METHOD FOR INHIBITING PRODUCTION OF CHLOROPROPANOLS AND CHLOROPROPANOL-FORMING SUBSTANCES IN GLYCERIDE OILS AND FATS

摘要

Provided is a method for inhibiting the production of chloropropanols such as 3-chloropropanediol or 3-chloropropanediol fatty acid esters and chloropropanol-forming substances in glyceride oils and fats. It is possible to inhibit the production of chloropropanols such as 3-chloropropanediol or 3-chloropropanediol fatty acid esters and chloropropanol-forming substances in an oil or fat by reducing the partial glyceride content of the oil or fat or treating the oil or fat with an adsorbent or an alkali prior to the heating step for decolorizing or deodorizing the oil or fat in the process for purifying an oil or fat.
