Kinetic of lactic acid formation in kefir
Fajtl, Zbyněk ; Vítová, Eva (referee) ; Veselá, Mária (advisor)
This bachelor thesis deals with the kinetic production of lactic acid and consumption of lactose in the kefir fermentation from one type of milk under the same conditions. The theoretical part contains information on kefir and kefir grains, lactose intolerance, antimicrobial properties and high-performance liquid chromatography. The experimental part describes the methods and procedures used in the manufacture of kefir itself, the determination of lactic acid and lactose. Kefir samples were tested at precise time intervals for lactose, lactic acid and lactobacilli. The data was graphically evaluated and commented. The results of this work may be beneficial for consumers with lactose maldigestion and for consumers searching for qualite source of lactobacilli for enhancing their gut microflora.

Study of yogurt composition in process of its preparation
Fajtl, Zbyněk ; Vítová, Eva (referee) ; Veselá, Mária (advisor)
This thesis deals with the study of yogurt preparation and changes during its storage. The theoretical part contains information about parameters affecting both the preparation and properties of the final product. The experimental part describes methods and procedures used for determination of critical parameters such as lactic acid, lactose, glucose and galactose concentrations (HPLC-RI), amounts of streptococci and lactobacilli. The data was graphically evaluated and commented on. The work also included sensory analysis in which the prepared yogurt was compared with commercially available products. The results of this work can serve both consumers and smaller yogurt producers.
