基于比色传感器可视化检测虾的新鲜度

Visual Detection of Shrimp Freshness via Colorimetric Sensors

摘要

生物胺是虾类腐败的代谢副产物， 监测生物胺水平对评估食品质量至关重要. 目前， 大多数生物胺检测方法存在程序耗时、 操作复杂和结果延迟等局限性. 近年来， 比色分析技术因其分析时间短、 操作简单、 适合现场检测等优点而备受关注. 本文通过在滤纸和电纺纳米纤维膜（ENFs）上分别添加天然活性成分姜黄素（CUR）及其衍生物硼络合物BFCUR， 开发了一系列生物胺类比色传感器平台. 通过分析这些传感器与生物胺接触时的颜色反应差异， 筛选出检测性能优越的比色传感器， 并进一步应用于虾类腐败过程的视觉监测和指示.

Abstract

Monitoring biogenic amines， which are metabolic byproducts of shrimp spoilage， is crucial for assessing food quality. Currently， most detection methods for biogenic amines suffer from limitations such as time-consuming procedures， complex operations， and delayed results. Colorimetric analysis techniques have gained attention in recent years due to their advantages of short analysis time， simple operation， and suitability for on-site testing. This study successfully developed a series of colorimetric sensor platforms for biogenic amines by loading the natural active ingredient curcumin（CUR） and its derivative of Boron complex BFCUR onto filter paper and electrospun nanofibre films（ENFs）， respectively. By analyzing the color response differences of these sensors upon contact with biogenic amines， the colorimetric sensors with superior detection performance were selected and further applied to the visual monitoring and indication of shrimp spoilage processes.
