Abstract: A method for purification of a triacylglyceride oil comprising the steps: (a) admixing the triacylglyceride oil with an auxiliary trapping agent, wherein the melting temperatures of the triacylglyceride oil and the auxiliary trapping agent are substantially different, wherein the auxiliary trapping agent is soluble in the triacylglyceride oil, and wherein the auxiliary trapping agent is more polar than the triacylglyceride oil; (b) (i) crystallising the auxiliary trapping agent by cooling the mixture of step (a) below the melting temperature of the auxiliary trapping agent, wherein the auxiliary trapping agent has a higher melting temperature than the triacylglyceride oil; or (ii) crystallising the triacylglyceride oil by cooling the mixture of step (a) below the melting 10 temperature of the triacylglyceride oil, wherein the triacylglyceride oil has a higher melting temperature than the auxiliary trapping agent; and (c) separating solid and liquid phases of the product of step (b).

Abstract: A method is provided for preventing or reducing the formation of monochloropropanediols (MCPDs) or monochloropropanediol esters (MCPDEs) in triacylglyceride oil, comprising the steps: (a) concentrating insoluble components in liquid triacylglyceride oil by (i) applying a 5 centrifugational force on the triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or (ii) allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; (b) separating the triacylglyceride oil from the insoluble components; (c) optionally applying additional refining steps and (d) applying heat treatment to the triacylglyceride oil. A purified 10 triacylglyceride oil obtainable by the method of the invention is also provided.

Abstract: A method for purification of a triacylglyceride oil comprising the steps of concentrating the insoluble components in the melted triacylglyceride oil, by applying a centrifugational force on the liquid triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; and separating the triacylglyceride oil from the insoluble components. A triacylglyceride oil obtained by the method of the invention for use in food production is also provided.
