  Abstract:  12 Romanian samples of honeys from different floral sources were analyzed for the determination of high fructose corn syrup (HFCS) adulteration of honey, by coupling an isotope ratio mass spectrometer to an elemental analyzer. Using the difference in stable carbon isotope ratio (δ13C) between honey and its protein fraction it is possible to evaluate the adulteration with small extent (minimum 7%). An obvious adulteration was observed for the multifloral honey, while for other 5 samples the negative difference indicated that these samples are not adulterated. For the other 6 samples, the positive difference indicates the absence of adulteration.

Keywords: honey; adulteration; carbon isotope ratio; δ13C.
