Annotation Pšenice je jednou z nejvíce pěstovaných obilnin ve světě a díky vyššímu obsahu lipidů je významným zdrojem energie a obživy pro obyvatelstvo. Prvním cílem diplomové práce bylo nalézt vhodnou metodu pro stanovení celkového obsahu tuku v pěti vybraných druzích pšenice. Byly proto vyzkoušeny tři metody vhodné pro stanovení tuků. V první metodě byla použita směs chloroformu a methanolu, druhou metodou byla Sxhletova ex-trakce a jako třetí byla testována ISO norma 7302. Nejpřesnější výsledky (v porovnání s deklarovanými hodnotami) byly dosaženy postupem podle metody ISO 7302. Druhá část práce byla zaměřena na zavedení HPLC metody pro stanovení cholecalciferolu. Pomocí standardu byly zjištěny optimální podmínky pro jeho stanovení, které byly při vlnové délce 265 nm a průtoku mobilní faze 0.6 ml.min-1. Retenční čas cholecalciferolu byl za těchto podmínek 6.5 - 6.6 min. Tyto hodnoty byly poté použity při vlastním stanovení cholecalci-ferolu v mléce.
Annotation in English The wheat is one of the most cultivated cereal in the world and due to the higher content of lipids, it is important source of energy and living for the population. The primarily aim of the thesis was to find suitable method for total fat content determination in five varieties of the wheat. They were tested three methods. The first one used mixture of chloroform and methanol, the second method was the Soxhlet extraction and in the third case was tested the ISO norm 7302. The most exact results (in comparison with declared values) were achieved with the procedure according to the ISO norm method. The second focus of this thesis was on preparing of HPLC method for cholecalciferol determination. They were established optimal conditions for its determination using the standard which were at the wavelength of 265 nm and at the mobile phase flow rate of 0.6 ml.min-1. The reten-tion time was 6.5 - 6.6 min. These conditions were used for cholecalciferol determination in milk.
