Abstract
The present invention relates to a concentration- and purification method for compositions containing phytanic acid and/or derivatives thereof besides other fatty acids and/or their derivatives, preferably besides polyunsaturated fatty acids and/or their derivatives, such as esters or salts. With the fractionation process the phytanic acid (derivative) can become concentrated and the fatty acid mixture, preferably PUFA-mixture, can be purified from this particular component.
Claims30
A process for fractionation of chromatographic feed material comprising fatty acids and/or derivatives thereof including phytanic acid and/or its derivatives said process comprises subjecting said chromatographic feed material to column chromatography using a liquid or a supercritical fluid as an eluent and collecting a plurality of eluate fractions, one or more of which contain increased amounts of phytanic acid and/or of its derivatives, and one or more of which contain reduced amounts of phytanic acid and/or its derivatives.
A composition of matter comprising at least 60% by weight of polyunsaturated fatty acids and/or their derivatives and between 0 and 100 ppm of phytanic acid and/or of its derivatives.
A composition comprising polyunsaturated fatty acids and/or their salts and/or their alkyl esters and comprising between 3000 ppm and 100% by weight of phytanic acid and/or its salts and/or its alkyl esters.
