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.
A process for producing conjugated linoleic acid-rich oil, said process comprising the steps of:
The process of claim 44 wherein said transition metal is selected from the group consisting of ruthenium, rhodium, molybdenum, palladium, gold, silver, copper, iron, manganese or nickel.
A process for enriching a linoleic acid-rich vegetable oil, said process comprising the step of distilling said linoleic acid-rich vegetable oil in the presence of a transition metal catalyst to produce a conjugated linoleic acid-rich oil.
The process of claim 45 wherein said metal catalyst is selected from the group consisting of ruthenium, rhodium, molybdenum, palladium, gold, silver, copper, iron, manganese or nickel.
