The subject is focused on training of food technologist on the level to be able to combine scientific knowledge of chemical, biochemical, physical and engineering sciences in the branch of fat technology. It provides a basic overview of biochemical changes of stored oilseeds and their impact on a quality of raw oils. Raw oils are produced by unit operation of oil extraction by expelling and solvent extraction. Following refining processes set a preservation target of refined oil nutritional parameters. Oil and fat modifications lead to the production of structured fats with defined structural and textural properties for all food applications. Oleochemical applications are focused on fatty acid production and their derivatives for surfactant and cosmetic production.

Studenti budou umět:

Sledovat, řídit a kontrolovat technologii tuků na úrovni dějů chemických, fyzikálních a inženýrských a z hlediska jejich vlivu na stav výrobku včetně případných změn v nutriční hodnotě.

Následně řešit provozní odchylku technologických parametrů od požadovaných.

Komunikovat s procesními a materiálovými inženýry.
