Abstract
A process of recovering oil, comprising (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; (d) recovering the fermentation product to form a whole stillage; (e) separating the whole stillage into thin stillage and wet cake; (e′) optionally concentrating the thin stillage into syrup; (f) recovering oil from the thin stillage and/or optionally the syrup, wherein a phospholipase is present and/or added during steps (a) to (c). Use of phospholipase for increasing oil recovery yields from thin stillage and/or syrup in a fermentation product production process.
