硒对茶油中反式脂肪酸的形成影响研究

Effect of selenium on the generation of trans fatty acids in tea seed oil

  • 摘要: 研究了硒对茶油中反式脂肪酸产生的影响。采用向茶油中加入不同量亚硒酸钠,改变加热温度和时间以影响反式脂肪酸的生成,用气相色谱监测茶油中反式油酸和反式亚油酸的含量变化。研究结果表明:在加热条件下,随着茶油中硒含量的增加,反式油酸和反式亚油酸的含量逐步增加,反式脂肪酸含量达到30.27%。硒能促使反式脂肪酸的产生,不能向茶油中添加硒。 

     

    Abstract: The effect of selenium on the generation of trans fatty acids in tea oil was investigated in detailed. With adding different amounts of sodium selenite in tea seed oil, changing heating temperature and heating time, the content of trans oleic acid and trans-linoleic acid was monitored by gas chromatography.The results showed that selenium salts should not be added into tea seed oil because the contents of the trans- oleic acid and trans-linoleic acid increased with the adding of selenium saltunder heated conditions and the trans fatty acid content reached 30.27% and selenium salt could promote the generation of trans fatty acids.,
