Özet
Influences of alfalfa powder concentration and granularity on the dynamic theological properties of alfalfa-wheat dough was studied. Frequency sweep tests at 25 degrees C and 80 degrees C and temperature sweep tests from 25 degrees C to 80 degrees C were applied to wheat dough samples. Elastic moduli (G') and viscous moduli (G '') of the alfalfa-wheat dough at 80 degrees C were higher than those of the alfalfa-wheat dough at 25 degrees C. The viscoelastic moduli (G' and G '') of the alfalfa-wheat dough at 80 degrees C showed less frequency dependence compared to those of the samples at 25 degrees C. The viscoelastic moduli (G' and G '') of alfalfa-wheat dough increased with the increasing of alfalfa powder concentration from 0% to 10% and decreased with further increase in alfalfa powder concentration from 10% to 20% at 25 degrees C. All the alfalfa-added samples showed a delay in the dough gelatinization temperature comparing with the control sample. On the other hand, the viscoelastic moduli (G' and G '') increased with the increase of alfalfa powder granularity distributed from 80-100 to 40-60 mesh. (c) 2008 Elsevier Ltd. All rights reserved.
