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.

The use of caffeine among pupils at second grade of elementary school in Vodnany.
ŠMIDMAJEROVÁ, Edita
This bachelor thesis deals with the consumption of caffeinated beverages by pupils of a secondary school in Vodňany (Czech Republic). Nowadays, the overconsumption of beverages containing caffeine is becoming a big problem among pupils. I chose this topic to find out how many pupils of a regular secondary school drink beverages containing caffeine. This work consists of both a practical as well as a theoretical part. The theoretical part consists of three main chapters. The first part describes the subject, caffeine, the effects caffeine has on the human body as well as caffeine addiction. In the second chapter I investigate products containing caffeine, their ingredients and effects on the human body. The third chapter focuses on the consumption of caffeinated beverages by teenagers. In this chapter I describe the term teenager, their eating habits and explore whether these are appropriate or not. Furthermore, I present studies focused on caffeine consumption based on the age range of the consumers, from toddlers up to the age of thirteen. In the practical part I set two goals. The first is to determine how many pupils of the investigated secondary school drink caffeinated beverages. My second goal is to determine at which occasions they drink these drinks. Furthermore, I establish two research questions and two hypotheses. My first hypothesis assumes that female pupils of the secondary school in question drink in general more caffeinated beverages than male pupils. However, based on the evaluation of the obtained data I found out, that the female pupils do not consume more caffenated drinks than male pupils. My second hypothesis assumes that pupils drink caffeinated beverages more often during the week than on the weekend. But even this hypothesis was not confirmed, as the survey shows that pupils do not consume caffenited drinks more often on weekdays than weekend. Both hypotheses were statistically evaluated using the Excel chi-square test. The working method is described in the practical part. The practical part was carried out using quantitative research methods, i.e. a survey. The survey was anonymous and the questionnaire was for both genders identical. It consisted of 16 questions that focused on the consumption of beverages containing caffeine. The survey consisted of closed, half-closed as well as opened questions. The data were collected at the mentioned secondary school in Vodňany. The questionnaire was given to pupils of the 7th, 8th and 9th grade, aged between 12 and 15 years. In total, 80 questionnaires were distributed among the pupils; the return rate was 100%, as they were distributed duringclass while a teacher was present. The analysis of the questionnaires gave the following results: the most favourite caffeinated beverage among students is coke. The biggest proportion of pupils drinks as much as 0.5 liters per day of coke. The most popular brands of caffeinated beverages are Coca-Cola, Kofola, Monster and Red Bull. Pupils mostlyconsume caffeinated drinks on the weekend with friends or family. My work could be used as a source of information for the general public, or as a basis for further studies of students who are dealing with the issue of caffeine.
