A process to manufacture conjugated linoleic acid (CLA)-containing materials including conjugated linoleic salts and acids that are enriched in desirable cis-9, trans-11- and trans-10, cis-12-CLA isomers and are low in certain undesirable isomers. The process generally entails isomerization of an alkyl ester of a linoleic acid-containing material, such as sunflower oil or safflower oil, to effectuate conjugation of the double bonds, followed by saponification of the resultant CLA-containing fatty acid ester to produce a CLA-containing fatty acid salt, optionally followed by neutralization of the CLA-containing fatty acid salt with an acid source to produce a CLA-containing fatty acid.

L'invention concerne un procédé de fabrication de matériaux contenant de l'acide linoléique conjugué (CLA), y compris des sels et acides linoléiques conjugués qui sont enrichis en isomères cis-9, trans-11 et trans-10, cis-12-CLA recherchés et qui sont pauvres en certains isomères indésirables. Ledit procédé porte d'ordinaire sur l'isomérisation d'un ester alkyle d'un matériau contenant de l'acide linoléique, tel que l'huile de tournesol ou l'huile de carthame, pour effectuer la conjugaison des doubles liaisons, puis la saponification de l'ester d'acide gras contenant CLA résultant pour produire un sel d'acide gras contenant CLA, et éventuellement la neutralisation du sel d'acide gras contenant CLA avec une source d'acide afin de produire un acide gras contenant CLA.
