Migration quantification of food contact materials serves as a critical measure for ensuring food safety. This study investigates a migration detection method utilizing gas chromatography-mass spectrometry (GC-MS), with comprehensive validation and uncertainty assessment conducted. Through extraction and analysis of migrating substances from various food contact materials, the method's accuracy and stability in both qualitative and quantitative analysis were validated. The uncertainty evaluation methodology was applied to identify error sources during testing, providing reliable technical support and theoretical foundation for migration quantification. Results demonstrate that GC-MS not only enables efficient detection of migrating substances but also delivers precise quantitative data.
