A method for producing a composition comprising conjugated linoleic acid in an amount of at least 55% by weight, comprises: (i) providing a liquid mixture comprising, as the free acids, from 50 to 95% by weight conjugated linoleic acid and at least 5% by weight of saturated C12-C22 fatty acids; (ii) cooling the liquid mixture to a temperature at which at least a part of the saturated C12-C22 fatty acids precipitate from the mixture as a solid; and (iii) separating the solid from the liquid, wherein the liquid obtained in (iii) comprises conjugated linoleic acid in an amount of at least 55% by weight.

Method for producing conjugated linoleic acid

A process for producing a conjugated di- or poly-unsaturated fatty acid having from 12 to 24 carbon atoms, or a salt or ester thereof, comprises: reacting a non-conjugated free fatty acid, or a salt or ester thereof, with a base in the presence of an alcoholic solvent comprising ethanol; and separating the conjugated fatty acid from the reaction mixture, wherein the separation of the conjugated fatty acid from the reaction mixture comprises contacting the reaction mixture with an aqueous salt solution and removing a liquid phase which comprises the salt solution and at least a part of the solvent from a solid phase which comprises a salt of the conjugated fatty acid.

Process for producing a conjugated unsaturated fatty acid

A process for the preparation of a composition comprising the cis9, trans11 and trans10, cis12 isomers of conjugated linoleic acid (CLA) comprises: providing a mixture comprising cis9, trans11 and trans10, cis12 isomers of conjugated linoleic acid (CLA) in which one of the cis9, trans11 and trans10, cis12 isomers is present in a first weight ratio X of at least 1.3:1 with respect to the other isomer; and subjecting the mixture to crystallization to form a composition comprising the cis9, trans11 and trans10, cis12 isomers in which one of the cis9, trans11 and trans10, cis12 isomers is present at a second weight ratio Y with respect to the other isomer, wherein Y is greater than X.
