SCREENING AND QUANTITATIVE ANALYSIS OF NON INTENTIONALLY ADDED SUBSTANCES ELUTED FROM POLYETHYLENE TEREPHTHALATE BOTTLE BY HIGH-RESOLUTION MASS SPECTROMETRY

摘要

Food packaging materials can contain a wide range of known and unknown substances [1]. Chemicals such as impurities of ingredient, by-products, and degradation products are also plausible. These chemicals are referred to as non-intentionally added substances (NIAS). In this study, NIAS from polyethylene terephthalate (PET) bottles were examined by liquid chromatography high-resolution mass spectrometry (LC/HRMS).
