Růžičková, Magdalena ; Kubalová, Michaela (referee) ; Bendová, Agáta (advisor)
This bachelor thesis focuses on developing gluten-free cereal products for special nutrition. The main focus is on increasing the concentration of phenolic compounds and antioxidants in cereals by adding fruit and vegetable components. The theoretical part includes findings from professional literature on cereals, gluten-free cereals and their chemical composition. A chapter devoted to celiac disease and gluten-free diet was also included. Furthermore, the theoretical part focuses on possible methods of enrichment and also on selected fruits and vegetables used in the experimental part. In the experimental part, five samples of gluten-free cereals were analysed, namely black, red, brown and white rice and corn. The concentration of flavonoids, polyphenols, antioxidants, carbohydrates, proteins, -carotenes, anthocyanins, gluten, -glucans, fatty acids and lipophilic vitamins was determined in the cereal samples. Selected samples were also tested for antimicrobial activity. The black rice sample showed the best results in the majority of the measurements. Selected samples of eight types of fruit (cranberry, raspberry, strawberry, blueberry, blackcurrant, mango, banana, kiwi) and four types of vegetables (broccoli, carrot, green pea, beetroot) were also analysed. The concentration of flavonoids, polyphenols, antioxidants, carotenes, anthocyanins, ascorbic acid and lipophilic vitamins was determined in these samples. Antimicrobial tests were performed on selected fruit and vegetable samples Among the fruit samples, the best results in the majority of measurements were in blueberry and blackcurrant samples. Among the vegetable samples, the best results were obtained from the beetroot sample. From the best cereal, fruit and vegetable samples were created porridges as a final product. In these samples, the concentration of polyphenols and antioxidants was determined. The highest concentration of both compounds was found in the porridge with black rice and blueberry.

Plant-based alternatives to dairy and meat products and their nutritional value
Faltýnová, Kristýna ; Dostálová, Jana (advisor) ; Chrpová, Diana (referee)
This bachelor thesis focuses on exploring plant-based alternatives to milk, dairy, meat and meat products. The thesis is divided into two parts, theoretical and practical. The theoretical section examines the nutrients found in milk and meat, ingredients used in plant-based alternatives to dairy and meat products, the nutrients they contain and their impact on human health. In the next chapter I summarize the legislation concerning meat and milk, this is followed by a chapter examining ultra-processed foods (which include plant-based alternatives to meat and dairy), and another chapter focused on vegetarianism - characterizing its different types, explaining its benefits and risks and describing its history. The primary objective of this thesis was to investigate public awareness of plant-based alternatives to milk, dairy and meat products, with a secondary goal of comparing the views of vegetarians and vegans to non-vegetarians. The first part of the practical section is an evaluation of an anonymous non-standardized questionnaire. This survey was used to determine the respondents' awareness of plant-based products and their nutritional value. A total of 349 people participated, including 222 non-vegetarians, 88 vegans, and 39 vegetarians (lacto-ovo vegetarians) from various age groups and...
