Abstract:
In this research, Liquid Chromatography - Isotope Ratio Mass Spectrometry (LC-IRMS) was applied toDetermination of honey adulteration by testing the value of δ13C of a variety of sugar components in honey. After the multiple comparisons of the measurements and the collection of plates of 3 kinds of syrup, doped molasses and pure honey, it was found that doped molasses could not be used to identify honey adulteration by only using Elemental Analysis-Isotope Ratio Mass Spectrometry (HT-IRMS).However, the 3 kinds of doped molasses could be measured effectively by the method of HT-IRMS combined with LC-IRMS. The technology enriched the identification method for adulterated honey.
