The method for seafood spoilage detection is far from satisfactory for ensuring food safety and security. Here, we develop a simple and cost-effective method using the filter papers loaded with a dihydroquinoxaline derivative (H + DQ2) to monitor salmon spoilage. The correlation between the content of solid biogenic amines and the photoluminescence intensity (PL) of H + DQ2 induced by amine vapours showed that the PL intensities of H + DQ2 increased with the increase of spoilage, which indicates that it is feasible to evaluate the spoilage degree of salmon based on the PL intensity of H + DQ2-loaded filter papers by semi-quantitation. The optimum detection condition is 75, 50 and 50 g of salmon, 75, 25 and 10 µM H + DQ2 at 0, 4 and 25 °C, respectively. This study provides a quick and simple way for testing amine vapour from fish and provides baseline information for developing an easy-to-use on-site method to evaluate seafood quality for customers.
用于海鲜变质检测的方法远不能确保食品安全。在这里，我们开发了一种简单且具有成本效益的方法，使用负载有二氢喹喔啉衍生物（H+DQ2）的滤纸来监测三文鱼的变质。固体生物胺含量与胺蒸气诱导的 H+DQ2 光致发光强度（PL）之间的相关性表明，H+DQ2 的 PL 强度随着变质的增加而增加，这表明基于 H+DQ2 负载滤纸的 PL 强度通过半定量评估三文鱼的变质程度是可行的。最佳检测条件分别为 75、50 和 50g 三文鱼，75、25 和 10µM H+DQ2，温度分别为 0、4 和 25°C。本研究为测试鱼肉中的胺蒸气提供了一种快速简单的方法，并为开发一种易于客户使用的现场评估海鲜质量的方法提供了基础信息。
