Abstract (en)
[origin: WO2021191385A1] The invention relates to a method of fractionating fatty acids having two different carbons by double-pass molecular distillation, in particular fractionating between eicosapentaenoic acid and docosahexaenoic acid, and compositions of oil originating from micro-organisms enriched with eicosapentaenoic acid or docosahexaenoic acid produced by such a method. To this end, the invention relates to a method of fractionating fatty acids having two different carbons by molecular distillation, in particular fractionating between eicosapentaenoic acid and docosahexaenoic acid, characterised in that the method comprises: (i) a step of reaction between an oil originating from micro-organisms, which comprises omega-3 polyunsaturated fatty acids in the form of triglycerides, and an alcohol in the presence of a chemical or enzyme catalyst, (ii) a first step of molecular distillation, in a high vacuum, of the oil obtained in step (i) in a wiped film evaporator coupled to a rectification column comprising at least seven theoretical plates, and collection of a first residue and a first distillate, (iii) a second step of molecular distillation, in a high vacuum, of the residue collected in step (ii) in the wiped film evaporator coupled to the rectification column comprising at least seven theoretical plates, and collection of a second residue and a second distillate.
