Abstract

The present invention is directed to methods for producing high levels of alcohol during fermentation of plant material, and to the high alcohol beer produced. The present invention is also directed to methods for producing high protein distiller'"'"'s dried grain from fermentation of plant material, and to the high protein distiller'"'"'s dried grain produced. The present invention also relates to reduced stack emissions from drying distillation products from the production of ethanol.

Claims

1. A distillers dried grain comprising:

29.7 to 38.9% of protein; and

9.92 to 22.24% of starch.

2. The distillers dried grain of claim 1 comprising:

29.7 to 38.9% of protein;

9.92 to 22.24% of starch;

10.9 to 21.3% of fat; and

residual fermentation and saccharification enzymes.

3. The distillers dried grain of claim 2 wherein the residual fermentation and saccharification enzymes comprise an acid fungal amylase and a glucoamylase.
