Aroma profile of cheese analogues

The aim of this bachelor thesis was to generally characterize cheese analogues and to identify the content of flavor and aroma active ingredients in chosen samples of analogues. Cheeses were manufactured at the Tomas Bata University in Zlín. The introductory section explains what generally processed cheeses and cheese analogues are, including their production. The importance, use and properties of cheese analogues are also described. The microstructure and changes during storage are also mentioned. Particular importance is devoted to their physicochemical and organoleptic characteristics. In the experimental section aroma active compounds of 3 types of processed cheese analogues containing various vegetable fats were identified and quantified. Cheese flavoring compounds were isolated by SPME method (solid phase microextraction) and assessed by gas chromatography. 5 groups of various aromatic compounds in different amounts: alcohols, ketones, aldehydes, fatty acids and esters were found. Finally, the cheese analogues and fats used were compared
