中文摘要:

      许多农药、兽药、毒素、食品添加剂、重金属、环境污染物等外源物质不但本身有一定毒性, 污染食品后对人体造成危害, 而且在食品加工过程中也会发生变化而导致食品的二次污染, 可能分解为毒性更强的物质, 或与食品内源组分发生反应产生新的有害物质, 或与其他物质之间存在毒性协同增强作用等。实际上, 大量的外源物质在食品加工过程中的变化与安全性问题尚未研究。本文对该领域的研究进展进行了综述, 期望引起相关研究者的重视。

英文摘要:

      The residues of exogenous chemical compounds such as pesticides, veterinary drugs, mycotoxins, food additives, heavy metals and environmental pollutants in foods are harmful to human health. Moreover, some compounds may transform to new noxious substance during food processing and result in second contaminant. For example, some compounds may degrade during food processing and form noxious deg-radation products, and some may react with food components to form new noxious substance and some may result in synergistic effect with other noxious substance. These problems have not been received full attention. Therefore, current trends on the transformation of exogenous chemical compounds during food processing and the safety of transformation products were summarized in this review.
