硼氢化钾作还原剂降低高度不饱和脂肪酸乙酯中的过氧化值

Method Studies of Reducing Peroxide Value of the Highly Unsaturated Fatty Acid Ethyl Esters

利用硼氢化钾的还原性,降低主要成份为二十碳五烯酸乙酯(EPA 乙酯)和二十二碳六烯酸乙酯(DHA 乙酯)的高度不饱和脂肪酸乙酯中的过氧化值。此法以乙醇为溶剂,硼氢化钾还原剂用量≤3%,反应时间30～60min,方法简便,有显著的除过氧化物效果。

Using KBH_4 as reducing agent(3%),CH_3CH_2OH as solvent,controlling reaction time over 30—60 minutes,we tring to decrease the peroxide value of the fish oil ethyl esters (the major compositions are ethyl eicosapentaenate and ethyl docosahexaenoate,or EPA ester and DHA ester).The experimental showed that the method is very easy and the deoxide is very effective.
