Average Expansion ratio of baked breads.
Five photographs of Fig. 4 shows cross sections of baked
breads made from flours of different particle size classifications.
The void size and processability of bread depended on
particle size of flour. Rice bread of particle size 150‒106 µm
contained comparatively small voids and its top was dented.
The breads of flours 75‒45 µm and < 45 µm did not keep
voids. The processability and void forming property was the
best for the flour of particle size 106‒75 µm. The bread
made from it contained small and large round voids showing
wide range of void size distribution
