Perspektivy využití laktoferinu
Pavlík, Patrik
The thesis is focused on summarization of knowledge on lactoferrin, its sources of production, methods of isolation, biochemical properties, structure and resistance to denaturation under different conditions. At the same time, the biological effects of lactoferrin on the human body are specified, mainly focusing on antiviral effects, immune support and athletes performance enhancement. Moreover, the encapsulation methods of Lf and its delivery to the body are described here, where the most effective method of Lf, still remains the oral administration method. The current utilization of Lf in food processing and other fields is discussed. In the experimental part, food matrices suitable for 3D printable edible coating were prepared. By following encapsulation of Lf into food matrix, a functional food can be developed.

Syrovátka ve výživě člověka
Dangová, Taťána
This bachelor thesis is focused on the current use and importance of whey and whey products in human nutrition. Whey, previously considered to be a worthless waste serving predominantly for animal feed, is currently valued for its excellent nutritional properties, especially for its rich protein composition, many of which have demonstrable positive effect on the human organism. The treatment and processing of whey give rise to a wide range of sensory-quality products, which are used not only in the food industry. The thesis describes earlier problems of whey processing, general information concerning its chemical composition, technological operations focusing on the use of membranes processes and the nutritional and physiological significance of individual whey components, which is primarily concentrated on bioactive peptides resulting from hydrolysis of protein.
