Využití netradičních asijských zeleninových druhů
Nollová, Kateřina
The aim of this work was to select and describe the less known species of Asian vegetables. 21 kinds was characterized. There was stated the origin, description, method of cultivation, utilization as well as their nutritional value to them. It was made a survey which evaluates the availability of the unusual Asian vegetables in different markets. From the described vegetables were selected vegetables suitable for growing in our climate conditions. They were selected according to the content of vitamins and minerals. As a perspective seems to be bazel, borage, chinese broccoli, komatsuna and perilla.

The lipid quality of our economically significant fish species
KREJSA, Jakub
The level of fish consumption in the Czech Republic is very low. One of the possible factors influencing this situation is low awareness of the customer or consumer. The thesis "The Lipid Quality of our economically significant fish species" works with the list of nineteen economically most significant fish species not only including fish from the semi-intensive and intensive breeding, but also such species that are interesting for the consumption from the sport fishing point of view. The samples taken from particular fish were primarily used for the analysis of the fat content and fatty acid composition. The analysis established very interesting results in this field and created basis for further analysis for establishing atherogenic and thrombogenic index or for formation of nutritive values mentioned as "Big 7" (fat content and the ratio of fatty acid out of it, sacharide content and the sugar ratio in it, protein content, ash content and energy value) by particular fish species according to the regulation ES 1169/2011. The results of this work confirmed that the fat content and its composition are highly influenced by the type of ingested nourishment. The fish bred in semi-intensive way with the highest fat content are Common carp (7,62 ? 2,9 %) and Silver carp (6,87 ? 1,37 %). On the contrary the predatory fish evinced the fat content usually within 1%. The fish from extensive breeding or the types caught in sport fishing are in the fat con-tent more balanced. The fattest fish in this group is Silver Bream (5,52 ? 0,44 %) and the lowest content evinced Goldfish (1,14 ? 0,38 %). Also the species living in the aquaculture and living in the free waters as well were compared (Common carp, Rainbow trout, Peled, Tench, Wels catfish). The fatty acid composition significantly depends on the fat content. The predatory fish contain 195 - 219 mg×100 g-1, the most (p0,05) was found by the peled from the extensive breed (1048 mg×100 g-1 EPA + DHA). The participation of SFA by the most of the fish was under 30%, the content of MUFA was the highest by the Common carp (52,71 ? 7,75 %), the lowest by the European perch (18,83 ? 1,12 %). Pike, Zander and European perch contain relatively the most of PUFA, this is over 50%. All the fish species (Nile tilapia excluded) show in this study the values of atherogenic index below 0,5 and thrombogenic index below 0,4. The total energetic value was counted from the results of nutritional values presented in the "Big 7" list. The higher energetic value is directly proportional to the increasing fat content. The fish species included in this thesis show the total energetic value in the range of 500 - 900 kJ×100 g-1. The results of this study bring complete, laboratory proven information about the nutrition composition of our fish. This data can be appli-cable not only to increase the knowledge of the customers but mainly to be used by breeders and manufacturers of fish as an implement of fulfilling the duty of stating the nutrition facts on their products according to ES 1169/2011 on the providing infor-mation about the eatables to the consumers.

Cereal products and their nutritional value
NOVOTNÁ, Jitka
The work deals with the exploration of public awareness regarding the basic knowledgeand consumption of cereal. The theoretical part describes the composition of cereals and their utilization for human consumption. It also deals with the nutritional value of cereals and health aspects of eating cereal. Among other things, the important parts of this work include the labeling of productsmade from cereals, important for market orientation and cereals in the prevention of civilization diseases. This work was done a survey of public awareness regarding the basic knowledge and their cereal consumption. The key idea is to determine what is public awareness and contribute to its increase. Questionnaire method was found that the public is informovaost for people with regularmotion activities higher than those without physical activity, women consume more cereals than men and that public awareness and consumption ofcereals does not increase with age. The conclusions of the work was created and educational leaflet, which summarizedrelevant information regarding their consumption and cereals.
