蜜饯食品中乙二胺四乙酸二钠的检测与风险评估

Detection analysis and health risk assessment of ethylenediaminetera acetic acid disodium in preserved fruits

以了解蜜饯食品中乙二胺四乙酸二钠的残留情况及评估其对人体的健康风险为目的。采用高效液相色谱法对深圳流通市场抽检的572件蜜饯产品(包括地瓜果脯类51件,其他蜜饯521件)进行检测,并在此基础上进行人体的健康风险评估。结果表明,有80.40%的地瓜果脯样本使用了乙二胺四乙酸二钠护色防腐,另有3.07%的其他蜜饯超范围使用了乙二胺四乙酸二钠,特别是地瓜类果脯呈现EDTA高检出率的特点。从蜜饯食品中乙二胺四乙酸二钠的风险评估结果得出,目前深圳各年龄段人群对来源于地瓜果脯和其他蜜饯中EDTA暴露水平均处于安全范围,依据乙二胺四乙酸二钠ADI值推算的最大蜜饯摄入量远高于人民日常消费摄入量,风险较小,但仍需控制儿童青少年及育龄女性对此类食品的摄入。该研究为消费者和监管部门提供参考依据。

The research is to study the residual content of disodium ethylenediamine tetraacetate in preserved fruits and its risk to human health. The high performance liquid chromatography method was used to test 572 samples （including 51 preserved sweet potatoes and 521 other preserves） in Shenzhen market, the human health risk assessment of these residues were also carried out. The results showed that 80.4 % of preserved sweet potato samples have EDTA, and 3.07 % of other preserved fruits over used EDTA. The risk assessment of EDTA shows that people of all ages in Shenzhen on average are in the safe range of EDTA exposure from preserved fruits including sweet potatoes. The maximum intake of preserves calculated based on EDTA ADI is still much higher than the actual daily consumption. Therefore, the risk is small. However, the intake of such foods by children and adolescents and women of childbearing age still needs to be controlled. The study provides a reference for consumers and regulators.
