Abstract:

This article summarized 41 types of primary aromatic amines （PAAs） related to food contact materials in domestic and foreign regulations， standards， technical guidelines， and references and analyzed the source and migration risk of PAAs in food contact materials. Moreover， the differences in technical regulations of PAAs in China， the European Union， and South Korea before 2021 were compared. Based on these investigations， PAAs in food contact materials were mainly derived from azo colorants， aromatic isocyanates， and other additives， and they were detected from polyamide tableware， colored plastic products， and composite products， especially in polyamide tableware and kitchenware. The specific migration of all PAAs in plastic food contact materials and products has been restricted by the European Union. As a member of the European Union， Germany restricts the migration of PAAs from six high?risk materials such as plastic colorants and rubber. South Korea restricts the specific migration of 4，4’?diaminodiphenylmethane in epoxy resin and aniline， 4，4’?diaminodiphenylmethane and 2，4?diaminotoluene in polyamide plastics. China restricts the specific migration of toluene diamine in composite food packaging bags， m?phenylenediamine， 4，4'?diaminodiphenylsulfone in plastic re?sins， and the amount of PAAs used in colorants was also limited. The migration risk of PAAs in plastic food contact materials has received widespread attention at present in China. It is recommended that manufacturers pay much attention to the differences in domestic and foreign laws and regulations and strictly control the migration risk of PAAs in azo colorants， aromatic isocyanates， and other additives.
