Pěstování léčivých rostlin z čeledi Asteraceae
Synková, Lucie
This bachelor thesis is focused on the topic Growing medical plants from Asteraceae family. Medical plants have been used in ancient times. Recently, their popularity is increasing. Asteraceae is one of the largest family of higher plants. Plants from this family are used not only in pharmacy, but also in cosmetic industry and food industry or in the process of liqueur making. In this thesis is described characterization of Asteraceae family, as well as characterization of medical, aromatic and spice crops. Furthermore, various active ingredients contained in medical plants and their effect on the human organism and general rules for growing medical plants are described. Next chapter describes growing of selected species from Asteraceae family, substances contained in medical plants from this family and posibilities of their utilization. Emphasis was put on growing chamomile (Matricaria chamomilla L.) and marigold (Calendula officinalis L.).

Reologické vlastnosti různě tučných bílých jogurtů
Synková, Lucie
This diploma thesis Rheological properties of plain yoghurts with various fat content is aimed in its theoretical part on the basic summary of fermented milk products. It is focused mainly on yoghurts, especially plain yoghurts. The manufacture, composition, nutritional and health benefits, storage and shelf-life of yogurts is described. In the next chapter are described rheological properties of foods. The aim of the practical part is to assess rheological properties of plain yoghurt with various fat content. All samples are commonly available in the Czech shops. The range of fat content was 0,1–10,2 g/100 g. The dependency of shear stress on shear rate was studied as well as the dependency of apparent viscosity on shear rate (1,02–68 s-1). The rheological properties were fitted to Ostwald-de Waele model (the Power law). It was assessed that yoghurt is a Non-Newtonian fluid with shear thinning behaviour. Determination coefficients achieved high values (0,8748–0,9905). Time dependency and effect of various temperature (4 °C, 12 °C and 22 °C) on apparent viscosity was assessed. pH, titrable acidity, fat content and dry matter content were observed for all samples.
