Laboratory for honey and other bee products analyses

Laboratory for honey and other bee products analyses is established in 2000 within the Department of Food and Nutrition Research. The initial aim of Laboratory was performance of analyses of honey for the purposes of the national contest in collaboration with the Croatian Chamber of Economy, County Chamber Osijek and Croatian Beekeepers Association. In March 2005 the Ministry of Agriculture, Forestry and Water Management appointed the Department's Food Quality Laboratory as the official laboratory for honey and other bee products analyses (N.N. 41/2005). Since then, besides performing the analyses for national contest and the beekeepers, a number of scientific research and projects have been launched within the Sub-department of Food Quality. For the last fifteen years, the scientific and professional interest of Sub-department employees is mostly related to the honey and other bee products. Through IPA project “Panonian Bee”, which was held by the Osijek-Baranja County, the Laboratory received valuable equipment that enabled a significant increase in the number of parameters analysed.
