    • Disclosed is a method for preparing a CLA-enriched structured lipid by a transesterification of medium chain triglyceride (MCT) with ester or free fatty acid form of CLA using lipases, and use of the same. It has been known that CLA mainly exists in an acid form, and has various beneficial biological activities, but rapid oxidation property during storage. And also, animal fat or plant oil, widely ingested by animals or humans, is naturally produced as an acylglycerol form containing various fatty acids. The CLA-containing structured lipid is manufactured by mixing free or ester form of CLA with acylglyceride at a molar ratio of 1:1null1:5, adding immobilized lipase of 2.2null20% by weight of CLA and acylglyceride to the mixture with a solvent, and incubating at 35null75null C. for 1-36 hours. The CLA-containing structured lipid is a natural TG form and contains a high content of CLA, characterized by at least 15% content of CLA in total fatty acid composition, and at least 5% of CLA at sn-2 position. Accordingly, with the CLA-enriched MCT being administrated, it can efficiently provide biological activities of CLA, such as inhibition of carcinogenesis and reduction of fat accumulation in a body, as well as rapidly supply calories, an innate nutritional property of MCT.
    • 公开了一种通过中链甘油三酯(MCT)与脂肪酶的酯或游离脂肪酸形式的酯交换制备富含CLA的结构化脂质的方法,并使用该方法。 已知CLA主要以酸的形式存在,并且具有各种有益的生物活性,但在储存期间具有快速的氧化性能。 而且,动物或人类广泛摄取的动物脂肪或植物油天然产生为含有各种脂肪酸的酰基甘油形式。 通过将游离或酯形式的CLA与酰基甘油酯以1:1〜1:5的摩尔比混合制造,通过将具有2.2〜20重量%的CLA和酰基甘油酯的固定化脂肪酶加入到混合物中来制备含CLA的结构化脂质 溶剂,并在35〜75℃下孵育1-36小时。 含CLA的结构化脂质是天然的TG形式,并且含有高含量的CLA,其特征在于总脂肪酸组成中至少15%的CLA含量,以及sn-2位置的至少5%的CLA。 因此,通过施用富CLA的MCT,可以有效地提供CLA的生物活性,例如抑制癌发生和减少体内脂肪的积累,以及快速提供卡路里,MCT的先天营养特性。

    • The invention is a method for recovering azelaic acid from a mixed oxidation product by prepurifying the azelaic acid and introducing the prepurified azelaic acid into the central portion of a dual countercurrent extraction column operated at an elevated temperature and introducing an aqueous phase into the top of the extraction column and a water immiscible solvent for the monocarboxylic acids in the prepurified azelaic acid into the bottom portion of the extraction column and recovering the purified azelaic acid from the aqueous phase. The azelaic acid can be recovered from the aqueous phase by drying the aqueous phase and separating a low boiling fraction and a high boiling fraction from the azelaic acid product by distillation.
