Course detail

Laboratory Classes in Sensory Analysis

FCH-MC_SEA_PAcad. year: 2023/2024

The block practical exercise builds on the theoretical knowledge gained in lectures (requirements for assessors, evaluating procedure, conditions for evaluation, applicable methods, etc.). Students will be allowed to test/verify their physical and mental preconditions for sensory evaluation - sensitivity of their senses (taste, smell, sight, or touch) using simple tests that are commonly used in practice for the selection of sensory assessors (according to ČSN ISO 3972: 2013, ČSN ISO 5496: 2009 and ČSN ISO 8586-1: 2015). The tests are performed on model samples of standards. The practices will also include a sensory evaluation of real food samples using various types of sensory tests.

Entry knowledge

To pass this practical course, theoretical knowledge acquired in the course Sensory Analysis is necessary.

Rules for evaluation and completion of the course

Conditions for awarding the course unit credit: 100 % participation in laboratory classes, elaboration and submitting of reports in written form and credit test (at minimum 70 %).

Participation in this practical course is required and controlled.

On the basis of the sensory forms from the individual tests, the students draw up protocols with a summary, statistical processing and discussion of the results.

Aims

The aim of the course is to acquaint students with the practical implementation of sensory evaluation of foods, including the data evaluation and processing.

Students will be prepared to obtain certificate "selected assessor" (according to applicable ISO standards), which entitles the holder to perform a qualified assessment in any sensory laboratory.
As "panel leaders", they will be able to prepare, organize, carry out and evaluate simple sensory evaluations.

Syllabus

The aim of the course is to acquaint students with the practical implementation of sensory evaluation of food, or other natural matrices, including the method of data evaluation and processing. The exercise builds on the theoretical knowledge gained in lecture. Testing of model samples, selected types of food and cosmetics will be performed in the form of 3-hour blocks focused on the following areas:

Week 1:
Operation of sensory laboratory, basics of evaluation, legislation

Week 2 - 8:
Identification of basic tastes and odours
Determination of threshold sensitivity of taste and smell
Test for recognition of taste and smell intensity
Test for determination of taste memory
Test for recognition of colour intensity

Week 9 - 11: Evaluation of real foods
Sensory evaluation of beer, wine, confectionery, dairy products etc.
Sensory evaluation of soap, shampoo, cream etc.

Week 12 - 13:
Presentation of evaluation results, comparison of outputs of different types of evaluation
