GB 31604.44-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Migration of Ethylene Glycol and Diethylene Glycol (English Version)
1 Scope
This standard specifies thedetermination method of gas chromatography for the migration of ethylene glycol and diethylene glycol in food contact materials and articles.
This standard is applicable to the determination of migration of ethylene glycol and diethylene glycol in food contact materials and articles.
2 Principle
Separate the ethylene glycol and diethylene glycol in food container and packaging material simulants by capillary gas chromatographic column and detect with hydrogen flame ionization detector. For the water-based, acidic or alcoholic food simulant, directly inject the sample; for the oil-based food simulant, inject the sample after water extraction for analysis; carry out the quantitative determination by internal standard method with 1,4-butanediol as the internal standard substance.
