Some physiochemical properties of Acacia honey from different altitudes of the Asir Region in Southern Saudi Arabia

Abstract

The physiochemical properties of six Acacia honey samples taken from three different altitudes in the Asir region were determined. The means of all the studied parameters were within the international standards and were comparable to previous studies (0.11 ± 0.08% for ash, 10.93 ± 1.97% for water, 3.56 ± 0.19 for pH, 38.63 ± 17.17 meq/kg for acidity, 659.51 ± 324.98 μS/cm for conductivity, and 1.45 ± 0.02 for specific gravity). Comparison of the mean values of the parameters at the different altitudes revealed gradual increases with increasing altitude, except for ash and specific gravity. Significant differences were seen in ash and water percentages, acidity, and conductivity. While the mean values of the studied physiochemical properties of the Acacia honey samples were within the ranges of international standards, the honey produced at high altitudes exhibited variable physiochemical properties.
