Analysis of drinking mode of university students Czech republic
VESELKOVÁ, Barbora
The diploma thesis deals with analysis of the drinking regime of students of the Technical and Economic University (VŠTE) in České Budějovice. The theoretical part contains informations of the drinking regime in general, the suitability of widely discussed and used beverages. At the end of the theoretical part are the best recommendations, which todays literature, studies and other sources can offer. I have used questionnaire survey for the quantitative research. A total of 1515 students of the Technical and Economic University in České Budějovice have attented this questionnaire survey. Obtained answers are then evulated and compared with given hypotheses in the practical part.

Development of massmedial communication of energy drinks between 2010 and 2015 with a focus on television advertising
Mošnová, Kamila ; Novák, Michal (advisor) ; Přibil, Jiří (referee)
The bachelor thesis defines mass media and the forms it can acquire. It shows their importance in marketing communication and lays more emphasis on advertising and television. This thesis is specialized on monitoring of marketing communication of energy drinks brands while the theoretical part describes its most frequently used forms. The practical part is focused on the television commercials in the time period between years 2010 and 2015. It evaluates the situation of television commercials promoting energy drinks on the Czech market in individual years of given period. It also monitors their development in time, and based on the discovered conclusions appraises the importance of television advertising nowadays.

Development of a new type of energy drinks containing natural active components
Vysoká, Marie ; Němcová, Andrea (referee) ; Skoumalová, Petra (advisor)
The aim of this thesis is the development and preparation of a new energy drink. The theoretical part of the thesis focuses on the comparison of the drinks available in market, the presentation of the main active ingredients and the proposal of enriching the new energy drink. It also describes the possibility of using an encapsulation and the method used to determine specific compound in energy drink or encapsulated particles. In the experimental part of the work, at the beginning, the main content of energy drinks were characterized, for instance caffeine, sugar, polyphenol and vitamin C. Subsequently the energy drink based on selected types of loose teas that were enriched with the encapsulated extract of acai, acerola, maca, goji and ginseng was designed. All extracts contained large amounts of polyphenols and antioxidants. In addition, acerola extracts contained very high amounts of vitamin C. Two types of particles, alginate particles and liposomes were prepared for encapsulation. For all particles, encapsulation efficiency, size, stability, and antioxidant activity were determined. Long-term stability was then monitored within three months. The particles were also exposed to artificial gastric, pancreatic and bile juice. All tested particles showed very good encapsulation efficiency. In terms of long-term storage stability in an aqueous environment. Particularly liposome particles, which also showed high stability by zeta potential measurement, were suitable. On the contrary, in case of alginate particles, when stored in an aqueous medium, the release of active substances occurred. Finally, an energy drink was created and subjected to sensory analysis. The best energy drink was based on black or green tea with alginate particles acai, goji and ginseng.

Electrophoretic separations of saccharides in short capillary.
Vochyánová, Blanka ; Opekar, František (advisor) ; Jelínek, Ivan (referee)
A new laboratory system has been developed for rapid electrophoretic separations and determinations of inorganic and organic ions. The instrument employs short fused silica capillary in combination with contactless conductivity detection. The basic functions of the apparatus have been tested using mixture of inorganic ions. It has further been applied to separations of neutral mono- and disaccharides. The model mixture contains five saccharides (sucrose, lactose, glucose, fructose and ribose). The technique developed has been used to determine sucrose, glucose and fructose in high-energy drinks.

Characterization of beverages and food supplements containig caffeine
Patočková, Klára ; Pekař, Miloslav (referee) ; Márová, Ivana (advisor)
This master thesis is focused on characterization of some energy drinks and formulation of their modified composition. The theoretical part was focused on summary of energy drinks and some of their natural components - guarana, goji as well as on techniques of encapsulation. In the experimental part concentrations of caffeine, vitamin C, polyphenols and carbohydrates in commercially purchased drinks was evaluated. Subsequently, three kinds of particles (particles with caffeine, particles with guarana and particles with guarana and goji) by 6 different techniques were prepared. The efficiency of encapsulation was determined by HPLC/UV-VIS (caffeine, vitamin C) and by spectrophotometry (phenolics). Stability of the particles was followed in real food and in a model physiological environment of artificial digestive juices. Size of prepared particles was determined by dynamic light scattering. In this work it was found that particles with best activity and stability were obtained by encapsulator. For manual particles the best results were found in the liposome particles. Liposomes exhibited the smallest particle size, the highest efficiency encapsulation, excellent stability in real food and juices and the best value of zeta potential.

The Role of Energy and Stimulating Drinks in the Drinking Regimen of Adolescents
ŘÍHA, Jakub
The thesis deals with the consumption of energy and stimulative drinks by adolescents in the Czech Republic. This current topic is treated in the theoretical part of the thesis, in its two sections. In the first section, the important terms, such as ?adolescence? or ?digesting drinks?, are explained. The second theoretical section deals with the daily fluid intake and describes energy and stimulative drinks, their composition and their impact on human body. There is also information about the use of these drinks in combination with alcohol. The practical part of the thesis contains analysis of the consumption of energy and stimulative drinks by adolescents from 15 to 26 years of age. More than 1,200 respondents took part in the electronic research. To compare the results, there are two age groups: 15-20 years of age and 21-26 years of age. The results of the research confirm that energy drinks are consumed at the usual rate, while stimulative drinks are included in the daily fluid income of Czech adolescents very often. The main reason for consumption of these drinks is to eliminate the feeling of tiredness.

Analýza strategie Red Bullu a její asociace s extrémními sporty
Janek, Alicja ; Cook, Gina (advisor) ; Lisa, Aleš (referee)
Sports marketing is divided into three sectors: marketing of a sport, marketing products and services through sports and promotion of a sport to the public. This thesis is mostly referring to marketing through sport, and its analysis of a very unique and innovative organization. Red Bull GmbH is a leader within the dynamic area of energy drinks, a fast-growing area of the beverage sector. The objectives of this thesis are to show how Red Bull develops its marketing strategy and identify the principles and processes involved, to describe the tools and techniques used in their marketing and show how they have been applied. The main goal of this thesis is to explain how effective is the association with extreme sports for Red Bull.
