    摘要: An efficient and simple process to obtain a concentrate that comprising over 80% in weight of ethyl esters of ω-3 fatty acids based on a composition of matter that contains esters of ω-3 fatty acids or free ω-3 fatty acids that comprises the steps of:
    a) contacting the composition of matter with ethanol of at least 96% in weight and a hydroxide of an alkali metal at a temperature between 60 and 200 °C to form a liquid mixture comprising alkaline salts of fatty acids;
    b) cooling the liquid mixture to a temperature between soft and -20 °C to form a solid phase and a liquid phase and separate the liquid phase from the solid phase;
    c) contacting the separated liquid phase of step b) with an acid to form an acidified mixture with a water content under 10%, where the mixture consists of a solid phase that includes the alkali metal salt of the acid and a liquid phase comprising ω-3 fatty acids;
    d) heating the mixture of step c) between 50 to 150 °C in the presence of an esterification catalyst to form a mixture comprising ethyl esters of ω-3 fatty acids;
    e) contacting the mixture of stage d) with an alkali to form a neutralized mixture;
    f) distilling the neutralized mixture to obtain a distillate that includes over 80% in weight of ethyl esters of ω-3 fatty acids.
