摘要
目的研究餐具的使用和清洗方法对餐具中甲醛、重金属迁移量的影响,降低消费者的使用风险。方法通过研究密胺餐具经过极端不当条件使用后甲醛迁移量的变化和有、无图案印刷密胺餐具的重金属迁移量,对各种条件下密胺餐具的使用方式进行风险评估。结果经过微波炉使用(中火)、钢丝球擦洗(10次)、模拟蒸煮温度使用(100℃)后,密胺餐具的甲醛迁移量均显著增高。食品接触面有图案印刷和无图案印刷密胺餐具中的重金属(As,Pb,Cd)迁移量变化不大,均低于国家标准要求。结论不正确的使用密胺餐具,如微波炉使用、反复利器擦洗、蒸煮使用后,甲醛迁移量均会明显增大,甚至超过标准限量值,造成极大的安全隐患,存在极高风险。
The paper aims to study the effects of the use and cleaning methods of tableware on the migration of formaldehyde and heavy metals in tableware,and reduce the risk of consumer use.By studying the change of formaldehyde migration amount and heavy metal migration amount of melamine tableware with and without pattern printing after using in extreme improper conditions,the risk assessment of the use mode of melamine tableware under various conditions was carried out.The formaldehyde migration amount of melamine tableware was significantly increased after microwave oven with medium fire,steel wire ball scrubbing for 10 times or simulated cooking temperature c.a.100℃.Migration of heavy metals(As,Pb and Cd)from melamine tableware with printing pattern against food contact surface was far lower than the limit of national standards,as well as those without printing pattern.Improper use of melamine cutlery such as microwave ovens,repeated sharp scrubbing,cooking use of formaldehyde migration will obviously increase the formaldehyde migration,or even make it exceed the standard limit value,resulting in great safety risks.There is a very high risk.
