Kovaříková, Tereza ; Vespalcová, Milena (referee) ; Diviš, Pavel (advisor)
This master thesis deals with the analysis of nutritional properties of paprika condiment with different geographic origin. The theoretical part contains botanical description of red pepper (Capsicum annuum L.), its chemical composition, process of production of paprika and then they are described analytical methods suitable for determination of fundamental nutrional properties. Experimental part is focused on the preparation of samples and their analysis. In total, 11 samples were selected for the experiment, 5 of them had a protected designation of origin. These samples were from Slovakia, Hungary, Bulgary, Romania, Turkey and Spain. The Soxhlet extraction was used for the analysis of the fat content, Kjeldahl method was used to determine gross protein. High-performance liquid chromatography (HPLC) was chosen to determine carbohydrates and capsaicin. Induction-coupled plasma emission spectroscopy (ICP-OES) was used for elemental analysis. The results were compared with each other and with available databases and literature. For comparing and finding certain connections, the principal component analysis (PCA) was selected.
