Disclosed is a process for reducing the amount of sterol in a sterol-containing microbial oil composition, including distilling, under short path distillation conditions, a sterol-containing microbial oil wherein said distillation produces a distillate fraction containing the sterol and a triacylglycerol-containing fraction having a reduced amount of the sterol when compared to the amount of sterol in the sterol-containing microbial oil composition that has not been subjected to short path distillation.

Purification of triglyceride oil from microbial sources using short path distillation

Methods are provided for pelletizing a microbial biomass, extracting a refined lipid composition from the pelletized biomass under supercritical conditions and distilling the refined lipid composition, at least once under short path distillation conditions, to obtain a lipid-containing fraction. Also disclosed are methods of making lipid-containing oil concentrates therefrom, by transesterifying and enriching the lipid-containing fraction.
