    Abstract: A double layered polymer capsule is provided to ensure excellent stabilization effect on oxidation-sensitive materials and to prevent the denaturation of an active material from an outside harmful environment. A double layered polymer capsule comprises a core consisting of carotenoid, a cationic polymer layer that surrounds the core, and an anionic polymer layer coated on the surface of a cationic polymer capsule. A method for manufacturing the double layered polymer capsule comprises (i) copolymerizing a monomer having a cationic functional group and a monomer having a hydrophobic group to obtain an cationic polymer; (ii) dissolving the cationic polymer and carotenoid in organic solvent to prepare emulsion, and evaporating the organic solvent to obtain the cationic polymer capsule supported with carotenoid; (iii) copolymerizing a monomer having an anionic functional group to obtain an anionic polymer; and (iv) applying the anionic polymer to the surface of the cationic polymer capsule.

    Abstract translation: 提供双层聚合物胶囊以确保对氧化敏感材料的优异的稳定化作用,并防止活性物质从外部有害环境变性。 双层聚合物胶囊包括由类胡萝卜素,包围核心的阳离子聚合物层和涂覆在阳离子聚合物胶囊表面上的阴离子聚合物层组成的核心。 制造双层聚合物胶囊的方法包括(i)使具有阳离子官能团的单体和具有疏水基团的单体共聚以获得阳离子聚合物; (ii)将阳离子聚合物和类胡萝卜素溶解在有机溶剂中以制备乳液,并蒸发有机溶剂以获得由类胡萝卜素支持的阳离子聚合物胶囊; (iii)使具有阴离子官能团的单体共聚得到阴离子聚合物; 和(iv)将阴离子聚合物施加到阳离子聚合物胶囊的表面。
