Abstract

|
|
|
The method for the determination of ethylenediamine (EDA) and hexamethylenediamine (HMDA) in food simulants was developed, and migration amounts of these compounds was monitored for 124 polyamide (PA) utensils. The diurethane derivatives of EDA and HMDA, which produced by reaction with ethyl chloroformate, were analyzed by using gas chromatograph (GC)/flame ionization detector (FID) and GC/mass spectrometer (MS). The developed method was validated with 0.3 μg/mL of limit of detection (LOD) for EDA and 0.1 μg/mL of LOD for HMDA, > 0.999 of linearity(r2) and > 88% of recovery. The EDA was detected 1.31 and 2.06 μg/mL for 2 samples in water. The HMDA was detected 0.29 - 0.93 μg/mL for 3 samples in 20% ethanol and 0.26 - 0.44 μg/mL for 10 samples in n-heptane. These migration levels were below the specific migration limits (SML) of 12 μg/mL and 2.4 μg/mL for EDA and HMDA established in EU.
