Pollen analysis of honeys from Varaždin County, Croatia

The palynological properties of 8 honey samples commercially produced in 1 region in Croatia (Varaždin County) were determined. Each sample was examined to determine the pollen percentage and pollen spectrum. On the basis of honey pollen analysis, in these 8 samples different botanical origin was determined. | M. SABO, M.

Each sample was examined to determine the pollen percentage and pollen spectrum. On the basis of honey pollen analysis, in these 8 samples different botanical origin was determined. In total, 20 different types of pollen grains were identified. The dominant group of pollen grains consisted of Castanea sativa Mill. in samples 2 and 8, Brassica napus L. in samples 4 and 5, and Trifolium pratense L. in samples 6 and 7. The pollen analysis revealed 6 unifloral and 2 multifloral honeys. Analysis was performed using methods in accordance with national and international legislation, in an accredited laboratory. Key words: Pollen, honey, unifloral honey, multifloral honey Introduction Melissopalynological analysis is still the prescribed method for botanical origin denomination and therefore it is one of the greatest discriminatory powers of honeys (Ruoff & Bogdanov, 2004). According to some authors, not only are acidity and humidity especially important parameters, but in some cases pollen analysis is also of great meaning for the geographical origin and classification of honeys (Persano Oddo & Piro, 2004a; Kaya et al., 2005; Silici & Gökçeoğlu, 2007), particularly when an individual floral species is growing in specific areas (Anklam, 1998). As emphasised by Mandić et al. (2006) there are more than 100 unifloral honeys in Europe, but most of them are produced .
