| Abstract: |
| A high performance liquid chromatographic（HPLC） method was developed for the determination of migration amounts of 19 UV absorbers in food contact materials.Influences of different food simulants and immersion time on the migration of UV absorbers were investigated.The results showed that the low migration of UV absorbers was found in water,3% acetic acid and low concentration ethanol,while the high migration was found in 95% ethanol and isooctane,which can be explained by their molecular structure.The migration of UV absorbers in food contact material was similar in immersion at 80 ℃ for 6 h and 40 ℃ for 10 d.The calibration curves were linear in the range of 0.5-20 mg/L for 19 UV absorbers,with correlation coefficients more than 0.999 5.The recoveries at three spiked levels ranged from 83.8% to 98.0% in 95% ethanol and isooctane.With high sensitivity,recovery and selectivity,the method could fully meet the requirements for practical work. |
