Tobolková, Blanka ; Vránová, Dana (referee) ; Zemanová, Jana (advisor)
A dietary supplement is a product that contains nutrients (e.g. vitamins, minerals, herbs, amino acids or fatty acids) intended to supplement the diet. The aim of the diploma thesis was to suggest a prescription for preparation of three types of dietary supplements which are used to reduce of climacteric symptoms, their production and determination of energetic (nutrition) value on account of detected content of proteins, fats and saccharides in dietary supplements. A part of the diploma thesis was to suggest suitable wrapping and price of prepared dietary supplements. The three dietary supplements were used for analyses, namely capsules, herb syrup and herb drops. The content of proteins was determined by Kjeldahl´s method, total fats were determined by Soxhlet extraction and saccharides were determined by titration with potassium permanganate (Bertrand´s method). Dietary supplements in form of capsules were particular analysed on content of heavy metals (lead, cadmium and arsenal). In herbal drops was in addition determined alcohol content (ethanol). There was from the measured data found out, dietary supplement in form of capsules was chosen as the product with the lowest energetic (nutrition) value.

Izraelová, Alexandra ; Vespalcová, Milena (referee) ; Souralová Popelková, Miriam (advisor)
The aim of this thesis was to design a recipe for the dietary supplements with adaptogenic effects, production, and subsequent analysis (proteins, lipids, carbohydrates), which led to the determination of the energetic value of preparation. Adaptogenic effects are the domain of plants and fungi, known as adaptogens. Adaptogens act non-specifically to the human body - improve the overall condition of the body, accelerate healing and regenerative processes, slow degenerative processes in the body and thus the aging process. As biogenic active stimulators, they affect not only in the physical but also in mental area. Dietary supplements have been designed in three different forms - capsules, syrup, drops. The analysis was also performed in tablets of Vietnamese origin supplied by supervizor, of which entry to our market is being considered. Protein content was determined by Kjeldahl method, lipids by Soxhlet extraction, saccharides by gravimetric method. Dietary supplements were analyzed for heavy metals (Pb, Cd, Hg), and in herbal drops ethanol content was determined.
