Abstract
Different levels of apple pomace with different particle size at each level were blended with wheat flour as a source of dietary fiber and the blends were evaluated for their rheological characteristics. Farinographic water absorption increased from 59.1 ml in control to 69.4, 68.2 and 70.2 ml in blends with 11 percent pomace of 30, 50 and 60 mesh, respectively. Wheat flour took 1.9 min. for dough development and the corresponding values for blends containing 11 percent of 30, 50 and 60 mesh pomace were 3.9, 3.8 and 3.8 min., respectively. Mixing tolerance of the blends with 11 percent of 30, 50 and 60 mesh pomace increased to 85.0, 92.5. and 97.5 BU as against 67.5 BU in case of control (wheat flour). Dough stability increased slightly upto 8 percent pomace level but decreased at higher levels of pomace. Gelatinization temperature did not show any remarkable change with pomace incorporation upto 11 percent. Peak viscosity decreased when pomace level was increased from 0 (control) to 5 percent but thereafter it increased. Temperature at peak viscosity did not show much variation between the blends.
