Abstract:
      A rapid analytical method was developed for the determination of saccharin sodium salt in dry fruits by surface-enhanced Raman spectroscopy(SERS).The saccharin in real samples was extracted with water, followed being separated and cleaned up on the activated C18 solid phase extraction column before surface-enhanced Raman scattering measurement.The linear range of this method was from 50.0 mg/L to 250 mg/L,and the detection limit was 0.6 g/kg.The good recoveries were in range of 80.0%-125% with relative standard deviations(RSD,n=5) no more than 8.4%.The results suggested that this method, with good anti-interference capability, was sensitive and reliable in the rapid determinattion of saccharin sodium salt in dry fruits.It is expected that this SERS based rapid analytical method possesses a great potential in monitoring the quality of dry fruits.
