This master thesis deals with the determination of bound and free fatty acids in selected types of cheeses with/without „Protected designation of the Europen Union“ and their mutual comparison. The theoretical part focuses on a milk fat, a brief overview of cheeses, protected designation of the Europen Union, lipids, fatty acids and a possibility of their determination. In the experimental part, free and bound fatty acids profile in 12 selected samples of white mold cheeses was determined. The declared amount of total fat was verified. The cheeses were compared by a content of bound and free fatty acids, the profile of fatty acids was compared based on a type of milk used. Finally, the results were statistically treated by PCA method. The method according to ČSN EN ISO 1735 was chosen for extraction of lipids from the cheese samples. A methanolic solution of boron trifluoride was used for fatty acids esterification. The fatty acids methyl esters were determined by gas chromatography with flame ionization detection.
