| 摘 要： | 用三维荧光光谱法对葵花籽油中掺入少量地沟油进行了检测．结果表明，当加入地沟油的体积分数φ〉10％时，在λex=310nm，λem=345nm处，葵花籽油相对荧光强度I由7673迅速下降至3555，与新鲜葵花籽油相比，荧光强度下降了4118，由此可作为葵花籽油中是否掺入地沟油的判据．该方法灵敏、稳定，适合于葵花籽油中掺杂少量地沟油的测定．

| Abstract: | The three-dimensional fluorescence spectrometry was successfully used to detect a spot of hogwash oil mixed in sunflower seed oil. Experiment results showed that the fluorescence intensity decreased from 7 673 to 3 555 in λex= 310 nm and λem= 345 nm respectively, when adding more than 10% of hogwash oil in fresh oil. The fluorescence intensity decreased nearly 4 118, which could be used as a criterion to verdict whether a fresh sunflower seed oil mixed with hogwash oil or not. This method is relatively sensitive, stable and suitable for detection of little hogwash oil mixed with fresh sunflower seed oil. |
