Extrusion of corn for ethanol fermentation

  • Published:
Biotechnology Letters Aims and scope Submit manuscript

Summary

Extrusion and conventional cooking of corn for ethanol production were compared. Extrusion processing requires less energy and water than conventional cooking methods. Optimal autogenous extrusion conditions were determined as: feed rate=5.2kg/min, moisture=15% (wet basis) and extrusion discharge temperature=1600 C. Improved yields of glucose and ethanol from the extruded samples were found over conventionally cooked samples.
