摘要
拉曼光谱技术具有样品无需前处理、操作简便、时间短、灵敏度高等优点,可获得样品的物理化学及深层结构信息,已广泛应用于石油化工、生物医学、地质考古、刑事司法、宝石鉴定等领域。拉曼光谱对水等极性物质极其不敏感,在食品质量安全检测方面具有良好的应用前景。论文简述了拉曼光谱技术的检测原理、分类以及系统的组成,综述了拉曼光谱技术在食品成分分析和农药残留检测中的最新研究进展,指出了该技术在食品质量安全检测中的关键技术并对今后的研究进行了展望。
With the merits of doing without sample pretreatment,easy operation,short response time and high sensitivity,Raman spectroscopy technique can acquire samples＇ physical chemistry and the deep structure information.It has been widely applied in petrol chemical,biomedicine,geoarchaeology,criminal justice,gem identification,etc.Raman spectroscopy has good application prospect in food quality and safety determination,for its spectra are not extremely sensitive to polar materials such as water.The detection principle,classification and the system composition of Raman spectroscopy technique were introduced briefly.The latest research progress in food constituent analysis and pesticide residue determination by Raman spectroscopy was reviewed.Finally,its key technologies for food quality and safety determination were pointed out and the future research was prospected.
