METHOD FOR REDUCING CHLOROPROPANOLS AND FORMATIVE SUBSTANCE THEREOF GLYCIDOL FATTY ACID ESTERS IN GLYCERIDE OILS

摘要

It is an object of the present invention to reduce 3-chloropropanediol, 3-chloropropanediol fatty acid ester and glycidol fatty acid ester as a forming material of chloropropanol in the oil. Deg.] C, or a basic activated carbon treatment, or an aqueous solution of an organic acid is mixed and dehydrated or mixed with a solvent under reduced pressure at 50 to 180 [deg.] C, and then a solvent or a low melting point fraction of a solvent and a glyceride The chloropropanol and the glycidol fatty acid ester, which is a forming material thereof, in the glyceride oil can be reduced. Further, the glycidol fatty acid ester in the glyceride retention can be reduced by contacting the acid with the glyceride oil after the decolorizing and deodorizing process.
