The present invention relates to lipid comprising docosapentaenoic acid and/or docosahexaenoic acid wherein the docosapentaenoic acid and/or docosahexaenoic acid may be preferentially esterified at the sn-2 position of triacylglycerol, and processes for producing and using the lipid.

Provided are: a composition containing 96-99 area % of eicosapentaenoic acid alkyl ester, the composition having an arachidonic acid alkyl ester content of 0.7 area % or less, and an eicosapentaenoic-acid-alkyl-ester mono-trans isomer content of 2.5 area % or less; and a method for producing a composition containing a high concentration of eicosapentaenoic acid alkyl ester, the method including performing precision distillation on a composition containing eicosapentaenoic acid alkyl ester, obtained by alkyl esterification of a raw material oil containing eicosapentaenoic acid, under a vacuum of 0.2 Torr or lower and a temperature of 190 C. or lower in the entire column, and performing a concentration treatment on the precision-distilled composition using chromatography.

The present invention relates to a process for increasing the oxidative stability of short path evaporated oils. The process comprises the step of adding to the short-path evaporated-treated oil at least one anti-oxidant while the short-path evaporated-treated oil has a peroxide value of below or equal to 1.5 milli-equivalent peroxide/kg. The at least one anti-oxidant is preferably added at a temperature above the melting point of the short-path evaporated-treated oil.
