Sensory Science as a discipline

Sensory analysis is a scientific method used to measure, analyze and interpret responses to products as perceived by the senses of sight, smell, touch, taste and hearing. Sensory analysis can be subdivided into analytical sensory analysis and consumer sensory analysis using the following research techniques:

Type of analysis

Tests

Question of interest

Analytical

Discrimination tests

Are products different in any way?

Descriptive tests

How do products differ in specific sensory characteristics?

Consumer

Affective tests

How well are products liked or which products are preferred?

Sensory Science in the food industry

The new challenges facing the food industry are progressively transforming sensory analysis in such a way that it plays a more proactive role, i.e. generating new product ideas based on unique sensory properties or unique consumer segments identified only through sensory behaviour.

Sensory analysis can therefore be regarded as a critical component of the Product Development and Quality Control divisions of food manufacturing companies.

Sensory Science Facility at SU

The Sensory Science Facility is primarily used for basic research in the field of sensory perception of food and food components. However, the facility also provides scientific and technical services to the South African food and beverage industry. We have experience in

  • Descriptive and discrimination testing using trained panels, i.e. recruiting, training and managing sensory panels and using different descriptive/discrimination test methods for a wide range of food products and beverages
  • Consumer testing, i.e. recruiting the target consumer and testing for sensory acceptance and preference using the hedonic scale or other appropriate tests
  • Statistical analyses of data in collaboration with the ARC Biometry Unit, Infruitec, Stellenbosch
  • Presenting workshops in the theory and practice of Sensory Science to the QC and R&D divisions of food manufacturing companies
