This work deals with the application of the QuEChERS method for extraction of synthetic food dyes (SFD) from confectionery samples: tartrazine (E102), quinoline yellow (E104), cochineal red A (E124), allura red (E129), patent blue V (E131), and brilliant blue (E133). Extraction conditions, like extraction solvent and its amount, sample amount, the pH adjustment and addition of salt, were optimised. The 5 mL of sample, 2 mL of propan-1-ol as extraction solvent with addition of 0.6 g NaCl, 2.4 g MgSO4, and 0.75 mL 35% HCl were experimentally found to be optimal. Analyses of extracts were performed by liquid chromatography with detection of SFD in the visible region. Recoveries of SFD were in the range of 79.3-100.0% with intra-day precision b...
