中文摘要:
      目的 考察重金属含量、食品模拟物、迁移温度和迁移时间这4个因素对食品接触用银制品中Ag,As,Pb,Cd,Cr,Ni,Sb,Zn迁移量的影响。方法 试样按照充填浸泡和全浸泡的方法分别浸泡于乙酸(体积分数为4%)、乙醇(体积分数为10%,50%,95%)食品模拟物中,浸泡迁移完成后提取10 mL浸泡液用ICP-AES测定。结果 8种重金属元素中Ag,Cr,Ni,Zn被检出,重金属元素迁移量随着该元素在食品接触用银制品中含量的增高而增高;乙醇(体积分数为10%,50%,95%)食品模拟物中重金属元素迁移量较低,体积分数为4%的乙酸食品模拟物中重金属元素迁移量明显增高;8种金属元素的迁移量随着浸泡温度的升高和浸泡时间的延长而逐渐增高。结论 食品接触用银制品中8种重金属元素的迁移量与该元素在银制品中的含量有关,食品接触用银制品在接触酸性食品时存在较大质量安全隐患,很容易造成食品中Ag,Cr含量超标。为提高银制餐具的贸易销售提供了理论支持,为监管部门及时发现产品潜在安全风险提出了合理建议,也为食品接触用银制品中重金属元素迁移量的限量指标提供了数据参考。
英文摘要:
      The work aims to investigate the effects of four factors like heavy metal content, food simulants, migration temperature and migration time on the migration of Ag, As, Pb, Cd, Cr, Ni, Sb and Zn in silver products for food contact. The samples were respectively immersed in 4% acetic acid and 10% ethanol, 50% ethanol, and 95% ethanol food simulants according to the filling immersion and full immersion methods. Upon the completion of immersion migration, 10 mL of the immersion liquid was extracted and measured by ICP-AES.Among the 8 heavy metal elements, Ag, Cr, Ni and Zn were detected and the migration amount of heavy metal elements increased with the increase of the content of this element in silver products for food contact. The migration of heavy metal elements in 10% ethanol, 50% ethanol and 95% ethanol food simulants was low, and the migration of heavy metal elements in 4% acetic acid food simulants significantly increased. The migration of 8 metal elements gradually increased with the increase of the immersion temperature and the extension of the immersion time. The migration of 8 heavy metal elements in silver products for food contact is related to the content of this element in silver products. Silver products for food contact have a large hidden danger of quality and safety when coming into contact with acidic foods, which can easily lead to excessive levels of Ag and Cr in food. This study provides theoretical support for increasing the trading and sales of silver tableware and improving the commercial sales of silver tableware, puts forward reasonable suggestions for regulatory authorities to discover potential product safety risks in a timely manner, and provides reference data for the limited index of migration of heavy metal elements in silver products for food contact.
