| description | The invention relates to a low-arsenic antarctic krill oil composition and a preparation method therefor. The composition is prepared through the following steps: (1) washing a raw material with an aqueous solution of ethanol, and then, carrying out extraction by a mixed solvent of ethyl acetate and ethanol which are in any ratio; (2) removing arsenic from an extract by an adsorbent; and (3) carrying out molecular distillation to remove the solvent. The preparation process is simple in operation and low in energy consumption, the obtained product is low in total arsenic content and high in phospholipid content and is rich in a variety of beneficial ingredients such as astaxanthin and omega-3 fatty acids (EPA and DHA), and thus, the preparation method is an effective mode for obtaining antarctic krill oil with low total arsenic content.
低砷南极磷虾油组合物及其制备方法，所述组合物通过下述方法制备：(1)以乙醇水溶液洗涤原料后，以乙酸乙酯和乙醇按照任意比例的混合溶剂提取；(2)提取液以吸附剂除砷；(3)分子蒸馏脱除溶剂。本制备工艺操作简单，耗能低，所得产品总砷含量低，磷脂含量高并且富含虾青素以及ω-3族脂肪酸(EPA以及DHA)等多种有益成分，是种有效的获取低总砷含量南极磷虾油的方式 |
