Sensory analysis and assessor motivation: Can computers make a difference?

The potential value of using computerised systems in sensory analysis is discussed in this preliminary study. This included assessing the impact on panel motivation, and on the consistency of responses made through a comparison of manual and computerised methods. Accuracy and consistency appeared to improve significantly as the tests progressed, and on completing the session computer accuracy was superior. Hedonic tests Provided substantial variation, although generally deviations in computer responses mere lower. The affective tests produced a more erratic response pattern, although this may have been expected, due to the greater subjectivity involved. Finally, a focus group provided valuable reinforcement of results and clarification of assessor preferences. The computerised sensory system was unanimously preferred and may Provide an effective tool in maintaining motivation levels. However, careful and consistent management is still required if results are to be meaningful. Copyright (C) 1996 Elsevier Science Ltd
