Možnosti výroby piva z netradičních surovin
Valentová, Natalie
The literary part of the diploma thesis deals with traditional raw ma-terials, special malts and non-traditional raw materials for beer producti-on and beer production as such. Furthermore, the production of beers from non-traditional raw materials in the world. The experimental part is devoted to the description of the production of own beers from non-traditional malts (amaranth, chickpeas, sorghum, buckwheat, quinoa) and their chemical analysis by HPLC and Fermen-toFlash. In the next part a method of sensory analysis was described, and the results were then shown using radar charts. In the results and discussion section these analyzes are statistically processed and evaluated for the mutual dependence of the substances from the chemical analysis on the sensory characteristics of the individu-al products.

The rutin content in amaranth (Amaranthus sp.)
BERANOVÁ, Kristina
This work was aimed to the determination of the flavonoids of rutin in the leaves, stems and seeds of different kinds and species of amarant. Rutin is a phenolic substance, which belongs to big group of secondary plant metabolites. Most recently lot of attention is paid to quercetin and its glycoside {--} rutin because of its demonstrable positive effect on the human organism, mainly the antioxidant effects which prevents the atherosclerotic plaque and preroxidation of lipids and antiviral activities. The research orients to its potential anti-carcinogen activities. Thanks to these properties it became a common part of the human daily diet. Amarant could be a beneficial source of these substances. Content of rutin was determined by the micelar electrokinetic capillary chromatography (MECC) in the group of seven genotypes of amaranth. For the analysis a samples of leaves, stems and seeds were used, because of its high contents of flavonoids. The highest content of rutin was found in the leaves of the species A. cruentus {--} genotype Olpir (27 400 mg/kg of dry matter) and the lowest in the seeds of A. cruentus {--} genotype Monatana (25,3 mg/kg of dry matter). Results of this research are unique as they were never published before.
