Kinetic of lactic acid formation in kefir

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
