  • Patent number: 5965755
    Abstract: A variety of Brassica napus, designated AG019, and varieties essentially derived therefrom, having oil which combines oxidative stability sufficient for industrial applications with a desirable dietary fatty acid profile. Plants, seeds, tissue cultures, and plants regenerated from tissue cultures. Oil having an oleic acid content of from about 71.4% to about 77.4%, a linolenic acid content of no more than about 3%, an oleic:linolenic acid ratio value of at least about 34.0, and an (oleic+linoleic)/linolenic acid ratio value of at least about 41.2. The oil has substantially improved oxidative stability, relatively to normal rapeseed oil, when both are treated with antioxidant.

  • Patent number: 5621125
    Abstract: A triglyceride oil containing a membrane lipid in a concentration effective for crystallization modification the membrane lipid having a formula:C.sub.13 H.sub.27 --CH.dbd.CH--CH(OH)--CH(NHCOA.sub.2)--CH2--OA.sub.4,wherein C.sub.13 H.sub.27 -- is an unbranched alkyl chain, A.sub.2 is an unbranched C.sub.23 H.sub.47 -- hydrocarbon chain, and A.sub.4 is a sugar moiety selected from the group consisting o a monosaccharide residue, a disaccharide residue or an oligosaccharide residue, including glucose, fructose, galactose, saccharose, lactose and maltose. Said membrane is utilized to separate solid fatty materials from triglyceride oils by heating the oil in an inert solvent until a substantial amount of the solid material is no longer present, adding the membrane lipid as the crystallization modifying substance, cooling the oil to crystallize a solid stearin phase in combination with a liquid olein phase, and recovering the stearin phase by separating it from the olein phase.

  • Patent number: 5155244
    Abstract: A method of solubilizing a first compound in a second medium where the first compound has a limited solubility in the second medium. In particular, the method comprises reacting the first compound with the second medium. By this reaction, a product is formed whereby an active component of the first compound is covalently incorporated into the second medium.The first compound and second medium each contain at least one reactive group which will react with a reactive group of the other. In addition, the first compound comprises at least one antioxidant which will be covalently bonded to and thus effectively solubilized in the second medium by the reaction.The second medium comprises glyceride derivatives, silicones, fluorocarbons and alkoxylates containing reactive groups such as hydroxy, amino, carboxyl, ester, or amides.
