Course detail

Sensory food analysis

FCH-MCO_SAPAcad. year: 2012/2013

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 of sensory evaluation in food practice are briefly noticed.
Practical laboratory classes apply the acquired theoretical knowledge. Students will be allowed to try sensitivity of their senses (taste, smell, sight, touch) using simple special tests (ČSN ISO 3972:2001, ČSN ISO 5496:2009 and ČSN ISO 8586-1:2002). Further single special sensory methods will be practised and applied to various types of food.

Learning outcomes of the course unit

Students will acquire the basic knowledge about modern scientific branch - sensory analysis.
Theoretical knowledge acquired:
- human senses – perception process, anatomy and function of single sensory organs
- requirements for sensory evaluation – human assessor, equipment of sensory laboratory, preparation and submitting of samples
- the overview and application of sensory methods
- the possibilities of statistical evaluation of results of sensory analysis
- process of sample evaluation
- use of instrumental methods for assessment of sensory quality of food
Owing to the practical laboratory classes students will be able to organize, prepare and conduct simple sensory evaluations of various types of foods or cosmetics.

Prerequisites

Food technology - the brief base of particular food technologies.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Lectures with support of e-learning, practical laboratory classes in sensory laboratory.

Assesment methods and criteria linked to learning outcomes

Conditions for awarding the graded course-unit credit:
a) written part - 10 questions focused on all areas of sensory analysis, ability of practical applications
b) oral part - possible supplementary questions
c) active attendance at laboratory classes, delivery of protocol
