Abstract
The present invention relates to processes for recovering/extracting oil from fermentation product production processes based on starch-containing material, wherein an alpha-amylase, a high dosage of protease, and optionally a glucoamylase, are present and/or added in liquefaction. The invention also relates to processes for producing fermentation products and to enzyme compositions suitable for use in processes of the invention.
Claims20
A process for producing fermentation products from starch-containing material comprising the steps of:
- a) liquefying the starch-containing material at a temperature above the initial gelatinization temperature using:
- an alpha-amylase;
- and
- at least 2.5 micro gram Pyrococcus furiosus protease per gram dry solids (DS), wherein the protease is the one shown in SEQ ID NO:
- 13 or a protease having at least 90% sequence identity thereto;
- b) saccharifying using a glucoamylase;
- and
- c) fermenting using a fermenting organism.
