辐照食品毒性危害的评价步骤,逻辑上应类似于对单一化学物质毒性危害的评价。但在采取的方法中有些差异,其原因首先是食品本为化学混合物,经加工后成分进一步复杂化,所产生的可能为有毒有害化学复合物,一时还不可能进行定性和定量测定;其次,动物实验结果易受营养、环境、毒物接触量及食物成分化学变化诸因素的影响;第三,由于流行病学研究 The evaluation procedure for the toxicity of irradiated food should be logically similar to the evaluation of the toxicity of a single chemical substance. However, there are some differences in the methods adopted because the food is the chemical mixture first, and the components further complicated after processing may produce toxic and harmful chemical complexes, so it is impossible to conduct qualitative and quantitative determination in a moment. Secondly, Animal experiment results are susceptible to nutrition, environment, exposure to toxicants and chemical composition of food ingredients; Third, due to epidemiological studies
