Valentová, Radka ; Starečková, Terezie (referee) ; Márová, Ivana (advisor)
Presented bachelor thesis is focused on study of biologically active substances in cereal products. In theoretical part over view of cereal active substances, predominantly phenolic compounds were introduced. In practical part 15 kinds of cereal products were analyzed. In these materials some group parameters - total phenolics, total flavonoids and total antioxidant activity were measured by spectrophotometry. RP-HPLC/UV-VIS method was performed for analysis of selected individual flavonids. The highest content of phenolic compounds was measured in cereals containing fruits (raspberries, blueberries, tropical and red fruit), cacao, crusty fruits (hazel nuts, sunflower seeds) and buckwheat. All cereal products contain catechine, epicatechine, catechin gallate, epicatechin gallate, chlorogenic and ferulic acid. As a part of bachelor thesis simple sensory analysis was performed and consumer questionnaires were evaluated.

The structure of supply and costs of cereal biofood in the selected region of the Czech Republic
JIŘÍKOVÁ, Martina
The aim of this bachelor thesis was to evaluate the structure of the supply of organic cereals in the town Sušice. Comparison of the supply of organic cereals was made in different types of supermarkets (Billa, Albert, Penny, Lidl, Tesco and Coop) and in one specialized shop (Meduňka). The differences between the prices of organic and conventional cereal food were evaluated. The survey was conducted during six months, from November 2011 to March 2012. In total, 82 organic cereals were found, most of them were available in Meduňka specialized shop (37). The differences between the prices of organic and conventional cereal foods were significant. For example, in the prices of muesli bars and rice sandwiches, a survey has found that organic prices were 50 to 100 % higher. If someone bought one piece of all the organic cereal food in Sušice, he would pay 1152 CZK. The purchase consisting of one piece of adequate conventional product would cost 760 CZK. It means, that to buy organic products would be more expensive (76 %). It was also concluded, that the supply of organic food in Sušice was lower than the Czech Republic?s supply.
