GB 31604.30-2016 National Food Safety Standard - Food Contact Materials and Articles - Determination of the Content and Migration of Phthalate Esters (English Version)
1 Scope
This Standard specifies method of determination of the content and migration of phthalate esters in materials in contact with foodstuffs and their products.
This Standard is applicable to determination of the content of phthalate esters in food plastic packaging materials and their products as well as the migration of phthalate esters in materials in contact with foodstuffs and their products.
Determination of Content of Phthalate Esters
2 Principle
Mill food plastic packaging material and its product, perform ultrasonic treatment with normal hexane, filter the extract, and conduct the determination by gas chromatography-mass spectrometry method (GC/MS). Adopt selected ion monitor mode (SIM), determine the chemical composition according to retention time and fragment abundance ratio, and determine the amount by external standard method.
3 Reagents and Materials
Unless otherwise specified, all reagents used in this method are chromatographically pure (or analytically pure after double distillation). The water used shall be the water that is redistilled with full-glass apparatus and stored in a glass vessel.
3.1 Reagents
3.1.1 Normal hexane (C6H14).
3.1.2 Acetone (CH3COCH3).
3.2 Phthalate esters standard products
Dimethyl phthalate (DMP), diethyl phthalate (DEP), diethyl phthalate (DAP), diisobutyl phthalate (DIBP), dibutyl phthalate (DBP), bis (2-methoxyethyl) phthalate (DMEP), bis (4-methyl-2-pentyl) phthalate (BMPP), bis(2-ethoxyethyl) phthalate (DEEP), diamyl phthalate (DPP), dihexyl phthalate (DHXP), benzyl butyl phthalate (BBP), Bis (2-n-butoxyethyl) phthalate (DBEP), dicyclohexyl phthalate (DCHP), Bis (2-ethylhexyl) phthalate (DEHP), diphenyl phthalate (DPhP), Di-n-octyl phthalate (DNOP), diisononyl phthalate (DINP), dinonyl phthalate (DNP), with purity > 95.0%.
