<p>The 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 30-80 °C for 0.1-20 minutes, preferably for 0.1-15 minutes, more preferably 0.1-5 minutes, and then to a temperature of 80-140 °C, preferably 90-110 °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.</p> |
