As soon as the
panellist clicked the unstructured line scale on the computer
screen, the music (except for the silent condition) played, and the
panellistwas prompted to place the gelato sample into their mouth.
On the 25-s mark, the panellist was instructed to swallow the gelato
sample. The action of clicking on the line scale that appeared on
the computer screen activated the software to record TDS ratings
every second for up to 45 s. All ratings were recorded using FIZZ
sensory data acquisition software (FIZZ Network v2.46b, Biosystemes).
Detailed instructions were given to minimize variation
in consumption behaviour. A compulsory 45-s break in between
samples was provided to allow panellists to drink and rinse their
mouth with filtered water. A limitation inherent in this study, and
one which needs to be considered when judging validity and
generalizability, is the potential for social desirability bias.
