Abstract (en)

The present invention relates to a process for reducing the level of glycidol and/or glycidyl esters in a preparation of monoglycerides wherein said monoglycerides are prepared by transesterification between glycerol and triglycerides, said triglycerides comprising 10-100% mono-unsaturated aliphatic fatty acid esters, 0-15% poly-unsaturated aliphatic fatty acid esters and 0-90% saturated aliphatic fatty acid esters or by direct esterification between glycerol and fatty acids, said fatty acids comprising 10-100% mono-unsaturated aliphatic fatty acids, 0-15% poly-unsaturated aliphatic fatty acids and 0-90% saturated aliphatic fatty acids, The process comprises at least one holding step in which said preparation of monoglycerides and diglycerides is maintained at a temperature in the range of 140-210°C for a period of time (the holding time) in the range of 10-90 minutes in a separate temperature controlled unit followed by a distillation step.
