中文摘要:

      敞开式离子化质谱(ambient mass spectrometry, AMS)是一种能在大气压环境中对样品进行解吸并离子化, 从而获得样品表面信息的新型质谱技术。由于其具有快速、原位、实时分析等优势, 近年来被广泛应用于食品安全快速筛查领域。本文从霉菌毒素类物质的检测, 食品中非法添加物的快速筛查, 食品本身有毒有害物质的鉴定, 食品质量监控, 食品组成成分分析和监测食品中的化学反应六个方面, 综述了以实时直接分析(direct analysis in real time, DART)离子化技术为主的AMS技术在食品安全分析领域的应用。

英文摘要:

      Ambient mass spectrometry(AMS) is a kind of new techniquesthat performs under atmospheric pressure environment, allowing the analysis of sample surfaces. Due to the advantages such as high throughput, real time analysis in situ, no solvent waste, it is widely applied in the rapid screening of food safety. This review presented the applications of ambient mass spectrometry(especially direct analysis in real time) for rapid screening in food safety,including the analysis of mycotoxins, illegal additives, toxic and harmful substances, quality control, food components, and the chemical reactions in food.
