Resolving Saturated Polyolefin Hydrocarbon Oligomer Interference in Mineral Oil Migration Dossiers
Polyolefin oligomer co-elution requires epoxidation clean-up and GCxGC deconvolution to prevent false mineral oil failures in migration dossiers.
JRC Guidelines
Meaning
Technical documents published by the Joint Research Centre of the European Commission provide the methodology for assessing the safety and compliance of materials intended for food contact. JRC guidelines establish the testing protocols for measuring the migration of chemical substances from plastics into food simulants. They cover the preparation of samples and the selection of appropriate simulants like olive oil or ethanol.
Analytical methods required for detection are also specified.
Migration Testing
Standardized exposure conditions defined in the text simulate real-world usage such as microwave heating or long-term storage. Under the JRC guidelines, laboratories must account for the ratio of the surface area of the package to the volume of the food. This calculation ensures that the specific migration limits for additives like phthalates or antioxidants are not exceeded.
Analytical Method
Specificity in detection is achieved through gas chromatography or mass spectrometry as recommended by the authority.
Quality Assurance
Documenting the provenance of every resin batch and additive becomes a legal requirement for converters. Adherence to the JRC guidelines protects manufacturers from product recalls and legal liability stemming from chemical contamination. These protocols are updated regularly to include new findings on endocrine disruptors and non-intentionally added substances.
