GB 31604.15-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Migration of 2,4,6-triamino-1,3,5-triazine(melamine) (English Version)
1 Scope
This standard specifies the determination method of migration of melamine in food contact materials and articles (melamine formaldehyde resin and finished products).
This standard is applicable to the high performance liquid chromatography determination method for migration of melamine in food contact materials and articles (melamine formaldehyde resin and finished products).
2 Principle
Contact the food contact materials and articles (melamine formaldehyde resin and finished products) with the food simulants and carry out the migration test under specific soaking conditions. Test the solution obtained after soak solution treatment with high performance liquid chromatography, and convert the result to special migration of melamine. Select corresponding food simulant and migration test conditions (duration and temperature) respecting the food category in accordance with GB 31604.1. If the food simulant is composed of water, acetic acid of 4% (volume fraction) and ethyl alcohol of 10%, 20% or 50%~95% (volume fraction), the soak solution shall be taken as directly injected as test solution; if the food simulant is vegetable oil, the test solution obtained after extraction treatment to the soak solution shall be directly injected. Then determine the melamine content in the test solution with high performance liquid chromatography, determine the soak solution volume and specimen contact area in accordance with GB 5009.156 and convert them to special migration (settling out amount of the migrating substance) of melamine according to the formula.
