Abstract:
In this study, ethylene oxide (EO), a fumigant for agricultural products, and its & nbsp;metabolite (2-chloroethanol, 2-CE), were extracted by QuEChERS method, and then & nbsp;quantified by GC-MS/MS system. Samples were extracted with acetonitrile, and cleaned up & nbsp;with a mixture of dispersive solid phase extraction (d-SPE), including MgSO4, PSA, C18 & nbsp;and GCB, within less than 20 min. The method has been validated on spices, oils, noodle, & nbsp;and food packaging. The results show that this method was high accuracy and precision at & nbsp;spike concentrations, with recovery ranged from 80 to 120%, and RSD lower than 20%. The & nbsp;limit of quantification was 0.01 mg/kg for both compounds, meeting the European (EU) & nbsp;maximum residue limit (MRL) at 0.01 mg/kg. This method has been applied to control the & nbsp;production of instant noodles, with 125 samples of ingredients (seasoning, dried vegetables, & nbsp;oil, flour, food packaging), instant noodles and other food. Among them, 13 ingredients & nbsp;detected 2-CE, and 1 spice detected both compounds, accounting for 11.2%. All 14 samples & nbsp;exceeded the EU MRL. & nbsp;
