Využití náhradních sladidel v nealkoholických nápojích a jejich vliv na senzorickou jakost
TOLKNEROVÁ, Denisa
The subject of this thesis was to evaluate the use of sweeteners in a selected group of soft drinks from the viewpoint of the sensory quality. Using selected methods of sensory analysis were evaluated four samples of soft drinks with lemon flavor. The first sample A - Sprite contained aspartame, acesulfame K and fructose - glucose syrup. The second sample B - Slice consisted of the aspartame and acesulfame Ksweeteners. Sample C - Lemon contained only sugar and last sample D - Santerre, was composed of aspartame, acesulfame K and sodium saccharin. The evaluators were divided into two groups according to age. The first group of respondents was composed of students from the University of South Bohemia in the age of 18-27 years. The second group was composed of randomly selected people aged 40+. The aim of the thesis was to determine whether there is a disparity between the groups. Top rated sample became the sample A - Sprite. Differences occurred in sample B and C. Sample B which contains aspartame and acesulfame K was preferably evaluated bythe first group, whereas the second group consisting of older respondents evaluated preferably sample C Lemon. Lemon sample contains only sugar and its taste is therefore less noticeable or even perceived as without flavour, based on the evaluated results.The lowest rated sample was unambiguously sample D, which contains sweetener aspartame, acesulfame K and sodium saccharin. Part of this work was a questionnaire for consumers.Its main aim was to find out what mostly influences respondents when buying soft drinks, what attitude artificial sweeteners they have and if they find the composition of soft drinks determinative.

Special requirements canistherapeutic dog during his training
TOLKNEROVÁ, Denisa
The thesis is focused on the process of training of a dog, with subsequent completion of canistherapeutic exam, and deployment of the dog to his duties. Since the dawn of man, dogs helped man with various tasks. As the knowledge of dogs progressed, there were attempts to employ it for therapeutic purposes. Dogs began to take on their function as assistants to handicapped patients. With this function, the universal method of canistheraupetic training began to be implemented. The basis of this training is to expose the dog to situations, where its ability and willingness to cooperate with both the trainer and the client would become clear. 8 races were studied, 4 retrievers and 4 terriers. It was examined, how each race would be compatible with canistherapy training. Specifically the willingness to cooperate with the owner, the reaction to other dogs, other persons, and special situations. Based on the observation it was found, that terriers have encoded a strong trait of dominance in them, which has reflected on their response to the training. One of the interesting facts found is that otherwise peaceful races, such as retrievers, have shown aggression towards other dogs. This could have been caused by the fact, that these dogs do not have a traceable pedigree, and thus there were traits inherited, which would not be a part of a controlled pedigree.
