Abstract
Compositions and methods of using conjugated linoleic acid preparations enriched for the t10,c12 and c9,t11 isomers are disclosed. It is found that preparations of conjugated linoleic acid containing a ratio of t10,c12 to c9,t11 of about greater than 1.2:1 are desirable for a wide variety of nutritional, therapeutic and pharmacologic uses.
Claims28
A conjugated linoleic acid composition comprising:
- a mixture of free fatty acid conjugated linoleic acid isomers, said mixture containing at least approximately 80% t10,c12 octadecadienoic acid.
A conjugated linoleic acid composition comprising:
- a mixture of free fatty acid conjugated linoleic acid isomers, said mixture containing at least approximately 92% t10,c12 octadecadienoic acid.
An acylglycerol composition comprising a plurality of acylglycerol molecules of the structure:
- 2
- wherein R1, R2, and R3 are selected from the group consisting of a hydroxyl group and an octadecadienoic acid, said composition characterized in containing at least approximately 80% t10,c12 octadecadienoic acid at positions R1, R2, and R3.
An acylglycerol composition comprising a plurality of acylglycerol molecules of the structure:
- 3
- wherein R1, R2, and R3 are selected from the group consisting of a hydroxyl group and an octadecadienoic acid, said composition characterized in containing at least approximately 92% t10,c12 octadecadienoic acid at positions RI, R., and R3.
A conjugated linoleic acid composition produced by the process comprising:
- a) providing a commodity seed oil and a method for treating said seed oil;
- and
- b) treating said seed oil under conditions such that a preparation comprising t10,c12 octadecadienoic acid is produced, wherein said preparation is at least approximately 80% t10,c12 CLA.
A conjugated linoleic acid composition produced by the process comprising:
- a) providing a commodity seed oil;
- and
- b) forming a mixture of fatty acid alkylesters from said seed oil;
- c) conjugating said fatty acid alkylesters to form conjugated fatty acid alkylesters, said conjugated fatty acid alkylesters characterized in comprising t10,c12 alkylester;
- d) diluting said conjugated fatty acid alkyl esters in a solvent to form a solution;
- and
- e) precipitating t10,c12 alkylester from said solution.
A conjugated linoleic acid composition comprising:
- a mixture of alkylesters of conjugated linoleic acid, said mixture containing at least approximately 80% t10,c12 alkylester.
A conjugated linoleic acid composition comprising:
- a mixture of alkylesters of conjugated linoleic acid, said mixture containing at least approximately 92% t10,c12 alkylester.
A conjugated linoleic acid composition comprising:
- about 30-60% c9,t11 octadecadienoic acid and about 15-30% t10,c12 octadecadienoic acid, so that the ratio of c9,t11 octadecadienoic acid to t10,c12 octadecadienoic acid is about 2:1.
