Abstract
Novel compositions containing conjugated linoleic acids are efficacious as animal feed additives and human dietary supplements. Linoleic acid is converted to its conjugated forms in which the resulting composition is low in certain unusual isomers compared to conventional conjugated linoleic products.
Claims18
A process for producing low impurity biologically active conjugated linoleic acid alkylester comprising
- providing a linoleic acid containing seed oil, an alcohol, and an alkali catalyst compatible with a nonaqueous medium;
- treating said linoleic acid containing seed oil to form alkylesters of said linoleic acid;
- forming a blended reaction mix with said alkylesters and an alkali catalyst compatible with a nonaqueous medium;
- isomerizing said alkylesters to form conjugated linoleic acid alkylesters;
- and
- neutralizing said blended reaction mix.
A process for producing a food product containing a low impurity biologically active conjugated linoleic acid alkylester comprising
- providing a linoleic acid containing seed oil and an alcohol;
- treating said linoleic acid containing seed oil to form alkylesters of said linoleic acid;
- forming a blended reaction mix with said alkylesters and an alcoholate catalyst;
- isomerizing said alkylesters to form conjugated linoleic acid alkylesters;
- and
- combining said conjugated linoleic alkylesters with a human or animal food product.
A process for producing a conjugated linoleic acid alkylester for use in domestic animal feed, food ingredients, or human dietary supplements comprising
- providing a linoleic acid alkylester having phosphatidyl residue content of less than about 0.5 percent;
- treating with an alkali alcoholate at low temperature in the presence of a monohydric low molecular weight alcohol to cause isomerization of at least 50 percent of the linoleic acid alkyl ester to conjugated linoleic alkylester at low temperature;
- and
- neutralizing the isomerized mixture.
