Abstract
The present invention relates to using high oil corn to make a biochemical such as ethanol. More particularly, the invention relates to methods of making a biochemical using relatively low temperature saccharification followed by fermentation or simultaneous saccharification and fermentation of high oil corn.
Claims21
A method of producing a biochemical and corn oil from corn, the method comprising:
- providing a feedstock comprising milled whole corn grain, wherein the milled whole corn grain comprises corn oil and starch, wherein the milled whole corn grain is derived from milling a first whole corn grain and a second whole corn grain, wherein the first whole corn grain has an oil content of 4 percent or less on a dry weight basis and the second whole corn grain has an oil content of 5 percent or greater on a dry weight basis, wherein the milled whole corn grain comprises at least 5 percent by weight of the second whole corn grain, and wherein a total of the amount of the first whole corn grain and the amount of the second whole corn grain has an average oil content of greater than 4 percent on a dry weight basis;
- adding water to at least a portion of the feedstock to form an aqueous composition, wherein the aqueous composition comprises corn starch and corn oil from the feedstock;
- saccharifying at least a portion of the corn starch present in the aqueous composition into glucose;
- fermenting glucose present in the aqueous composition to produce a biochemical;
- and
- recovering corn oil from the aqueous composition after fermentation.
