Abstract

The invention provides a method for detecting bisphenol A derivatives in a drink with LC-MS-MS (liquid chromatography-mass spectrometry-mass spectrometry). The method comprises the following steps of: (1) determining LC-MS-MS conditions; (2) detecting standard liquid of the bisphenol A derivatives of a target detection object according to the LC-MS-MS conditions and drawing a standard curve of the corresponding bisphenol A derivatives according to a detection result; (3) carrying out sample pretreatments including refrigerated centrifugation, dilution and filtering on the drink, detecting according to the LC-MS-MS conditions, comparing the detection result with the standard curve and calculating the contents of the corresponding bisphenol A derivatives in the sample. The detection method is high in sensitivity and accuracy, short in detection time, good in recovery test effect and suitable for standardization. By utilizing the method, nine or more bisphenol A derivatives can be detected simultaneously.

Description

technical field [0001] The invention relates to a method for detecting bisphenol A derivatives in beverages, in particular to a method for quantitatively detecting bisphenol A derivatives in beverages by LC-MS-MS. Background technique [0002] Bisphenol A (Bisphenol A, BPA) is one of the most widely used industrial compounds in the world, mainly used in the production of polycarbonate, epoxy resin, polysulfone resin, polyphenylene ether resin, unsaturated polyester resin, etc. Polymer Materials. Discussions about bisphenol A have been in European and American countries for a long time, until March 22, 2010, the Danish government confirmed the research results published by the Danish University of Science and Technology-National Food Research Institute (DTUFood)-bisphenol A will affect the nervous system and activities ability, all countries have a unified understanding of the impact of bisphenol A. The European Union believes that bisphenol A can be precipitated into food ...
