Abstract

Fenugreek gum (extruded and non-extruded) was substituted for wheat flour at 0%, 5% and 10% (w/w) and the rheological effects and breadmaking characteristics were determined. Bread containing fenugreek gum (FG) at 5% and 10% showed volumes and texture comparable with a control bread. Quality was high due to sheeting the dough twice as well as the use of the three-fold-turn puff pastry laminating method during processing of dough, instead of the standard rounding of dough. The three-fold-turn method is believed to have caused a higher incorporation of air into the dough as well as facilitated better distribution and incorporation of the fenugreek gum into bread dough. Extruding FG also improved its solubility in bread. Fenugreek gum (FG) resulted in an increase in dough farinograph water absorption compared with the control, but extruding the gum caused an even greater increase in water absorption when compared with the non-extruded gum. The addition of FG to bread dough caused an increase in G' and G″. Starch pasting using RVA showed an increase in peak viscosity, final viscosity, breakdown and setback in a dose-related response when compared with a control. © 2011.
