Process for separating solid fatty material from a triglyceride oil, which comprises the steps: a) heating the oil or a solution of the oil in an inert solvent until no longer a substantial amount of solid material is present; b) adding a crystallisation modifying substance to the oil or to the solution of the oil; c) cooling the oil resulting in crystallising a solid stearin phase besides a liquid olein phase and d) recovering the stearin phase by separating it from the olein phase, characterized in that the crystallisation modifying substance is a polysaccharide being an inulin or phlein with a molecular weight of 500-3990 Da, preferably 1300-2500 Da, of which at least 50 % of the hydroxyl groups on the saccharide subunits are connected to (C8-C24) unbranched alkyl chains and the remaining hydroxyl groups, optionally, are connected with a (C1-C7)-alkyl chain, preferably in the form of an acetic ester.
