A pseudo-steady state fractionation of a poly- morphic fat, resulting in a product which is in a kinetically stable crystal form is performed in a way that a .sigma.-value is maintained below 0.5, formula (I) wherein S c being: the percentage solids in crys- talliser at crystallisation temperature, S E being: the percentage solids after stabilisation for 48 hrs at exit temperature of crytalliser.
