Triglyceride oils are degummed according to a two-stage process, in which in the first step a substantially concentrated solution of an acid or an anhydride, having a pH of at least 0.5 as measured at 20 DEG C in a one molar aqueous solution, is dispersed in the oil, and in a second step 0.2 to 5 wt.% of water is dispersed in the mixture obtained and an aqueous sludge is separated from the oil after the water has been in contact with the oil-acid-mixture for at least 5 minutes at a temperature below 40 DEG C. |
