The subject covers general principles of sensory analysis. The students will learn sensory methods used in food evaluatin (threshold, discrimination, descriptive and quality tests, scaling, time-intensity, biases, sensory interactions in product evaluation), how to collect, analyze and evaluate sensory data, fundamental principles of sensation, perception, consumer methods, psychophysics, functions of the human senses, as well as data analytical methods in sensory science. During the practice lessons students are given the opportunity to refine their sensory skills and expand their knowledge about their senses and evaluate different kind of food.
