ABSTRACT:
The objective of this study was to investigate how rapid descriptive consumer
analysis using simultaneous presentation of samples compared with monadic
presentation of samples, using both affective and descriptive sensory evaluation
methods. Simultaneous presentation of coffee samples for sensory acceptance
testing, using ranking analysis, was conducted using naïve assessors. In
a separate session, assessors evaluated the same coffee samples, using monadic
presentation and employing the same scales. Similarly, descriptive consumer
analysis, using simultaneous and monadic sample presentation, was conducted
using descriptive attributes chosen by the panel. For RDA (Ranking
descriptive analysis), coffee samples were presented simultaneously (randomised)
to assessors and subsequently ranked. The process was then repeated
using the same assessors; however, samples were presented in monadic and
randomised presentation order. Data accumulated from the study were analysed
by Analysis of Variance (APLSR-ANOVA Partial Least Squares Regression).
Results obtained indicate that simultaneous presentation of samples was
more effective than monadic presentation, as a larger amount of attributes
