In this process, raw algae is dewatered to yield algal oil.  Algal oil gets degummed, typically via washing with acid, to removing polar lipids and metals.  Degummed algal oil is then transesterified and purified to yield a mixture of omega−7 esters and eicosapentaenoic acids, which can be hydrodeoxygenated to form 1002: 438:

consumed by a cow is correlated with a significant decrease in the omega−7 fatty acid content of the cow's milk.
