Some Methodological Issues in Product Testing
Abstract:
The development of food products follows a lengthy path culminating in consumer acceptance testing. The product tests are very complex, with numerous issues to consider to obtain clear, unbiased measurements of consumer preference. These issues cover areas of product technology, respondents' sensory abilities and measurement of reaction to products. This paper is strictly concerned with the third issue. The objective is to discuss four interrelated statistical/methodological facets of food product testing. Consideration of these facets can help strengthen the interpretability of the test results.
