| Abstract: |
| 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. |
