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.

A method for purification of a triacylglyceride oil, wherein a quantity of organic chlorinated precursors of monochloropropandiol esters (MCPDEs) is reduced in the purified triacylglyceride oil compared to the triacylglyceride oil, the method comprising:
- (a) concentrating insoluble components in a liquid triacylglyceride oil by
- (i). applying a centrifugational force on the liquid triacylglyceride oil whilst maintaining a temperature of the liquid triacylglyceride oil above a melting temperature of the triacylglyceride oil;
- and
- (ii). allowing the insoluble components to settle by gravitational force whilst maintaining the temperature of the liquid triacylglyceride oil above the melting temperature of the triacylglyceride oil;
- and
- (b) separating the liquid triacylglyceride oil from the insoluble components.
