中文摘要:
      目的 以咖啡粉用不锈钢量匙为例,研究量匙在重复使用条件下与真实食品接触时的迁移行为,为正确使用不锈钢食具和相关决策制定提供数据参考。方法 采用电感耦合等离子体质谱方法(ICP-MS),研究重复使用次数、咖啡粉开封时间对收集的3种咖啡粉用不锈钢量匙中铅、镍、铬、镉、砷等5种元素迁移规律的影响,且对比分析标准条件和实际使用条件下元素迁移行为的差异。结果 咖啡粉用不锈钢量匙中元素的累积迁移量随重复使用次数增加显著,随咖啡粉开封时间小幅增加,重复使用1000次的元素累积迁移量相当于重复使用100次的2~3倍,明显超标的镍元素可高达12倍;另外,不锈钢量匙在体积分数为4%乙酸模拟液标准条件下的元素迁移量高于与咖啡粉重复接触100次的累积迁移量,但低于重复接触1000次的累积迁移量。结论 在一定范围内,不锈钢制品的标准迁移条件比真实食品接触条件更为苛刻,然而在日常使用中,尚需注意不锈钢食具与同一食品反复接触过多次时所累积的潜在危害。
英文摘要:
      Reusing is the main characteristic of food-contact stainless steel products. The work aims to study the migration in spoon under reused conditions and in contact with food by taking the stainless steel spoon for coffee powder as an example, so as to provide some references for correctly using stainless steel utensils or making relevant decisions. Inductively coupled plasma mass spectrometer (ICP-MS) was used to study the influence of reused cycles and unsealed time of coffee powder on the migration rules of lead, nickel, chromium, cadmium and arsenic in 3 stainless steel spoons for coffee powder and compare the difference of the migration behaviors of elements under standard conditions and actual conditions. The cumulative migration of elements in the coffee spoon increased significantly with the increasing reused cycles, and slightly increased with the extending coffee unsealed time. The cumulative migration of elements for 1000 reused cycles was 2~3 times of that for 100 repeated cycles. The migration of nickel (exceeding the standard value) could be up to 12 times. In addition, the migration under the standard condition of 4% acetic acid simulated solution was higher than that of 100 reused cycles, but lower than that of 1000 reused cycles. In general, the standard migration condition of stainless steel products is more severe than that of real food contact within a certain range. In daily use, special attention needs to be paid to the potentially accumulated harm when the stainless steel utensils are excessively repeated to contact with the same food.
