This study demonstrates that the characteristics of the rice flour
used in gluten-free bread-making have a marked influence on the
processing and quality of the products obtained. This influence is
attributed mainly to their effects on dough microstructure. It will
therefore be necessary, both in industry and in research, to clearly
define the characteristics of the flour, using parameters such as
particle size or the amylose/amylopectin ratio, in order to achieve
consistent results. Effects vary depending on the formulation and,
in particular, on the water content. Although proofing times in
studies of gluten-free bread are typically less than 60 min, the
rheofermentometer analysis has shown that, depending on the
characteristics of the flour and the dough, an increase in fermentation
times could lead to an improvement in bread volume, shelflife
and sensorial characteristics. These aspects of the final bread
should be evaluated in future studies
