摘　　要：对宁夏、甘肃、青海、新疆、内蒙古生产的枸杞进行随机抽样,依据《食品安全国家标准食品中二氧化硫的测定》(GB 5009.34—2022)采用酸碱滴定法测定二氧化硫残留量,并利用危害商值法进行风险评估。结果显示,不同产地枸杞中二氧化硫残留量存在差异,部分产地有少量枸杞样品超出国家标准限量(100 mg·kg^(-1))。其中,宁夏中宁产地枸杞中二氧化硫残留量均值为20.5 mg·kg^(-1),甘肃靖远产地均值为39.8 mg·kg^(-1),新疆和田产地均值为19.1 mg·kg^(-1),青海格尔木产地均值为4.62 mg·kg^(-1),内蒙古巴彦卓尔产地均值为0.98mg·kg^(-1)。风险评估表明,长期或过量摄入二氧化硫含量过高的枸杞可能对人体健康造成潜在危害。本研究为枸杞质量安全监管和消费者健康饮食提供了科学依据。The wolfberries produced in Ningxia,Gansu,Qinghai,Xinjiang and Inner Mongolia were randomly sampled,and the sulfur dioxide residue was determined by acid-base titration according to GB 5009.34—2022,and the risk assessment was performed using the hazard quotient method.The results showed that there were differences in the sulfur dioxide residue in wolfberries from different origins,and a small number of wolfberry samples from some origins exceeded the national standard limit(100 mg·kg^(-1)).Among them,the average sulfur dioxide residue in wolfberries from Zhongning,Ningxia was 20.5 mg·kg^(-1),the average sulfur dioxide residue in Jingyuan,Gansu was 39.8 mg·kg^(-1),the average sulfur dioxide residue in Hetian,Xinjiang was 19.1 mg·kg^(-1),the average sulfur dioxide residue in Golmud,Qinghai was 4.62 mg·kg^(-1),and the average sulfur dioxide residue in Bayannur,Inner Mongolia was 0.98 mg·kg^(-1).The risk assessment showed that long-term or excessive intake of wolfberries with high sulfur dioxide content may cause potential harm to human health.This study provides a scientific basis for wolfberry quality and safety supervision and consumers’healthy diet.
