Why The Overall Migration Limit (OML) Testing is of Critical Importance in Food Safety Food contact materials, such as plastics, rubber, ceramics, and metals, can release chemical substances into food during contact, posing potential food safety risks. Overall Migration Limit (OML) testing is a crucial indicator for assessing the safety of these materials. Its significance is highlighted in several key areas: Protecting Consumer Health OML testing quantifies the total amount of non-volatile substances that migrate from the material into food. This helps prevent health risks such as chronic poisoning, cancer, and birth defects that could result from excessive levels of harmful substances (e.g., plasticizers, heavy metals, monomer residues). For instance, if phthalate plasticizers from plastics migrate into food, they could disrupt the human endocrine system.

China (GB): The GB 4806 series of standards, such as GB 4806.7-2016 (plastics), specifies an OML of 10 mg/dm². United States (FDA): Through 21 CFR Parts 170-189, the FDA regulates indirect food additives (including migrants), with some scenarios requiring OML to be ≤ 50 mg/kg....

It's widely used for • Measuring migration in various food contact materials and products. • Determining non-volatile residues in pharmaceutical packaging materials. • Similar physicochemical measurements for food, food additives, and pharmaceuticals. Through innovative integrated technology, this system combines the core experimental steps of traditional evaporation residue detection—evaporation,...
Open the catalog to page 3In conclusion, overall migration limit testing is the cornerstone of food contact material safety assessment. By simulating actual use conditions, it quantifies the total amount of chemical substances migrating from materials into food, ensuring product compliance with regulations and safeguarding consumer health. Detection requires strict adherence to standard methods (e.g., GB 31604.8, ISO 10993-17) and relies on high-precision instruments (e.g., migration cells, overall migration limit and non-volatile residue analyzers) to achieve reliable results. For businesses, establishing a comprehensive...
