Migration of chemical substances from packaging materials to food.

Abstract

At present, active food packaging is favored by manufacturers and consumers from all over the world for various special functions. However, the potential migration of chemical substances from the packaging into the food during contact is a significant concern. Therefore, a detailed discussion of this topic is warranted. This paper begins with a thorough analysis of the migration mechanisms, mathematical models, and critical parameters involved in the migration of chemical substances from food packaging. On this basis, it summarizes relevant detection techniques, the selection of food simulants, and risk assessment, which are crucial for the accuracy of migration test results. In addition, specific attention was focused on the migration of antimicrobial agents in food packaging. Finally, non-destructive testing methods, international legislation, and current opportunities and challenges were discussed. The research provides important guidance and inspiration for investigating the migration of chemical substances from food packaging to food.
