Course detail

Sensory food analysis

FCH-MCO_SAPAcad. year: 2020/2021

This course is focused on the problematic of sensory evaluation, also evaluation using human senses. At first students will be informed about theoretical principles of physiology and psychology of perception and about function of single human sensory organs. At the second part the practical performance of sensory evaluation will be discussed in detail: requirements for assessors, process of evaluation, suitable conditions for evaluation, suitable methods 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 of modern scientific branch - sensory analysis, they will be able to prepare and make simple evaluation of food or cosmetics samples.

Prerequisites

Food technology - characteristics of food industry, brief base of particular food manufactures.
