Abstract
There is provided a vegetable-based lipid composition comprising high levels of at least three different long-chain polyunsaturated fatty acids (typically as fatty acid esters). The compositions contain DHA as the principal long-chain polyunsaturated fatty acid. The composition is obtainable from a single source by conventional processing methods, and has improved stability properties.
Claims17
A vegetable-based lipid composition comprising:
- (i) docosahexaenoic acid (22:6n-3) (DHA) in an amount of from 50% to 85% by weight of the total fatty acid content of the composition;
- (ii) a second polyunsaturated fatty acid in an amount of from 10% to 90% by weight of the DHA;
- and
- (iii) a third polyunsaturated fatty acid in an amount of from 10% to 70% by weight of the second polyunsaturated fatty acid;
- wherein the total amount of all other fatty acids in the composition is up to 20% by weight of the total fatty acid content of the composition, wherein the second or third polyunsaturated fatty acid is eicosatetraenoic acid (20:4n-3) (ETA), wherein each of the docosahexaenoic acid, and the second and third polyunsaturated fatty acids is independently provided in the form of a fatty acid, a fatty acid salt, a fatty acid ester or a salt of a fatty acid ester;
- wherein the amount of eicosapentaenoic acid (EPA) in the composition is less than 10% by weight of the amount of DHA, wherein the ratio of omega-3 fatty acids to omega-6 fatty acids in the composition is at least 10:1, wherein the composition contains less than 0.5% palmitic acid (C16:0) by weight of the total fatty acid in the composition;
- and wherein the lipids present in the composition are obtained from plant sources.
