Course detail
FCH-MA_SEAAcad. year: 2023/2024
This course is focused on the problematic of sensory evaluation, i.e. evaluation using human senses. At first students will be familiarized with theoretical principles of physiology and psychology of human perception and with function of single sensory organs. At the second part the practical bases and requirements for sensory evaluation will be discussed in detail: requirements for assessors, evaluating process, suitable conditions for evaluation, methods used etc. Finally, the possibilities of application on various products and use of sensory evaluation in practice are discussed.

Entry knowledge
To start studying the subject, at least basic knowledge of food technology (brief basis of individual food technologies) is required.
Rules for evaluation and completion of the course
The course is completed by a written test - 10 questions aimed at mastering all areas of sensory analysis, the ability to apply in practice (required at least 50% success rate). The results are discussed at the oral exam, incl. possible additional questions - not mandatory, the result of written test can be improved.
The evaluation is in accordance with the ECTS system
Conditions for awarding the course unit credit: active participation in the exercise and preparation of a seminar paper on a selected topic.
.
Attendance at lectures is not compulsory, but is recommended.
Aims
The objective of the course is to make students familiar with complex problematic of sensory analysis with main focus on sensory evaluation of food.
Students will gain basic knowledge of the modern scientific field - sensory analysis; they will be able to prepare, organize, perform and evaluate simple evaluations of various foods.

Syllabus
The aim of the course is to acquaint students with the complex issues of the modern scientific field of sensory analysis, i.e. evaluation using the human senses.
Students will be acquainted with the theoretical bases of the functioning of the human sensory system; in the second part will be discussed in detail the practical implementation of sensory evaluation: requirements to assessors, evaluating process, suitable conditions for evaluation, methods used etc.
As part of the supplementary exercise, students will deepen the theoretical knowledge acquired in the lectures. First of all, the implementation of individual methods of sensory analysis and their practical application - selection of a suitable method, different types of forms, their preparation, control, evaluation of results incl. statistical processing.
Week 1:
Introduction to the problematic, the term "sensory analysis", history, legislation
Week 2 - 4:
Human senses - nervous system, the process of sensory perception, anatomy of individual sensory organs (sight, hearing, smell, taste, tactile senses)
Week 5 - 7:
Requirements to sensory evaluation – human as an evaluator/assessor, equipment of the sensory laboratory, preparation and submission of samples, procedure for sample evaluation
Week 8 - 10:
Overview of sensory methods (discriminant tests, descriptive tests, hedonic tests); statistical processing of sensory analysis results
Week 11 - 12:
Sensory quality, organoleptic properties and their evaluation - appearance, color, smell, taste (flavor), texture
Week 13:
Selected types of food, practical applications.
Guided consultation in combined form of studies
Exercise
