Course detail

Sensory food analysis

FCH-MCO_SAPAcad. year: 2021/2022

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 food types and use of sensory evaluation in food practice are discussed.

Learning outcomes of the course unit

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 or other natural materials.

Prerequisites

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

Co-requisites

The course is focused especially on application in food industry, however, general bases are applicable in many other areas (cosmetics, environment etc.).

Planned learning activities and teaching methods

The course uses teaching methods in form of lecture and classes - 2 teaching hours per week; e-learning system (LMS Moodle) is available to students.

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 (at least 50% success)
b) oral part - possible supplementary questions
