Title:
METHOD FOR REDUCING CHLOROPROPANOLS AND CHLOROPROPANOL-FORMING SUBSTANCES IN GLYCERIDE OIL OR FAT
Document Type and Number:
WIPO Patent Application WO/2011/055732
Kind Code:
A1
Abstract:
Disclosed is a method wherein glyceride oil or fat after the bleaching and deodorizing step is brought into contact with an alkaline aqueous solution and then purified, thereby reducing chloropropanols such as 3-chloropropanediol or 3-chloropropanediol fatty acid esters and chloropropanol-forming substances in the glyceride oil or fat.
Specifically disclosed is a method wherein when glyceride oil or fat after the bleaching and deodorizing step is brought into contact with a solid alkaline substance at a weight ratio of 150-750 ppm and then purified, the SFC (at 20˚C and/or 35˚C) of the oil or fat to be obtained is set to be 0.9-1.1 relative to the SFC (at 20˚C and/or 35˚C) of the oil or fat that is purified without being brought into contact with the solid alkaline substance. Consequently, chloropropanols such as 3-chloropropanediol or 3-chloropropanediol fatty acid esters and chloropropanol-forming substances in the glyceride oil or fat can be reduced.
