Originální abstrakt

This work deals with the changes in content of fatty acids in long-lasting stored sterilized processed cheeses. Cheeses were stored under special conditions during 23 months. The samples of sterilized processed cheeses were extracted by mixture of solvents (ethanol, diethylether and petrolether). The obtained fat was then saponified by methanolic solution of potassium hydroxide. These methylesthers were analyzed by gas chromatography with flame ionization detection. The content of fatty acids in sterilized processed cheeses was calculated from comparison of measured peaks with standards. Lauric, myristic, palmitic, oleic and stearic acids were the most abundant in cheeses. The yield was measured in these main acids. To summarize the content of fatty acids decreased during time of storage and also by influence of storage temperature higher than in refrigerator.
