Spotřebitelské chování na trhu s mlékem a jeho rostlinnými alternativami
Zemanová, Eliška
The thesis is focused on the characterization of segment of final consumers of cow's milk and plant-based milk alternatives in the Czech Republic. The aim of the thesis is to analyze the consumer behaviour of people interested in the consumption of the mentioned products. The literature review was followed by a description of the market for milk and plant-based milk alternatives. The research was carried out in the form of a questionnaire survey, in which 383 respondents was originally participated, but 6 respondents were subsequently removed from the research due to incorrect completion of the questionnaire. The established hypotheses were evaluated by the Pearson Chi-Square Test. The research found out that more respondents consume cow's milk than plant-based milk alternatives, that consumers are willing to pay more for higher quality products, and in the area of plant-based milk alternatives, according to a minority of respondents, there is a demand for a larger assortment. In conclusion, recommendations for business entities operating in the market were proposed.

Importance of milk and its plant based alternatives in human nutrition
Schýbalová, Tereza ; Dostálová, Jana (advisor) ; Chrpová, Diana (referee)
Milk is a basic component of food represented in the menus of the vast majority of the population. Consumption affects enough essential proteins, fatty acids and minerals in diet. Even thought milk is an integral part diet, because of modernization of recent years, it has been replaced by plant-based drinks - almond, coconut, oat, soy. The work includes a detailed analysis of both food groups and their subsequent comparison within the framework of the effect on human health. The theoretical part of the presentation deals with types of animal milk - cow's, sheep's and goat's. All three types of milk will be analyzed, both from the point of view of chemical composition of proteins, carbohydrates, fats, vitamins and minerals and from the point of view of their positive and negative effects on the human organism. After that, the theoretical part deals with second group, as with plant based drinks. I discuss almond, coconut, oat and soy drinks, their chemical composition and positive or negative effects on human health. In the conclusion, both food groups are compared and ambiguities regarding the importance in the diet are clarified. The practical part is divided into two parts. The aim of the first part of the practical part was to find out, using an online questionnaire, whether the general public...

Nutritional and sensory value of plant-based beverages as alternatives to milk
Němcová, Tereza ; Doležal, Marek (advisor) ; Ilko, Vojtěch (referee)
The presented bachelor thesis deals with the issue of increasingly popular plant-based alternatives to cow's milk. The practical part focuses on the nutritional and sensory evaluation of beverages derived from oat grain. The theoretical part describes the different plant raw materials from which they are produced. It compares them from a nutritional point of view, describes the possible occurrence of anti-nutritional substances and their effects on the human organism. Subsequently, the thesis compares plant drinks with the parameters of cow's milk. In the practical part, 10 samples of oat drinks were analysed using the following methods: gravimetry for the determination of dry matter content, liquid-liquid extraction (LLE) for the determination of fat and Kjeldahl method for the determination of crude protein content. In order to obtain the necessary data, the ash content after the samples were ashed in a muffle furnace was determined gravimetrically and the carbohydrates were determined by calculation. The fatty acid content was determined by gas chromatography with flame ionization detector (GC/FID). Finally, a sensory profile evaluation method was performed. The results were then compared and discussed with previously published data. The analysed oat drinks contained approximately the same...

Milk and its alternatives
Pastorková, Eva ; Hubáček, Jaroslav (advisor) ; Suchánek, Pavel (referee)
The thesis focused on milk and its alternatives, i.e. plant-based drinks. The theoretical part summarized the nutritional value of milk and its consumption in the world and the Czech Republic. As a source of fats, proteins, minerals, and vitamins, milk is of nutritional value. Furthermore, the importance of milk in human nutrition for different age groups was discussed. Related dietary recommendations and reasons limiting milk consumption were introduced. This included health reasons such as lactose intolerance, cow milk protein allergy or the rarely occurring galactosemia, as well as ethical or environmental reasons. Last but not least, alternatives to milk, i.e. plant-based drinks, were presented. These drinks are based on extracts of legumes, cereals, nuts and/or seeds diluted with water and often supplemented with other additives. The practical part aimed to assess the dietary habits of the general public and nutritionally educated people regarding the consumption of milk and plant-based drinks, including their awareness of the importance of this food in human nutrition. Data were collected using a questionnaire survey. In addition, the nutritional values of selected plant-based drinks were also compared with cow's milk. Within the sample studied, milk was observed to be a frequent part of the...

Možnosti výroby vybraných nápojů se zvýšeným obsahem vlákniny
Ondrůšková, Gabriela
Diploma thesis is bearing title Options of production of selected beverages with increased fiber content. Firstly the thesis is processing characteristics of dietary fiber, it also describes individual components of fiber, its effects on human health and its potential utilization in the food industry all is included in the literary research section. Secondly the thesis continues with the experimental part which comprises possibilities of production of fermented and non-fermented beverages with higher content of fiber. Single samples of beverages were analyzed and the total and insoluble fiber content was determined followed up with calculating the soluble fiber content. Then determination of nutrients was supplemented by determinating the sugar using HPLC method. Finally, the produced beverages were subjected to sensory analysis. According to sensor analysis the overall best-rated beverages were those made of oat caramel malt and oat flakes contrary to beverages made of chia seeds and linseeds, which were evaluated as the worst. Furthermore oat-based beverages contains the highest amount of total fiber in comparison with oat beer and rice beverage in which the lowest content of fiber was determined. Complete overview of results of individual determination of fiber in beverages, nutritional parameters and sensory analyzes including ilustrations are presented in practical part of the thesis.

Nové směry v technologii výroby mražených krémů
Kašparová, Aneta
Diploma thesis deals with new technologies, which could be used in the ice cream manufacture. First three theoretical parts are about casual ingredients and ice cream manufacture process. Last two parts are dedicated to food with beneficial bacteria and how it influences human body. The practical part is devoted to ice cream manufacture from different milk based and plant based ice cream mixes with carob addition as a stabilizer and probiotics bacteria, which were incorporated to the mixes in different times of activations. Sensory evaluation proved, that replacement of milk has positive effect to the ice cream just as the probiotic incorporation, which causes pleasant yoghurt taste. Microbiological analysis proved sufficient content of living bacteria and therefore a benefical impact on human health.
