Preparation of natural food supplements for children's nutrition
Kubisová, Petra ; Němcová, Andrea (referee) ; Skoumalová, Petra (advisor)
The presented diploma thesis is focused on complex characterization of chosen superfoods and subsequent composition of supplement suitable for children´s nutrition. Different kinds of superfoods were chosen for analyses, such as: barley grass (Hordeum vulgare), wheat grass (Triticum aestivum), moringa (Moringa oleifera), matcha tea (Camellia sinensis), microalgae chlorella (Chlorella pyrenoidosa), spirulina (Arthrospira platensis), flax seeds (Linum usitatissimum) and sesame seeds (Sesamum indicum). The theoretical part is focused on children´s nutrition issue and the most common food allergies and intolerances. Also, children food products legislation and characterization of chosen samples are included in theoretical part. Main macronutrients, such as saccharides, lipids and proteins, were analysed in the very beginning of experimental part. Fibre, fructan and -glucan, which have a high impact on intestinal microbiome and whole process of digestion, were analysed as well. However, barley grass was the best evaluated sample by containing 205,5 mg/g of insoluble fibre; 152,57 mg/g of fructans and 18,76 mg/g of -glucans. Finally, for complex nutritional profile, also samples pigments were analysed. Spectrophotometry, HPLC chromatography, gas chromatography and other analytical techniques were performed for experiments.
