Investigation on Determination of 19 UV Absorbers in Food Contact Materials and Their Migration Regularity[J]. 2015,34(1):20-27.
建立了食品接触材料中19种紫外光吸收剂迁移量测定的高效液相色谱法。研究了不同食品模拟物及浸泡时间对紫外光吸收剂迁移量的影响。实验结果表明,紫外光吸收剂在水、3%乙酸、低浓度的乙醇中迁移量低,在95%乙醇和异辛烷模拟物中迁移量高,迁移规律性与紫外光吸收剂的分子结构密切相关。食品接触材料中紫外光吸收剂在80 ℃浸泡6 h的迁移量与40 ℃浸泡10 d相当。所建立液相色谱法的定量下限为0.1~0.5 mg/kg,在95%乙醇和异辛烷模拟物中,3个加标水平下的回收率为83.8%~98.0%。方法的灵敏度与回收率高,选择性好,能满足实际工作的要求。
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.
