which declined only when fat was reduced by 50%. In their study,
the two levels of fat reduction were higher than in our study,
where the first level of reduction is approximately 15% of fat content,
and the second level of reduction is between 25% and 32%
of fat content depending on the biscuits. For the C Biscuit, surprisingly,
we observed that (F-) was significantly less liked than the
standard biscuit, compared to (F- -), which tended to be less liked.
This could be due to the particularities of this product that will be
discussed in the next chapter.
For two of the three products studied, sugar-reduced variants
are less liked than standard biscuits for both levels of sugar reduction.
These results are consistent with the results of Drewnowski
et al. (1998), on six types of biscuits initially containing sugar contents
similar to ours. The authors observed that reducing the biscuit
sugar content by 25% had an immediate and adverse impact
on overall liking ratings. In our study, the first levels of sugar
reduction were lower than 25%; thus, we observed that sugarreduced
biscuits are even less liked than standard biscuits by
16% or 17% of sugar content. However, for the B Biscuit, both
(S-) and (S- -) were not significantly less liked than the standard
biscuit. This result can be explained by the fact that this biscuit initially
contained less sugar than the other biscuits and that these
variants were less reduced in sugar content. Overall, the most reduced
variant was only reduced by 18% of sugar content.
