Grain Alcohol Enzymes

Enzymes are primarily used in the alcohol industry to hydrolyze large starch molecules to simple sugars. Typically this is accomplished in a two-step enzyme catalyst process called liqefaction and saccharfication. Enzymes also have a major role to play in viscosity reduction, fermentation enhancement and improvement in the quality of co-products.

Process Challenges

  • High viscosity with wheat, rye, triticale and barley processing
  • High raw material / process cost
  • Poor alcohol yield
  • Slow fermentation rates
  • High residual starch levels at the end of fermentation
  • Stillage recycle reduces liquefaction pH
