[Objective]The research aimed to understand the residual sulfur dioxide in sweetmeat and assess the risk of the residues to human health.[Method]The sweetmeat taken from markets and small shops was studied by distillation-titration method.The health risk on human was e-valuated by questionnaire and the point evaluation method based on the content of sulfur dioxide.[Result]Sulfur dioxide residue testing results showed that there were four kinds of sweetmeat easily exceeded, among which prunes and dried apricots were more easily exceeded.The mean value of sulfur dioxide residue in prunes and apricots was 0.82 and 0.63 g/kg respectively, which was more than twice the standard limit (0.35 g/kg)for the state.Exposure assessment results showed that prunes and dried apricots had a certain risk to the human body,the risk value for children was bigger,the risk quotient value HQ was greater than 1 and adult female also had greater risks, the HQ from prunes was much greater than 1,the HQ from apricots was also slightly greater than 1.[Conclusion]The study provides a reference for consumers and regulators.%[目的]了解蜜饯食品中二氧化硫的残留状况和评估其残留量对人体健康的风险.[方法]采用蒸馏-滴定法对所抽检的蜜饯进行了检测,并在此基础上结合问卷调查和点评估法,进行了人体的健康风险评估.[结果]二氧化硫残留量的检测结果表明,有4类蜜饯食品容易超标,其中梅干和杏干是属于二氧化硫残留量更为容易超标的食品,其二氧化硫残留量平均值分别为0.82和0.63 g/kg,基本上为国家规定标准限量(0.35 g/kg)的2倍以上;暴露评估的结果表明,梅干和杏干对人体具有一定的风险,风险较大的是少年儿童,其风险商值(HQ)均大于1,且成年女性也有较大的风险,其来源于梅干的HQ远大于1,来源于杏干的HQ也是略大于1.[结论]该研究为消费者和监管部门提供参考依据.
