Summary
A new migration test accurately detects trace epichlorohydrin in food can coatings. This method confirmed no epichlorohydrin migrated from tested epoxy resin-coated cans, ensuring food safety.
Area of Science:
- Analytical Chemistry
- Food Science
Context:
- Internal can coatings, particularly epoxy resins, are used for food and beverage packaging.
- Epichlorohydrin is a potential migrant from these coatings that requires sensitive detection.
Purpose:
- To develop and validate an improved migration test for trace epichlorohydrin in internal can coatings.
- To assess epichlorohydrin migration from various food and beverage can samples.
Summary:
- An optimized migration test using n-pentane as a food simulant was established for can bodies and lids.
- Gas chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC/MS) were employed for sensitive epichlorohydrin quantification.
- The method demonstrated high precision and recovery rates (99.9-104.5%), with limits of quantitation at 0.05 µg/mL (GC-FID) and 0.02 µg/mL (GC/MS).
Impact:
- The study established a reliable analytical method for monitoring epichlorohydrin migration.
- No epichlorohydrin migration was detected in the tested epoxy resin-coated food and beverage cans.
- This research contributes to ensuring the safety of food packaging materials.
