            Application of Raman spectroscopy technology to studying Sudan I

            【摘要】Being an industrial dye, the Sudan I may have a toxic effect after oral intake on the body, and has recently been shown to cause cancer in rats, mice and rabbits. Because China and some other countries have delected the Sudan I in samples of the hot chilli powder and the chilli products, it is necessary to study the characteristics of this dye. As one kind of molecule scattering speclroscopy, Raman spectroscopy is characterized by the frequency excursion caused by interactions of molecules and photons. The frequency excursion reflects the margin between certain two vibralional or rotational energy states, and shows the information of the molecule. Because Raman speclroscopy can provides quick, easy, reproducible, and non-destructive analysis, bolh qualitative and quantitative, with no sample preparation required, Raman speclroscopy has been a parlicularly promising technique for analyzing the characteristics and slruclures of molecules, especially organic ones. Now, it has a broad application in biological, chemical, environmental and industrial applications. This paper firstly introduces Sudan I dye and the Raman spectroscopy technology, and then describes ils application to the Sudan I. Secondly, the fingerprint spectra of the Sudan I are respectively assigned and analyzed in detail. Finally, the conclusion that the Raman spectroscopy technology is a powerful tool to determine the Sudan I is drawn.
