Abstract: Making an effective detection method on honey adulteration detection was of important practical significance on monitoring the honey industry. In order to achieve the rapid detection of honey mixed with high fruit syrup， the glass transition temperature Tg of linden honey mixed with different contents of high fructose syrup was determined by differential scanning calorimetry （DSC）. The results showed that the pure linden honey and high fructose syrup had significantly different glass transition temperature， whose Tg values were -5545℃ and 6086℃， respectively. When the content of high fructose syrup was lower than 10%， the Tg values of the adulterated honey and pure linden honey was too close to distinguish. When high fructose syrup content was higher （20%， 40%， 80%）， there was a good linear relationship between high fruit syrup quality score and the Tg values of doping honey. In conclusion， the identification of the contents of the doped high linden honey based on the differential scanning calorimetry is feasible.
