Perception and measurement of sensory qualities found in consumer products. Selecting appropriate sensory methods, experimental design, data analysis and interpretation. Applications of sensory methods in research and the food industry.
FOSC 213 is designed to give students a thorough overview of sensory evaluation. Students will gain understanding in the principles of 'good sensory practice', the importance of being objective and selecting suitable people for use as sensory assessors. The paper will also review discriminative, descriptive and hedonic sensory methodologies used to measure human perception and preference. Students will learn to set up trials that measure the sensory characteristics of food products, including selection of appropriate methods, experimental design, data analysis and interpretation.

- Learning Outcomes
Students who successfully complete this paper will
- Understand the physiological and psychological foundations of sensory functions
- Recognise important considerations in the control of sensory testing environment and test protocols (samples, panels and experimental designs)
- Describe and differentiate different categories of sensory tests and discuss typical applications and their limitations (discrimination tests, descriptive profile methods and acceptance and preference tests)
