Generally, an increase in the dough strength would lead
to an increase in the bread volume. Nevertheless this would
be true only up to certain level, above which the bread
volume would decrease with further increase in the dough
strength. Although initially strong dough has higher gas
retention capacity, if the dough is too strong, as is the case
with flour dough made from hard wheat, the amount of gas
produced may not be sufficient to make the dough expand
sufficiently and consequently the bread will have a smaller
volume. In such cases, a reduction in the dough strength
may be desirable.
