摘要：
A method of highly efficient extraction of fish oil is provided, which includes homogenization of fish material with hexane using a high shear homogenizer. High shear homogenizer ground the fish material into tiny particles, which helped disperse the water into the hexane phase, and increased the contact between hexane and the non-polar fish oil, and simultaneous extraction of fish oil. After extraction, the mixture containing fish oil and hexane was recovered by centrifugation and transferred to a rotary evaporator to remove the hexane and recover the fish oil. This extraction method operated at a low temperature for a short period that preventing n-3 polyunsaturated fatty acids decomposition, such as eicosapentaenoic acid (EPA； C20:5) and docosahexaenoic acid (DHA； C22:6), and increased the extraction yield of fish oil.本發明揭露一種高效萃取魚油的方法，步驟包括將魚原料與正己烷置於高剪切均質機中同時進行魚原料均質與魚油萃取處理，高剪切均質可將魚原料研磨成細小顆粒，分散魚原料中的水分進入己烷溶劑，增加魚油與己烷的接觸，並同步萃取魚油，萃取後含魚油的正己烷溶液以離心方式回收，再以減壓濃縮機中去除正己烷，以獲得魚油。此方法可於低溫快速萃取魚原料中的油脂，避免高溫下魚油中多元不飽和脂肪酸如二十二碳六烯酸、二十碳五烯酸的破壞，並提高魚油的萃取率。
