Selected Qualitatives Parameters of Monofloral Honey from The Czech Republic
 JURÁKOVÁ, Andrea
The theme of this thesis is a comparison of selected quality indicators of samples from single-flower honeys from the area of the Czech Republic and honeys from different retail chains. The theoretical part focuses on the characteristics of the individual kinds of honey and how different their composition is. There are described basic physical and chemical requirements for honey including sensory requirements which are specified in Regulation No.76/2003 Code. The practical part contains a physically-chemical analysis according to the Harmonized methods of European Honey and a sensory evaluation of selected single-flower honeys (honeydew, acacia, lime, sunflower and rape). There were analysed twenty samples of honey from Czech beekeepers and fifteen samples of honey bought in different retail chains in the Czech Republic. Subsequently, these parameters were monitored - water content and acidity. Next step was a test for evidence of disruption by starchy sugar and malt extracts. Then, sensory requirements such as colour, smell, taste and consistence were evaluated. The conclusion of the comparison of honey samples indicates that individual honey samples differed the most in the taste and smell criteria and in addition the samples were often disrupted by starchy sugar and malt extracts. The samples collected from the beekeepers from the area of the Czech Republic complied with Regulation No.76/2003 Code. On the contrary, the samples from the chosen retail chains in the Czech Republic weren't in accordance with the criteria specified in Regulation No.76/2003 Code.

General parameters of honey quality and analytical methods for their determination
 DOSTÁLOVÁ, Stanislava
The topic of this diploma thesis is to evaluate the impact of grazing on the quality of bee honey. The theoretical part focuses on the characteristics of the individual kinds of honey and their different compositions. The fundamental physical and chemical requirements for honey are described there, including a sensory requirement, which indicates Public Notice No. 76/2003 Coll. The practical part contains the physico-chemical analysis itself, according to the Harmonised methods of the European Honey. The two fundamental kinds of honey were evaluated, i.e. blossom and honeydew honey. Each type of honey was represented by 20 samples. Subsequently, the following parameters were monitored: water content, acidity, pH, electrical conductivity, content of water-insoluble substances and also the test for the evidence of damage of honey structure by starch syrup was done. The comparison of the samples shows that the different types of honey vary mostly in the parameter of electrical conductivity. The final results show that the different bee grazing does not impact the quality of honey.
