EXTRACTION OF OIL FROM CORN DISTILLERS DRIED GRAINS WITH SOLUBLESPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Transactions of the ASAE. 41(6): 1775-1777. (doi: 10.13031/2013.17322) @1998Authors: N. Singh, M. Cheryan Keywords: Oil extraction, Corn, Dry-grind The feasibility of extracting crude corn oil from distillers dried grains with solubles (DDGS) of corn was studied using anhydrous ethanol as a solvent. Total solids, fat, glycerol, and protein extracted from DDGS increased with increased ethanol-to-DDGS ratio at 50C and an extraction time of 30 min. However, ethanol-to-DDGS ratios above 6 mL ethanol per g DDGS did not significantly increase the amount of oil extracted, but did increase glycerol extraction. At the optimum ethanol-to-DDGS ratio of 6, about 50% of the crude corn oil can be extracted from DDGS in a single extraction step. (Download PDF) (Export to EndNotes)
