Mikroskopie medu a ověření jejího potenciálního významu pro zkoušení medu
Ležatka, Michal
This thesis deals with the microscopic analysis of honey and its use in the evaluation and testing of honey. The work is divided into theoretical and practical parts. The theoretical part is devoted to the analysis of pollen and physical and chemical methods of determining the type of honey. The practical part describes the results and compares them. 22 honey samples originating from beekeepers has been shown 17 beekeepers false claims about their type of honey. Of the 7 aldulterated honeys, 4 samples were violated by foreign particles from the environment. Further honeys from the market containing suspicious particles and very critically low pollen grains in 1 g of honey, which points to a adulteration of honey. Unifloral honeys from Olomouc were found honey from satureja (S/2) and lavandula (F/1) containing neither one pollen grain of these plants.
