Flour replacement at different levels (from 2.5 up to 7.5%) by
inulin change dough machinability, viscoelasticity and breadmaking
performances. The trend and the extent of effects of fibre on the
breadmaking process (mixing, proofing, baking) depend on inulin
type in the blend and on the extent of flour substitution. Addition of
inulin to both weak and moderately strong flours resulted in
a strengthening effect. Caution should be paid to inulin HP because
of the adverse increase in solid-like properties of the dough, which
may reduce expansion during fermentation and baking. Enrichment
with inulin ST led to lower changes in linear viscoelastic
properties of dough than inulin HP and had no negative effects on
crumb hardness and volume of bread prepared with flour suitable
for breadmaking (MS). Nevertheless, addition of inulin ST over 5% is
not recommended because of sweet taste. The present study has
indicated that breads made with about 5% inulin ST and HP had
high sensory acceptance. Therefore, the addition of inulin could be
an effective way to produce functional white flour bread without
changing negatively its desirable physical properties. Further
studies are needed to evaluate changes in fibre-enriched bread
characteristics during storage
