GB 31604.12-2016 National Food Safety Standard - Food Contact Materials and Articles - Determination of 1,3-butadiene and Determination of Migration (English Version)
1 Scope
This standard specifies determination method of 1, 3-butadiene in food contact materials and articles and its migration in such materials and articles.
This standard is applicable to the determination of 1, 3-butadiene in food contact materials and articles and its migration in such materials and articles.
Determination of 1, 3-butadiene
2 Principle
Dissolve or disperse the food contact materials and articles with N, N-dimethyl formamide in a headspace bottle, heat to make the to-be-tested constituent reach gas-liquid equilibrium and then pipet headspace air quantitatively to determine gas chromatography. Carry out the qualitative determination by retention time and quantitative determination by internal standard method with n-pentane as internal standard substance.
3 Reagents and Materials
Class-I water (defined in GB/T 6682) is adopted for the purposes of this method. As for the containers and transferring tools in the test, those made of plastic material shall not be used.
