Teaching Methodologies
In this curricular unit classical lectures are complemented with practical demonstrations, hands-on experimentation, and sensory analysis in the sensory analysis laboratory.
Learning Results
To explain the physical-chemical and psychophysiological basis of sensory analysis.
Plan and execute sensory analysis tests, analyze sensory test data, report sensory tests
