Honey is a natural sweet substance made by Honeybees from the nectar of flowers which is

often adulterated using cane sugar, beet sugar, Jaggery and High fructose Corn syrup (HFCS) for economic benefits. In this study, fluorescence properties of Honey and Jaggery syrup were examined in order to detect jaggery adulteration in Honey. Honey samples were adulterated with 40% Jaggery syrup in five different concentrations (5% - 25%) and analysis was done using fluorescence spectrophotometer at room temperature. The Pure honey sample and jaggery syrup were scanned at excitation of 400nm (emission: 430-700), 410 nm (emission: 450-650), 420nm (emission: 500-650). Both Honey samples and jaggery syrup show different peaks according to their dominant fluorescent molecules in

(480-500nm) and (560-580nm) range respectively. So the ratio of fluorescence intensities of two peaks can be used for monitoring jaggery adulteration of honey. This was done by scanning all the samples for Synchronous luminescence spectra which simultaneously scan both excitation and emission monochromator at the same speed at a wavelength interval of ( δλ=40nm ) and results were analysed. The spectra for pure honey and jaggery syrup were observed at 458 and 561nm. As the concentration of jaggery syrup increases in Honey, there was a peak shift observed towards jaggery syrup spectra. So the difference in synchronous luminescence spectra of Honey and Jaggery syrup could be used for detecting adulteration of Honey.
