摘要
目的对欧洲李中As、Hg、Cd、Pb、Cu等重金属及有害元素进行含量测定,并对其进行安全风险评价。方法采用原子吸收分光光度法进行含量测定;根据世界卫生组织/联合国粮农组织食品添加剂联合专家委员会制定的暂定每周可耐受摄入量(PTWI),计算每日理论最大摄入量(TMDI),说明其摄入的安全性风险。结果所测15批欧洲李样品中重金属及有害元素As、Hg、Cd、Pb、Cu的含量均较低,不同批次的欧洲李样品重金属及有害元素含量存在差异。理论上,当人每日摄入欧洲李低于399.87g时,从其中摄入的重金属及有害元素含量不会超过日耐受摄入量MTDI;经综合考虑,建议欧洲李的日摄入量不超过100g。结论本研究为欧洲李安全食用及可持续生产提供一定的理论指导。
Objective This paper aims to determine the contents of heavy metals and harmful elements such as lead,cadmium,copper,arsenic and mercury in Prunus domestica L.,and to evaluate the safety risk of Prunus domestica L..Methods The contents of lead,cadmium,copper,arsenic and mercury were determined by atomic absorption spectrometry（AAS）.According to WHO/FAO joint FAO/WHO JECFA recommendatory provisional tolerable weekly intake（PTWI）,the theoretical maximum daily intake（TMDI）was calculated to evaluate the safety risk of Prunus domestica L..Results The contents of lead,cadmium,copper,arsenic and mercury detected in 15 batch Prunus domestica L.samples were low,and they were different in the contents of heavy metals and harmful elements in the samples from different batches.In theory,when people daily intake of Prunus domestica L.is below399.87 g,the heavy metals and harmful elements intake does not exceed the maximum tolerable daily intake（MTDI）.Through comprehensive consideration,we recommended that the daily intake of Prunus domestica L.is not more than 100 g.Conclusion This study offered a theoretical guidance for the safe consumption and sustainable production of Prunus domestica L..
