Abstract

The present invention is directed to a basic ionic liquid treatment for removing chloropropanol and/or glycidol, or their fatty acid esters, from glyceride oil, as well as a process for refining glyceride oil which includes the basic ionic liquid treatment. The present invention also relates to uses of the basic ionic liquid and glyceride oil compositions obtained from the ionic liquid treatment.
