Abstract
The present invention relates to the manufacture of conjugated linoleic acid, and in particular, to dietary supplements, feeds and food products containing conjugated linoleic acid. Accordingly, processes for producing conjugated linoleic acid of high purity and acid value are disclosed. These processes utilize alcoholate catalysts and esters of sunflower oil, safflower oil, or corn oil as the source of linoleic acid. The esters of conjugated linoleic acid produced by the process can be used in animal feeds and in food products suitable for human consumption. Furthermore, the esters can be converted into free fatty acids or incorporated into triglycerides.
Claims16
A method for producing conjugated linoleic acid with a high acid value comprising:
- a) providing:
- i) a composition comprising esters of linoleic acid;
- and
- ii) an alcoholate catalyst;
- b) treating said composition comprising esters of linoleic acid with said alcoholate catalyst to produce a conjugated linoleic acid ester composition;
- c) treating said conjugated linoleic acid ester composition with alkali to produce a saponified conjugated linoleic acid composition;
- and
- d) treating said saponified conjugated linoleic acid composition with a mild acid wash to produce a free conjugated fatty acid composition containing at least about 0.5% esters of conjugated linoleic acids.
