The present invention relates to deacidification of glyceride oils. The present invention provides a process for removing free fatty acids from glyceride oil, preferably palm oil, containing free fatty acids, said process comprising the steps of: (i) contacting the glyceride oil containing free fatty acids with the basic ionic liquid; wherein the basic ionic liquid has a basic anion selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate; and a cation selected from: [N(R)(R)(R)(R)], wherein: R, R, Rand Rare each independently selected from hydrogen, a Cto C, straight chain or branched alkyl group or a Cto Ccycloalkyl group, wherein said alkyl or cycloalkyl groups are unsubstituted or may be substituted by one to three groups selected from: Cto Calkoxy, Cto Calkoxyalkoxy, Cto Ccycloalkyl, —OH, —SH, —CO(Cto C)alkyl, —OC(O)(Cto C)alkyl, or any two of R, R, Rand Rcombine to form an alkylene chain —(CH)— wherein q is from 3 to 6; and (ii) obtaining a treated glyceride oil having a reduced content of free fatty acid compared to the glyceride oil feed of step (i). 1. A process for removing free fatty acids from glyceride oil containing free fatty acids comprising the steps of: [{'br': None, 'sup': a', 'b', 'c', 'd', '+, '[N(R)(R)(R)(R)],'}, {'sup': a', 'b', 'c', 'd', 'a', 'b', 'c', 'd, 'sub': 1', '8', '3', '6', '1', '4', '2', '8', '3', '6', '2', '1', '6', '1', '6', '2', 'q, 'wherein: R, R, Rand Rare each independently selected from hydrogen, a Cto C, straight chain or branched alkyl group or a Cto Ccycloalkyl group, wherein said alkyl or cycloalkyl groups are unsubstituted or may be substituted by one to three groups selected from: Cto Calkoxy, Cto Calkoxyalkoxy, Cto Ccycloalkyl, —OH, —SH, —CO(Cto C)alkyl, and —OC(O)(Cto C)alkyl, or any two of R, R, Rand Rcombine to form an alkylene chain —(CH)— wherein q is from 3 to 6; and'}], '(i) contacting the glyceride oil ...
