Testing The Overall Migration in Food Contact Materials

The integrity of food contact materials (FCMs) is paramount in safeguarding consumer health. Regulatory bodies and industry stakeholders recognize the critical role these materials play in maintaining food quality and safety. A fundamental aspect of FCM evaluation is the assessment of overall migration, a process designed to quantify the potential transfer of non-volatile substances from packaging and containers into food.

Overall migration refers to the determination of the total quantity of non-volatile constituents that may migrate from an FCM into food simulants under defined conditions. The evaluation of overall migration is integral to ensuring compliance with regulatory standards, which mandate that FCMs do not release substances into food in quantities that could pose a risk to human health. Regulatory agencies establish Overall Migration Limits (OMLs), typically expressed in milligrams of migrants per square decimeter (mg/dm²), to define acceptable levels of substance transfer.

To accurately simulate food contact scenarios, standardized food simulants are employed. These simulants mimic the properties of various food types, including aqueous, acidic, fatty, and alcoholic matrices. Testing protocols involve exposing FCM samples to the appropriate simulant under precisely controlled conditions of temperature and time, reflecting realistic or worst-case usage scenarios. Subsequent analysis of the simulant involves the quantification of non-volatile migrants, often achieved through evaporative techniques and gravimetric determination.
