According to our hypothesis ii, reduced variants were less liked
than standard biscuits, and for a similar level of reduction, sugarreduced
biscuits were more disliked than fat-reduced biscuits. By
comparing the results of the perception and of the liking scores,
the less liked variants were mainly those only perceived as less
sweet, and, to a lesser extent, less sweet and less fatty or less crispy
than the standard biscuits. In contrast, variants only perceived as
less fatty are not significantly less liked, even if it tended to be
for one variant. These results confirm our hypothesis iii, according
to which sweetness is the key sensory attribute that determines
liking, which is in agreement with other studies on fat- and/or
sugar-reduced biscuits (Drewnowski et al., 1998) or chocolate
puddings (Geiselman et al., 1998).
