Determination of hydroxymethylfurfural in honey
Dohnalová, Barbora ; Slavíková, Zuzana (referee) ; Diviš, Pavel (advisor)
Honey is a valuable food of a natural nature that can be subject to adulteration for higher profits. One method of detecting this adulteration may be to determine hydroxymethylfurfural, the formation of which is promoted by heating. The theoretical part of the thesis deals with the types of honey, their origin, and the possibilities of their falsification. HMF, its occurrence and use and methods for its determination are also described. The practical part is devoted to the description of the experiment such as sample preparation, measurement and evaluation. The HPLC (high performance liquid chromatography) method was used to determine HMF in honey, which can be used to determine even very low concentrations. There were five samples for the experiment, four of them directly from the beekeeper and one from the retail chain. All samples were compared for HMF content. The highest concentration of HMF was determined in a sample of commercially available honey. In domestic honeys, the HMF content increased with the age of the honey. The content of HMF in all honeys complied with Decree No. 76/2003 Coll.

Possibilities of using fish meat in the production of pates
Dohnalová, Barbora ; Szotkowski, Martin (referee) ; Mikulíková, Renata (advisor)
The thesis focuses on the possibilities of using fish meat in the production of pates. The aim of the thesis is to create a sensory acceptable pate with the addition of fish meat. During the development of the recipe, various concentrations of fish meat, additives, and different types of fish were evaluated. Three types of fish were selected for the pate production - carp, pike perch and mackerel. The produced pates were subjected to sensory and chemical analysis. In the sensory analysis, it was found that evaluators who do not regularly consume fish meat were more sensitive to its characteristic taste. Mackerel was the best-rated fish both in terms of the middle concentrations of fish meat and overall evaluation of all pates. The fat content analysis confirmed a lower presence of free fat in pates with the higher addition of fish meat. The nitrogen content analysis in pates confirmed that the presence of crude protein in pates increased with increasing amounts of fish meat. The pate containing only pork meat had a similar crude protein content as the pates with the addition of fish meat. The determination of the fatty acid profile confirmed a lower content of saturated fatty acids in pates with fish meat compared to pork pate. Gas chromatography-mass spectrometry in the mackerel pate revealed a substance called pristan, which is also found in other marine organisms. The conclusion of the thesis is devoted to a detailed description of the achieved results and their discussion. The results of the thesis may be useful for the food industry to expand the range of products containing fish meat.
