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.
