摘要
目的:研究影响二十二碳六烯酸(DHA)和二十碳五烯酸(EPA)氧化发生的因素,寻找其高效的抗氧化剂。方法:以DHA、EPA质量为指标,温度、光照、时间为考察因素,采用正交试验法,优选对DHA、EPA氧化影响最小的条件;通过对样品添加红景天苷、丁基羟基茴香醚(BHA)、二丁基羟基甲苯(BHT)、维生素E 4种抗氧化剂,筛选最强抗氧化剂。结果:温度越低、光照越弱、时间越短,DHA、EPA氧化越慢;红景天苷对DHA、EPA的抗氧化作用最强。结论:通过降温、避光、减少储存时间、添加红景天苷的方法可以减弱DHA、EPA的氧化。
OBJECTIVE： To study the influence factors of the oxidation of DHA and EPA,and to find effective antioxidants.METHODS： The oxidation of DHA and EPA was optimized by orthogonal test with the quality of DHA and EPA as indicators and temperature,light and time as factors.The optimized antioxidants were selected by adding salidroside,BHA,BHT,vitamin E into samples.RESULTS： If there is lower temperature,weaker light and shorter storage,the oxidation of DHA and EPA will be more slowly.Effect of salidroside on the oxidation of DHA and EPA is the strongest.CONCLUSION： The oxidation of DHA and EPA can be reduced by lowering temperature,storing in dark place,reducing storage duration and adding salidroside.
