This review is the first to summarize a decade of studies testing the use of easy ambient sonic-spray ionization mass spectrometry (EASI-MS) and its several sister techniques, Venturi (V-EASI), thermal imprinting (TI-EASI) and Spartan (S-EASI) mass spectrometry in food quality control and authentication. Since minimal or no sample preparation is required, such ambient desorption/ionization techniques have been shown to provide direct, fast and selective fingerprinting characterization at the molecular level based on the pools of the most typical components. They have also been found to be applicable on intact, undisturbed samples or on simple solvent extracts. Fundamentals of EASI-MS and its sister techniques, including mechanisms, devices, parameters and strategies, as well as the many applications reported for food analysis, are summarized and discussed.
本综述首次总结了十年来对简易常压声波喷雾电离质谱（EASI-MS）及其几种衍生技术，即文丘里（V-EASI）、热印记（TI-EASI）和斯巴达（S-EASI）质谱在食品质量控制和认证方面的应用研究。由于这些常压解吸/电离技术所需的样品制备极少或无需样品制备，已证明它们能够基于最典型成分的集合在分子水平上提供直接、快速且具有选择性的指纹图谱表征。还发现它们适用于完整、未受干扰的样品或简单的溶剂提取物。本文总结并讨论了EASI-MS及其衍生技术的基本原理，包括其机制、装置、参数和策略，以及报道的在食品分析中的众多应用。
