Resistant starch (RS) displays physiological properties similar to that of dietary fiber. In this study, the physical properties and palatability of bread made with RS type 4 (RS-4, chemically modified starch) were evaluated. Distarch phosphate potato starch, distarch phosphate rice starch, distarch phosphate tapioca starch, phosphated distarch phosphate sweet potato starch, and phosphated distarch phosphate wheat starch were the sources. Wheat flour was replaced with 20% (w/w) RS-4, and the bread was thereby considered as RS-4 added bread. Bread without RS-4 was the control bread. RS-4 added loaves of bread had less specific volume than the control bread. The hardness of RS-4 added bread samples was also higher than that of the control bread. It was observed using a scanning electron microscope (SEM) that RS-4 was not gelatinized in bread. However, RS-4 added bread samples obtained overall acceptability comparable to that of the control bread in the sensory evaluation. It was concluded that differences in the sizes of starch particles added to the bread did not affect palatability. The RS-4 bread with potatoes starch appeared to cause the hardness of the crumb during baking; suggesting that RS-4 derived from cereals would be more suitable for use in bread.
