Abstract
The present invention relates to extracted plant lipid, comprising fatty acids in an esterified form.
Claims29
Extracted plant lipid, whose total fatty acid content comprises
- (a) a total monounsaturated fatty acid content which comprises oleic acid,
- (b) a total saturated fatty acid content which comprises palmitic acid and, if present, myristic acid (C14:0),
- (c) a total ω6 fatty acid content which comprises linoleic acid (LA),
- (d) a total ω3 fatty acid content which comprises α-linolenic acid (ALA), docosahexaenoic acid (DHA) and one or more of stearidonic acid (SDA), eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and eicosatetraenoic acid (ETA),
- (e) less than 6% myristic acid (C14:0), and
- (f) less than 4% eicosatrienoic acid (ETrA),
- wherein
- (i) a level of DHA between 7% and 20% is present in the total fatty acid content of the extracted plant lipid, wherein at least 70% of the DHA is esterified at the sn-1 or sn-3 position of triacylglycerol (TAG),
- (ii) a level of palmitic acid between 2% and 16% is present in the total fatty acid content of the extracted plant lipid,
- (iii) a level of oleic acid between 1% and 60% is present in the total fatty acid content of the extracted plant lipid,
- (iv) a level of linoleic acid (LA) between 4% and 35% is present in the total fatty acid content of the extracted plant lipid,
- (v) a level of α-linolenic acid (ALA) between 4% and 40% is present in the total fatty acid content of the extracted plant lipid,
- (vi) the total saturated fatty acid content of the extracted plant lipid is between 4% and 25% of the total fatty acid content,
- (vii) the ratio of the total ω6 fatty acid content to the total ω3 fatty acid content of the extracted plant lipid is between 0.1 and 3.0, and
- (viii) at least 70% of the total fatty acid content of the extracted plant lipid is esterified in the form of TAG.
