Vliv podmínek skladování na mikrobiologickou kvalitu potravin živočišného původu
Krcháková, Kateřina
This work deals with the issue of microbiological degradation of food of animal origin depending on environmental conditions, which can inhibit or support the development of microorganisms. The work includes an overview of the most important microorganisms focusing on their metabolism and the principle of negative effects on food. The practical side of the thesis is based on laboratory experiments and sample analyzes of some of the most common representatives of food of animal origin – ham and hard cheese. Samples of these foods were stored in different environments and their microbiological contamination was subsequently determined. The results were processed into graphical and tabular outputs emphasizing the influence of the given environment on the level of food contamination.

Portrayal of animal products in advertising
Hamrová, Alžběta ; Rosenfeldová, Jana (advisor) ; Schneiderová, Soňa (referee)
This bachelor thesis deals with strategies and techniques used by advertisers while communicating animal products. Researching these techniques, this paper observes psychological patterns through which our society rationalises animal consumption and subconsciously separates the notion of a living animal from the portion of meat on a plate. These patterns are deeply rooted in the so-called ideology of carnism, an ideology in which animal consumption is considered ethical and acceptable. Despite the justification for animal exploitation, most consumers are sensitive to the suffering of animals, which must be taken into consideration advertisers. Based on case studies of the campaigns Got milk, Vodňanská drůbež and S láskou k mléku, techniques are identified through which these products are communicated in order to make them acceptable by society. While studying these campaigns, the thesis discusses three key strategies that brands use while communicating animal products: celebrity endorsement, anthropomorphisation of animals and idealisation of animal welfare. Based on these findings, we can recognise that advertisers choose certain strategies for the consumer to rationalise meat consumption, thereby contributing to the consolidation of the profitable ideology of carnism.
