A method of recovering oil, which includes (a) converting a starch-containing material into dextrins with an alpha-amylase; (b) saccharifying the dextrins using a carbohydrate source generating enzyme to form a sugar; (c) fermenting the sugar in a fermentation medium into a fermentation product using a fermenting organism, wherein the fermentation medium comprises a xylanase and a pectinase; (d) distilling the fermentation product to form a whole stillage; (e) separating the whole stillage into thin stillage and wet cake; and (f) recovering the oil from the thin stillage.
