Objective (expected results of study and acquired competences)

This lecture aims at an understanding of principles and methods of sensory evaluation of foods.

Teaching objective of this course is to teach the fundamentals and practice of planning, implementation and evaluation of methods of analytical and hedonic sensory.

To achieve this objective teaching, practical exercises of significant methods will be integrated.

Through a mix of knowledge and skills exchange, students are, after completion of the course, able to analyze problems in the field of sensor technology, to select adequate methods and apply using the principles of Good sensory laboratory practice, and finally interpret the results effectively.

Students are able to apply general principles of sensor technology in concrete situations and reach by applying and combining multiple sensory methods to new insights.
