Honey samples named Kamennnyi (Stony) honey originated from two countries: Kazakhstan and Kyrgyzstan. Sample from Kazakhstan was collected in 2016 in Turgen region and the sample from Kyrgyzstan was collected in 2016 in Issyk-Kul region. pH measurements were detected using a digital pH meter 827 pH lab by Metrohm (Germany). pH of a 10% honey-water solution was measured and the pH was read directly from the pH meter, which was calibrated with a standard buffer solution. Results Results were done in three replicates, where was calculated the average and the analyzing was done at the room temperature (25 °C). From the following table can be seen results of analyzed honey samples, where the results were close to each other.

The mean of pH of honey samples (mean±SE). Discussion From the results of analyzed honey samples we can tell that the same type of honey from different countries can have the similar pH. Obtained results means that these types of honey have high pH and because of this reason can saccharite quickly. References 1. Bogdanov S., Ruoff K., Persano Oddo L. 2004.
