Abstract
[Objective] To explore the determination methods and migration patterns of 22 organophosphate flame retardants (OPFRs ) in degradable food contact materials. [Methods] Samples were soaked in four kinds of food simulants. Ten percent ethanol and 3% acetic acid simulants were extracted with acetonitrile and salted out with NaCl. Olive oil was extracted with methanol/acetonitrile (v/v, 2/3), and 50% ethanol simulants were filtered and directly measured. OPFR extracts were separated by a C18 column and determined by positive electrospray ionization (ESI+) in multiple reaction monitoring mode, with quantification by matrix external standard method. The migration pattern of triphenyl phosphate (TPhP ) in simulants was analyzed and applied to determine migration of OPFRs in biodegradable food packaging bags and disposable gloves. [Results] The recoveries of 22 OPFRs ranged from 76. 7% to 119. 9%, with relative standard deviations of 0.23% to 11. 30%. Limits of detection ranged from 0.06 to 1. 14 μg/L, and limits of quantification ranged from 0.20 to 3. 75 μg/L. Migration of TPhP from degradable food contact materials into 50% ethanol and olive oil increased with soaking time and temperature. Among 26 samples, the detection rate of OPFR migration was 76. 9%, with only TPhP detected, migrating exclusively into 50% ethanol and olive oil. [Conclusion] Prolonged contact of degradable food packaging bags and disposable gloves with fatty foods or dairy products poses a safety risk due to OPFR migration into food.
