Learning outcomes of the course unit
The student will gain applied knowledge and understanding about the
physiological and molecular mechanisms of flavour perception and about
the formation of taste and aroma compounds in food.
Fundamentals in organic chemistry, analytical chemistry and food
Course contents summary
- Flavour perception and evolutive meaning. - Interactions between
flavour molecules and receptors. -Sweet molecules and structural
requirement for sweetness perception -Natural and artificial sweeteners. -
Bitter molecules and structural requirements for bitterness perception. -
Structure of Umami, Salty and Sour molecules. - Non-taste perception in
mouth: astringency, hot, refreshing. - Aroma perception. -
Structural requirements of odor active compounds, aroma value. - Aroma
molecules naturally present in food. - Aroma molecules generated by
cooking, fermentation, processing. - flavour profile of several foods: wine,
cheese, coffee, tea, chocolate. - Food pairing according to active aroma
molecules. - Aroma substances and legislative issues. - Artificial tongue

A number of case studies will be illustrated, with a particular attention to
traditional foods; this will allow the student to develop making
judgements and communication skills.
