Mass spectrometry is used to determine the 13C/12C ratios in honey products. The 13C/12C ratios in domestic and imported honeys are sufficiently consistent and different from those of high-fructose corn sirups (HFCSs) so that the presence of added HFCS in honey can be demonstrated. Average values of .delta.13C of -25.4.permill. (parts per thousand) for 119 honey samples and -9.permill. for 4 HFCSs were found. .delta.13C values of mixtures are the weighted sum of the .delta.13C values of the components. In a collaborative study, 4 honey-HFCS mixtures and 1 pure honey sample were correctly identified by 6 laboratories. the method was adopted as official 1st action.
