  • Publication number: 20170267945
    Abstract: A process for the production of a composition comprising 1,3-dioleoyl-2-palmitoyl glyceride (OPO) comprises: providing one or more palm oil stearin fractions comprising tripalmitoyl glyceride and having an iodine value between about 18 and about 40; interesterifying the one or more palm oil stearin fractions to form a randomly interesterified palm oil stearin; subjecting the randomly interesterified palm oil stearin to enzymic transesterification with oleic acid or a non-glyceride ester thereof using an enzyme having selectivity for the 1- and 3-positions of a glyceride; and separating palmitic acid or palmitic non-glyceride esters from the product obtained in (iii) to form a composition comprising OPO glyceride.

  • Patent number: 7910757
    Abstract: A process for the preparation of a material comprising conjugated isomers of a polyunsaturated fatty acid comprises: treating a first fatty acid mixture comprising saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids in the presence of ethanol to form (i) a solid fraction and (ii) a liquid fraction comprising a second fatty acid mixture, wherein the second fatty acid mixture has a higher molar ratio of total polyunsaturated fatty acids to total saturated and monounsaturated fatty acids than the first fatty acid mixture; separating the solid fraction and the liquid fraction; and subjecting the second fatty acid mixture or a derivative or reaction product thereof to treatment with a base in the presence of a solvent, to form conjugated isomers of at least some of the polyunsaturated fatty acids.
