Zusammenfassung:The present invention relates to a process for removing metal from metal-containing glyceride oil comprising the steps of: (i) contacting a glyceride oil, comprising chromium, manganese, iron, cobalt, nickel and/or copper in a total amount of from 10 mg/kg to 10,000 mg/kg, with a liquid comprising a basic quaternary ammonium salt to form a treated glyceride oil; wherein the basic quaternary ammonium salt comprises a basic anion selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate; and (ii) separating the treated glyceride oil from a salt comprising the quaternary ammonium cation, providing a treated glyceride oil containing a reduced amount of metals.
