Title:

MANUFACTURE OF CONJUGATED LINOLEIC SALTS AND ACIDS

Document Type and Number:

WIPO Patent Application WO2004101719

Kind Code:

A3

Abstract:

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.
