Surface-enhanced Raman spectroscopy (SERS) is an advanced Raman technique that enhances the vibrational spectrum of molecules adsorbed on or in the vicinity of metal particles and/or surfaces. Because of its readiness, sensitivity, and minimum sample preparation requirements, SERS is being considered as a powerful technique for food inspection. Key aspects of food-safety assurance, spectroscopy methods, and SERS are briefly discussed in an extended introduction of this review. The recent and potential advances in SERS are highlighted in sections that deal with the (a) detection of food-borne pathogenic microorganisms and (b) the detection of food contaminants and adulteration, concentrated specifically on antibiotics, drugs, hormones, melamine, and pesticides. This review provides an outlook of the work done and a perspective on the future directions of SERS as a reliable tool for food-safety assessment.

表面增强拉曼光谱技术应用于食品安全。

表面增强拉曼光谱（SERS）是一种先进的拉曼技术，可增强吸附在金属颗粒和/或表面上或附近的分子的振动光谱。由于其易用性，敏感性和最低的样品制备要求，SERS被认为是食品检验的有力技术。在本综述的扩展介绍中，简要讨论了食品安全保证，光谱学方法和SERS的关键方面。SERS的最新进展和潜在进展将在以下各节中进行重点介绍：（a）食源性致病微生物的检测和（b）食品污染物的检测和掺假，特别集中在抗生素，药物，激素，三聚氰胺和农药上。
