Starches from broad beans, adzuki beans, and kidney beans (forms kzntokz and nagauzura) were subjected to two different methods of gelatinization, alkali gelatinization and autoclaving Amyloses and amylopectins were separated from two sets of gelatinized starches Measurements were made for the yield, iodine coloration, iodine affinity (potentiometric titration), limiting viscosity, and alkali lability number of the two fractions

Amyloses of high iodine affinity could be obtained by autoclaving rather than by alkali gelatinization However alkali lability number of amyloses from autoclaved starches tended to be higher than from alkali-gelatinized starches T h u s amyloses obtained from autoclaved starches might be degraded though high in blue value and iodine affinity
