Abstract
The present invention relates to a process for producing ethyl esters of polyunsaturated fatty acids, comprising transesterifying triacylglycerols in extracted plant lipid.
Claims27
Oil extracted from seeds which are Brassica napus, Camelina sativa or Arabidopsis thaliana seeds, wherein the oil has a total fatty acid content comprising
- a) a total monounsaturated fatty acid content which comprises oleic acid,
- b) a total saturated fatty acid content which comprises palmitic acid or palmitic acid and myristic acid (C14:0),
- c) a total ω6 fatty acid content which comprises linoleic acid (LA) and γ-linolenic acid (GLA), and, if present, arachidonic acid (ARA), and
- d) a total ω3 fatty acid content which comprises α-linolenic acid (ALA), docosahexaenoic acid (DHA), stearidonic acid (SDA), eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and eicosatetraenoic acid (ETA),
- wherein
- i) EPA, DPA and DHA, and optionally ARA, are each present at a level in the total fatty acid content, each level being expressed as a percentage of the total fatty acid content, whereby the sum total of the levels of ARA, EPA, DPA and DHA in the extracted oil is between 7% and 25% of the total fatty acid content,
- ii) eicosatrienoic acid (ETrA) is present in the extracted oil at a level of between 0.05% and 3% of the total fatty acid content,
- iii) palmitic acid is present in the extracted oil at a level of between 2% and 16% of the total fatty acid content,
- iv) oleic acid is present in the extracted oil at a level of between 1% and 30% of the total fatty acid content,
- v) LA is present in the extracted oil at a level of between 4% and 35% of the total fatty acid content,
- vi) GLA is present in the extracted oil at a level of less than 4% of the total fatty acid content,
- vii) ALA is present in the extracted oil at a level of between 4% and 40% of the total fatty acid content,
- viii) the total saturated fatty acid content of the extracted oil is between 4% and 25% of the total fatty acid content,
- ix) the ratio of the total ω6 fatty acid content to the total ω3 fatty acid content of the extracted oil is between 0.1 and 3.0, and
- x) myristic acid, if present, is present at a level of less than 1% of the total fatty acid content.
