Provided is a method for producing SOS hard butter containing at least 85 w/w% of 1,3-distearoyl-2-oleoylglycerol (SOS) among triglycerides by means of the solvent fractionation method, comprising the steps of: producing a lipid solution by using a solvent to dissolve a lipid starting material obtained via an enzymatic ester-exchange reaction crystallising out and removing a high-melting-point fraction by maintaining the lipid solution at between 10 and 25°C and crystallising out and collecting a mid-melting-point fraction by maintaining the lipid solution, from which the high-melting-point fraction has been removed, at between 0 and 15°C.Linvention porte sur un procédé qui permet de produire, par fractionnement par solvant, du beurre dur de type SOS contenant au moins 85% en poids de 1,3-distéaroyl-2-oléoylglycérol (SOS) parmi des triglycérides, lequel procédé consiste à : produire une solution lipidique en utilisant un solvant pour dissoudre une matière première lipidique obtenue par une réaction enzymatique déchange dester cristalliser et éliminer une fraction à point de fusion élevé en maintenant la solution lipidique à une température comprise entre 10 et 25°C et cristalliser et recueillir une fraction à point de fusion moyen en maintenant à une température comprise entre 0 et 15°C la solution lipidique dont on a éliminé la fraction à point de fusion élevé.본 발명은 효소 에스테르 교환반응을 통해 얻은 원료 유지를 용제에 용해시켜 유지 용액을 제조하는 단계 상기 유지 용액을 10 내지 25℃로 유지하여 고융점 분획을 결정화하여 제거하는 단계 및 상기 고융점 분획이 제거된 유지 용액을 0 내지 15 ℃로 유지하여 중융점 분획을 결정화하여 수득하는 단계를 포함하는, 용제분별법에 의해 트리글리세라이드 중 1,3-디스테아로일-2-올레오일글리세린(SOS)를 85 w/w% 이상 함유하는 SOS 하드버터를 제조하는 방법을 제공한다.
