    摘要: The dry fractionation of oils and fats having a steep dilatation curve (A), i.e. exhibiting a difference in dilatation value at 15.degree. C. and 25.degree. C. of at least 800 mm.sup.3 /25 grammes, in practice is difficult. This problem is solved by mixing oils and fats (A) with triglycerides (B) of such nature that the difference in dilatation of the mixture obtained diminishes substantially. The triglycerides (B) have a difference in dilatation values at 15.degree. C. and 25.degree. C. not exceeding 600 mm.sup.3 /25 g. The weight ratio between fats (A) and fats (B) varies between (10-90):(90-10), preferably (20-80):(80-20) and ideally (40-60):(60-40). The process is e.g. particularly attractive for the dry fractionation of palmkernel oil (fat A) in the presence of palm oil (fat B).
