GB 31604.17-2016 National Food Safety Standard - Food Contact Materials and Articles - Determination of the Content and Migration of Acrylonitrile (English Version)
1 Scope
This standard specifies the determination method of acrylonitrile and migration in food contact materials and articles.
This standard is applicable to the determination of acrylonitrile and migration in food contact materials and articles.
Determination of Acrylonitrile
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 carry out gas chromatograph determination. Qualify as per retention time and quantify as per internal standard method with propionitrile as internal standard substance.
3 Reagents and Materials
Class-I water (defined in GB/T 6682) is adopted for the purpose of this method. The plastic material shall not be used for the container and transferring tool in the test.
3.1 Reagent
N, N-dimethyl formamide (DMF): analytical reagent, free of interference peak within the range of retention time of acrylonitrile and propionitrile.
3.2 Standard products
3.2.1 Acrylonitrile (C3H3N, CAS No.: 107-13-1): 1000μg/mL, or reference material approved and awarded with reference material certificate by the State.
3.2.2 Propionitrile (C2H5CN, CAS No.: 107-12-0): 1000μg/mL, or reference material approved and awarded with reference material certificate by the State.
