Today, enzymes are able to work at lower calcium ion and pH levels, making them much more robust. This allows them to work efficiently under the conditions found in dry-milling, making them more profitable in fuel ethanol production.
During liquefaction, the starch slurry is gelatinized, and starch is broken down to dextrins and small amounts of oligosaccharides. To effectively process the starch in dry-milled grains for the production of ethanol, alpha-amylases are needed to reduce dextrin chain-length and mash viscosity prior to saccharification and fermentation with yeast.
Benefits of using Novozymes' liquefaction solutions:
- Easier processing control
- High solids processing
- Facilitates viscosity reduction
- No added calcium needed
