Abstract (en)
The present invention relates to a process for reducing the level of glycidol and/or glycidyl esters in a preparation of monoglycerides and/or diglycerides prepared by transesterification between glycerol and triglycerides or direct esterification between glycerol and fatty acids. The process comprises least a first holding step in which reaction products from said transesterification or direct esterification are 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, or at a temperature in the range of 70-130°C for a period of time (the holding time) in the range of 1-14 days, in a separate temperature-controlled unit.
