This thesis deals with the gluten-free diet and its possible enrichment. It is divided into two parts. The first part includes chapters such as history of gluten-free diet, basics of a gluten free diet, the first step in the introduction of a gluten-free diet, gluten-free food labeling legislation and the use of alcohol on a gluten-free diet. The practical part is focused on enriching the diet celiac patients. I focused on the preparation of bakery products for celiac, I have designed and practically tested recipes gluten-free pizza, buckwheat corpus, gluten-free sourdough seedcake and gluten-free cake with homemade pudding and caramel. The finished gluten-free products were submitted after baking consumers who rated their sensory quality. If necessary, an adjustment was made to the recipe and re-perform sensory evaluation. The prepared products were evaluated positively. Selected coeliacs decided suggested products to include in their diet.

The diploma work deals with the analysis of the logistic chain of the selected company, which is a producer of frozen potato specialities. The diploma work deals with analysis system control quality, analysis stocking deep frozen products, distribution products end standard of provided service.

The primary aim of my diploma thesis is the definition of the activity of the State Veterinary Administration of the Czech Republic (SVA). It is a public administration body under the Ministry of Agriculture of the Czech Republic and it was established according to the Veterinary Act No. 166/1999 (the full statutory is Act. No. 286/2003). The main tasks of SVA are: protection of consumers from products of animal origin likely to be harmful to human health; monitoring of animal health situation and maintaining it favourable; veterinary protection of the state territory of the Czech Republic; animal welfare and animal protection. In the first part, the detailed activities on food quality control are analysed. In the next part I targeted the remedial measure, which can be used by inspectors and then discretionary remedies, by which operator can defend against. Finally I have described how heavy the penalties are not only in the whole Czech Republic, but also in particular regions.

This master thesis deals with the issue of sustainable diets and the potential of the promotion of sustainable principles in public food procurement. The theme is introduced in broader context of environment, public health, historical development, international influences, significant theoretical approaches and fundamental factors affecting current state of diets and nutrition. The aim of the thesis is to specify universal principles of sustainable diets, which were derived from critical review of scientific literature and other relevant texts. The character of this thesis is dominantly theoretical. Discussing the potential of applying the principles of sustainability from the side of public institutions is the main theme of the second part of the study. The research question is related to the possibilities of local organic food consumption in school food system in Czechia. Main results show problematic combination of the requirements for both organic and local food in the context of the volume of school food demand and relatively small local organic production. In general terms the contribution of this thesis is the introduction of the research issues of geography of food and presenting the possibilities of further research. key words: sustainable diets, nutrition transition, food, organic...

Local food is a current topic within the Czech food market. The Thesis is focused on the food quality mark "Regionalni potravina" as an instrument for local production promotion. Aim of the thesis is to verify whether labeling local food with the quality mark "Regionalni potravina" contributes to the local food production. An analysis has been performed, that focuses on The Ministry of Agriculture of the Czech Republic's project "Regionalni potravina" in The Usti Region. The analysis contributes to the current local food issue from the perspective of consumers and producers. A questionnaire survey among The Usti Region's consumers and local food producers, that were awarded the quality mark, has been performed. Half of the respondents claim to consume local food, they appreciate its quality and clear origin. The food quality mark "Regionalni potravina" has appealed to the consumers, thus they are motivated to buy local products. That leads to promotion of local food production. The survey was able to prove that the food quality mark "Regionalni potravina" truly leads to promotion of local food production. Considering these conclusions and consumers' attitude towards local food, it would be worth considering to promote a wider range of local food producers who meet the quality and local origin requirements.

This work deals with customer loyalty and loyalty programmes in areas of buying chemist goods, clothing, footwear and groceries. The main objective of this work is to compare the approach of English and Czech customers to loyalty programmes in these areas. The intention of the analysis is to discover whether the approach to loyalty programmes in these two countries varies and what are the major differences. Does using a loyalty programme really affect customer loyalty? Who are more loyal, Czech or English customers? The aim is also to find out how customers use their loyalty programs, what kind of rewards are the most attractive for them and what personal information are they willing to provide when they sign up for loyalty programmes. The analysis also aims to pose these same questions to multi-brand partnership programmes and also mobile applications. This work can therefore benefit companies operating in both Czech and English markets to adapt their loyalty programs to be most effective.

This diploma thesis is worked out as a proposal for a business plan for establishing a small company in the area of agriculture primary production. The worked out business plan is based on analysis of the environment for the new company and from primary research. Theoretical part of the thesis deals with basic concepts which are related to business activities in the current condition. The proposition part consists of a proposal itself for the new business plan and the perspectives of implementing the plan and also risk that come with it.

Acrylamide is an undesirable carcinogenic component of thermally processed foods being formed from reducing saccharides and asparagine. In this work, the effect of ammonium and sodium raising agents themselves or in their combination with L-asparaginase enzyme catalyzing the conversion of asparagine into aspartic acid resulting in the reduction of acrylamide in gingerbreads was studied. Also, the influence of selected inorganic salts on the content of acrylamide in a model matrix simulating a composition of cereal products was observed. Simultaneously, the impact of these salts on activity of L-asparaginase was examined to find optimal conditions for its application in cereal technology. Based on experiments it was found, that addition of L-asparaginase reduces acrylamide content by 40 % while inorganic salts addition decreases acrylamide content in the range of 30 - 99 % when the most effective compounds were NH4Cl and CaCl2.

Acrylamide (AA) is a probable human carcinogen and undesirable contaminant which is produced by the reaction of reducing sugars with asparagine in plant foods during their thermal treatment above 120 °C. AA is most often determined by GC-MS and LC-MS/MS in isolates from the matrix in a wide range of foods. According to our observations, AA intake from food is higher among young people (from 1.8 to 3.8 µg/kg bw/day), which is consistent with the estimations of JECFA FAO/WHO from the year 2006. Considering the health risk, it is recommended to reduce AA formation in food during its processing, in particular exploiting the available experience. The aim of this thesis was to extend the knowledge of the possibility of AA elimination in selected types of thermally processed foods. The study was focused on cereal foods that contribute significantly to AA exposure, especially bread and sweet biscuits. The whole AA content in the bread is in the crust, which represents 5-15% of the bread. Crust of home-made bread contains approximately 30-75 µg/kg, however the marketed bread contains 2 to 10 times more of AA. This is due to the composition of bread mix, preparation conditions and baking. For maintaining the quality of home-made bread during the dry mixture shelf-life, optimization of bread mixtures was designed by increasing of yeast content, which proved positive effect on the reduction of AA content at sufficiently high activity of the yeast. Monitoring of AA content in assortment of sweet bakery products showed higher levels of AA in diabetic biscuits containing fructose instead of sucrose. Three of them even exceeded the reference value (500 µg/kg) more than 1.5 times for commodity "cookies". Elimination of AA by applications of the enzyme asparaginase has been designed for minimal interference in technology of their production. The concentration of the enzyme and the appropriate method of its use in industrial environment have been tested previously in model systems. In optimized conditions of the enzyme application, AA content in diabetic biscuits was reduced by more than 40% without affecting the organoleptic properties of the final product. Effect of the antioxidants on AA formation was also part of the study. AA content in gingerbread was reduced efficiently by the use of fennel, anise, cloves, vanilla and white pepper (by about 9-21%). Conversely, coriander and cinnamon significantly increased its content (by 18-54%). Since correlations between the DPPH• radical quenching activity of the spice extracts and AA content was not observed, the final content of AA was probably influenced by the chemical composition of spices and reactivity of the individual components in the matrix. Investigated methods appear to be suitable ways of elimination AA in some foods; however their specific use must be optimized with regard to the composition of the food, processing and the technology used. Estimated impact of application of the above-mentioned methods to the overall elimination of AA exposure showed that its intake in high school students from the Czech and Slovak Republic can be reduced on average by 10%. This decrease is a success to reduce the possible risk of cancer disease by eating foods with a high AA content. It is also important piece of information for food producers for further development of relevant methods for AA elimination which would help to reduce the AA intake from foods even more.

The main theme of this work is the local food and local multiplier, which is an indicator of sustainable development. The aim of this indicator and as well as this work is to determine how much local money stay in this area. By way of local food is outlined the impact of the economic localization on social, environmental and also economic aspects of sustainability. The theoretical part covers topics such as the Anthropocene, globalization, economic growth, localization and promotion of local food in the Czech Republic. Further is described the local multiplier and its use. The research includes a brief assessment of the situation of sales of local food in Pilsen and in particular, the calculations of local multiplier of farm shop in Pilsen. Furthermore this method and the results are evaluated. The thesis is combination of social and cultural ecology and Keynesianism with emphasis on the concept of the multiplier. Firstly, the aim is to calculate the value of the local multiplier and also evaluate the use of this tool. Since assuming positive influence of the farm shop on the local economy, the result of the indicator could be another argument for strengthening efforts in promoting local food and localization.
