Analýza vybraných potravin metodou NIR
Bočková, Tereza
BOČKOVÁ, T. Analysis of selected foods by NIR, Master thesis, MENDELU in Brno, 2015, 72p. The aim of the thesis was to examine samples of regionally grown cereals, oilseeds and legumes using NIR analyzer DA 7200 and compare the results to the tables and chemical analysis. A total of 26 samples were used. For the whole, crushed and milled grains and seeds, according to the type of the sample, analysis of water, crude protein, crude fiber, crude fat and starch were made. The content of crude protein was verified by the chemical laboratory. NIR measurements showed discrepancies in the case of evaluation of individual substances for the whole, crushed and milled grains or seeds, although the same material was used and the measured values should be similar. We have detected for example crude protein content in Apache (Litava) wheat sample by NIRS analysis 129,3 +- 1,78 g.kg-1 for the whole grains, 116,5 +- 0,72 g.kg-1 for the crushed grains and 100,9 +- 2,71 g.kg-1 for the milled grains. The chemical analysis for the same sample showed the value of 120,8 g.kg-1. According to the literature, the crude protein content in wheat should be between 118 and 132,1 g.kg-1. When evaluating the characteristics of the whole, crushed and milled samples crude protein content reached 135,6 +- 8,78 g.kg-1 for the whole, 132,3 +- 9,97 g.kg-1 for the crushed and 130,5 +- 11,55 g.kg-1 for the milled samples. Given that the crude protein measurement results were in accordance with the chemical analyses and the tabular values, it is apparent that the NIR analyzer is working properly. The results of this thesis, however, bring the presumption that the device setting is now not suitable for multiple analyses of different materials.

Vývoj produkce a struktury podniků v komoditní vertikále řepky v ČR
Vacková-Veselá, Lenka
This diploma thesis defines the evolution and changes of canola commodity chain in Czech Republic focusing on primary production and processing stage. Through literature review, based on the theoretical and methodological foundations of agribusiness, canola commodity chain, its determinants, and biological charac-teristics of the commodity are defined. Through analysis of secondary data is captured supply formation and evolution of oilseed rape production in the Czech Republic. Also there are identified changes in the structure of agricultural holdings in given commodity vertical.

Crop production in the world with a focus on cereals and oilseeds
Sárazová, Klára ; Vošta, Milan (advisor) ; Kašpar, Václav (referee)
The aim of this master thesis is to analyse the current trends in production , consumption and trade in cereals and oilseeds. Furthermore, the work seeks to highlight the ever growing importance of these two groups of crop production. It also addresses the issue of declining growth in global agricultural production in relation to the growing population and the factors that affect the price of agricultural commodities. The entire work is conceived in three main chapters. The first provides a particular theoretical framework and includes definitions, localisation factors and many other basic data. The second chapter focuses on crop production in the world and its trends, paying particular attention to the group of cereals and oilseeds. Finally, the last chapter analyzes the world trade in cereals and oilseeds. It also examines the factors affecting prices of agricultural commodities and concludes prediction of the future development of the cereals and oilseeds sectors.

Sociálně ekologické aspekty pěstování palmy olejné a dovozu palmového oleje do České republiky
Štěpánová, Monika
The bachelor thesis describes the family Arecaceae and genus Elaeis. The following chapters deal with the history of the distribution of palm oil, suitable climatic conditions for growing the tree, obtaining of fruits and their processing. Part of the work is devoted to the world's largest producers, exporters and importers of palm oil. Graphs and tables complement the statistic. Next section states the import of palm oil into the Czech Republic and the largest importers into the European reselling countries are characterized. I follow with these importers in the last part, where I describe the environmental and social impacts of oil palm cultivation on the environments and inhabitants of these states.

Oil-crops growing in the Czech Republic 1990-2012
HÁVOVÁ, Šárka
The bachelor thesis is the cultivation of oilseeds in 1990 - 2012. The work deals with the biological characteristics of selected species of oil, the quality of oil and its usage. In the other chapters describes the development of crop varieties, cultivation areas, yields and changes in agricultural technology from 1990 to 2012. The oil is described in the work of five major crop producing in the Czech Republic are oilseed rape, white mustard, sunflower, poppy and flax.
