重金属的危害及其在食品包装材料上的快速检测方法

The Harm and Rapid Detection Methods of Heavy Metals in Food Packaging Materials

摘要: 对于食品来说，包装不仅起着宣传和美化的作用，更对食品起着保护作用。但是食品包装材料中存在一些重金属对食品食用安全有一定隐患。用激光诱导击穿光谱结合移动窗口偏最小二乘法、原子荧光光度法、X射线荧光光谱等方法能安全快速的对重金属离子进行检测，其中，荧光光度法、X射线荧光光谱测量成为了食品包装材料重金属离子快速检测研究的一个重要方面。本工作对各种材料中重金属快速检测的方法进行归纳、总结，并对最新的技术方法进行了分析，这对人们了解食品包装安全及检测方法方面具有重要意义。

Abstract: For food, food packaging plays a very important role, which not only plays a role in publicity and beautification, but also plays a protective role in food. However, there are some heavy metals in food packaging materials, which have some hidden dangers to food safety. By laser induced breakdown spectroscopy combined with moving window partial least-squares method, atomic fluorescence spectrophotometry, X-ray fluorescence spectrum method, these heavy metals of packaging material can be rapidly detected. The rapid detection methods for the various heavy metals in materials were summarized, and the latest detection method was analyzed, which are of great significance to the understanding of the food packaging safety and detection.
