Abstract
To established an analytical method for determination of the migration amount of 32 additives in food contact materials by high performance liquid chromatography, and investigate the migration levels of 32 additives in plastic food contact materials sold in market. Samples selected from 103 batches of plastic food contact materials of different textures were soaked by isooctane, 50% ethanol, 20% ethanol, 10% ethanol, 3% acetic acid to obtain simulants. They were analyzed by HPLC, and quantitated by external standard method. DBP, DEHP, benzophenone, UV-1577, antioxidant BHT, 697, 2246, BHEB and fluorescent brightener 184 were detected and qualified. The migration amount of DBP or DEHP in 11 batches of PVC, benzophenone in 1 batch of PP, and UV-1577 in 1 batch of PC materials exceeded the standard limit. The above additives had the highest detection rate in isooctane and had a lower detection rate in 50% ethanol and were not detected in the other three simulants. Plastic food contact materials should not be used directly for contact with oil and high concentrations of alcoholic food. There was a potential risk of benzophenone in PP materials, UV-1577 in PC materials, DBP and DEHP in PVC materials. Regulation and monitoring on these additives in plastic food contact materials should be strengthened.
