Prachárová, Adriana ; Vysoká, Marie (referee) ; Márová, Ivana (advisor)
This bachelor thesis deals with properties of selected fruits and seeds of superfoods, the introduction of their biologically active substances and comparison of their nutritional properties. The theoretical part focuses on characterizing the fruit itself (pineapple, banana, blueberry, kiwi, raspberry and orange) and seeds (chia seeds, poppy seeds and almonds). It is focused on characterization of bioactive substances contained in them, such as polyphenols, flavonoids, antioxidant activity, vitamin C, vitamin E and fatty acids. Further, used methods are described. In the experimental part, the content of the antioxidant activity and biological effects in selected fruits and seeds was measured and concentrations was calculated per 1 g of dry matter. Finally, a sensory analysis consisting of eighteen fruit and seed combinations is introduced. The aim of the thesis was to find out which of tested combinations are nutritionally high and, simultaneously, acceptable for consumer.
