1. A process for increasing ethanol yield from grain comprising the steps of:
- (a) mixing a grain-based material with water and enzyme for a period of 15 to 60 minutes at a temperature of 130 to 190°
F. to form a pre-gelatinized grain-based liquid medium; and
(b) subjecting said grain-based liquid medium at a temperature of 130 to 190°
F. to cavitation activation energy not less than 0.4 kJ per kilogram of said grain-based liquid medium to enhance the activity of said enzyme in said grain-based liquid medium.

Abstract
A process for increasing ethanol yield from grain comprising mixing grain, water and enzyme to for a grain-based liquid medium. The grain-based liquid medium is passed through a cavitation device at a velocity and pressure capable of generating a cavitation activation energy of at least 0.4 kJ per kilogram of grain-based liquid medium to enhance the activity of the enzyme and increase ethanol yield.
