Title: METHOD FOR PRODUCING REFINED PALM-BASED FAT/OIL, AND METHOD FOR REDUCING GLYCIDOL, 3-CHLOROPROPANE-1,2-DIOL AND FATTY ACID ESTERS THEREOF AND/OR DIGLYCERIDES IN REFINED PALM-BASED FAT/OIL
Abstract:
The present invention addresses the problem of providing a method for producing a refined palm-based fat/oil whereby the contents of glycidol, 3-chloropropane-1,2-diol and fatty acid esters thereof and/or diglycerides can be reduced. Provided is a method for producing a refined palm-based fat/oil that comprises a step for treating a starting palm-based fat/oil by thin film distillation at a temperature of 155-290oC inclusive to give the refined palm-based fat/oil, wherein the total amount of glycidol and fatty acid esters thereof, said total amount being calculated by regarding glycidol and fatty acid esters thereof as glycidol, in the obtained refined palm-based fat/oil is not more than 50% relative to the total amount of glycidol and fatty acid esters thereof, said total amount being calculated by regarding glycidol and fatty acid esters thereof as glycidol, in the starting palm-based fat/oil.
