96560 - Sensory Analysis and Food Preferences

Learning outcomes

The student will know the basic elements of sensory evaluation, will distinguish methods and rules for quality evaluation from methods and rules for the evaluation of acceptability and appreciation. In addition, you will know the basic elements for the delivery of a sensory test, the rules and variables to be considered for the recruitment of subjects (juries of tasters/ tasters expert/ or consumers). Among the transversal skills will be learned the concepts of correctness and sharing of the sensory lexicon.

The learning test will be based on a written test of barrier (minimum 18/30) with multiple choice questions about the basics of the course, sensory methodologies, processing of sensory data and an oral test, with questions on topics covered in the program. The weighted average will be calculated according to the mark obtained in the written and oral test, considering that the written test will have a weight of 1/5 of the total. There is one exam for both modules, the written and the oral exam will therefore focus on the notions of both courses and must be taken on the same day.
