Eating rate
Tidsramme: Day 1, during consumption of each fixed-portion product sample, from product entering the mouth to full consumption/swallow; approximately 1 minute per sample
|
Fixed-portion (tree crisps of each of five types) that vary in hardness and thickness.

Participant responses to texture
Tidsramme: Day 1, immediately after consumption of each fixed-portion product sample; approximately 1 minute per sample
|
Rating of perceived texture attributes (dryness, hardness, chewiness, flavour intensity, crunchiness, oiliness, aftertaste) using a 0-100 visual analogue scale, and overall liking) with written anchors tailored to the question.
Higher scores reflect a greater subjective feeling of the variable being measured.
