| 中文摘要: |
| 为了对油菜籽制油与饼粕加工过程中的危害因子与抗营养因子的控制提供基础数据与参考，研究了油菜籽皮仁中重金属、多环芳烃和硫苷含量的差异及分布规律。结果表明：油菜籽中镉（Cd）和砷（As）平均含量分别为33.75、29.10 μg/kg，主要分布于油菜籽皮中；油菜籽铅（Pb）含量为22.48~359.17 μg/kg，在油菜籽皮仁中的分布规律不明显；苯并（a）芘和4种多环芳烃（苯并（a）芘、苯并（a）蒽、和苯并（b）荧蒽）主要分布在油菜籽皮中，苯并（a）芘在所有的油菜籽样品中均有检出，平均含量为0.57 μg/kg，最小值和最大值分别为0.27 μg/kg和0.98 μg/kg；所测油菜籽中主要的硫苷种类为2-羟基-3-丁烯基硫苷和3-丁烯基硫苷，油菜籽皮中的硫苷含量低于油菜籽仁中的含量。 |

| In order to provide basic data and reference for the control of hazard factors and anti-nutritional factors in the process of rapeseed oil and meal processing, the content and distribution of heavy metals, polycyclic aromatic hydrocarbons and glucosinolates in rapeseed hulls and kernels were studied. The results showed that the average contents of cadmium (Cd) and arsenic (As) in rapeseed were 33.75 μg/kg and 29.10 μg/kg, respectively, which were mainly distributed in the rapeseed hulls. The plumbum (Pb) content was 22.48-359.17 μg/kg in rapeseed and it was randomly distributed in the hulls and kernels of rapeseed. Benzo(a)pyrene and four kinds of polycyclic aromatic hydrocarbons (benzo(a)pyrene, benzo(a)anthracene, chrysene and benzo(b)fluoranthene) were mainly distributed in rapeseed hulls. Benzo(a)pyrene was detected in all rapeseed samples with an average content of 0.57 μg/kg, and the minimum and maximum contents of benzo(a)pyrene were 0.27 μg/kg and 0.98 μg/kg, respectively. The main glucosinolates in the tested rapeseed were 2-hydroxy-3-butenyl glucosinolate and 3-butenyl glucosinolate, and the glucosinolates content in rapeseed hulls was lower than that in rapeseed kernels. |
