Abstract
The present invention relates to a process for the removal of free fatty acids from glyceride oils, especially palm oil. In particular, the present invention is directed to a process wherein specific ionic liquids are utilised for removing free fatty acids contained in glyceride oils, preferably palm oil, such that a glyceride oil, having a reduced content of free fatty acids may be obtained. The invention also relates to treated glyceride oil compositions, preferably treated palm oil compositions, comprising certain ionic liquids to prevent build-up of free fatty acids in stored oil.
