Effect of water and PHGG levels on bread firmness is shown in
Fig. 2a. Firmness of bread first decreased slightly and then
increased with increase in PHGG level at low as well as high water
levels. An increase in PHGG level increased the firmness of the
bread due to the diluting of gluten by the PHGG. The results are in
accordance with the previous finding in which bread was fortified with wheat fiber and oat fiber (Poltorak and Zalewska, 2007). Effect of water level on bread firmness at higher PHGG levels was more prominent than at the lower PHGG levels. At lower PHGG levels, the firmness of bread first increased and then decreased with increase in water level. At higher PHGG levels, firmness of bread remained almost unchanged upto 60% water level but beyond 60%, bread firmness decreased with increase inwater level. This may be due to increased water absorption which leads to increased crumb softness.
