Claims17
A process for producing ethyl esters of polyunsaturated fatty acids, the process comprising transesterifying triacylglycerols in Brassica napus seedoil to thereby produce the ethyl esters, wherein the Brassica napus seedoil comprises fatty acids esterified in the form of triacylglycerols, the fatty acids 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),
- 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) palmitic acid is present at a level of between 2% and 16% of the total fatty acid content of the Brassica napus seedoil,
- ii) oleic acid is present at a level of between 1% and 60% of the total fatty acid content of the Brassica napus seedoil,
- iii) LA is present at a level of between 4% and 35% of the total fatty acid content of the Brassica napus seedoil,
- iv) GLA is present at a level of less than 4% of the total fatty acid content of the Brassica napus seedoil,
- v) ALA is present at a level of between 2% and 16% of the total fatty acid content of the Brassica napus seedoil,
- vi) the total saturated fatty acid content is between 4% and 25% of the total fatty acid content of the Brassica napus seedoil,
- vii) the ratio of the total ω6 fatty acid content to the total ω3 fatty acid content in the total fatty acid content of the Brassica napus seedoil is between 0.05 and 3.0,
- viii) myristic acid is present at a level of less than 2% of the total fatty acid content of the Brassica napus seedoil or is absent,
- ix) eicosatrienoic acid (ETrA) is present at a level of less than 4% of the total fatty acid content of the Brassica napus seedoil or is absent, and
- x) DHA is esterified in the form of triacylglycerols (TAG), wherein at least 70% of the DHA which is esterified in the form of TAG is esterified at the sn-1 or sn-3 position of the TAG,
- wherein the level or content percentages correspond to a percentage by weight.
