Alternative methods of sensory testing: advantages and disadvantages

The author describes the process by which the quantitative descriptive analysis (QDA) method was developed, taking into account the time requirements in the context of a rapid method.

Abstract

The growth of sensory evaluation as a product information resource has been significant over the past four decades. With increased competition, companies look for sensory information that can be obtained quickly without compromising the quality of results. This author describes the basic principles and how they are best used to advantage. Particular attention is given to the subject selecting and qualifying process and its effect on test time and the quality of the results. Additional attention is given to descriptive analysis, a methodology that is used in almost every sensory program but in different ways, reflecting how researchers understand the process. The author describes the process by which the quantitative descriptive analysis (QDA) method was developed, taking into account the time requirements in the context of a rapid method.
