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) admixing the triacylglyceride oil with (1) an auxiliary oil wherein the auxiliary triacylglyceride oil has higher phospholipid and/or wax content than the triacylglyceride oil; and/or (2) the gum extract from an oil; (b) degumming the triacylglyceride oil admixture and/or optionally allowing the insoluble components to crystallize; (c) optionally concentrating the insoluble and crystallized components from the triacylglyceride oil admixture (1) by applying a centrifugational force on the triacylglyceride oil admix and/or (2) by allowing the insoluble and crystallized components to settle by gravity; (d) separating insoluble and crystallized components from the triacylglyceride oil admixture and/or optionally applying one or more processes selected from degumming, physical refining, chemical refining, neutralization, interesterification, bleaching, dewaxing and fractionation; (e) applying heat treatment to the triacylglyceride oil admixture.
