桶装方便面包装材料发射谱图的研究

Research on the Emission Spectrogram of the Drum Instant Noodles' Packing Materials

桶装方便面是人们旅游外出的便捷食品,但目前关于其包装材料中存在荧光增白物质的新闻也是屡屡出现。本文应用天津港东F-380型荧光分光光度计对四种桶装方便面包装的4个不同部位进行发射谱图的测试,通过对比试验证明这些方便面桶装包材中确实含有荧光物质,其主要存在于内侧聚乙烯膜和彩色包材之间的白纸层中。

The drum instant noodles are convenient food for people when traveling ,but currently , news about the fluorescent whitening substances in the packing materials have repeatedly appeared .This article has adopted Tianjin Gangdong F -380 fluorescence spectrophotometer to conduct the emission spectrogram test on 4 different parts of the four kinds of drum instant noodles ,and it has been proved through contrast test that the packing materials of these drum instant noodles do contain the fluorescent substance ,which mainly exists on the white paper layer between the inner side of the polyethylene film and the colorized packing materials .
