一、问题的提出现在各种色彩鲜艳的食物里绝大多数都添加人工合成色素.人工合成色素是以焦煤油中分离出来的苯胺染料为原料制成的.由于它成本低廉,颜色鲜艳,所以被大家广泛使用.然而许多人工合成色素除本身或其代谢产物具有毒性外,在生产过程中还可能混进砷、铅等有毒有害的中间产物.例如人工合成色素中的日落黄、苏丹红、胭脂红、人工合成苋菜红、亮蓝等,如果食用过量或食用方法不当都有可能致癌甚至致畸.

Because of its low cost, bright colors, so It is widely used by many people.However, many anthropomorphic pigments in addition to their own or their metabolites toxic, in the production process may also be mixed with arsenic, lead and other toxic and harmful intermediates, such as synthetic yellow sunset pigment, Sudan, Carmine, synthetic amaranth, bright blue, etc., if excessive consumption or improper consumption methods are likely to cause cancer or even teratogenic.
