Abstract
The present invention relates to a process for preparing a refined vegetable oil. It relates to a process for reducing the content of free chloropropanols and chloropropanol fatty acid esters in a vegetable oil, and it is comprising the following steps in order: a) refining a vegetable oil, wherein the refining is comprising at least a deodorization step at a temperature below 230° C., and subjecting the refined vegetable oil to a short path evaporation, and collecting a vegetable oil having a content of free chloropropanols and chloropropanol fatty acid esters of not more than 500 ppb and a color expressed as its red component equal or below 3.0.
Claims14
A process for reducing the amount of free chloropropanols and chloropropanol fatty acid esters in a vegetable oil, the process comprising:
- refining a vegetable oil, wherein the refining comprises:
- bleaching comprising adding a bleaching agent in an amount from 2% to 10% based on weight of vegetable oil;
- and
- deodorization performed at a temperature of less than 230° C.;
- subjecting the vegetable oil to a short path evaporation;
- and
- collecting the vegetable oil having the content of free chloropropanols and chloropropanol fatty acid esters of not more than 500 ppb and a color expressed as its red component equal or below 3.0;
- wherein the vegetable oil is derived from palm oil.
