Hardness was inversely correlated
with specific volume (r = 0.8931; P 6 0.001), thus a lower
bread specific volume results in greater hardness due to denser
crumb and more compact cells. The crumb hardness of the rice
breads obtained in this study was much lower than that reported
for commercial gluten free breads (Matos & Rosell, 2012), probably
due to the use of starch instead of flour.
