The invention is directed to CLA-rich vegetable oil production from linoleic rich oils by heterogeneous catalysis. The process produces conjugated PUFA in triglyceride form, preferably at least 20% CLA-rich, by isomerization of a non-conjugated PUFA in vegetable oils using a heterogeneous transition metal catalyst promoted by an organic acid and/or thiol-containing compound. The heterogeneous catalysis isomerization process can use steam/vacuum distillation, hydrogenation unit and/or deodorization to produce CLA-rich soy oil. After processing, any catalyst residue may be removed by filtration, beaching, deodorizing, adsorbents or centrifugation to obtain high quality, CLA-rich oils.

Conjugated linoleic acid rich vegetable oil production using heterogeneous catalysis

The invention is generally directed to conjugated linoleic acid (CLA)-rich vegetable oil production from linoleic rich oils by heterogeneous catalysis. A heterogeneous catalytic vacuum distillation process is used under high temperature conditions to isomerize linoleic acid in triacylglyceride vegetable oils to CLA to produce CLA-rich oils. After processing, the catalyst may be removed by filtration or centrifugation to obtain high quality, CLA-rich oils. The CLA-rich oils may then serve as a potent and bioactive nutraceutical and can be incorporated into various food products, such as a CLA-rich dressing, margarine or chips.

Conjugated linoleic acid rich vegetable oil production from linoleic rich oils by heterogeneous catalysis

This invention relates generally to trans-,trans-conjugated linoleic acid compositions and use thereof, and in particular to trans-,trans-conjugated linoleic acid produced from photoisomerization of soy oil in the presence of an antioxidant, and used in pharmaceutical, nutraceutical and human and animal food compositions for improved health. The invention also relates generally to a method for treatment and prevention of health-related disorders of obesity by administration of pharmaceutical, nutraceutical and/or food compositions containing and/or prepared from trans-,trans-conjugated linoleic acid-rich soy oil.
