Stratílková, Veronika ; Váchová, Alena (advisor) ; Kovaříková, Miroslava (referee)
This bachelor thesis discusses legislative requirements for packed food and how it reflects consumers expectation. The theoretical part of the work clarifies general requirements for packed in food Czech Republic based on Regulation of European parliament and council and Czech national laws and decrees. Special attention is paid to requirements for labeling of the meat and cold meat products. The practical part of the thesis which has been realized by using the questionnaire survey method, focus on detection of circumstances which are important for consumers and for their decision making when they buying food. At the same time, it was investigated how the legislation requirements reflect consumer needs for labeling of food. Results of this research are discussed in the debate. It has been found out strong consumer's need to know the origin of the food. This circumstance is very important for consumers especially for meat and cold meat products. Based on the information obtained has been created proposals for improvements, such as introduction of rules how to make this information clearer for consumer. For example, it might be set up mandatory rule to communicate information about origin of food on the front of pack.

PCR detection of genetically modified soybean in food and feed
JOSKOVÁ, Markéta
The aim of this thesis was to summarize in the theoretical part the issue of genetic modifications and their main use. Another task was to describe various methods used for detection of genetically modified plant products and their properties. The practical part is focused on the isolation of DNA from various foods and feeds containing soy. Using the PCR method, samples were tested for the presence of soy DNA, the CaMV promoter, and the Roundup resistance transgene. A total of 42 samples were tested and 5 of them contained transgenic soy.

Food self-provisioning in Russia: case study of Moscow and Saratov
Nenashev, Daniil ; Spilková, Jana (advisor) ; Rypáčková, Pavla (referee)
Food self-provisioning in Russia: case study of Moscow and Saratov Abstract The main goal of this thesis is to study what is the peculiarity of food self-provisioning in Russia. The thesis tries to capture the main features in a self-provisioning topic, focusing on differences between the capital city - Moscow - and the peripheral city - Saratov. In the theoretical part of the thesis, different views on food self-provisioning, especially in Europe, were considered. The research part of this work is based on semi-structured interviews conducted with 20 respondents, 10 from Moscow and 10 from Saratov. The research sought to find out what are the main reasons to grow food by yourself, what motivates people to do it in "Russian" conditions. The results confirmed the hypotheses that the reason to grow food depends on the economic situation in the area of respondent's residence. Also, climate and soil play an important role. Keywords: domestic food production; self-provisioning; Russia
Potravinářské výrobky jako faktor vnímání Evropské unie v České republice
ŽIDOŇ, Zdeněk
Foodstuffs are often discussed in the Czech Republic in relation to the European Union. In the past, European regulations which affected traditional Czech food products caused big controversies. Currently, the most discussed issue in this context is a dual quality of food products placed on the European single market. The introductory part of this thesis deals with a development of this issue in the institutions of the European Union and includes the opinions of Czech Members of the European Parliament. This thesis also analyses related European legislature and proposed solutions regarding dual quality, summaries relevant Czech, Slovak and other foreign comparative tests of products and assesses the most common arguments which the producers use to defend the differences in the composition of their products. The final part of the thesis puts the habits of Czech consumers in contrast with neighbouring countries and, based on available data regarding the opinions about the EU, formulates a theory which answers the question of how dual quality of products influences the perception of the European Union in the Czech Republic.
Optimalisation of a new micromethod of DNA isolation from foods
Surá, Tereza ; Rittich, Bohuslav (referee) ; Španová, Alena (advisor)
The thesis were focused on the optimalization of micromethod for isolation of DNA in quality for polymerase chain reaction (PCR) using magnetic microparticles from plant food products. There were chosen a red beetroot (fresh, frozen, dried and sterilized) for the analysis and food products containing red beetroot. Different approaches of processing of homogenates were compared and optimized. The homogenates were prepared in lysis buffer with cetyltrimethylammonium bromide (CTAB) with different amounts of NaCl with or without addition of organic extraction agents chloroform-octanol and isopropanol. Microisolation of DNA was performed using magnetic particles P(GMA). The concentration of NaCl and polyethylene glycol (PEG) 6000 in separation mixtures was tested. The influence on quantity and purity of isolated DNA was compared and the optimum amounts of NaCl in CTAB buffer and optimal concentration of PEG 6000 in separation mixtures were compared. The optimized separation mixture for the DNA isolation from red beetroot was applied to food products containing red beetroot. Amplifiability of DNA was tested in conventional PCR using specific primers for plant DNA. PCR products of length 700 bp were detected by agarose gel electrophoresis.
