    • Disclosed is a method for reducing the sterol, for example cholesterol, content of sterol-containing substances such as fats and oils. The method provides an efficient and cost effective process based on the affinity of cholesterol and other sterols for amphipathic molecules that form hydrophobic, fluid bilayers, such as phospholipid bilayers. Aggregates of amphipathic molecules are contacted with, for example, a sterol-containing fat or oil in an aqueous environment and then mixed. Following adequate mixing, the sterol-reduced fat or oil is separated from the aqueous separation mixture. Alternatively, the correspondingly sterol-enriched fraction also may be isolated from the aqueous separation mixture.
    • 公开了一种降低固醇的方法,例如胆固醇,含甾醇的物质如脂肪和油的含量。 该方法基于胆固醇和其他固醇对形成疏水性,流体双层如磷脂双层的两亲分子的亲和力提供了有效且成本有效的方法。 两性分子的聚集体与水性环境中的例如含甾醇的脂肪或油接触,然后混合。 在充分混合后,将固醇还原的脂肪或油从水分离混合物中分离。 或者,相应的富含固醇的级分还可以从水分离混合物中分离出来。

    • Hydrogenated canola oils having improved oxidative stability are disclosed. These oils have relatively low levels of trans-fatty acids and saturated fatty acids, yet possess an oxidative stability of greater than 300 AOM hours. Such oils can be produced by hydrogenation of refined, bleached canola oil extracted from Brassicaceae seeds having elevated levels of oleic acid and reduced levels of polyunsaturated fatty acids. Brassica lines producing seeds having such fatty acid profiles are disclosed. Hydrogenated oils may be fractionated to obtain canola oils that are liquid at or below room temperature and have relatively low levels of trans-fatty acids and saturated fatty acids, yet have an oxidative stability of greater than 300 AOM hours.
    • 公开了具有改善的氧化稳定性的氢化卡诺拉油。 这些油具有相对低水平的反式脂肪酸和饱和脂肪酸,但具有大于300AOM小时的氧化稳定性。 这种油可以通过从具有升高的油酸水平和降低的多不饱和脂肪酸水平的甘蓝科种子提取的精制漂白的卡诺拉油的氢化来生产。 公开了生产具有这种脂肪酸分布的种子的芸苔属品系。 氢化油可以分馏以获得在室温或低于室温下为液体并具有相对低水平的反式脂肪酸和饱和脂肪酸的低芥酸菜子油,但具有大于300AOM小时的氧化稳定性。
