This bachelor thesis deals with the current issue of processing blood into meat products, which originates in history, but the essence remains the same. The use of blood in meat products tends to decrease. Mostly because of its poorer endurance and diminishing popularity with consumers. It describes the slaughter of the animal and the processing of blood for food and other purposes. Furthermore, the work describes the use, composition and properties of the blood. Blood has a similar protein content compared to meat, mainly has a high biological value and contains iron as well as other minerals that contribute to human health. There is also the risk of an alimentary risk, which is part of all meat products. In the next part, meat production, the distribution of meat products and, above all, the list of blood meat products and their recipes are distributed. Also described here is the issue of regional food in selected countries, traditional meat products and domestic slaughter of pigs.

Voltammetric Determination of Nimesulide Using Graphite Composite Electrode
Hubáčková, Monika ; Vyskočil, Vlastimil (advisor) ; Fischer, Jan (referee)
This Diploma Thesis deals with the study of the electrochemical behaviour of the nonsteroidal anti-inflammatory drug nimesulide. The aim of this work is to find optimal conditions for the determination of nimesulide using voltammetric techniques direct current voltammetry (DCV) and differential pulse voltammetry (DPV) in oxidation and reduction potential regions. An ultra-trace graphite electrode (UTGE) was used as the working electrode. The pH dependence was measured to select the optimal pH, the probable mechanism of reactions was determined, the repeatability of the measurements was checked, and finally the calibration dependences were constructed and evaluated in the selected media. BR buffer media of pH 2 and 4 for DCV and pH 2 and 5 for DPV were selected to measure calibration curves in the concentration range of 0.1-100 µmol L−1 . The detection limits for both methods DCV and DPV at the UTGE were in order of about 10−7 mol L−1 , which are values corresponding to alternative voltametric methods that also use unmodified working electrodes.
