| Abstract: |
| In order to research the migration property of metallic elements in edible vegetable oil raw material and products produced by different processes, and control the quality of edible vegetable oil, the contents of seven metallic elements were determined using atomic absorption spectroscopy after dry digestion. The results showed that chromium was the key control element affecting the quality of edible vegetable oil because it had the highest migration rate in edible vegetables oils. Metallic elements mainly kept in meal and cake, and the migration rate from raw materials to oil was relatively low. In addition, the correlation between the metallic elements level and different preparation processes of edible vegetable oil was weak on the whole. |
