Formulating a new high fiber rusk for production on commercial scale.
Three formulas were prepared for production of high dietary fiber rusk on production scale. The preparation was based on partial replacement of wheat flour with different levels of wheat bran, barley and maize flours. Chemical composition, dough characteristics, baking performance and sensory evaluation of rusk were investigated. A remarkable improvement in minerals (calcium and phosphorus) and dietary fiber was achieved. Formulas 'A' and 'B' contained about 3 folds dietary fiber and formula 'C' contained about 4 folds compared with control rusk. The rheological properties of the dough were affected by the fiber incorporation in all suggested formulas. Baking performance showed that all rusk formulas were lower in loaf volume and higher in loaf weight than control sample. Physical measurements and sensory characteristics of rusk indicated generally that all formulas were acceptable, but formula B which contains 70 g wheat flour +10 g wheat bran +10 g maize flour +10 g barley flour seems to be generally superior in symmetry of shape, crust and crumb colour, crumb texture, break and shred, aroma and taste.
