Abstract :This study presents physicochemical characteristics of 39 honey samples (21 blossom and 18 pine honey) collected during two years from three different geographical regions of Türkiye that differs vastly in climatic conditions and thus plant species. The samples were analysed for δ13C/δ12C stable carbon isotope ratios of honey (δ13Ch) and its protein fraction (δ13Cp), moisture, free acidity, proline and 5-hydroxymethyl furfural (HMF) content, diastase activity and sugar composition. The results showed that C4 sugar content, proline content, diastase activity, acidity values of pine honeys were higher than that of blossom honeys whereas, higher moisture and HMF content were detected for blossom honeys. Besides, geographical region mainly affected the moisture and C4 sugar contents. High correlations between HMF and δ13Ch and δ13Cp; proline and acidity values; fructose and glucose content were determined, and this indicated the robustness of the analysis and quality evaluation among different honey types and regions.
