1天然保鲜剂多菌灵、托布津等化学农药对人、畜有一定毒害作用、致畸作用;2、4-D中所含的极微量有毒物质,对人体的威胁也很大;三唑类有机化合物有一定的致癌性;残留在食品中的二氧化硫能引起严重的过敏反应。所以,使用化学药物进行果蔬防腐保鲜是没有发展前景的。应把注意力转向天然食品保鲜剂的开发和应用。

Therefore, the use of chemical drugs for preservation of fruits and vegetables is no development prospects. Attention should be turned to the development and application of natural food preservatives.
