Proteins from the Great Northern bean (Phaseolus vulgaris L.) were concentrated. The rheological and baking properties of a blend of wheat flour and protein concentrates were compared with those of a blend of wheat flour and bean flour. Addition of the bean flour or protein concentrates to wheat flours caused an increase in water absorption and a decrease in mixing time, dough stability, and mixograph peak height. Load-extension curves for wheat flour/bean flour blends indicated a decreased resistance to extension with increased concentration of the bean flour. For a fixed bean flour level in the blend, however, resistance to extension increased with an increase in resting time. Addition of the bean flour at levels above 10% was detrimental to the dough and bread quality. Breads prepared with added protein concentrates (less than or equal to 10%) were more acceptable than those prepared with added bean flour (less than or equal to 10%), however.
