Previous knowledge expected


Objective (expected results of study and acquired competences)

After successful completion of the course the students know about the basics of fat and oil processing. They have learned about the processing steps of crude oil production, oil refining and modification and understand their principle. They have gained in depth knowledge about lipid chemistry and analyses and changes during processing and storage. Additionally they have deepened their knowledge about the importance of fat and oil for human nutrition. They are able to define the properties of different fats and oils, either native or processed.
