拉曼光谱技术在农产品药物残留检测中的应用

近年来,农产品药物残留超标引发了一系列食品安全问题,为了保障国家食品安全、保护消费者健康,需要对农产品中的药物残留进行定性定量检测。表面增强拉曼散射技术 (Surface-enhanced Raman scattering , SERS) 是一种极具吸引力的工具,可用于高效检测农药残留。本文介绍了表面增强拉曼光谱检测技术的概况,简介了拉曼增强基底,分析了表面增强拉曼光谱技术在药物标准溶液、农产品(肉类、水产品、果蔬和其他部分农产品等)药物残留检测领域中的研究现状,并针对当前农产品药物残留检测的发展趋势进行前景展望。

Application of Raman spectroscopy technology in detection of pesticide residues in agricultural products

In recent years, the excess of drug residues in agricultural products has caused a series of food safety problems, in order to ensure national food safety and protect consumer health, it is necessary to carry out qualitative and quantitative detection of drug residues in agricultural products. Surface-enhanced Raman scattering(SERS) is an attractive tool for highly sensitive detection of pesticides residue. This paper introduces the general situation of surface-enhanced Raman spectroscopy technology, describes the surface-enhanced Raman substrate, analyzes the current research status of surface-enhanced Raman spectroscopy technology in the field of drug residue detection in drug standard solution, agricultural products (such as meat, aquatic products, fruits and vegetables, etc.) and makes a prospect for the current development trend of drug residue detection in agricultural products.
