  • Process for reducing the polyunsaturates content in mixtures of unsaturated fatty acids and/or fatty acid esters
    Patent number: 4327030
    Abstract: A process for reducing the amount of polyunsaturated fatty acid and/or polyunsaturated fatty acid ester present in admixture with monounsaturated fatty acid and/or monounsaturated fatty acid ester is provided which comprises heating the admixture of fatty acids and/or fatty acid esters in the presence of a polymerization initiating amount of at least one organic peroxide at a temperature and for a period of time which is sufficient to effect the selective polymerization of a substantial amount of polyunsaturated fatty acid and/or polyunsaturated fatty acid ester present in said admixture, and thereafter separating the polymerized polyunsaturated fatty acid and/or polyunsaturated fatty acid ester from said admixture. The aforedescribed process is especially useful for reducing the amount of linoleic acid present in high oleic acid-content vegetable oils.
