The sensory measurement provided by a panel of experts to
be objective, it must have the same level of reliability and reproducibility
as the measurement obtained with a measuring instrument. These two essential
criteria are in particular obtained by a sufficient training of the panel. The
aim of this research is to establish a sensory evaluation method more reliable
and reproducible by using a trained panel which helps the company to foresee
the sensory profile of its products. And afterward predict the degree of consumers’
satisfaction of their products. This study, present the methodology followed
to set up an objective sensory evaluation method using a trained panel for the
evaluation of the textile fabrics handle. Indeed a group of judges is selected
and trained to identify and to quantify the perceptions obtained, following
the handling of the fabrics samples of various aspects. A list of 16 handle
attributes is drawn up after principal components analysis. The performance
of the panelists on the level of repeatability is controlled in order to diminish
the variableness of the provided measurements. A control of the panelists’
performance is carried out during the test-retest study using the analysis of
variance. These analyses permitted to set up a group of 10 experts selected
among 15 trained judges according to the importance of their repeatability.
This panel is validated to help the company to foresee the sensory profile of
its products with a subjective evaluation method more reliable and reproducible.
