Abstract

The invention discloses a determination method of a migration amount of a phthalate ester plasticizer in a food contact material. The determination method comprises the following steps of adding a food contact material sample after being cut into pieces in a waterborne food analogue test solution, soaking a mixture with a thermostatic waterbath, adding a supermolecule solvent in obtained migrationliquid, performing shaking extraction and centrifugation, taking supernatant liquid, diluting the supernatant liquid with methanol, and adopting ultra-high performance liquid chromatography-tandem mass spectrometry for determination, wherein the supermolecule solvent is a mixed solution of n-octanol, tetrahydrofuran and water. The determination method of the migration amount of the phthalate ester plasticizer in the food contact material is accurate and reliable, is simple and convenient to operate and is suitable for detection of the migration amount of the phthalate ester plasticizer in thefood contact material.

Description

Technical field [0001] The invention relates to a detection method of chemical substances, in particular to a supramolecular solvent dispersion liquid-liquid microextraction-ultra-high performance liquid chromatography-tandem mass spectrometry method for determining the migration amount of phthalate ester plasticizers in food contact materials. Methods. Background technique [0002] Food contact materials refer to materials that come into contact with food during normal use of products, including food containers, packaging materials, food packaging equipment and other materials that may come into contact with food. However, food usually has different forms, so the requirements for food packaging are also different. At the same time, food contact materials and products may release a certain amount of toxic chemical components during the process of contact with food, and these chemical components will migrate It enters food and is ingested by the human body, endangering human...
