and salting out effect with ammonium sulphate), were combined to maximize protein removal. The salting out phenomenon also promoted the water/acetonitrile separation and favoured the analyte transfer into the organic phase. After evaporation, the reconstituted extracts were analysed by enantioselective high-performance liquid chromatography combined with dual-polarity tandem mass spectrometry, allowing the complete separation of seventeen chromatographic peaks in a 15-min run.
