This thesis deals with the identification and quantification of free and bound fatty acids in model cheese samples of the Moravský bochník type, which were produced at Tomas Bata University in Zlín by a standard technological procedure. In a theoretical part of the thesis, the issues of lipids, fatty acids, as well as the characteristics of high cooked cheeses including Moravský bochník, microbial cultures used in their production, and the possibilities of fatty acids determination are summarized. The ČSN EN ISO 1735:2005 method was chosen for the lipid extraction from cheese samples. Present free and bound fatty acids were identified and quantified by gas chromatography with flame-ionization detection after conversion to methylesters by acid esterification with bortrifluoride as a catalyst. In total 32 fatty acids were identified in cheese samples, the highest amount of caproic, caprylic, capric, lauric, myristic, palmitic, stearic and oleic acids.
