This thesis analyses consumer behaviour connected with chocolate bars. It describes metodology of marketing research. The form of the research is questionnaire. Respondents are students of VŠE. The research discovers popularity of some brands and selling places in the campus. Results are used for the formulation of recommendation for the strategy of sale.

The aim of the diploma thesis „Raw food – raw food“ was study and describe a living diet. Describe the influence on human body and propose a suitable recipe a raw durable product. At the department of food technology, the faculty of Agronomy of Mendel university in Brno were made eight recipes of raw bars without heat, with a dates and cocoa base. For each recipe was added the third feedstock. Strength, water content, sensory evaluation and final nutritional value were evaluated. I was found that the most sensibly acceptable formulation contained coconut in addition base. Conversely, the least acceptable formulation contained a banana in addition to the base. The highest nutritional value was the bar with addition whit coconut. Next were made four dried raw bars where the sensory evaluation was statistically different among the professional public, who are interested in raw food and the non-professional public.

The aim of the thesis Technological possibilities of malted coloured wheat is to summarize information about coloured wheat, their contained substances and about their varieties, which can be used for food production and to manufacture several products from malted wheat. In the introduction of the theoretical part there are described properties of common wheat, its anatomical and chemical composition. It is focused on coloured wheat and their properties, including a description of their natural pigments. Malting process is decribed in detail. The practical part is aimed at beer, cereal milk and cereal bars production. For their production were also used common wheat, barley malt, oat and oat-flakes. The samples of product from different wheat varieties were then tested by sensory analysis. Analysis of beers and cereal milks were made by liquid chromatogramy.

The diploma thesis consists of theoretical and practical part. In the theoretical part it deals with lipids and their role in human nutrition. I also characterized fatty acids and evaluated their health effects. Subsequently, I studied the theoretical basis of chromatographic methods focusing on gas chromatography, its instrumentation and evaluation. In the practical part I analysed the selected assortment of müsli bars by several producers. I focused on the quality of some müsli bars available on the Czech market, focusing mainly on fat content and fatty acid composition. As far as preparation of samples are concerned, it was necessary to lyophilize them first and then Soxhlet extraction followed. The actual determination of fatty acids was carried out using the method of gas chromatography and the results were statistically evaluated.

Several changes in land use during the last 50 years of 20th century had a significant impact on the composition of traditional meadows. The abundance of many plant species typical for traditionally managed meadows has declined. But some of these species have found a refuge in habitats such as field margins and road verges. The aim of this study was to describe how the reproduction success of two related Achillea species A. millefolium agg. and A. ptarmica depends on (i) the particular habitat in which they grow (meadow/verge); (ii) the abundance of pollinators in the study site; and (iii) timing of flowering within the season. Moreover, the longevity of individual flowers of the two taxa has been studied in order assess the width of the time frame the reproduction takes place in. These objectives were achieved by means of measuring plant total seed production and germination as proxies of reproductive success both in meadow and verge populations at the beginning, peak and end of the flowering season of the two species in 2012. The plants were chosen at plots, where concurrently a pollinator survey has been conducted as the part of the broader project. The durations of the male and female phases of individual flowers have been studied in separate experiments.
