PCT No. PCT/EP94/00639 Sec. 371 Date Dec. 13, 1995 Sec. 102(e) Date Dec. 13, 1995 PCT Filed Mar. 4, 1994 PCT Pub. No. WO94/21762 PCT Pub. Date Sep. 29, 1994The present invention relates to a process for the preparation of degummed glyceride oils, which comprises applying an acid degumming treatment to a crude glyceride oil which has not substantially been exposed to enzymatic activity. Preferably such crude glyceride oil has been obtained by heating and pressing glyceride oil containing vegetable material, optionally preceded by a cold pressing step, where the heating comprises an exposure of the vegetable material to a temperature of 30 DEG -80 DEG C. for 0.1-20 minutes, preferably for 0.1-15 minutes, more preferably 0.1-5 minutes, and then to a temperature of 80 DEG -140 DEG C., preferably 90 DEG -110 DEG C. for 1-60 minutes, preferably 15-20 minutes. Residual phosphorus levels of <7 ppm and even <2 ppm can be easily and consistently attained.
