Abstract
The present invention relates to processes for producing fermentation products from starch-containing material, wherein a bacterial alpha-amylase, a raw starch hydrolyzing alpha-amylase and a carbohydrate-source generating enzyme are present and/or added during liquefaction. The invention also relates to compositions suitable for use in processes of the invention.
Claims20
A process for producing a fermentation product comprising the steps of:
- (a) liquefying a starch-containing material at a temperature in the range from 60-80° C. using:
- a bacterial alpha-amylase;
- a raw starch hydrolyzing alpha-amylase;
- a carbohydrate-source generating enzyme having a heat stability at 70° C., pH 5.3, of at least 70%;
- (b) saccharifying using a carbohydrate-source generating enzyme;
- (c) fermenting using a fermenting organism.
