The range in the δ 13C index of the most important Spanish honeys and its protein fraction is determined by use of stable carbon isotope ratio by mass spectrometry. A variation between -27.7‰ ( Lavandula stoechas L.) and -23.7‰ (Citrus spp.) is detected, with only 1.4 units of variation in polyfloral honeys. This parameter allows to detect in honey the presence of isomerized high-fructose corn syrups.
