Abstract
Stable oil containing long-chain polyunsaturated essential fatty acids (LC-PUFAs) in the form of triacylglycerols, in particular arachidonic acid (ARA), dihomogammalinolenic acid (DHGLA), docosahexaenoic acid (DHA) or eicosapentaenoic acid (EPA). Such an oil may be prepared by bringing a carrier oil into contact with a biomass obtained from the culture of a microorganism, in particular a fungus or a microalga containing the acids ARA, DHGLA, DHA or EPA. These oils can be incorporated into the composition of a foodstuff, of a cosmetic or pharmaceutical product.

1-19. (canceled)
A stable oil for incorporation in a food, nutritional, pharmaceutical or cosmetic product, the stable oil made by a process comprising combining a carrier oil and one or more long-chain polyunsaturated fatty acids from a biomass obtained from the culture of a microorganism, in the form of triacylglycerols, wherein the long-chain polyunsaturated fatty acids are incorporated into the carrier oil such that at least 60% by weight of the long-chain polyunsaturated fatty acids present in the biomass are present in the carrier oil but that less than 10% of phosphorus that is present in the biomass is present in the carrier oil, so that the carrier oil does not require purification prior to use and wherein the stable oil contains no more than 10% by weight of the long-chain polyunsaturated fatty acids in the form of triacylglycerols.
A process for preparing a stable oil for incorporation into a composition of a food, nutritional, pharmaceutical or cosmetic product, the process comprising bringing a carrier oil into contact with a biomass obtained from the culture of a microorganism containing one or more long-chain polyunsaturated fatty acids, so as to transfer the long-chain polyunsaturated fatty acid(s) in the form of triacylglycerols to the carrier oil and form a biomass residue, separating the carrier oil containing the fatty acid(s) from the biomass residue, and then deodorizing the separated carrier oil to obtain the stable oil, wherein the stable oil contains no more than 10% by weight of the long-chain polyunsaturated fatty acids in the form of triacylglycerols.
