Abstract:
The authors developed a rapid analytical method that could determine the PAHs in food samples simultaneously by the coupled approach of Shpol' skii spectroscopy and constant-energy synchronous fluorescence scanning technique. Low-fat food samples, which were just extracted with octane and high-fat food samples pre-processed with saponification and extracting, could be analyzed immediately. The recoveries ranged from 80.2% to 98.9% and the correlation coefficients of the linearity were higher than 0.993 8. This method was selective, simple, rapid and inexpensive.
