- 摘要：
The invention relates to a process for separation of a processed vegetable fat (PVF), wherein said process comprises the steps of: in a distillation step (DIS), distilling the processed vegetable fat (PVF) into a distillate part (DPT) comprising stearic and oleic acid and/or esters thereof, and a distilled vegetable fat (DVF); in a first fractionation step (DFR), fractionating the distilled vegetable fat (DVF) into a first higher melting point fraction (FHF) being rich in tri-stearate triglycerides (StStSt, where St=stearic acid) and di-stearate diglycerides (StSt) and a first lower melting point fraction (FLF); and in a second fractionation step, fractionating the first lower melting point fraction (FLF) into a second higher melting point fraction (SHF) being rich in 1,3-distearyl-2-oleyl-triglycerides (StOSt, where O=oleic acid), and a second lower melting point fraction (SLF) being rich in 1-stearyl-2,3-dioleyl-triglycerides (StOO) and trioleate-triglycerides (OOO) in a solvent fractionation process (SF
