In all of the honey samples, the δ13C value was found to be more negative than −23.5‰ and even the C4 sugar ratio was found to be lower than 7%. The results from the physicochemical analysis of the samples were determined to be 15.9 ± 1.6% for the moisture content, 82.8 ± 1.1 for brix, 0.183 ± 0.02 mS/cm for conductivity, 24.4 ± 4.0 meq/kg for total acidity, 546 ± 80 mg/kg for proline, and 14.5 ± 3.5 for diastase activity. In addition, the sugar content was determined to be 38.8 ± 1.8% for fructose, 30.2 ± 1.7% for glucose, 69.1 ± 3.3% for fructose + glucose, and 1.29 ± 0.5 for fructose/glucose. When the analysis results were evaluated according to the relevant standards and codex, it was evident that the honey samples produced within the region are of very good quality.falseAdulteration | Carbon isotope ratio ( C/ C) 13 12 | EA–IRMS | Food analysis | Food composition | Honey | Physicochemical propertiesDetermination of the physicochemical properties and <sup>13</sup>C/<sup>12</sup>C isotope ratios of some honeys from the northeast Anatolia region of TurkeyDetermination of the physicochemical properties and C-13/C-12 isotope ratios of some honeys from the northeast Anatolia region of TurkeyArticle10.1016/j.jfca.2018.02.00710.1016/j.jfca.2018.02.0072-s2.0-85042282508WOS:0004330146000073944691096-0481
