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

摘要

The present invention addresses the problem of providing a method for producing a refined palm-based fat and/or 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 and/or oil that comprises a step for treating a starting palm-based fat and/or oil by thin film distillation at a temperature of 155-290oC inclusive to give the refined palm-based fat and/or 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 and/or 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 and/or oil.
