From Fig. 1, it is obvious that the quantity and type of cassava flour in the bread recipe as well as the addition of fibers affected bread volume, pan bread shape and crumb uniformity and porosity. To assess the effect of batch variation, two times two bread prod- ucts made from identical recipes but produced from different dough batches (1 1⁄4 6 and 14 1⁄4 16) were included in the study.
