Evaluation of Corn Distillers' Dried Grains Defatted with Supercritical Carbon Dioxide.

Corn distillers' grains (CDG) were extracted with supercritical carbon dioxide (SC-CO2) and with SC-CO2 plus water and/or ethanol, at pressures of 63,600, 68,000, and 81,600 kPa (9,350, 10,000, and 12,000 psi) and at temperatures around 84 and 102 C. The CDG extracted with SC-CO2 had lower fat and higher neutral detergent fiber contents than untreated CDG. Defatted CDG had acceptable flavor scores. CDG treated with SC-CO2 may thus have potential as a food ingredient with high protein and dietary fiber contents.
