The investigations were carried out in the Honey Analysis Laboratory of Honeybee Research Institute, National Agricultural Research Centre Islamabad, Pakistan, to determine the quality and Physico-chemical characteristics of honey samples from different localities of Pakistan. Physicochemical analysis of these samples was carried out using AOAC methods and Harmonised methods of International Honey Commission and results were compared with the standards of Codex Alimentarius and European Union Council Directive. The range of different parameters was 18.00±0.10-23.50±0.30% moisture, 3.67±0.006-7.07±0.006 pH, 8.03±0.35-35.66±2.51meq/kg acidity, 6.76±0.05-7.90±0.10% sucrose, 75.00±0.20-81.00±0.10% total sugars and 0.11±0.01-0.92±0.01 mS/cm electrical conductivity, 0.01±0.003 -0.26±0.004% ash. Values for sucrose, acidity, total sugars and ash were within the normal ranges except for the moisture, pH and electrical conductivity. These parameter’s values were found higher than the recommended ranges. One sample LB-19 had the highest value of 23.5±0.30% for moisture and 0.92±0.01mS/ cm for electrical conductivity, while LB-20 had the highest value of 7.07±0.006 for pH.
