Abstract
The invention relates to a process of process of producing a fermentation product, comprising: liquefying a starch-containing material to dextrins with an alpha-amylase in the presence of an asparaginase and/or an amino acid oxidase; saccharifying the dextrins to a sugar with a glucoamylase; and fermenting the sugar using a fermenting organism.

1-21. (canceled)
A process of producing a fermentation product, comprising:
- (a) liquefying a starch-containing material to a dextrin with an alpha-amylase in the presence of an amino acid oxidase, an arginase, and/or an asparaginase;
- (b) saccharifying the dextrin to a sugar with a saccharifying enzyme;
- and
- (c) fermenting the sugar using a fermenting organism to produce the fermentation product.
A process of producing a fermentation product, comprising:
- (a) treating a starch-containing material with an amino acid oxidase, an arginase, and/or an asparaginase;
- (b) liquefying the treated starch-containing material to a dextrin with an alpha-amylase;
- (c) saccharifying the dextrin to a sugar with a saccharifying enzyme;
- and
- (d) fermenting the sugar using a fermenting organism to produce the fermentation product.
A process of producing a fermentation product, comprising converting a starch-containing material to a dextrin with an alpha-amylase;
- saccharifying the dextrin to a sugar with a glucoamylase;
- and fermenting the sugar using a fermenting organism in the presence of an amino acid oxidase, an arginase, and/or an asparaginase in a single step at a temperature below the initial gelatinization temperature of the starch-containing material.
