Course Description

Foodomics

Program

Ecotechnologies, third-level study programme

Lecturers:

prof. dr. Urška Vrhovšek

Goals:

This course aims to give to the students a knowledge how to perform a metabolomic experiment, from start to finish. It covers study design, sample preparation, the use of mass spectrometry for global profiling and targeted methodologies and data analysis.

Content:

The food metabolome - i.e. the entirety of all low molecular weight compounds in a specific food. It can be extremely complex, often comprising several thousand chemical species. Food metabolomics can nowadays be considered as a valuable tool for the assessment of food quality, food safety, food tracability and food-related health effects. Students will meet with different metabolomic approaches in the analysis of diverse classes of food metabolites. They will get a knowledge how to properly design an experiment for metabolomics studies. They will learn about different sample preparation techniques, and quality control for metabolomics studies. In the frame of the course, several analytical technologies applied in the untargeted and targeted metabolomics studies: liquid chromatography, gas chromatography coupled to mass spectrometry and also some basic information about NMR based metabolomics will be introduced. The students will learn the basics about the data mining methodologies of a complex data sets and the knowledge how to extract biologically meaningful information.
