PREVENTION OF MCPD FORMATION IN TRIACYLGLYCERIDE OILS

摘要

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 starting triacylglyceride oil by (i) applying a 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 triacylglyceride oil obtainable by the method of the invention is also provided.
