Conversion of starch from dry common beans (Phaseolus vulgaris L.) to ethanol

▶ Dry beans were used in a starch-to-ethanol process modeled after the corn dry grind ethanol process. ▶ Average ethanol yield for the eight bean types examined was 92% of the theoretical maximum. ▶ The residual solids from ethanol fermentations contained 37.1-43.6% (dry basis) crude protein.
