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 protease and a phospholipase are present and/or added during steps (a) to (c). Use of a protease and a phospholipase for increasing oil recovery yields from thin stillage and/or syrup in a fermentation product production process.

The present invention relates to processes for producing a fermentation product, such as ethanol, from starch-containing material; wherein an acid having a pKa in the range from 3.75 to 5.75 is present or added in fermentation so that the acid concentration in fermentation is maintained between above 0 (zero) and 100 mmoles/L fermentation medium and wherein the acid is added before the exponential growth phase of the fermenting organism.
