Efficient ethanol plants can convert 90-97 percent of the corn’s starch content to ethanol. However, not all batches of corn leave the same amount of starch residue. Studies of ethanol yields from different batches show significant variability (Dien et al., March 2002). Even though it is the starch that is turned into ethanol, researchers have been unable to find a correlation between starch content (or even starch extractability) and the final yield of ethanol (Singh and Graeber). Researchers believe some starches are in a more available form (Dien et al., March 2002). They do not know, however, what makes the starch break down easily to simple sugars and. | BISPHENOL A ALTERNATIVES IN THERMAL PAPER DRAFT FOR PUBLIC COMMENT July 2012 DO NOT CITE OR QUOTE us.
