    Dried tangerine peels stored for eight different periods were measured by surface-enhanced Raman spectroscopy. Raman spectra on gold film substrate, silver nanoparticle substrate and gold film-silver nanoparticle substrate of dried tangerine peels stored for 11 years were detected and analyzed School. Raman spectra of dried tangerine peels tested on gold film-silver nanoparticle substrate show the most obvious Raman characteristic lines. 12 Raman characteristic peaks at 375, 493, 650 cm-1, etc. were initially assigned, which gave an experimental evidence to judge the biochemical components of dried tangerine peels. Probable enhancing mechanism of the Raman signal of dried tangerine peels on gold film-silver nanoparticle substrate was discussed. By comparing and analyzing the surface-enhanced Raman spectral information, dried tangerine peels of different storage periods were distinguished. According to the Raman spectral information of the eight samples, a conclusion can be drawn that the dried tangerine peels stored for more than 7 years (including 7 years) produce some new components compared with the dried tangerine peels stored for less than 5 years (including 5 years).
