The 13 C/ 12 C Ratio in Honey

SummaryValues of the ratio 13C to 12C are given for 84 representative honeys from the United States and 35 honeys imported into the United States. Remarkably uniform results were obtained; the average δ13C for all samples was—25·4%, and the coefficient of variation only 3·86%.The values are those expected from plants with the C3 (Calvin) photosynthetic pathway. They provide the basis for the detection of corn-derived syrups in honey.
