    In this study, 23 honey samples collected from South-Eastern Anatolia Region of Turkey were investigated to identify their botanical sources. According to the microscopic analysis results, pollen grains identified belong to the 24 taxa of 27 plant families. As a result of melissopalynological analysis, 21 of the honey samples are characterized as multifloral and two of them are as unifloral (Myosotis honey). As the second step of the microscopic analysis, the total pollen number of in 10 grams honey (TPN10) of the samples were calculated and it was observed that the values were vary between 1 177 and 82 005.

    Melissopalynology analysis, physicochemical properties, multi-element content and antimicrobial activity of honey samples collected from Bayburt, Turkey
    (Bursa Uludağ Üniversitesi, 2019-10-14) Bayram, Nesrin Ecem; Yüzer, Mustafa Onur; Bayram, Sinan
    The aim of this study was to determine the plant sources, physicochemical properties, element content and antimicrobial effects of honey samples collected from 10 different regions of the province of Bayburt, Turkey. The melissopalynological analysis showed that the pollen samples of 67 plant taxa belonged to 34 plant families in honey samples and were found with different rates and TPN-10 values was found between 16024 and 90126. In addition to these, the amount of ash was between 0.13% and 0.32%, the electrical conductivity value was between 0.36 and 0.69 mS/cm, the moisture content was between 16.1% and 18.9% and the fructose/glucose ratio was between 0.92 and 1.18. As a result of physicochemical analysis, it was determined that the data obtained were in compliance with the standard values defined in by the Turkish Food Codex Communiqué on Honey (No: 2012/58). Elemental analysis performed with ICP-MS showed that the K element was the highest (261.34-1863.05 mg/kg) in all honey samples in total among the 42 elements. In addition to these, the antimicrobial effects of honey samples and minimum inhibition concentration values (MIC) were determined by the agar well diffusion (AWD) method and and microbroth dilution method respectively.
