PROBLEM TO BE SOLVED: To provide a method for easily and simply producing an oil, which is scarcely oxidized and in which the fish smell is reduced, from shark liver.SOLUTION: An oil is dripped by heating the shark liver in a gas phase at 65 to 70°C. The dripped oil is captured in a saline solution or in a glycerol solution, and the oil is separated from the saline solution or the glycerol solution. Subsequently, the oil is brought sufficiently into contact with a desiccant of an inorganic salt composed of a strong acid and a strong base to remove moisture in the oil, and the desiccant is separated. The obtained oil is scarcely oxidized and the fish smell thereof is reduced.COPYRIGHT: (C)2013,JPO&INPIT【課題】サメ肝臓から、酸化しにくく、かつ魚臭の低減された油を、手軽に簡単に製造する方法。【解決手段】サメ肝臓を気相中において、65℃~70℃で加熱することにより、油を滴り落とす。この落ちた油を食塩水又はグリセリン溶液に捕集し、油を食塩水又はグリセリン溶液から分離する。次にその油に強酸と強塩基からなる無機塩の乾燥剤と十分接触させ、油の中の水分を除去し、この乾燥剤を分離する。得られた油は、酸化しにくく、かつ魚臭が低減されている。【選択図】なし
