NotesGummies were manually chopped into small pieces, and 1 g of sample was weighed in a 50 mL polypropylene tube. The sample was mixed with 5 mL of water and then vigorously vortexed until all gummy pieces were fully solubilized. The sample was fortified with pesticides and mycotoxins at 100 ng/g. A mix of internal standards was added at 200 ng/g. The spiked sample was further vortexed for 30 sec. 5 mL of acetonitrile acidified with 1% acetic acid was added to the sample, and this was followed by 30 sec vortex agitation. Then, a pouch of European EN 15662 QuEChERS extraction salts (cat.# 25849) was added to the sample. The sample was vortexed for 30 sec and then centrifuged for 5 min. 1.9 mL of supernatant was transferred to a Q-sep QuEChERS dSPE tube containing pre-weighed magnesium sulfate, PSA, and GCB (cat.# 26217). After vortexing and centrifuging, 500 μL of extract was mixed with 500 μL of acidified acetonitrile. 1 μL of final extract was injected into the GC-MS/MS system.
