[Objective]The aim was to explore application of LC-IRMS technique in identification of honey adulteration. [Method]We detected 62 honey samples by LC-IRMS,and determined δ~(13)C value of fructose,glucose,disaccharide and trisaccharide of honey. [Result] The difference of maximum and minimum δ~(13)C of fructose,glucose,disaccharide and trisaccharide of true honey was less than 2. 1‰,and δ~(13)C Fru-δ~(13)C Gluwas from-1‰ to 1‰,and there was no oligosaccharides,so 48. 38% of samples was no qualified.
