Abstract

The present invention provides a high performance liquid chromatography-tandem mass spectrometry method for simultaneous determination of specific migration of 18 phenols or phenol derivatives in five plastic food simulants. The method is as below: soaking a sample to be measured in food simulants, cooling to room temperature, mixing well, filtering a water-based soaking liquid by a PTFE syringe needle filter; t extracting vegetable food simulant with acetonitrile, and filtering the supernatant by a PTFE needle filter, and introducing sample; eluting and separating by a C8 column; and running under negative multiple reaction monitoring mode by using a mass spectrometry with electro-spray ionization source. The method has good chromatographic separation, linear relationship, high recovery and accuracy, meets limited requirements of 18 phenols or phenol derivatives in EU regulations NO 10/2011, and provides a quick and convenient method for the detection of the actual sample.

Description

technical field [0001] The invention belongs to the field of compound detection, and relates to a detection method for the specific migration of harmful 18 kinds of phenols and their derivatives in food contact materials, in particular to a high performance liquid chromatography tandem mass spectrometry (HPLC-MS / MS) method for the determination of plastics Detection method for the specific migration of 18 phenols and their derivatives in food packaging materials and containers. technical background [0002] A variety of phenols or phenolic derivatives are used as raw materials or functional additives such as antioxidants, ultraviolet absorbers, bactericidal and antifungal agents, and molecular weight regulators, and are added to plastics to increase the performance and appearance of plastic products. However, some added phenols or phenolic derivatives are also highly toxic. The functional additives of phenols or phenolic derivatives added to some plastic food contact materia...
