    Physicochemical properties of 27 sunflower honey samples from Bulgaria were investigated. The botanical origin of the samples was ascertained by pollen analysis. The honey samples displayed relative frequencies of Helianthus annuus L. pollen up to 41%. The ranges for water content (15.60– 19.30%), reducing sugars (72.51–80.80%), sucrose (0.50–3.70%), diastase (9.00–20.80 Gothe units), hydroxymethylfurfural (HMF), (0.69–12.40 mg/kg), total acidity (17.70–36.00 meq/kg), electrical conductivity (0.23–0.48 mS/cm), proline (218.50 – 679.50 mg/kg), specific rotation (-20.20–(-12.30)) [α]D 20 were obtained. The results obtained also suggest that these honey samples are of good quality. The results are in agreement with standards of quality established by national and international regulations. Significant moderate correlation between electrical conductivity and specific rotation was found (r=0.582, p<0.05).
