Oil containing one or more long chain polyunsaturated fatty acids from biomass, process for preparing, food, nutritional composition, cosmetic or pharmaceutical composition containing the same

摘要

A stable oil forming part of alimentary, nutritional, pharmaceutical or cosmetic products containing one or more long chain polyunsaturated fatty acids deriving from a biomass in the form of triacylglycerols, which serves both to transfer the fatty acids from the biomass and to act as a support for them in the product. The oil incorporates at least 60 wt.% of the fatty acids and less than 10 wt.% of the phosphorus present in the biomass. Independent claims are included for: (1) preparation of the oil by contacting a support oil with a biomass arising from the culture of a microorganism containing a long chain polyunsaturated acid or acids in such a way as to transfer the fatty acids onto the support, separating out the oil by pressing the biomass, filtering and deodorizing under gentle conditions; (2) food containing the oil; (3) infant food containing the oil; (4) nutritional composition containing the oil; (5) cosmetic composition in dry or emulsion form containing the oil; (6) animal feed containing the oil; and (7) foodstuff for animal feed containing the residue of the biomass on completion of the procedure.
