Abstract

Gacka region and northern slopes of Velebit are typical mountain meadow honey areas. Bees pasture is relatively stable, almost evenly distributed throughout the years. The aim of the research is to determine the characteristics of multi-floral honey in the Gacka region based on mellisopalinological and physicochemical analyses. In order to collect honey samples from Gacka region, honey competition was organized in 2008, 2009 and 2010. A total of 68 samples of honey were collected. According to botanical origin in 2008, 12 samples of floral honey, 1 meadow and 6 samples of honeydew honey were determined. In 2009 from total of 25 samples of honey, 7 samples were determined as floral honey, 6 meadow, and 12 samples as honeydew honey. From total of 24 samples of honey in 2010, 5 were determined as floral honey, 16 samples as meadow honey, 2 as sweet clover (Melilotus spp.) and 1 sample as Dorycnium (Dorycnium spp.). Water content in the studied honey samples ranged from 14.60 to 18.20% with a mean value of 16.32%. Floral honey samples from 2009 and 2010 had a higher pH values (4.97, 4.83) compared to the samples from 2008 when the value was 4.68. In the investigated samples of floral and meadow honey the share of reducing sugars ranged from 55.31% in 2008 year to 77.02% in 2010. Honey types were separated on the basis of physicochemical parameters using Canonical discriminant analysis. The strongest influence on honey type discrimination had electrical conductivity, HMF, acidity together with characteristic pollen spectrum and sensory properties.
