Learning Objectives
Knolewdge acquired: Factors affecting consumer liking and preference for food products;
Competence acquired (at the end of the course):
Management of sensory evaluation and consumer testing resources, activities, and their interaction with other business units; exploratory research techniques. To be able to apply a method for studying consumer perception of food quality. To be able to study hedonic and sensory consumer expectations.
To be able to apply multivariate statistical methods in studying consumer preference.
Skills acquired (at the end of the course): Being able to analyse the complexity of a phenomenon and to identify relevant individual factors. Being able to develop multidisciplinary approaches in solving complex problems. Being able to integrate tools, techniques and methods from different scientific disciplines. Being able to define what kind of specific competence are needed in solving complex problems
