Abstract
Vegetable oil compositions, as an example, corn oil, having an elevated lower alkyl ester content above about 7% weight percent of the total weight of the oil composition, and uses thereof are provided.
Claims8
A method to increase the utility of corn oil obtained from fermentation by chemical modification of the corn oil, the method comprising:
- providing an aqueous composition including ground corn material and corn fat;
- treating the aqueous composition with an enzyme to produce glucose;
- fermenting the glucose in the presence of yeast and a composition including an exogenous esterase in an amount and under conditions which produce ethanol and the corn oil;
- and
- wherein the corn oil has an increased ethyl ester content and lower viscosity as compared to a corn oil obtained from a process that does not include exogenous esterase during fermentation.
