This bachelor thesis deals with food supplements, mineral elements and their determination in dietary supplements. The aim of this thesis was to elaborate a literature review focused on the food supplements, mineral elements, which are used in food supplements, and methods for determination of mineral elements in nutrition supplements. Forepart of this bachelor treats of food supplements, their basic categories, mineral elements which are contained in nutrition supplements and their effects in case of their oversupply (at high doses) or lack (at low concentrations) in a human body. Other part of this thesis is concerned with options of mineral elements determination in food supplements. Thereinafter, the thesis deals with ways of preparing samples for determination and analytical methods which are used for determination of mineral elements in nutrition supplements. Food supplements are foodstuffs which serve to direct consumption. Supplements differ from casually foodstuffs by high contents of vitamins, mineral elements and others matters which have nutrition and physiological effect. Food supplements are manufactured in order to achieve a diet completion of common user with positive impact on human health.

Probiotic foods
Páterová, Alena ; Navrátilová, Jana (referee) ; Vítová, Eva (advisor)
This bachelor thesis summarizes the knowledge about problematic of probiotics and their positive effects on human health. Probiotics are live microorganisms, which, at application in appropriate quantity as component of food, have health benefit in humans and animals. Probiotics are already an important component of treatment in gastroenterology, in hepatology, at treatment of urogenital system, at prevention and therapy of cancer and mycoses. The best known probiotics are lactic acid bacteria, of which most often used are Lactobacillus and Bifidobacterium genera. Lactic acid bacteria because of their unique metabolic characteristics are involved in many fermentation processes of milk, meat and vegetables. We can say, that advances in probiotic bacteria research are beneficial for both the consumers and the producers.

Methods for Elemental Speciation of Arsenic Compounds.
Navrátilová, Jana ; Jarošová, Alžběta (referee) ; Golian,, Jozef (referee) ; Šimko, Peter (advisor)
Speciační analýza arsenu v různých matricích s využitím HPLC/ICPMS byla předmětem této práce. Toxicita arsenu závisí na oxidačním stavu a formě, ve které je přítomen. Znalost zastoupení specií arsenu je nutná k hodnocení toxicity a biodostupnosti. Obecně, anorganické specie jsou více toxické než organické. V práci byla studována degradace arsenocukrů v mořských řasách za simulovaných přirodních podmínek. Původní arsenocukry byly transformovány na arseničnan a kyselinu dimethylarseničnou. Arsen vstupuje do rostlin z půdy a vody a následně může vstoupit do potravního řetězce. S ohledem na tuto skutečnost byla speciační analýza provedena u vybraných vzorcích rýže, zakoupených v české obchodní síti. Stanovený celkový obsah arsenu se pohyboval v rozmezí 36.06 µg/kg - 218.11 µg/kg a hlavními speciemi byla kyselina dimethylarseničná a anorganický arsen (54-78%). Mořské ryby a tuky obsahují významnou část arsenu ve formě zvané arsenolipidy. Část práce byla zaměřena na analýzu arsenolipidů u máslové ryby (Lepidocybium flavobrunnrum) s celkovým obsahem arsenu 1.8 mg/kg a 22% celkového arsenu bylo vyextrahováno pomocí hexanu, což potvrzuje lipofilni charakter těchto sloučenin. Hlavní specií stanovenou ve vodném extraktu byl arsenobetain, představující 89%.

Microbiology of wine
Valicová, Markéta ; Navrátilová, Jana (referee) ; Omelková, Jiřina (advisor)
The aim of this work was the investigation of the amount and the composition of microflora during the winemaking of red wine. The study was performed in 3 factories in Velké Pavlovice region, where each of them utilized its own technological approach. According to this, during the period of preliminary fermentation, 3 different technological procedures were used, which differed in application of commercial yeasts and enzymes, and sulphur dioxide. They differed also in the temperature during the period of alcoholic fermentation and the application of commercial bacteria during the period of malolactic fermentation. From the experimental results follows that the application of different technological approaches leads to the differences in the number of both yeast and bacteria viable cells and the total number of microorganism cells in the period of preliminary, alcoholic and malolactic fermentation.
