The Diploma thesis deals with influence of dietary fibre on the gluten-free biscuit recipe. A recipe for ten samples was proposed, the basis of which was buchwheat flour and cornflour in a 1 : 1 ratio with the addition of wheat fiber, bamboo fiber, and psyllium at 3 %, 6 %, and 9 %. Subsequently, the effect of fiber on the sensory and physical quality of biscuits was assessed. After the baking experiment, we found that the most attractive was the biscuit without the fiber addition, followed by the biscuit with the addition of 3 % psyllium. Biscuits with the addition of 9 % bamboo fiber were the least tasty. The most fragile was the sample with the addition of 6 % psyllium. During the sensory evaluation, all observed attributes were assessed separately and then each of these parameters compararted to overall evaluation. The most important monitored parameter was the taste, which had the greatest influence on the overall impression of the product.

The aim of the thesis entitled "Pasta with addition of fiber and their benefits to human nutrition" was to design a suitable recipe for the production of gluten-free pasta. In the laboratory at the Institute of Food Technology at Mendel University was produced a 30 samples of gluten-free pasta altogether and they were made from gluten-free ingredients - rice and corn flour. Various types of fibers with different length have been added to increase the nutritional value of products. As a substitute for gluten was used hydroxypropylmethylcellulose. There were measured hardness of all pasta samples from physico-chemical methods. Further tests of cooking and sensory evaluation of raw and cooked pasta were performed. As sensory the best evaluated samples were prepared from rice flour containing 4% (sample no. 21) and 8% (sample no. 22) wheat fiber type WF 600 and without the addition of any fiber (sample no. 30).

The master thesis Possibilities of production of beer, bread and pasta products for celiacs deals with using naturally gluten free raw materials for the production of gluten-free bread, pasta and beer destined for the needs of celiac patients. The thesis describes the problems of celiac disease, its symptoms and treatment methods, which among other things based on a strict gluten-free foods eaten. The practical part is designed and tested recipe for the Christmas cakes production of gluten-free mixture Jizerka, with the addition of 0%; 3%; 5% and 7% of wheat fiber, then were prepared gluten-free pasta using 6% bamboo or pea fiber were produced, and gluten-free beer using malt produced from maize varieties equine tooth. Gluten-free products have subsequently been sensory tested and the results evaluated by the availa-ble statistical methods.

The main aim of this thesis is to analyse restaurants in Prague which offer special dishes for people who suffer from celiac disease. Theoretical part consists of definition and history of celiac disease, symptoms of celiac disease etc. One of the aims of the practical part is to create a free city map with marked restaurants suitable for people who suffer from celiac disease. The author conducted a survey among tourists whether they would appreciate this kind of map.

This thesis is focused on catering for pupils with celiac disease in school canteens. The first part, the theoretical one, deals with the disease itself; it gives basic information about the disease, its history, main symptoms, anatomy of healthy digestive system, and the most common health problems occurring when suffering from celiac disease. At the end of the theoretical part diagnosis of the disease is described as well as suitable and unsuitable diet food for celiac and food legislation. The practical part is a survey focused on catering for pupils with celiac disease at selected elementary schools. The survey was conducted in two regions in Valašské Meziříčí and in Prague. In the final part of my thesis special gluten-free menus for schools are suggested. The pedagogical outcome of my thesis is a lecture on celiac disease which can be held at elementary school s to help pupils find out basic information about this disease.

Celiac disease is an autoimmune disease which occurs in susceptible individuals after ingestion of food containing gluten. Gluten and its monomeric fraction gliadin induce inflammatory damage of the small intestine by activating the immune cells that react strongly to gluten peptides. Gluten peptides have the ability to activate cells of adaptive as well as innate immune system. This work is focused on the production of interleukin (IL)-1 in antigen presenting cells stimulated with peptic gliadin digest. We found that monocytes and peripheral blood mononuclear cells (PBMC) isolated from blood of celiac patients secrete significantly more IL-1α and IL-1β than cells of healthy donors after stimulation with gliadin digest. The gliadin-induced IL-1β expression is controlled by a signaling cascade that includes MAPK kinase family molecules and transcription factor NF-κB. Moreover, we found that the adaptor proteins MyD88 and TRIF as well as Toll-like receptor (TLR) 2 and 4 play a role in the signaling cascade underlying gliadin-induced IL-1β expression by using murine bone marrow derived dendritic cells (BMDC). The precursor form of IL-1β in gliadin- stimulated PBMC and murine BMDC is maturated by caspase-1. In celiac PBMC the gliadin- induced maturation and secretion of IL-1β depends on the potassium...

The aim of the thesis was to suggest mixtures for making of gluten-free bread with the addition fiber. Within the baker's experiment 18 recipes were suggested. Rolls were baked with two types of hydroxypropylmethylcellulose (HPMC) containing wheat fiber WF 200 and WF 600 and oat fiber HF 600 in an amount of 2 %, 5 % and 7 %. Quality assessment rolls included sensory evaluation, hardness measurements using TIRA TEST, measurement volume rolls, baking and calculate the loss ratio numbers. The results of the evaluation were statistically and graphically presented. The most suitable recipe was evaluated the recipe with a sample of 2 % wheat fibers with a fiber length of 600 micron using HPMC type E and sample was 7 % wheat fibers having a fiber length of 200 micron using HPMC type K. These samples were demonstrably evaluated as the best sensory evaluation (p < 0,05).

This diploma thesis analyses the consumer behaviour of people in the age 18-40 years on the market with gluten free food. Using a questionnaire survey, eye tracking research and interviews were identified factors which influence consumer buying decision process. The thesis focused both on the sales of gluten free foods in stores as well as sales through online stores. There were some significant differences between types of consumers, according to which it was possible to create personas. The research results were the basis for creating general marketing advices for subjects on this market.
