Abstract or Summary
  • Starch-structured breads were prepared with five starches-corn, wheat, potato, arrowroot, and waxy maize-used as granular starch with and without addition of 5 percent freshly prepared or retrograded pastes. Highest average scores were for breads made with wheat starch containing retrograded paste and potato starch containing fresh paste. Analysis of variance and correlation coefficients were calculated for the starch properties (amylose content, swelling capacity, and viscosity) and bread characteristics (shape of loaf, grain, chewiness, springiness, and compressibility). The behavior of the various starches differed for all characteristics studied. The differences due to starch were significant at the 1 percent level, and differences due to treatment were significant at the 5 percent level for viscosity at 95° C of the granular and retrograded starch pastes. Bread characteristics were different due to the kind of starch used and the treatment. This work is especially important for people who have food allergies, or who cannot absorb or properly metabolize gluten of wheat flour.
