    • Disclosed is a method for manufacturing refined fish oil by introducing a novel process into a phospholipid-deprived fish oil which is obtained by mixing fish oil with water and a monosodium glutamate (MSG) by-product with stirring, fermenting the mixture in the presence of urea, processing the mixture with steam, and centrifuging the mixture to separate water and phospholipids from the fish oil. The method further includes the steps of measuring acid value of the separated fish oil to neutralize the fish oil with NaOH, washing the deaciding fish oil with warm water, and drying the washed fish oil in vacuum; mixing the dehydrated fish oil with powders of earthworm excrement to absorb the fish oil into the powders, subjecting the mixture to reaction at least 30° C. or higher for 0.5-1 hour, bleaching the fish oil absorbed into the earthworm excrement powders by use of activated clay, and filtering the bleached fish oil through a filter; and deodorizing the bleached and filtered fish oil under a steam atmosphere in a high vacuum, deodorizing apparatus, cooling and filtering the fish oil and packaging it into closed vessel. The refined fish oil is slightly improved in acid value and peroxide value and thus can be preserved freshly for a relatively long period of time without offensive fish odor.
    • 本发明公开了一种通过将新的方法引入磷脂缺乏的鱼油中制备精制鱼油的方法,该鱼油是通过在搅拌下将鱼油与谷氨酸单钠(MSG)副产物混合而获得的,并在 尿素,用蒸汽处理混合物,并将混合物离心以从鱼油中分离出水和磷脂。 该方法还包括以下步骤:测量分离的鱼油的酸值以用NaOH中和鱼油,用温水洗涤脱酸鱼油,并真空干燥洗涤过的鱼油; 将脱水鱼油与蚯蚓粪便粉末混合,将鱼油吸收到粉末中,使混合物至少在30℃以上反应0.5-1小时,通过使用漂白吸收到蚯蚓粪便粉末中的鱼油 的活性粘土,并通过过滤器过滤漂白的鱼油; 并在蒸汽气氛下在高真空,除臭装置中对漂白过滤的鱼油进行除臭,冷却并过滤鱼油并将其包装成密闭容器。 精制鱼油的酸值和过氧化值略有提高,因此可以保存在较长时间内,无异味的鱼气味。
