Sensory quality of chosen types of meat products
Javorská, Kateřina ; Sůkalová, Kateřina (referee) ; Vítová, Eva (advisor)
This Bachelor’s thesis deals with the evaluation of sensory quality of meat products. The 5 samples of pork ham of different quality and from different producers were selected for evaluation. The theoretical part focuses on the composition and properties of meat and meat products, and their production technology. The selected methods for sensory evaluation of quality are also mentioned. Ordinal and graphical scales were used for sensory evaluation of samples. The assessors evaluated these basic characteristics of the ham samples - color, appearance in the cut, preparation, consistency, smell, taste, saltiness and tenderness. The results were written down in the prepared questionnaires which were subsequently statistically and graphically evaluated. Sensory analysis was performed by group of students from the Faculty of Chemistry BUT.

Determination of selected chemical parameters of fruits of modern gooseberry varieties
Javorská, Kateřina ; Vítová, Eva (referee) ; Vespalcová, Milena (advisor)
Diploma thesis deals with determination of individual chemical parameters contained in modern varietes of gooseberries (Grossularia uva-crispa). The theoretical part is focused on the botanical characteristics of the plant, a description of selected varietes, chemical composition and food utilization fruits. The second half of the theoretical part is devoted to the characterization of selected nutritional parameters and methods for determination of total anthocyanins, phenolic compounds, vitamin C and antioxidant activity. Total of 17 varietes of gooseberries, which come from growers Vondráček and the Research and Breeding Institute of Pomology Holovousy Ltd. were analyzed in the experimental part. pH differential method was used to determination total monomeric anthocyanins. Total content of polyphenols were determined by using the Folin-Ciocalteu reagent. Next was determined content of vitamin C in all varieties by HPLC and was evaluated the total antioxidant aktivity using radical DPPH. In conclusion, individual varieties of gooseberries were compared by the contents of the determined chemical parameters.
