This study examines the authenticity discrimination of the circulated honey by using stable isotope ratio methods. In the case of domestic honey, the range of δ13C for the samples labeled as pure honey was about ?27- ?21‰ at the C3 origin, and the range of that for artificial honey was over ?19‰ at the C4 origin. The range of δ13C for all imported honey was over ?27- ?23‰ originating from the C3 plant. According to the nectar-source, δ2H and δ18O for domestic honey were significantly different for 6 and 5 groups, respectively. However, we could not explain the detailed relationship as well as the geographical feature of δ2H and δ18O. The difference for δ2H and δ18O in the wide range of latitude, such as between Australia and Canada, was more or less shown. However, it was difficult to find out the trends of δ2H and δ18O for imported honey versus the geographical information in the similar latitudinal country.
