Compared to HPMC-treated barley bread (shape score: 7) the shape of GS (8.12) and NS (7.25) bread had higher scores, implying a better shape than HPMC-barley bread. In contrast, RS (3.62) and SS (1.75) breads scored about half that of the reference. The addition of HPMC to RS bread increased the shape score from 3.62 to 6.00.
There were significant differences in crumb colour among the samples that followed the same order as the instrumental colour value. Non-heat-treated breads scored 2 or 3 times darker than did white bread (crumb colour score: 1) by the panel and heat-treated breads scored 7 to 8 times darker than did white bread.
