    Rapeseed oil contains a special fatty acid, erucic acid, can have adverse effects on human nutrition, inhibits the growth of thyroid hypertrophy, and other side effects. The traditional high erucic acid rapeseed oil and erucic acid content is between 20% and 55%, now has not eaten as raw materials, and used for making lubricant. After the plant variety improvement of rapeseed oil content of erucic acid in 5% or not containing erucic acid.

     

    Tengzhou Xiangying Analysis Technology Co. Ltd by GC7990 capillary column, explores the chromatographic conditions for the separation and determination of erucic acid. The external standard method for quantitative, in 0.26 ~ 2.6 g range, the peak area of Y methyl erucate and amount of sample X has a good linear relationship, the regression equation is Y=12.81+3.89 * 10~5X, the linear correlation coefficient r=0.999. Of 6 samples of imported Edible Rapeseed Oil Determination of erucic acid content, results in 0.4% ~ 3.1%.


    菜籽油中含有一种特殊的脂肪酸—芥酸,能对人体的营养状况产生不良影响,有抑制生长,引起甲状腺肥大等副作用。传统的高芥酸菜子油芥酸含量在20%一55%之间,现在已不作为食用,而用作制作润滑剂的原料。经过植物品种改良的菜子油芥酸含量在5%以下或不含有芥酸。
    滕州市翔鹰分析技术有限公司采用GC7990毛细管色谱柱,对分离测定芥酸的色谱条件进行了探索。以外标法定量,在0.26~2.6μg范围内,芥酸甲酯的色谱峰面积Y与进样量X具有良好的线性关系,其回归方程为Y=12.81+3.89×10~5X,线性相关系数r=0.999。对6份进口食用菜籽油进行芥酸含量测定,结果在0.4%~3.1%之间。
