Oil purification process

A method for purification of lipid material, the method comprising:

• a) providing a feed of lipid material;
• b) heat treating the lipid material without added water or other solvent wherein heat treatment takes place at any temperature in a range of 240° C. to 280° C., and wherein a residence time in step b) is maintained during a period of 1 minute to 30 minutes and wherein the lipid material has not undergone any pre-treatment prior to heating and wherein the heat treatment is performed in a pressure chamber;
• and
• c) post treating the lipid material by a water treatment step which is performed in a presence of water in an amount of 1 wt % to 3 wt % to a volume of the lipid material;
• wherein water treatment step c) is performed at a temperature of 130° C. to 220° C., to thereby reduce an amount of phosphorous and/or metal compounds in the lipid material.
