摘要
动物性食品安全问题日益突出,愈演愈烈,有关问题食品的报道也受到了公众的广泛关注。一旦兽药在畜牧养殖过程中被过度使用或滥用,药物残留将给人类健康带来严重危害。常见的残留检测方法存在成本高、速度慢和效率低等缺点,通常需要专业人员操作,传统的理化方法已不能满足食品质量检测的需要,因此研发快速高效的兽药残留检测方法起着关键作用。近年来,表面增强拉曼光谱(SERS)技术在真伪鉴别、非法添加物检测和农兽药残留等诸多领域得到了广泛应用,并以其快速检测、无损等优势在食品检测领域有着更为广阔的发展前景。与其他检测方法不同的是,SERS通过信号放大和高灵敏度的指纹光谱,可以快速识别目标分析物,进行定性或半定量分析。本文主要介绍了拉曼光谱和SERS在动物源性食品中兽药残留检测中的研究和应用,重点介绍了SERS的优势、食品样品的前处理以及SERS结合其他技术检测多种兽药的相关研究,并提出了SERS在实际监测中面临的挑战。
The safety issue of animal food has received widespread public attention due to increased reports of problematic foods.Once veterinary drugs are overused or abused in the process of animal husbandry,drug residues will bring serious harm to human health.Common residue detection methods have the disadvantages of high cost,slow speed and low efficiency,which usually requires professional personnel to operate,and the traditional physical and chemical methods can't meet the needs of food quality testing.As a result,the research and development of rapid and efficient detection methods for veterinary drug residues is necessary.In recent years,surface-enhanced Raman spectroscopy(SERS)has been widely used in many fields such as authenticity identification,illegal additives detection,agricultural and veterinary residues,etc,and has a broader development prospect in the field of food testing due to its advantages of fast detection and nondestructive.SERS is different from other detection methods in that it can rapidly identify target analytes through signal amplification and highly sensitive fingerprint spectroscopy for qualitative or semi-quantitative analysis.This paper mainly introduces the research and application of Raman spectroscopy and SERS in the detection of veterinary drug residues in foods of animal origin,focusing on the advantages of SERS,the pre-treatment of food samples,and the related research on the detection of a variety of veterinary drugs by SERS combined with other techniques,and proposing the challenges faced by SERS in practical monitoring.
