[Application of Raman spectroscopy technique to food quality and safety determination]

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.
