Abstract
The present invention relates to a process for producing ethyl esters of polyunsaturated fatty acids, comprising transesterifying triacylglycerols in extracted plant lipid.
Claims18
A process for producing extracted lipid, comprising the steps of:
- a) obtaining Brassica napus or Camelina sativa seed comprising extractable lipid having a total fatty acid content, the lipid comprising fatty acids esterified as triacylglycerols (TAG), the fatty acids comprising oleic acid, palmitic acid, linoleic acid (LA), γ-linolenic acid (GLA), α-linolenic acid (ALA), stearidonic acid (SDA), docosapentaenoic acid (DPA), docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and eicosatetraenoic acid (ETA), wherein at least 70% by weight of the DHA which is esterified in the form of TAG is esterified at the sn-1 or sn-3 position of TAG, and
- b) extracting lipid from the seed.
