Sažetak

In this study, a total of 227 honey samples of varying types were collected from different areas in Croatia. All samples were subjected to pollen analysis and assorted into several groups including rare honey types such as amorphous, sunflower, Christ’s thorn, bearberry, heather, mandarin, willow, goldenrod, lavender, sage, rape and hawthorn. The following groups of honey were also analysed: acacia, floral, chestnut, meadow, lime, honeydew. The following physicochemical properties were tested: electrical conductivity, diastase number, water content and hydroxymethylfurfural content. All samples met the criteria for moisture content (< 20%) and ranged from 14.1% to 20.0%. Hydroxymethylfurfural concentrations ranged from 0.1 to 62.1 mg/kg and two samples did not meet the prescribed value (< 40 mg/kg). Electrical conductivity ranged from 0.10 to 2.16 mS/cm. Increased conductivity was determined for chestnut and honeydew honey, with average values of 1.33 and 1.14 mS/cm, which meets the requirements (> 0.8 mS/cm). In all other honey types, except lime, heather and bearberry, values must be below the prescribed 0.8 mS/cm, and only two samples did not meet the prescribed criteria. The lowest mean conductivity of 0.10 mS/cm was determined for acacia honey.
